<h3 class="wp-block-heading" id="h-the-challenge-brittle-electrodes-vs-deformable-needs">The challenge: Brittle electrodes vs. deformable needs</h3>



<p>The rise of wearables, from fitness trackers to smart clothing, has necessitated a shift in how we store energy. Traditional batteries, while effective, often lack the flexibility required for these soft electronic devices. Micro supercapacitors (MSCs) have emerged as a promising alternative due to their high power density, rapid charging capabilities, and long lifespan. However, a major hurdle remained: the fabrication of electrodes.</p>



<p>Conventionally, electrodes are made from brittle materials like gold, which significantly limit the device&#8217;s ability to deform without compromising performance. Conversely, while eutectic gallium-indium liquid metal (EGaIn) offers superior conductivity and deformability, its high surface tension makes fine patterning, a crucial step in creating efficient electrodes, extremely difficult.</p>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="2000" height="1815" src="https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_7baf54.png?w=1190" alt="" class="wp-image-61305" srcset="https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_7baf54.png 2000w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_7baf54.png?resize=300,272 300w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_7baf54.png?resize=768,697 768w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_7baf54.png?resize=1190,1080 1190w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_7baf54.png?resize=1536,1394 1536w" sizes="(max-width: 2000px) 100vw, 2000px" /><figcaption class="wp-element-caption"><em>Fabrication process for deformable micro-supercapacitors</em>. <em><a href="https://www.nature.com/articles/s41528-024-00306-2/figures/1"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">Credits: POSTECH</a></em></figcaption></figure>



<h3 class="wp-block-heading">A laser-sharp solution: Patterning the way for flexible power</h3>



<p>The research team, led by Professor Jin Kon Kim and Dr. Keon-Woo Kim from Pohang University of Science and Technology (POSTECH) in collaboration with Dr. Chanwoo Yang and Researcher Seong Ju Park from the Korea Institute of Industrial Technology (KITECH), devised a solution using laser technology. Their innovation lies in the successful laser patterning of both EGaIn and graphene, an active material, on a stretchable substrate made of polystyrene-block-poly(ethylene-co-butylene)-block-polystyrene copolymer (SEBS).</p>



<p>This laser ablation technique offered several advantages. Notably, it ensured the underlying SEBS substrate remained undamaged, preserving the device&#8217;s overall flexibility. Additionally, tests revealed that the areal capacitance, a measure of the device&#8217;s energy storage capacity per unit area, remained unchanged even after undergoing 1,000 stretching cycles. Furthermore, the researchers observed stable operation under various mechanical deformations, including stretching, folding, twisting, and wrinkling.</p>



<h3 class="wp-block-heading" id="h-implications-for-wearable-tech">Implications for wearable tech</h3>



<p>This breakthrough holds immense potential for the future of wearable technology. As Professor Jin Kon Kim aptly stated, &#8220;The use of laser-patterned liquid metal electrodes represents a significant step forward in the development of truly deformable energy storage solutions.&#8221; This innovation paves the way for the creation of comfortable and adaptable wearables that can seamlessly integrate into our dynamic lifestyles.</p>



<p>Imagine thinner fitness trackers that comfortably wrap around your wrist during exercise, smart clothing that moves with you throughout the day, or medical devices that conform to the body for a more comfortable and personalized experience. With this research, the future of <a href="https://interestingengineering.com/innovation/uclas-ai-wearable-empowers-speech-for-vocal-cord-impairments"  target="_blank"  rel="dofollow">wearable technology</a> looks brighter and more flexible than ever before.</p>

<p>The shocking scam began on Instagram, where the victim, a big fan of the Tesla CEO, received a friend request from a profile claiming to be Musk.</p>


South Korean woman falls for deepfake Elon Musk, loses $50K in romance scam

Representational image: A portrait of SpaceX CEO Elon Musk. 


<p>Deepfake technology is doing rounds for its misuse, and a South Korean woman is the latest victim of it. <br><br>Recently, the woman, who wishes to remain anonymous, said she was tricked into giving $50,000 to someone who pretended to be <a href="https://interestingengineering.com/innovation/tesla-optimus-sale-elon-musk"  rel="dofollow">Elon Musk</a>. </p>



<p>According to the local media, the woman was duped by a deepfake video featuring the Tesla CEO. Meanwhile, the victim has shared her experience on a South Korean TV show to warn others.</p>



<h3 class="wp-block-heading" id="h-setting-up-the-stage">Setting up the stage</h3>



<p>The shocking scam began on Instagram, where the victim, a big fan of the Tesla CEO, received a friend request from a profile claiming to be Musk.</p>



<p>“I experienced something like a dream last year,” she said in her interview.&nbsp;</p>



<p>At first, the woman became skeptical when the person claiming to be the tech billionaire contacted her through Instagram.</p>



<p>“On July 17, ‘Musk’ added me as a friend on Instagram. Although I have been a huge fan of Musk after reading his autobiography, I doubted it at first,” she added.</p>



<p>However, the scammer continued to convince her by sharing images of Musk at work and photos of his official ID.</p>



<h3 class="wp-block-heading">Clearing all doubts</h3>



<p>He made the impersonation more convincing by detailing personal stories of Musk&#8217;s life. According to the woman, they talked about Musk&#8217;s children and his daily work routine at companies like Tesla and <a href="https://interestingengineering.com/science/nasa-mars-sample-retrieval"  rel="dofollow">SpaceX</a>.</p>



<p>&#8220;&#8216;Musk&#8217; talked about his children and about taking a helicopter to work at Tesla or SpaceX,&#8221; she said.</p>



<p>The scammer even told the woman about a meeting between Musk and South Korean President Yoon Suk Yeol in April 2023. He said the meeting was about building Tesla&#8217;s Gigafactories in Seoul and Jeju.</p>



<p>Trust was further established during a deepfake video call where the scammer, disguised as Musk, expressed romantic interest.</p>



<p>“‘Musk’ even said, ‘I love you, you know that?’ when we made a video call,” she claimed.</p>



<h3 class="wp-block-heading">The investment trap</h3>



<p>The scammer then presented Ms. Jeong with a fraudulent investment opportunity, claiming to enrich his dedicated fans. <br><br>&#8220;He also explained that he contacts fans randomly,&#8221; narrated the victim. </p>



<p>“‘I’m happy when my fans are getting rich because of me,’” the scammer reportedly told the victim. Thereafter, the conman shared a Korean bank account number and convinced the woman to transfer $50,000.</p>



<h3 class="wp-block-heading">Not the first incident</h3>



<p>These romance scams are common. People in the US lost $1.3 billion to these tricks in 2022. Besides, this isn&#8217;t the only time someone has pretended to be Elon Musk.</p>



<p>Earlier, Yilong Ma, a Chinese man who resembles Musk, became famous on TikTok. Even the real Elon Musk noticed him and wasn&#8217;t sure if the Chinese man was real.</p>



<p>&#8220;I&#8217;d like to meet this guy (if he is real). Hard to tell with deepfakes these days,&#8221; <a href="https://twitter.com/elonmusk/status/1523656160699502593?s=20"  rel="noopener noreferrer nofollow" target="_blank">Musk said of Ma on X</a>.</p>



<p>Also, in 2021, a UK school teacher fell victim to a Bitcoin scam claiming Musk would double her investment, resulting in substantial financial losses.</p>

<p>The researchers found a resilient group of bacteria thriving in the extreme depths of bone-dry Yungay Valley.</p>


Secret biosphere found 13 feet below world&#8217;s driest hot desert


<p>As they say, life finds a way. Microbial life has been discovered existing 13 feet beneath the surface of Earth&#8217;s most hostile desert, the Atacama in northern Chile.   </p>



<p>It is known as the world&#8217;s driest scorching desert, with the sun beating down fiercely and life seems implausible.&nbsp;</p>



<p>The researchers found a resilient group of bacteria thriving in the extreme bone-dry Yungay Valley. This microbial community is completely isolated from the surface world.&nbsp;</p>



<p>&#8220;To our knowledge, this represents the deepest microbial survey and discovery of microbial life in Atacama soils to this day,&#8221; the study authors mentioned. </p>

<h3 class="wp-block-heading" id="h-extraction-of-samples">Extraction of samples </h3>



<p>Higher living forms struggle to survive in the Atacama Desert&#8217;s super-arid conditions. Despite the rough environment, microbial life thrives in the desert&#8217;s salty and sulfate-rich soil. These conditions provide a unique environment for some types of microorganisms to live.</p>



<p>Microbes have previously been documented in the desert region to depths of 2.6 feet (80 centimeters). The press release noted that “the first 80 centimeters of soil is thought to be a possible refuge from harsh UV light, a place where some water might be found.”&nbsp;</p>



<p>However, researchers have wondered if the microbes could survive in deeper soil layers. To examine this, Dirk Wagner and colleagues collected deep subsurface soil samples from the Yungay Valley portion of the desert. </p>



<p>To uncover this hidden biosphere, researchers used a novel extraction procedure that ensured the DNA recovered was from living organisms.</p>



<p>They discovered that microbial life extends from depths of 6.6 feet to at least 13 feet deep below the <a href="https://interestingengineering.com/science/desert-bacteria-solar-energy"  target="_blank"  rel="dofollow">desert</a>&#8216;s surface.</p>



<h3 class="wp-block-heading">Types of microbes found</h3>



<p>Firmicute phylum microbes were prevalent in the upper 80 cm of playa sediments. Below 200 cm, a distinct microbial population was observed, dominated by Actinobacteria.</p>



<p>The team found bacteria from the phylum Firmicutes, which are resistant to high salt content and thrive in less oxygen. Actinobacteria are known to live in various harsh conditions, including the Arctic and other salty habitats.  </p>

<h3 class="wp-block-heading" id="h-how-do-microbes-survive-at-these-depths">How do microbes survive at these depths?</h3>



<p>During the genetic analysis of the <a href="https://interestingengineering.com/innovation/microbial-mining-colonize-moon-mars"  target="_blank"  rel="dofollow">microbial</a> communities, some bacteria exhibited genetic similarities to two specific species: <em>Geodermatophilus pulveris and Modestobacter caceresii.</em> Both types of bacteria belong to the Actinobacteria phylum. </p>



<p>The authors have suggested that this community of bacteria [Actinobacteria] might have colonized the soil 19,000 years ago, &#8220;before being buried by playa deposits, and hypothesize that the community could continue downwards for an indefinite distance, representing a previously unknown deep biosphere under hyper-arid desert soils.”</p>



<p>But how could this microbial colony thrive at such extreme depths? The team suggests they do so by obtaining water from mineral gypsum.&nbsp;</p>



<p>The implications of this discovery extend far beyond Earth. The Atacama Desert resembles a <a href="https://interestingengineering.com/science/mysterious-soil-found-in-chile-points-to-possible-life-on-mars"  target="_blank"  rel="dofollow">Martian landscape</a> with its barren, lifeless terrain. </p>



<p>But there is a tantalizing possibility under the Martian soil: gypsum deposits, similar to those discovered in the Atacama, might provide water for microbial life.</p>

<p>A new approach for generating lab grown diamonds could help deliver thin layers of diamonds to be used in a range of devices and sensors. </p>


Diamonds grown in lab within minutes without extreme pressure 

Lab grown diamonds can now be generated faster and with exceeding demands of pressure conditions. 


<p>A research team led by Rod Ruoff at the Institute of Basic Science (IBS) at the Ulsan National Institute of Science and Technology (UNIST) in South Korea has developed a new approach to making diamonds in the lab without extreme pressure. </p>



<p>The approach could help synthesize larger-sized diamond crystals and extended films with extensive applications in optics and advanced electronics, as per the researchers. </p>



<p>Lab-grown or artificial diamonds aren&#8217;t a new discovery. General Electric discovered this technique nearly 50 years ago using molten iron sulfide. The High-Pressure, High-Temperature (HPHT) method replicates the natural conditions in the Earth&#8217;s mantle where <a href="https://interestingengineering.com/science/how-do-diamonds-really-form-not-from-coal"  target="_blank"  rel="dofollow">diamonds are naturally formed</a>. </p>



<p>When temperatures reach 2552 degrees Fahrenheit (1400 degrees Celsius) and pressure is at least five gigapascals (1 Pa = 10,000 atm), the liquid metal turns into diamonds. </p>



<p>The other approach, chemical vapor deposition (CVD), is less demanding regarding pressure but requires special semiconductor fabrication equipment to carry out the process. </p>



<p>Both approaches also use a diamond seed to help kickstart diamond formation. However, the UNIST team&#8217;s approach does away with this requirement and puts these diamonds at normal atmospheric pressure. </p>



<h3 class="wp-block-heading">Synthesizing diamonds at normal pressure</h3>



<p>Many years ago, Ruoff noticed that the synthesis of diamonds may not need higher pressures. A 2017 study showed that liquid gallium dissolves carbon atoms and binds them into a solid sheet-like graphene when exposed to methane gas. </p>



<p>Ruoff believed that under the right conditions, this process could also result in diamonds and began working on developing it. </p>



<p>Initially, the researchers added droplets of molten gallium and other metals, exposing the mix to carbon-related gases. When a blob of molten gallium accidentally spilled over a layer of pure silicon and dissolved it, the researchers found a collection of tiny diamond crystals in the hardened metal. </p>



<p>Further refinements of the approach have now led to a recipe in which a mix of liquid gallium, silicon, iron, and nickel heated in a small crucible to 1877 Fahrenheit (1025 degrees Celsius) and exposed to methane and hydrogen gases forms the pyramidal arrangement seen in diamonds. No diamond seed is needed for this process. </p>

<h3 class="wp-block-heading" id="h-making-diamonds-in-minutes">Making diamonds in minutes</h3>



<p>In the earlier experiments, the researchers used a large chamber dubbed RSR-A with an interior volume of 26 gallons (100 liters). For effective exposure to methane and hydrogen gases, the team had to first empty the chamber of air, then fill it up with an inert gas, and then empty it again to a vacuum level before the mixture of gases could be pumped in at the required atmospheric pressure. </p>



<p>Due to the chamber&#8217;s large volume, these steps took about three hours to complete before the experiment could even be attempted. </p>



<p>Ruoff then had the idea to reduce the volume of the chamber to quicken these processes and built a new chamber, RSR-S, with an interior volume of just over two gallons (nine liters); the process can now be completed in just 15 minutes. </p>



<p>The research is still in its early stages. Still, it paves the way for the production of thin films of diamonds that can be <a href="https://interestingengineering.com/innovation/two-time-crystals-quantum-ram"  target="_blank"  rel="dofollow">used in quantum computers</a>, magnetic sensors, high-power electric devices, radiation detectors, and lasers in the future, the <a href="https://www.eurekalert.org/news-releases/1042017"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">press release</a> added. </p>

<p>With its focus on nanosheet transistors and innovative backside power delivery, A16 paves the way for the production of 1.6nm chips by 2026.</p>


TSMC races for chip supremacy with new A16 process for AI-ready future


<p></p>



<p>Taiwan Semiconductor Manufacturing Company (TSMC), the leading flagbearer in chip manufacturing, has unveiled a new technology called A16. This unveil marks a significant step towards the production of its new ultra-advanced 1.6-nanometer (nm) chips by 2026. Although the naming sounds quite similar to Apple’s A16 processor found on the iPhone 15 series and iPhone 14 Pro, which itself is built by TSMC, this is not to be confused. </p>



<p>The announcement underscores TSMC&#8217;s commitment to maintaining its dominance in the chipmaking race, which will be powering the next generation of artificial intelligence (AI) advancements across mobile and personal devices, putting it against the likes of <a href="https://interestingengineering.com/innovation/nvidia-unveils-fastest-ai-chip"  target="_blank"  rel="dofollow">Nvidia</a>, Intel, and Samsung which are other players of the fabrication and AI chip industry.</p>



<h3 class="wp-block-heading" id="h-a16-nanosheet-transistors-with-backside-power-delivery">A16: Nanosheet transistors with backside power delivery</h3>



<p>During the North America Technology Symposium held in Santa Clara, California, TSMC <a href="https://pr.tsmc.com/english/news/3136"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">showcased</a> its A16 technology. This innovative process revolves around nanosheet transistors, a novel approach that promises &#8220;greatly improved logic density and performance&#8221; compared to existing technologies. Notably, A16 employs a revolutionary &#8220;backside power rail&#8221; system. </p>



<p>Unlike traditional chip designs where power flows from the top down, this method delivers power from the bottom. This innovative approach eliminates the need for intricate internal wiring, leading to significant improvements in energy efficiency.</p>



<h3 class="wp-block-heading" id="h-backside-power-delivery">Backside Power Delivery</h3>



<p>Interestingly, Intel preempted <a href="https://interestingengineering.com/innovation/sam-altman-plans-to-tap-tsmc-to-rival-nvidia-with-his-own-ai-chip"  target="_blank"  rel="dofollow">TSMC</a> in announcing the utilization of backside power delivery. Intel plans to integrate this technology into its 20A and 18A (2nm and 1.8nm) chipmaking processes as early as 2025. </p>



<p>The strategic move highlights the growing importance of efficiency in the ever-competitive chipmaking landscape. Intel has further bolstered its position by unveiling its 14A (1.4nm) technology earlier this year. Meanwhile, Samsung has set its sights on achieving mass production of 1.4nm chips by 2027.</p>



<h3 class="wp-block-heading" id="h-beyond-nanometers-the-rise-of-nanosheet-transistors">Beyond nanometers: The rise of nanosheet transistors</h3>



<p>Traditionally, the nanometer size on a chip has been directly linked to its performance and advancement. A smaller nanometer value indicated a denser packing of transistors, leading to significant performance gains. However, with the constant miniaturization of transistors, this approach has reached its physical limitations. Modern chipmaking necessitates not only a reduction in transistor size but also a complete restructuring of their design.&nbsp;</p>



<p>This is where nanosheet transistors come into play. Starting from the 2nm node, both TSMC and Intel have embraced the gate-all-around, or nanosheet, transistor structure. Samsung has already begun experimenting with this technology in its 3nm chips. Notably, Apple&#8217;s latest top-tier iPhone Pro utilizes TSMC&#8217;s 3nm technology, showcasing the increasing demand for advanced chips to power cutting-edge devices.</p>



<p>While the race for smaller transistors continues, the reality is that only a select few companies – TSMC, Intel, and Samsung – can afford the immense resources required to push the boundaries of chip production. Recognizing this, the U.S. government has awarded these three giants a collective $21.5 billion under the CHIPS Act. This initiative aims to incentivize the production of the most advanced chips within American borders.</p>



<h3 class="wp-block-heading">TSMC&#8217;s leading change</h3>



<p>As reported by <em>Nikkei Asia</em>, TSMC currently reigns supreme in the foundry service market, holding a staggering market share of nearly 60% according to Counterpoint, a technology market research firm. Samsung trails behind with a 13% share, followed by Taiwan&#8217;s UMC at 6%. Notably, Intel, traditionally focused on in-house chip production, has entered the foundry arena, aiming to become the number two player by 2030. This aggressive move further intensifies the competition within the chipmaking industry.</p>



<p>With its focus on nanosheet transistors and innovative backside power delivery, A16 paves the way for the production of 1.6nm chips by 2026. Surely, this advancement is crucial not only for maintaining global technological leadership but also for fueling the development of cutting-edge AI applications that will shape the future. As the competition intensifies, the collaboration between governments and leading chipmakers will be critical in ensuring a secure and sustainable future in this ever-evolving domain.</p>

<p>The green-eyed monster drone is 20 feet (6.1 meters) long and based on Textron&#8217;s highly successful M5 RIPSAW chassis.</p>


US tests bigger, meaner variant of Terminator-like robot drone tank

DARPA's RACER drone during its recent trials.


<p>DARPA has announced that its Robotic Autonomy in Complex Environments with Resiliency (RACER) program has passed another important milestone with testing its bigger, meaner drone variant. </p>



<p>A 12-ton beast of a machine, the larger RACER autonomous ground vehicle also has a pair of green lights reminiscent of glowing eyes.</p>



<p>The green-eyed monster drone is 20 feet (6.1 meters) long, skid-steer tracked, and based on Textron&#8217;s highly successful <a href="https://www.textronsystems.com/products/ripsaw-m5"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">M5 RIPSAW chassis</a>. The US Army already widely uses these for various logistical and tactical roles.</p>



<p>DARPA explains that the 12-ton RACER is being designed to complement and support other members of the RACER Fleet Vehicles (RFVs). However, its compatriots are much smaller, weighing 2 tons and measuring a paltry 11 feet (3.35 meters) long. </p>



<p>“Having two radically different types of vehicles helps us advance towards RACER’s goal of platform agnostic autonomy in complex, mission-relevant off-road environments significantly more unpredictable than on-road conditions,” explained Stuart Young, RACER program manager.</p>



<h3 class="wp-block-heading" id="h-racer-the-green-eyed-monster-drone">RACER: the green-eyed monster drone</h3>



<p>“For Phase 2, adding the combat-scale RHP robot supports porting and performance demonstration of RACER autonomy stacks at multiple scales concurrently while moving between highly varied terrains,&#8221; he added. </p>



<p>The larger RACER has been jointly developed by the University of Washington and NASA’s Jet Propulsion Laboratory. Its latest test, which appeared to have succeeded, occurred at a Texas-based range in late 2023. </p>



<p>The test involved two teams that had no prior experience in the testing area. This was by design to ensure the test was as realistic as possible for a real deployment.</p>



<figure class="wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

</div></figure>



<p>The goal was to see how these vehicles could perform in a foreign environment.</p>



<p>&#8220;Using fully unoccupied RFVs, RACER demonstrated autonomous movement within a 15-square-mile terrain area including highly diverse ground vegetation cover, trees, bushes, rocks, slopes, obstructed ditches, and creek crossings typical of the varied, complex Texas terrain familiar to armored maneuvers,&#8221; DARPA explained in its <a href="https://www.darpa.mil/news-events/2024-04-23"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">official press release</a>. </p>



<p>The tests also included nighttime operation, which DARPA explained revealed the new drone is equally as functional as in daylight hours.</p>



<h3 class="wp-block-heading" id="h-the-new-drone-operated-well">The new drone operated well</h3>



<p>In addition to an official press release on the test, DARPA has also released interesting footage of the 12-ton monster drone on the prowl. </p>



<p>Regarding the &#8220;green eyes,&#8221; these are simply status indicators showing that the vehicle is in autonomous mode, DARPA <a href="https://gizmodo.com/darpa-new-12-ton-robot-tank-glowing-green-eyes-vehicle-1851432307"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">explained to <em>Gizmodo</em></a>.</p>



<p>The RIPSAW M5, based on the new drone, is designed for silent operation and is currently used as part of the Army&#8217;s Robotic Combat Vehicle-Medium (RCV-M) program. They offer interesting opportunities for the Army, including protecting convoys and conducting rescue missions.</p>



<p>They can also be used for setting up perimeter defense, surveillance, patrolling the border, and crowd control. The RIPSAW can also be modified for the disposal of explosive devices. </p>



<p>DARPA has been trying to develop <a href="https://interestingengineering.com/military/defiant-to-start-sea-trials"  target="_blank"  rel="dofollow">autonomous</a> vehicles since the early 1980s, notably through something called the <a href="https://paleofuture.com/blog/2013/4/30/darpa-spent-1-billion-trying-to-build-a-real-life-skynet-in-the-1980s"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">Strategic Computing Initiative</a>. However, technology has come a long way since then, especially if the latest RACER tests are anything to go by.</p>

Anduril, General Atomics step closer to building wingmen drone for US

United States Air Force has selected Anduril and General Atomics selected as vendors to move forward on the Collaborative Combat Aircraft (CCA) program. 


<p>The US Air Force has announced the selection of drone maker General Atomics and defense startup Anduril to build and test the first batch of drone wingmen for the next part of the service’s Collaborative Combat Aircraft (CCA) program.</p>



<p>The selection was made from a pool of five competitors. The vendors out of the race are – Boeing, Lockheed Martin, and Northrop Grumman.</p>



<p>The Air Force also said that the companies not selected for the CCA program would still be a part of the “broader industry partner vendor pool”, which consists of more than 20 companies, and can compete for future efforts.</p>



<p>The five contractors were picked in the program’s first phase, which focused on design.</p>



<p>The Air Force has decided “to continue funding Anduril and General Atomics for detailed designs, manufacture, and testing of production representative test articles.”</p>

<p>The CCA program is part of the Next Generation Air Dominance Family of Systems, which is a DAF effort to equip the force with crewed and uncrewed platforms that can meet the pacing challenge.&nbsp;</p>



<p>It had been announced just over two years ago and “it&#8217;s truly encouraging to witness the rapid execution of this program,” said Frank Kendall, Secretary of the Air Force.</p>



<h3 class="wp-block-heading" id="h-air-force-s-expectations-with-cca-program">Air Force&#8217;s expectations with CCA program</h3>



<p>The announcement is huge as the program aims to create a&nbsp;series of drones using autonomous software&nbsp;to fly alongside piloted fighters, such as the F-35 and Next Generation Air Dominance system.</p>



<p>The Air Force <a href="https://www.af.mil/News/Article-Display/Article/3754980/air-force-exercises-two-collaborative-combat-aircraft-option-awards/"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">said</a> it is on track to make a “competitive production decision for the first increment of CCA in fiscal year 2026 and field a fully operational capability before the end of the decade.”</p>



<p>The program aims to deliver at least 1,000 drones, with a focus on cost-effective scalability.</p>



<p>Planning is also underway for CCA Increment 2 development, and initial activities are going to begin this year.</p>



<p>The <a href="https://interestingengineering.com/military/b52h-bombers-civilian-airfield-landing"  target="_blank"  rel="dofollow">Air Force</a> wants drones to be less expensive than piloted aircraft but still have the ability to carry out strikes, conduct reconnaissance, and also to have electronic warfare capabilities.</p>



<h3 class="wp-block-heading" id="h-anduril-and-general-atomics">Anduril and General Atomics</h3>



<p>In February 2024, GA-ASI successfully conducted the maiden flight of the XQ-67A CCA prototype aircraft, validating the “genus/species” concept pioneered by the Air Force Research Laboratory (AFRL) as part of the Low-Cost Attritable Aircraft Platform Sharing (LCAAPS) program.</p>



<p>General Atomics’ CCA production representative design is based upon the XQ-67A Off-Board Sensing Station developed for the AFRL.</p>



<p>To complement the CCA contract, General Atomics <a href="https://www.ga.com/ga-asi-selected-to-build-cca-for-aflcmc"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">said</a> it will continue to conduct a series of autonomy and mission system tests on the MQ-20 Avenger UAS and XQ-67A to accelerate the readiness of operational autonomy.</p>



<p>“The CCA program redefines the future of aviation and will shape the USAF acquisition model to deliver affordable combat mass to the warfighter at the speed of relevancy,” said Mike Atwood, Vice President of Advanced Programs for General Atomics &#8211; Aeronautical Systems, Inc. (GA-ASI).</p>



<p>Anduril also <a href="https://www.anduril.com/article/anduril-air-force-collaborative-combat-aircraft-CCA/"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">welcomed</a> the decision and said there is “no time to waste” as the success of the US and its allies in the future is dependent on the CCAs being “delivered at a speed, cost, and scale to beat the pacing threat.”</p>



<p>“Anduril is proud to pave the way for other non-traditional defense companies to compete and deliver on large scale programs,” said Brian Schimpf, Anduril CEO, and Co-Founder.</p>

<p>While all neutron stars boast powerful magnetic fields, magnetars stand out with fields exceeding 10,000 times that of a typical neutron star.</p>


Scientists detect first massive extragalactic magnetar flare in nearby galaxy


<p></p>



<p>On November 15th, 2023, a fleeting phenomenon unfolded in the vast expanse of our space. The European Space Agency&#8217;s (ESA) INTEGRAL satellite, tasked with observing <a href="https://interestingengineering.com/space/brightest-gamma-ray-burst-supernova"  target="_blank"  rel="dofollow">gamma-ray emissions</a>, detected a brief, powerful burst originating from the nearby galaxy M82, roughly 12 million light-years away. This singular event, lasting a mere tenth of a second, sparked a scientific investigation that culminated in a groundbreaking discovery: the first confirmed extragalactic flare from a magnetar.</p>



<h3 class="wp-block-heading" id="h-rapid-response-unveils-a-rare-phenomenon">Rapid response unveils a rare phenomenon</h3>



<p>The sudden nature of the gamma-ray burst presented a unique challenge. Fortunately, INTEGRAL&#8217;s data analysis system, hosted at the University of Geneva (UNIGE), reacted swiftly. &#8220;Only 13 seconds after detection, a gamma-ray burst alert was sent to astronomers worldwide,&#8221; explains Dr. Carlo Ferrigno, co-author of the study and a senior researcher at UNIGE. This rapid response system, developed by UNIGE scientists, played a crucial role in pinpointing the source of the burst within the M82 galaxy.</p>



<p>The location of the event immediately piqued the interest of astronomers. &#8220;Gamma-ray bursts typically originate from distant corners of the cosmos,&#8221; explains Dr. Sandro Mereghetti, lead author of the study published in <em><a href="https://www.nature.com/articles/s41586-024-07285-4"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">Nature</a></em>, &#8220;but this one came from a bright, nearby galaxy.&#8221; This unusual origin prompted the team to seek follow-up observations.</p>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1920" height="1439" src="https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_ef85af.png?w=1441" alt="" class="wp-image-61097" srcset="https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_ef85af.png 1920w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_ef85af.png?resize=300,225 300w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_ef85af.png?resize=768,576 768w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_ef85af.png?resize=1441,1080 1441w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/image_ef85af.png?resize=1536,1151 1536w" sizes="(max-width: 1920px) 100vw, 1920px" /><figcaption class="wp-element-caption"><em>No afterglow in X-rays and visible light from a giant magnetar flare</em>. <em><a href="https://www.esa.int/ESA_Multimedia/Images/2024/04/No_afterglow_in_X-rays_and_visible_light_from_a_giant_magnetar_flare"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">Credits: ESA</a></em></figcaption></figure>



<h3 class="wp-block-heading">The search for the elusive afterglow</h3>



<p>Following standard protocol for short gamma-ray bursts, the team quickly enlisted ESA&#8217;s XMM-Newton X-ray space telescope to observe the location of the event. This urgency stemmed from the possibility of detecting an afterglow in X-rays or visible light, a signature often associated with the violent collision of neutron stars, a potential source for the burst.</p>



<p>However, XMM-Newton&#8217;s observations yielded no such afterglow. Ground-based telescopes, including the Italian Telescopio Nazionale Galileo and the French Observatoire de Haute-Provence, also failed to detect any signal in visible light. Additionally, gravitational wave detectors like LIGO, VIRGO, and KAGRA found no corresponding signal.</p>



<p>The absence of these secondary effects, coupled with the location and short duration of the burst, pointed towards a single compelling explanation: a colossal flare from a magnetar.</p>



<h3 class="wp-block-heading">Magnetars: Universe&#8217;s mega-magnetic monsters</h3>



<p><a href="https://interestingengineering.com/science/nasa-finds-new-clues-about-mysterious-fast-radio-burst-from-magnetar"  target="_blank"  rel="dofollow">Magnetars</a> are a rare breed of neutron stars, the incredibly dense remnants of massive stellar explosions. While all neutron stars boast powerful magnetic fields, magnetars stand out with fields exceeding 10,000 times that of a typical neutron star. This extreme magnetism fuels their outbursts, releasing bursts of immense energy.</p>



<p>&#8220;These flares are incredibly powerful,&#8221; explains Dr. Volodymyr Savchenko, co-author of the study and a senior researcher at UNIGE. He cites the December 2004 magnetar flare, which, despite originating 30,000 light-years away, still impacted Earth&#8217;s upper atmosphere, mimicking the effects of a much closer solar flare.</p>



<h3 class="wp-block-heading">A discovery with far-reaching implications</h3>



<p>The detection of this magnetar flare in M82 marks a watershed moment in our understanding of these enigmatic stellar objects.&nbsp; &#8220;This find supports the notion that magnetars are likely young neutron stars,&#8221; highlights Dr. Savchenko. The vibrant star-forming environment within M82 further reinforces this connection.</p>



<p>This discovery has opened a new chapter in the study of magnetars. Astronomers now aim to expand their search to other star-forming regions beyond our Milky Way, with the ultimate goal of comprehending the frequency of these colossal flares and the role they play in the energy dynamics of neutron stars.</p>



<h3 class="wp-block-heading">INTEGRAL: A key instrument for cosmic science</h3>



<p>The fleeting nature of such events underscores the importance of instruments like INTEGRAL. Its wide field of view, vastly exceeding that of the full moon, allows it to capture these massive occurrences.  &#8220;Our rapid data processing system is instrumental in alerting the scientific community in real-time,&#8221; emphasizes Dr. Ferrigno. Additionally, the flexibility afforded by ESA&#8217;s observing schedule proves critical for time-sensitive discoveries like this one. In this instance, a delay of merely a day could have significantly hampered scientists&#8217; ability to identify the burst&#8217;s source.</p>

ETH Zurich&#8217;s wheeled-legged robot masters urban terrain autonomously

ETH's Zurich ANYmal robot undergoing testing. 


<p>ETH Zurich researchers have developed a locomotor control that can enable wheeled-legged robots to autonomously navigate various urban environments.</p>



<p>The robot was equipped with sophisticated navigational abilities thanks to a combination of machine learning algorithms. It was tested in the cities of Seville, Spain, and Zurich, Switzerland.</p>



<p>With little assistance from humans, the team&#8217;s <a href="https://interestingengineering.com/innovation/anymal-robot-tackles-tricky-terrains-powered-by-eth-zurichs-new-system"  target="_blank"  rel="dofollow">ANYmal</a> wheeled-legged robot accomplished autonomous operations in urban settings at the kilometer scale. </p>



<p>It made its way past a variety of obstacles, including pedestrians, uneven steps, stairs, and natural terrain.</p>



<p>The team claims the autonomous navigation system helped the robot navigate new areas, recall previous locations to assist in making decisions in real-time, and respond quickly to changing circumstances, such as pedestrian obstructions.</p>

<h3 class="wp-block-heading" id="h-robust-urban-navigation-achieved">Robust urban navigation achieved</h3>



<p>The <a href="https://interestingengineering.com/innovation/experts-crafts-waterproof-low-voltage-artificial-muscles-for-bot-motion"  target="_blank"  rel="dofollow">ETH Zurich</a> team engineered a sophisticated autonomous navigation system for wheeled-legged <a href="https://interestingengineering.com/lists/top-7-robotics-stories-of-2023-interesting-engineering"  target="_blank"  rel="dofollow">robots</a>, seamlessly integrating navigation and locomotion controls. </p>



<p>Its method combined hybrid locomotion control, developed through model-free reinforcement learning (RL) and privileged learning, with a navigation controller optimized via hierarchical RL (HRL).</p>



<p>According to the team, the training involved simulated data, with controllers then integrated into a global navigation system using digital-twin models and high-resolution laser scans for experiment planning and onboard localization.</p>



<p>&#8220;Current work on wheel-legged platforms has gone beyond bioinspiration, but simultaneously opens new questions on how inspiration from animals can further improve human-made systems,&#8221; said Krzysztof Walas from Politechnika Poznanska in a statement.</p>



<p>According to researchers, its controllers facilitated adaptive gait selection, efficient terrain negotiation, and responsive navigation, adeptly avoiding static and dynamic obstacles. </p>



<p>Practical assessments highlighted the potential of wheeled-legged robots for achieving efficient and robust autonomy in real-world scenarios. </p>



<p>The claims that additional comparative studies also affirm the superiority of its tightly integrated navigation controller over traditional systems.</p>



<h3 class="wp-block-heading" id="h-advanced-autonomous-mobility">Advanced autonomous mobility</h3>



<p>The autonomous navigation system for wheeled-legged robots integrates multiple payloads for localization, terrain mapping, and safety, including LIDAR sensors, a stereo camera, a delivery box, a 5G router, and a GPS antenna.</p>



<p>The stereo camera, equipped with high-frequency object detection, enables real-time tracking of people within a 20-meter range, enhancing safety.</p>



<p>To address dynamic obstacles, the team buffers the elevation map around detected human positions. </p>



<p>The navigation system employs a hierarchical approach, extracting waypoints from a global navigation path. It also uses a pure-pursuit-inspired algorithm for waypoint tracking.</p>



<p>The low-level controller (LLC), commanded by a high-level controller (HLC), guides the robot along intermediate waypoints. </p>



<p>Both controllers are neural networks trained via reinforcement learning (RL), with the HLC representing a novel contribution. This helps to integrate local navigation planning and path-following control.</p>



<p>The locomotion controller (LLC), based on recurrent neural networks (RNNs), autonomously selects gaits and transitions between walking and driving modes. It is trained using privileged learning in simulation environments.</p>



<p>The team&#8217;s training environment, inspired by navigation graphs from computer games, provides diverse challenges such as detours, dynamic obstacles, and rough terrains. </p>



<p>Kilometer-scale autonomous deployments in the urban environments of Zurich and Seville demonstrate the system&#8217;s capability, covering (5.15 miles or 8.29 kilometers) in Zurich with minimal human intervention.</p>



<p>A handheld laser scanner captures dense point clouds of the area, which are georeferenced and converted into a mesh representation for creating a navigation graph. </p>



<p>The robot localizes itself using onboard sensors and navigates toward goal points autonomously, with paths converted into robot-relative coordinates for navigation policy guidance.</p>



<p>Researchers claim that multiple long-distance experiments validate the system&#8217;s robustness. The experiments required navigation through diverse obstacles to reach distant goal points manually selected to maximize coverage.</p>



<p>The system showcases advanced autonomy and adaptability in complex urban environments, offering promising applications in various real-world scenarios.</p>



<p>The details of the team&#8217;s <a href="https://dx.doi.org/10.1126/scirobotics.adi9641"  rel="noopener noreferrer nofollow" target="_blank">research</a> were published in the journal <em>Science Robotics</em> on April 24.</p>

US President Joe Biden signs TikTok ban bill into law

President Joe Biden signed into law the divestiture of TikTok from its Chinese parent company ByteDance or face a national ban.


<p>Hammering the final nail in the coffin, US President Joe Biden signed a bill that includes the ban on the popular social media platform <a href="https://interestingengineering.com/culture/tiktok-beat-google-to-become-the-most-visited-site-of-2021"  target="_blank"  rel="dofollow">TikTok</a> in the country.</p>



<p>The signature comes after the US Senate approved the Protecting Americans from Foreign Adversary Controlled Applications Act with a 79-18 majority on April 23. With the recent development, TikTok, the popular short-video-sharing application with over 170 million users, now faces a nationwide ban in the US.</p>



<p>The ban arrives amidst warnings from agencies such as the FBI, cautioning that TikTok&#8217;s Chinese owner ByteDance could potentially share users&#8217; sensitive data with China&#8217;s authoritarian government. </p>



<p>Despite these concerns, ByteDance consistently asserts that it has never engaged in such actions and would not comply if requested to do so. </p>



<h3 class="wp-block-heading" id="h-requirement-to-divest-chinese-ownership">Requirement to divest Chinese ownership</h3>



<p>The stage was set as the law <a href="https://interestingengineering.com/culture/tiktok-divest-or-ban-bill"  target="_blank"  rel="dofollow">first got approval</a> in the House of Representatives on April 20. The law mandated a national prohibition of TikTok in the event that its Chinese proprietor, ByteDance, declines to sell the platform.</p>



<p>In favor of a revised divestment or ban bill against TikTok, the House voted 360 to 58. ByteDance will have nine months, with a three-month extension, to find a US buyer for the video-sharing application. That would mean that TikTok could face a complete ban by January 2025. </p>



<p>“This bill protects Americans and especially America’s children from the malign influence of Chinese propaganda on the app TikTok. This app is a spy balloon in Americans’ phones,” said Michael McCaul, a Texas Republican and author of the bill, reported&nbsp;<a href="https://www.bloomberg.com/news/articles/2024-04-20/tiktok-divest-or-ban-bill-expected-to-become-us-law-within-days?utm_source=google&amp;utm_medium=bd&amp;cmpId=google"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank"><em>Bloomberg</em></a>.</p>



<p>The company is likely to challenge the bill in court, which may extend the deadline set by the US lawmakers. </p>



<h3 class="wp-block-heading" id="h-claims-of-selective-targeting">Claims of selective targeting</h3>



<p>The company has claimed that TikTok is an independent platform, with its own leadership team, including a CEO based in Singapore, a COO based in the US and a global head of trust and safety based in Ireland.</p>



<p>In a statement, TikTok claimed that it&#8217;s &#8220;unfortunate&#8221; the US is &#8220;using the cover of important foreign and humanitarian assistance to once again jam through a ban bill that would trample the free speech rights of 170 million Americans, devastate 7 million businesses, and shutter a platform that contributes $24 billion to the U.S. economy, annually.&#8221;</p>



<p>The developers claim that by focusing only on TikTok, the US government is acting hypocritically. They draw attention to the fact that the government gives other tech giants like Google and Meta, which are also inspected for data safety, a free ride.</p>



<p>The ban comes as a <a href="https://interestingengineering.com/culture/tiktok-ban-would-kill-businesses"  target="_blank"  rel="dofollow">significant setback</a> those who create content and small businesses that rely on TikTok for revenue. Experts worry that if the app is taken down, their wages and jobs will collapse. Even the creators claim that their right to free speech is violated by the new law.</p>



<p>&#8220;We will not stop fighting and advocating for you. We will continue to do all we can, including exercising our legal rights, to protect this amazing platform that we have built with you,” said TikTok’s chief Shou Zi Chew last month after the House passed an order against the platform.</p>

<p>MIT CSAIL conducted virtual training programs  at five facilities for prisoners to improve their self-efficacy and digital literacy.</p>


Brave behind bars: MIT program empowers inmates with computer skills

The Stata Center, an architectural masterpiece, which houses MIT's CSAIL. 


<p>Researchers at the Massachusetts Institute of Technology&#8217;s (MIT) Computer Science &amp; Artificial Intelligence Laboratory (CSAIL) conducted a 12-week college-accredited web design class for inmates of five correctional facilities in the US. The training program, which was conducted virtually, aimed to improve the inmates&#8217; self-efficacy and digital literacy.</p>



<p>The US has the highest incarceration rate in the world, with an estimated 0.7 percent of its population in prison. While the rest of the population reaps the benefits of broadband internet, <a href="https://interestingengineering.com/culture/us-prisons-creating-massive-database-of-prisoners-voices"  target="_blank"  rel="dofollow">inmates of correctional facilities</a> are denied access to basic internet, a United Nations&#8217; declared human right.&nbsp;</p>



<p>Researchers suggest that denial of the internet and digital tools effectively serves as a second punishment for prisoners serving their sentences, leading to their incapacitation and social exclusion post-release. As the world moves technologically forward, the lack of digital skills also impedes access to social services available to formerly incarcerated people.&nbsp;</p>



<p>Studies have shown that academic accomplishments during prison time improve inmate self-efficacy, increase the likelihood of finding employment post-release, and reduce the chances of returning to prison. Therefore, researchers at MIT CSAIL conducted 12-week courses to improve digital literacy among inmates, dubbed Brave Behind Bars.&nbsp;</p>



<h3 class="wp-block-heading">Details of the program&nbsp;</h3>



<p>The program was accredited by three renowned educational institutes in the US &#8211;&nbsp;Georgetown University, Benjamin Franklin Institute of Technology, and Washington County Community College &#8211; and conducted synchronously via Zoom across five correctional institutes in the US. Over two years, the MIT CSAIL team trained 102 students.&nbsp;</p>



<p>The course curriculum included six weeks of the basics of HTML, CSS, and Javascript taught in two-hour classes twice a week. Each class consisted of a 30-minute lecture followed by 90 minutes of a breakout session with a teaching assistant.&nbsp;</p>



<p>The teaching assistants included a mix of computer science graduates from MIT CSAIL and formerly incarcerated graduates, who also helped align the course to students&#8217; needs. In the breakout sessions, each TA helped 2 to 4 students implement the code and debug any issues they faced.&nbsp;</p>



<p>In the following six weeks, each student worked on a project using their skills to design a website on a social issue that impacted their community. A sample of this is shown below.&nbsp;</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1920" height="1080" src="https://cms.interestingengineering.com/wp-content/uploads/2024/04/Samples.jpg" alt="" class="wp-image-60846" srcset="https://cms.interestingengineering.com/wp-content/uploads/2024/04/Samples.jpg 1920w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/Samples.jpg?resize=300,169 300w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/Samples.jpg?resize=768,432 768w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/Samples.jpg?resize=1536,864 1536w" sizes="(max-width: 1920px) 100vw, 1920px" /><figcaption class="wp-element-caption">A sample of six websites designed by prison inmates at various correctional facilities in the US, after being virtually trained by MIT CSAIL.

<h3 class="wp-block-heading" id="h-impact-of-the-program">Impact of the program</h3>



<p>Through surveys conducted before and after the course, the participants reported increased self-confidence after <a href="https://interestingengineering.com/culture/finnish-startup-turns-to-cheap-prison-labor-to-train-its-ai"  target="_blank"  rel="dofollow">learning a new skill</a>. Since students came from various backgrounds, the learning experience differed for each.&nbsp;</p>



<p>A female student who had not previously interacted much with the opposite gender in the almost 22 years of her incarceration found that the mixed-gender classes helped her confidence in interacting with the opposite sex as well.&nbsp;</p>



<p>For others, the teaching curriculum was a &#8220;welcoming learning environment&#8221; with a &#8220;non-judgemental inclusive atmosphere.&#8221; Breakout rooms were a huge hit, and they provided students with the help they needed to understand concepts and solve the obstacles they faced.&nbsp;</p>



<p>The program also achieved a few firsts during its two-year period. It was the first mixed-gender course undertaken at a correctional facility in the US. One of the facilities required providing an internet connection to the inmates for the first time in its history, which they plan to continue in the future, too.&nbsp;</p>



<p>While a lot of research is focused on technological biases that lead to the incarceration of individuals from marginalized and minority communities in the US, this study focuses on interventions that enable successful reentry for those who have finished their sentences.&nbsp;</p>



<p>The research findings will be presented at the <em>CHI Conference</em> <em>on Human Factors in Computing Systems</em>, to be held in Honolulu next month.</p>

<p>Mojave was equipped with two of Dillon’s DAP-6 Gun Pod Systems for the artillery tests. </p>


In a first, minigun-wielding Mojave drone pounds 6,000 rounds a minute

GA-ASI's Mojave drone equipped with pair of DAP-6 gun pods and various missiles under its wings.


<p>General Atomics Aeronautical Systems Inc. (GA-ASI) has successfully tested the <a href="https://interestingengineering.com/culture/general-atomics-unveils-its-mojave-drone-that-can-carry-16-hellfire-missiles"  target="_blank"  rel="dofollow">Mojave drone</a> to demonstrate its utility in combat. </p>



<p>On April 13, 2024, the unmanned aircraft system (UAS) destroyed static targets during live-fire testing, marking another achievement for the demonstrator aircraft.</p>



<p>In a video released by the firm, the drone is seen lighting up a Chevrolet truck, its target, in seconds. The live-fire demonstration, funded by GA-ASI&#8217;s internal research and development budget, occurred at Yuma Proving Ground in Arizona.</p>



<p>Unveiled in 2021, Mojave is a new offering from the UAS&#8217;s Predator series family. It is being pitched as an ideal equipment for armed overwatch, attack, and reconnaissance missions.</p>



<p>In August 2023, GA-ASI successfully tested the Mojave <a href="https://interestingengineering.com/innovation/general-atomics-mojave-can-now-takeoff-and-land-on-dirt"  target="_blank"  rel="dofollow">drone on a dirt strip</a> to widen its range of operations. The test demonstrated Mojave&#8217;s ability to complete short takeoffs in as little as 586 feet and short landings in 335 feet.</p>

<h3 class="wp-block-heading" id="h-a-capable-proposition"><strong>A capable proposition</strong></h3>



<p>GA-ASI collaborated with Dillon Aero to equip the Mojave aircraft with two of Dillon’s DAP-6 Gun Pod Systems for the artillery tests. </p>



<p>In the demonstration, Mojave conducted seven passes over two flights, firing approximately 10,000 rounds of ammunition as it effectively engaged and destroyed a range of targets.</p>



<p>&#8220;Seeing our Mojave perform this live-fire demo really emphasizes the versatility of the Mojave UAS and what it can do,&#8221; said David R Alexander, president of GA-ASI, in a <a href="https://www.ga-asi.com/ga-asi-mojave-lights-up-the-yuma-desert-in-live-fire-demonstration"  rel="noopener noreferrer nofollow" target="_blank">statement</a>.</p>



<p>&#8220;Mojave has the ability to act as a sensor, shooter, and sustainer while mitigating threat environments and vulnerabilities and safeguarding human lives.&#8221; </p>



<p>According to <a href="https://www.twz.com/air/minigun-armed-mojave-drone-now-blasting-targets-at-6000-rounds-per-minute"  rel="noopener noreferrer nofollow" target="_blank">The War Zone</a> (TWZ), the Minigun in a DAP-6 pod fires at 3,000 rounds per minute. With two pods on Mojave, the combined rate is 6,000 rounds per minute. A DAP-6&#8217;s max magazine holds 3,000 rounds, giving it 60 seconds of firing time. It can be loaded with less ammo to reduce weight. An empty DAP-6 weighs 162 lbs (73.5 kg), growing to around 350 lbs (158.8 kg) when fully loaded.</p>

</div></figure>



<p>The military and aerospace communities have shown great interest in Mojave due to its short takeoff and landing (STOL) capabilities. Mojave can perform STOL while &#8220;retaining significant advantages in endurance and persistence over Vertical Takeoff and Landing (VTOL) and human-crewed aircraft,” said Alexander, president of GA-ASI, in a blog&nbsp;<a href="https://www.ga-asi.com/ga-asi-mojave-stol-uas-completes-first-dirt-operation"  target="_blank"  rel="noopener noreferrer nofollow" target="_blank">post</a> earlier. </p>



<p>According to GA-ASI, Mojave is a special kind of <a href="https://interestingengineering.com/innovation/technology-enables-drones-to-autonomously-navigate"  target="_blank"  rel="dofollow">UAS</a> as it allows for operations in areas once considered unsuitable for such drones. </p>



<h3 class="wp-block-heading"><strong>An evolution of GA-ASI&#8217;s UAS technology</strong></h3>



<p>The company launched the MQ-1 Predator drone 25 years ago, and since then, it has released more advanced models, including the MQ-9 Reaper and MQ1C-Gray Eagle. Its drone fleet claims to have operated for over 7 million hours, most of which were spent in battle.</p>



<p>Mojave, designed according to Modular Open System Approach (MOSA) principles, incorporates GA-ASI’s Grey Eagle 25M program&#8217;s updated avionics, data connections, sensor fusion, and laptop-based ground control station. </p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1920" height="1080" src="https://cms.interestingengineering.com/wp-content/uploads/2024/04/Untitled-design-2024-04-24T172219.084.jpg" alt="The Mojave drone undergoing testing at Yuma Proving Ground in Arizona." class="wp-image-60860" srcset="https://cms.interestingengineering.com/wp-content/uploads/2024/04/Untitled-design-2024-04-24T172219.084.jpg 1920w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/Untitled-design-2024-04-24T172219.084.jpg?resize=300,169 300w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/Untitled-design-2024-04-24T172219.084.jpg?resize=768,432 768w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/Untitled-design-2024-04-24T172219.084.jpg?resize=1536,864 1536w" sizes="(max-width: 1920px) 100vw, 1920px" /><figcaption class="wp-element-caption">The Mojave drone undergoing testing at Yuma Proving Ground in Arizona.</figcaption></figure>



<p>Additionally, Mojave boasts larger wings equipped with high-lift devices, a battle-tested 450-HP turbine engine, and robust landing gear, rendering it well-suited for operations in semi-improved environments with minimal ground support.</p>



<p>Mojave can land, re-arm, and take off from harsh locations near non-permissive environments with speed and carry twice as much cargo as aircraft from previous models. </p>



<p>According to GA-ASI, owing to its larger wing area, it can carry up to 16 AGM-114 Hellfire or comparable missiles at 3,600 lbs (1,633 kg). Mojave can also be outfitted with an array of sensors, such as EO/IR, SIGINT, and Synthetic Aperture Radar/Ground Moving Target Indicator (SAR/GMTI), to facilitate land or marine missions.</p>



<p>According to TWZ, the completion of the tests comes as the firm is looking to pitch a hybrid model that combines features of Mojave with the MQ-1C Gray Eagle to the US Army. This proposed platform aims to serve as a new armed reconnaissance solution, especially after the recent cancellation of the Army&#8217;s armed scout helicopter program.</p>

<p>The US space agency is looking for industry partners to deploy its Hall-effect thruster technology in space.</p>


NASA’s new Hall-effect thruster could unlock small spacecraft revolution


<p></p>



<p>NASA has revealed an all-new electric propulsion system for small spacecraft.</p>



<p>The new propulsion system, the NASA-H71M sub-kilowatt Hall-effect thruster, will be used for planetary exploration as well as for increasing the lifespan of existing satellites.</p>



<p>The system is part of NASA’s broader plan to commercialize specific technologies. By allowing private industry partners to test and develop the technology, they could eventually rely on those partners for future missions.</p>



<p>Northrop Grumman subsidiary SpaceLogistics will soon put the technology to the test via its NGHT-1X Hall-effect thruster.</p>



<h3 class="wp-block-heading" id="h-nasa-s-new-hall-effect-thruster">NASA’s new Hall-effect thruster</h3>



<p>A Hall-effect thruster is a type of ion thruster that accelerates propellant using an electric field. The technology is already widely used in satellites in low Earth orbit.</p>



<p>NASA’s H71M sub-kilowatt Hall-effect thruster takes the technology to the next level. It is well-suited to long-duration missions and was designed to enable small spacecraft to reach escape velocity as well as capture orbits.&nbsp;</p>



<p>As such, it could form a crucial part of NASA’s future plans to explore our solar system, the US space agency explained on its website.</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1000" height="474" src="https://cms.interestingengineering.com/wp-content/uploads/2024/04/hall-1.jpg" alt="" class="wp-image-60969" srcset="https://cms.interestingengineering.com/wp-content/uploads/2024/04/hall-1.jpg 1000w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/hall-1.jpg?resize=300,142 300w, https://cms.interestingengineering.com/wp-content/uploads/2024/04/hall-1.jpg?resize=768,364 768w" sizes="(max-width: 1000px) 100vw, 1000px" /><figcaption class="wp-element-caption">The NASA-H71M Hall-effect thruster on the Glenn Research Center Vacuum Facility 8 thrust stand.

<p>Scientists at NASA’s Glenn Research Center engineered the propulsion system to operate efficiently on low power (sub-kilowatt) while having a high-propellant throughput, meaning that the system can use a high total mass of propellant over its lifetime.</p>



<p>This is crucial for the types of maneuvers required in deep space missions. Most commercial spacecraft today don’t have the capacity to travel from low Earth orbit to the moon or Mars. They typically require a helping hand from the launch vehicle that fires them into space.</p>



<p>NASA’s technology would enable this type of mission flexibility, meaning future missions could take on a whole host of new scientific objectives. In fact, the technology will soon be used by SpaceLogistics, a Northrop Grumman subsidiary. </p>



<p>The company aims to use the technology in its Mission Extension Pod, which will increase satellite lifespans by adjusting their trajectory in geosynchronous Earth orbit. SpaceLogistics will use the NGHT-1X Hall-effect thruster, which is based on the NASA-H71M.&nbsp;</p>



<h3 class="wp-block-heading" id="h-exploring-the-solar-system">Exploring the solar system</h3>



<p>The technology’s state-of-the-art capabilities also means spacecraft will be able to enter orbits around distant moons and planets. Once there, they would also be able to alter their own orbits, which would be a massive improvement over previous missions with brief flyby periods.</p>



<p>Hall-effect thrusters are already widely used in today’s satellites. They are efficient for orbital adjustment maneuvers as well as increasingly necessary <a href="https://interestingengineering.com/science/russian-debris-almost-destroys-nasa-satellite"  rel="dofollow">collision avoidance</a> maneuvers. </p>



<p>However, according to <a href="https://science.nasa.gov/science-research/science-enabling-technology/pushing-the-limits-of-sub-kilowatt-electric-propulsion-technology-to-enable-planetary-exploration-and-commercial-mission-concepts/"  rel="noopener noreferrer nofollow" target="_blank">NASA’s post</a>, its design extends operational lifetimes, offering over 15,000 hours of operation.</p>



<p>NASA’s work with its H71M sub-kilowatt Hall-effect thruster technology will help it continue to build its vast network of private sector partners. In recent years, it has leveraged this strategy for some of its most ambitious missions, including the <a href="https://interestingengineering.com/lists/artemis-iii-historic-2026-lunar-landing"  rel="dofollow">Artemis</a> moon missions.</p>

<p>The Freeman Lab developed cells with functional cytoskeletons using a novel approach that bypasses natural proteins.</p>


Researchers create first artificial, modifiable cells with programmable DNA

Synthetic cells created by UNC-Chapel Hill researchers


<p>Researchers at University of North Carolina-Chapel Hill have successfully engineered functional artificial cells in the lab which behave like living cells.</p>



<p>Ronit Freeman and her team have revealed their success in manipulating DNA and proteins, which are fundamental components of life, to engineer artificial cells that closely resemble those found in the human body. </p>



<p>As per Freeman, the synthetic cells were stable even at 122<strong>°</strong> Fahrenheit (50° Celsius). This opens up the &#8220;possibility of manufacturing cells with extraordinary capabilities in environments normally unsuitable to human life.”</p>



<p>Instead of creating materials that are made to last, Freeman says their materials are made to task — perform a specific function and then modify themselves to serve a new function. </p>



<p>This achievement holds significant promise for advancements in regenerative medicine, drug delivery methods, and diagnostic technologies.</p>



<p>&#8220;With this discovery, we can think of engineering fabrics or tissues that can be sensitive to changes in their environment and behave in dynamic ways,&#8221; states Freeman.</p>



<h3 class="wp-block-heading" id="h-generating-artificial-cells">Generating artificial cells</h3>



<p>Cells and tissues rely on proteins to carry out various tasks and construct vital structures. One such structure, the cytoskeleton, serves as the framework of a cell, enabling it to function properly. </p>



<p>The cytoskeleton is crucial for maintaining cell shape and facilitating responses to the surrounding environment.</p>



<p>The team developed artificial cells with functional cytoskeletons using a novel approach that bypasses natural proteins. They developed a cutting-edge technology called programmable peptide-DNA technology. </p>



<p>This method orchestrates a collaboration between peptides, the basic building blocks of proteins, and repurposed genetic material to construct a cytoskeleton.</p>



<p>As a result, these engineered cells can adapt their shape and respond to environmental cues, showcasing the remarkable potential of synthetic biology.</p>



<h3 class="wp-block-heading" id="h-possible-practical-applications">Possible practical applications</h3>



<p>&#8220;DNA does not normally appear in a cytoskeleton. We reprogrammed sequences of DNA so that it acts as an architectural material, binding the peptides together,&#8221; Freeman said. &#8220;Once this programmed material was placed in a droplet of water, the structures took shape.&#8221;</p>



<p>This never-before-seen capability to program DNA empowers scientists to design cells tailored for specific purposes and even regulate how these cells respond to external stresses. </p>



<p>While synthetic cells crafted by the Freeman Lab lack the complexity of living cells, they offer a level of predictability and resilience to harsh conditions such as extreme temperatures.</p>



<p>Rather than focusing on creating enduring materials, Freeman emphasizes the adaptability of these cells—they are engineered to perform specific functions and then adapt to new tasks. </p>



<p>By incorporating different peptide or DNA designs, these materials can be customized to program cells within fabrics or tissues. This versatility opens up possibilities for integration with other synthetic cell technologies, potentially revolutionizing fields like biotechnology and medicine.</p>
