Droplets with coronaviruses last longer than previously thought

It is easier to get infected in winter than in summer - this is true for the Corona pandemic, for influenza and for other viral diseases. Relative humidity plays an important role in this. Outdoors, it is much higher outside in winter than in summer, as can be seen from the fact that our breath condenses into droplets in the cold air.

WildSpot AR: Augmented Reality Citizen Science Game Is Coming to the National Parks

An augmented reality game, WildSpot AR and the National Park Science Challenge invite you to visit urban National Parks and explore science. Gluttonous space tourists from another dimension are creating portals into our world, with the aim of turning Earth into a popular alien theme park, and the InterDimensional Council, or IDC, needs Earth-based citizen scientists to stop them!

New nano particles suppress resistance to cancer immunotherapy

A specially designed lipid nanoparticle could deliver immune-signaling molecules into liver macrophage cells to overcome resistance to anti-tumor immunotherapy. Hokkaido University scientists and colleagues in Japan have found a way that could help some patients overcome resistance to an immunotherapy treatment for cancer. The approach, proven in mice experiments, was reported in the Journal for Immunotherapy of Cancer.

Child’s play: are Tibetan hand and foot traces the earliest example of parietal art?

Fossilised footprints, and more rarely, handprints, can be found around the world left as people went about their daily business, preserved by freak acts of geological preservation. In new research [] an international team describe ancient hand and footprints made deliberately which they argue represent art. Hand shapes are commonly...

Infants exposed to domestic violence have poorer cognitive development

COLUMBIA, Mo. – While assessing a pregnant woman with premature labor in 1983, Linda Bullock noticed bruises on the woman. When she asked what happened, the woman told Bullock a refrigerator had fallen on her while cleaning the kitchen. “Something didn’t seem right, but I didn’t know what to say...

Chemical discovery gets reluctant seeds to sprout

Seeds that would otherwise lie dormant will spring to life with the aid of a new chemical discovered by a UC Riverside-led team. Plants have the ability to perceive drought. When they do, they emit a hormone that helps them hold on to water. This same hormone, ABA, sends a message to seeds that it isn’t a good time to germinate, leading to lower crop yields and less food in places where it’s hot — an increasingly long list as a result of climate change.

COVID-19 is evolving to get better at becoming airborne, new study shows

Results of a new study led by the University of Maryland School of Public Health show that people infected with the virus that causes COVID-19 exhale infectious virus in their breath – and those infected with the Alpha variant (the dominant strain circulating at the time this study was conducted) put 43 to 100 times more virus into the air than people infected with the original strains of the virus. The researchers also found that loose-fitting cloth and surgical masks reduced the amount of virus that gets into the air around infected people by about half. The study was published in Clinical Infectious Diseases.

New engine design could muffle roar of fighter jets

Aerospace engineers at the University of Cincinnati have come up with a new nozzle design for F-18 fighter planes to dampen the deafening roar of the engines without hindering performance. Distinguished professor Ephraim Gutmark, an Ohio Eminent Scholar, and his students in UC’s College of Engineering and Applied Science designed...

Registration opens: IOP Publishing’s free-to-attend Environmental Research 2021 conference

Scientists, academics and policymakers dedicated to tackling environmental threats can now register to attend IOP Publishing’s (IOPP) Environmental Research 2021 conference. Taking place virtually between 15 and 19 November, participants will connect with leading experts to debate the direction and effectiveness of the latest environmental scientific research and work together to inspire global action.

New cell type in human skin discovered to contribute to inflammatory skin diseases like atopic dermatitis and psoriasis

Agency for Science, Technology and Research (A*STAR), Singapore. A team of international scientists and clinical experts have unravelled a new cell type in human skin that contributes to inflammatory skin diseases such as atopic dermatitis (AD) and psoriasis (PSO). Their study findings were published in the Journal of Experimental Medicine in September 2021. The team hails from A*STAR’s Singapore Immunology Network (SIgN), in collaboration with the Skin Research Institute of Singapore (SRIS), Singapore’s National Skin Centre, Department of Dermatology, Kyoto University Graduate School of Medicine, Japan, and industry partner Galderma.

More people should be screened for abdominal aortic aneurysm

(HealthDay)—A majority of patients who undergo repair for ruptured abdominal aortic aneurysms (AAAs) do not qualify for screening, according to a study published online in the August issue of the Journal of Vascular Surgery. Kirsten D. Dansey, M.D., from the Beth Israel Deaconess Medical Center in Boston, and colleagues used...

A new species of otter discovered in Germany

Researchers from the Universities of Tübingen and Zaragoza have discovered a previously unknown species of otter from 11.4-million-year-old strata at the Hammerschmiede fossil site. The excavation site in the Allgäu region of Germany became world-renowned in 2019 for discoveries of the bipedal ape Danuvius guggenmosi. The new species, published today...

Mistrust of government tops reasons for vaccine hesitancy

People’s trust in the government’s approval of a safe and effective vaccine against COVID-19 is the biggest driver of vaccine uptake, an Australian study has found. Second on the list of motivations identified in the study is the perceived effectiveness of the vaccine to protect others in the community. The...

Ultrathin self-healing polymers create new, sustainable water-resistant coatings

CHAMPAIGN, Ill. — Researchers have found a way to make ultrathin surface coatings robust enough to survive scratches and dings. The new material, developed by merging thin-film and self-healing technologies, has an almost endless list of potential applications, including self-cleaning, anti-icing, anti-fogging, anti-bacterial, anti-fouling and enhanced heat exchange coatings, researchers said.

Researchers identify tube-forming proteins in mycobacterial outer envelope

​The research team led by Prof. GONG Weimin from the University of Science and Technology of China (USTC), collaborating with Dr. ZHOU Zhenghong from the University of California, Los Angeles (UCLA), clarified the architecture of tube-forming proteins that function as a protein transport tube across the mycobacterial outer envelope. The study was published in Science Advances.

Climatically driven landscape evolution during warm periods

Max Planck Institute for Evolutionary Anthropology. The "Lichtenberg" project is an experimental laboratory for landscape research: By means of a drilling campaign and with the support of the State Office for Mining, Energy and Geology (LBEG), the research team started a comprehensive investigation of the area near the village of Lichtenberg about three years ago, because the sediments offer a unique insight into the history of the Eemian.

Study suggests earliest use of bone tools to produce clothing in Morocco 120,000 years ago

A new study led by Arizona State University paleoanthropologist Curtis Marean and ASU doctoral graduate Emily Hallett details more than 60 tools made of bone and one tool made from the tooth of a cetacean, which includes whales, dolphins, and porpoises. These finds, first unearthed from Contrebandiers Cave, Morocco in 2011, are highly suggestive proxy evidence for the earliest clothing in the archaeological record and attest to the pan-African emergence of complex culture and specialized tool manufacture.
