New treatment target identified for radiation-resistant cervical cancer

Christine Bronstein took at home colon cancer test after seeing blood in her stool. It was positive, but her doctor texted: "You don't have cancer :)"

The pharmaceutical company Pfizer has voluntary recalled a blood pressure medication for the second time in a month. Pfizer is recalling five lots of blood pressure medicine Accupril because of elevated levels of a nitrosamine, Nnitroso-quinapril, the company said in a news release posted Friday on the FDA website. Nitrosamines...

Though helpful for cleaning and disinfecting, Lysol contains a number of harmful chemicals that can irritate your eyes, skin, and respiratory system.

MILLIONS of Brits have been urged to take up a rapid test to see if they have bowel cancer. The Health Secretary has called on men over 60 to make sure they have the life-saving checkups. It couldn't be easier - with a home testing kit on offer, or use...

It’s a story many have heard before. COVID-19 enters a household whether through a spouse, parent, sibling or caretaker – but despite extensive exposure, not everyone gets sick. [. SEE:. Latest Coronavirus and Vaccine News ]. And it could be a more common occurrence than some think. The...

Walking at a brisk pace for just 75 minutes every week could cut your risk of depression, a new study finds. The World Health Organization recommends everyone should exercise for at least two-and-a-half hours every seven days. But researchers at Cambridge University, England, found adults who got half as much...

Tragic events like wars, famines, earthquakes, and accidents create fearful memories in our brain. These memories continue to haunt us even after the actual event has passed. Luckily, researchers from Tokyo University of Science (TUS) have recently been able to understand the hidden biochemical mechanisms involved in the selective suppression of fearful memories, which is called fear extinction. The researchers, who had previously demonstrated fear extinction in mice using the chemically synthesized compound "KNT-127," have now identified the underlying mechanism of this compound's action. Their findings have been published recently in Frontiers in Behavioral Neuroscience.

Like storm waves battering a ship, new versions of the SARS-CoV-2 virus have buffeted the world one after another. Recently, scientists keeping tabs on these variants noticed a trend: Many carry the same set of three mutations. In a new study in ACS' Biochemistry, researchers examined how these mutations change the way a key piece of the virus functions. Their experiments show how this triad alters traits it needs to cause and sustain COVID-19 infection.

UT Southwestern researchers have discovered a molecular pathway that allows cells to sense when their lipid supplies become depleted, prompting a flurry of activity that prevents starvation. The findings, reported in Nature, might someday lead to new ways to combat metabolic disorders and a variety of other health conditions. "Lipids...

The ALICE collaboration at the Large Hadron Collider (LHC) has made the first direct observation of the dead-cone effect—a fundamental feature of the theory of the strong force that binds quarks and gluons together into protons, neutrons and, ultimately, all atomic nuclei. In addition to confirming this effect, the observation, reported in a paper published today in Nature, provides direct experimental access to the mass of a single charm quark before it is confined inside hadrons.

Moments after being taken off life support, an anonymous Bay Area woman gave the most abundant of gifts: 17 different tissues and organs. Some were transplanted into strangers in need, but many others were rushed off on a unique mission. They were donated for research—contributing to a first-ever detailed "cell atlas," a reference guide of cell types and behaviors that will transform our understanding of health and disease.

Gaze aversion, lack of emotional expression, repetitive body movements, or speaking in monolog tone can sway people's judgment of another's credibility and honesty—notably in the criminal justice system. However, Flinders University psychology researchers warn these behaviors are also common in certain mental health and developmental conditions, making some individuals...

Biomarkers are components that may be present in biological samples and are related to specific diseases. Therefore, doctors can analyze biological samples from a patient to check their health condition or to monitor the progress of a specific therapy. Typically, these samples need to be purified and diluted before the analysis, and current medical diagnostic techniques rely on health care facilities and laboratories for these routine analyses. This is a lengthy process that requires trained personnel and expensive instrumentation to extract, transport, store, process, and analyze the samples in centralized locations. Moreover, during a period of global crisis like the ongoing pandemic, the pressure of thousands of analysis requests can saturate and collapse the health care system.

Researchers have developed a CRISPR-Cas9 approach to enable gene editing in cockroaches, according to a study published by Cell Press on May 16th in the journal Cell Reports Methods. The simple and efficient technique, named "direct parental" CRISPR (DIPA-CRISPR), involves the injection of materials into female adults where eggs are developing rather than into the embryos themselves.

The cell membrane, which contains a hydrophilic exterior and a hydrophobic interior, opens and closes ion channels like a water faucet and converts a physicochemical stimulus into an electrical signal that is then transmitted to cells. Until recently, the limited ability of an artificial cell membrane structure to only last a maximum of five days has been a hurdle.

For many years after discovering a diverse population of sometimes dangerous microbes constantly living in our intestines, scientists described the situation as a form of living with the enemy. But when it comes to commensal populations of the fungus Candida albicans, the dreaded invader may be better seen as a helpful friend arriving with gifts.

Having a head is quite an advantage. Although this may sound banal, it had to be tested in a long evolutionary process: As animal life developed, invertebrates initially dominated the oceans. These had already developed head structures, but the development of a novel, improved head led to the success of vertebrates. This "new head" allowed a wide spatial distribution and multiplication of sensory cells, and thus a much better perception of the environment. This was also essential for the development of a predatory lifestyle.

A small group of researchers including Dennis Kurzbach from the Faculty of Chemistry of the University of Vienna just published in Nature Protocols an advanced NMR (Nuclear Magnetic Resonance) method to monitor fast and complicated biomolecular events such as protein folding. Protein folding was long considered as one of the...
