Tech Xplore / AI-based model measures atomic defects in materials
In biology, defects are generally bad. But in materials science, defects can be intentionally tuned to give materials useful new properties. Today, atomic-scale defects are carefully introduced during the manufacturing process ...
Phys.org / Limits of protein evolution could reshape ideas about early life
The number of known proteins is infinitely small in comparison to the universe of possible proteins, which could in theory be realized. Yet these known proteins are the only major training ground for future protein design. ...
Phys.org / Cells under stress: How a chemotherapy drug damages RNA
The integrity of DNA and RNA is essential for every cell. DNA contains the genetic information for proteins, while RNA serves as a working copy of individual genes and is required for the synthesis of proteins. Unlike DNA ...
Medical Xpress / Common disinfectant chemicals far more toxic when inhaled, study finds
Breathing in common disinfectant chemicals known as quaternary ammonium compounds, or QACs, may be far more harmful than swallowing them, according to a mouse study led by researchers at the University of California, Davis. ...
Tech Xplore / Q&A: Robots can't feel, but novel sensors could change that
A research team, including Huanyu "Larry" Cheng, James L. Henderson Jr. Memorial Associate Professor of Engineering Science and Mechanics at Penn State, is using pressure sensors—tiny devices, roughly the size of a paperclip, ...
Phys.org / Two organs, one brain area: How fish orient themselves in the water
Using zebrafish, researchers from Osaka Metropolitan University (OMU) have identified the tegmentum region in the fish midbrain as the area where light input from both the fish's eyes and the pineal organ—the "third eye"—is ...
Phys.org / Soil bacteria break down toxic chemicals in the environment
Many aromatic compounds, such as phenols, cresols and styrenes, are toxic to organisms and harmful to the environment. They can accumulate as a result of industrial processes and harm ecosystems. Soil bacteria can help to ...
Medical Xpress / Mutation map reveals how amylin mutations influence type 2 diabetes
Researchers at the Institute for Bioengineering of Catalonia (IBEC) have produced a mutational map showing how mutations in amylin—a hormone that plays a key role in glucose regulation—affect its tendency to form toxic amyloid ...
Medical Xpress / Subtle brainwave patterns detected during sleep EEG can help predict dementia risk
Our date of birth doesn't always match the age of our brain. How old our brain really is depends on our biological age, shaped by the wear and tear our cells experience over time. Genetics, environmental factors, and lifestyle ...
Phys.org / Copper-loaded starch nanoparticles can target bacteria in microbial communities
Bacteria are a major cause of infections and death in hospital settings, due—in part—to the rising incidence of antibiotic resistance. In the United States, antibiotic-resistant bacteria are involved in more than 2 million ...
Medical Xpress / Craving in addiction may alter how the brain makes decisions
For people with an addiction, craving—the strong desire for a substance—can affect their decision-making, new research shows. And how craving affects a decision can depend on what's at stake. The finding, published in Nature ...
Phys.org / Tracing the evolutionary history of chemical warfare between plants and insects
A new study published in Nature Ecology & Evolution connects plant and insect physiology, chemical ecology, molecular function, and evolutionary analysis to offer a new perspective on plant–insect coevolution. The research ...
