Phys.org / Computational model guides lighting design to improve color discrimination in aging eyes
Researchers have developed a new computational model that accounts for the effects of aging on our eyes' ability to discriminate color. It could help guide lighting designs that make it easier for older adults to perceive ...
Phys.org / New solar model maps sun more accurately by checking far-side activity
A Southwest Research Institute (SwRI)-led team has developed an improved model for predicting solar events that incorporates activity on the far side of the sun. The team studied near-simultaneous maps of the whole solar ...
Phys.org / Variations in the human vocal tract could have influenced language diversity
The anatomical differences in our vocal tracts could be one of the sources of our Tower of Babel—the vast difference in languages spoken around the world, according to a study published in the open-access journal PLOS Biology ...
Phys.org / Natural RNA modifications in archaea mirror those used in medicine
RNA therapeutics open up new possibilities for the targeted and precise treatment of diseases. To ensure that RNA molecules remain stable in the body and can reliably exert their effects, they undergo specific chemical modifications. ...
Phys.org / Random mutations turn RNA droplets into cell-like structures that move and store cargo
A small number of random genetic mutations cause simple RNA droplets to transform into cell-like structures. In this process, they form cavities, can move and are able to take up cargo.
Phys.org / Modified lentil protein mimics fat in non-fat yogurt
Modified lentil protein can act like fat in nonfat foods, especially yogurt, delivering creaminess and richness, according to a new study led by researchers at Penn State. The work, published in Food Chemistry, is the latest ...
Phys.org / Reaching net zero sooner could limit long-lasting El Niño-like shift in the Pacific
Reaching net zero sooner would limit long-lasting changes to El Niño and the tropical Pacific, new climate modeling suggests, although heat stored deep in the ocean means changes to the tropical Pacific could persist for ...
Phys.org / A closer look at hard-to-see cells could answer new questions about nerve damage and recovery
Under the microscope, mitochondria inside healthy terminal Schwann cells form a web of interconnected branches, with tiny doughnut-shaped loops appearing near where the cells branch and split.
Phys.org / Powerful X-rays reveal unexpected roles for water in enzymes linked to cancer and penicillin
In biology, a group of enzymes called 2-oxoglutarate-dependent oxygenases is responsible for catalyzing a wide range of reactions that play a role in everything from how genetic code is used by cells to the synthesis of antibiotics.
Phys.org / Satellite model finds Alpine peatlands may be smaller than official maps show
Peatlands in the Alps are mostly small, scattered and difficult to access. As a result, up-to-date information on their extent and condition is often lacking. An international research team, including researchers from the ...
Phys.org / New electrochemical sensor could make food quality testing faster and less expensive
Researchers at the Oregon State University College of Science have developed a new electrochemical sensor for rapidly and accurately detecting a naturally occurring compound widely used in the food, beverage and fragrance ...
Phys.org / Chemical surroundings, not size alone, help glucose-processing enzyme stay active as temperatures rise
Cells must produce energy despite changing conditions. But what keeps metabolic enzymes functional during temperature fluctuations? A team led by professor Simon Ebbinghaus and Dr. Harshita Rastogi at Ruhr University Bochum ...
