Phys.org / When uncertainty spikes, chasing rewards backfires and a more informed strategy pulls ahead
Humans and other animals are constantly required to make decisions under uncertain conditions or while in rapidly changing environments. Past psychology and biology studies showed that some decision-making strategies can ...
Medical Xpress / Discovery of fat-burning 'switch' could lead to advances in bone disease treatments
Scientists' discovery of a molecular "switch" that activates an energy-burning pathway in mice has the potential to lead to new treatments for bone disease. The study, published in Nature, sheds new light on brown fat. Unlike ...
Phys.org / Researchers uncover chemical origins of the Perseus cluster of galaxies
An international team of researchers has developed new stellar and supernova models to explain the mysterious elemental abundance patterns left by billions of supernova explosions around the Perseus constellation, which have ...
Medical Xpress / How the brain decides which memories belong together could reshape schizophrenia research
Our memories of past events are typically not isolated, but they are linked to other related memories. This ability to establish connections between related memories is highly advantageous, as it helps us to recognize familiar ...
Medical Xpress / How a seconds-long toe scan with AI could widen access to PAD screening
Peripheral artery disease (PAD) affects 8 to 12 million Americans. The condition is caused by the buildup of plaque (cholesterol and other substances) inside blood vessels, restricting blood flow to the legs and disproportionately ...
Phys.org / Radio telescopes confirm 3.3-million-light-year halo in unusually quiet galaxy cluster
Astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) and the MeerKAT radio telescope to observe a galaxy cluster known as RXCJ0232–4420. Results of the new observations, published April 29 on the ...
Medical Xpress / Your address, ancestry and gut may be steering aging in ways medicine has barely begun to map
Researchers at the Stanford School of Medicine have found that ethnicity and geography may influence human molecular makeup—from metabolism and immunity to gut microbiota and biological aging. The findings, published in Cell, ...
Medical Xpress / Blood test that detects tumor DNA could help guide treatment when cancer has spread
A blood test that detects tumor DNA circulating in the bloodstream may help select the most effective treatment options for cancer patients whose tumors have started to spread, according to one of the largest randomized controlled ...
Medical Xpress / Japan pharmaceutical firm warns against rare diseases drug after deaths
A Japanese pharmaceutical firm has warned doctors against prescribing a drug for rare autoimmune diseases to new patients following the deaths of 20 people who took it.
Phys.org / A child's environment may shape how their brain solves problems
For decades, researchers have documented an achievement gap between children from higher- and lower-income families. On average, children with more resources perform better in school and on cognitive tests.
Phys.org / New reversible conductive glue could reshape electronics repair, recycling, and material recovery
A collaboration between electrical and chemical engineers at Newcastle University is responsible for a reversible glue that can change how we recycle electronic waste. The team has already demonstrated reversible adhesive ...
Medical Xpress / AI coach rewrites the rules of cardiovascular research
Every day, millions of Americans open a fitness app, glance at their step count, and may even feel a mild pang of guilt before closing it again. The problem with most health tracking technology is that it watches your activity, ...
