Phys.org / When humidity changes, so do the colors of sweat bees
Nature is a riot of color. In the animal kingdom, many species, from insects to cephalopods, use their permanent color or change it for communication, camouflage, and thermoregulation. While this type of reversible shift ...
Phys.org / Common soil fungus could cut pesticide use while helping tomatoes grow stronger
Trichoderma species—a common fungus found in soils—have varying abilities to promote tomato plant growth and differentially affect the abundance of certain soil bacteria, according to a study led by researchers at Penn State.
Medical Xpress / A global fertility reversal is unfolding, and it could upend who becomes parent in decades ahead
With few exceptions, birth rates are falling worldwide. What does this mean? Put simply, the fertility rate describes the average number of children a woman is expected to have over the course of her life, if exposed to the ...
Tech Xplore / OpenAI launches GPT-5.5 as rivals race to build more autonomous AI assistants
OpenAI released a new model it touts as its best yet for handling research work like making improved versions of itself, as rapid-fire releases by AI rivals pick up pace.
Phys.org / Scientists discover how the Twelve Apostles were formed—and their real age
Scientists at the University of Melbourne have uncovered for the first time how Australia's iconic Twelve Apostles were formed, finding tectonic plate movements over millions of years lifted and tilted the giant structures ...
Science X / They lost weight and did everything right, but one group still faces type 2 diabetes years later
A healthy diet, weight loss, and increased physical activity can effectively prevent type 2 diabetes. However, not all individuals at elevated diabetes risk benefit equally from lifestyle interventions. People classified ...
Phys.org / Amazon recovery masks diversity loss as fires, droughts and windstorms reshape forest edges
Even after fires, severe droughts, and windstorms, the vegetation in degraded Amazonian forests demonstrates a high capacity for regeneration, including tree species. However, recovery occurs under new ecological conditions, ...
Medical Xpress / Impaired cell recycling leads to muscle weakness in rare genetic disorder
Myofibrillar myopathy type 6 (MFM6) is a rare genetic muscle disorder that leads to severe muscle weakness and a drastically shortened life expectancy due to a disruption in muscle protein regulation. Researchers at the University ...
Phys.org / A third of animal habitats on land could experience multiple extreme events by 2085, new study suggests
By 2085, 36% of species' current habitats on land could be exposed to multiple types of climate-driven extreme events such as heat waves, fire or floods if warming continues to rise into the latter half of the century. The ...
Tech Xplore / SmartDJ lets users reshape audio experiences with simple words
Penn Engineers have developed SmartDJ, an AI-powered editor that lets users modify immersive audio environments with simple instructions in everyday language, with potential applications in virtual reality, augmented reality, ...
Phys.org / Cold fronts in nearby galaxy group may redistribute metals, Chandra and GMRT data reveal
Astronomers from South Africa and India have analyzed archival data from the Chandra X-ray Observatory and Giant Metrewave Radio Telescope (GMRT) regarding a nearby small galaxy group known as IC 1262. Results of the new ...
Medical Xpress / Genetic study reveals likely cause of common heart valve defect
New clues from genetic research may help explain what causes the most common heart defect present at birth. Researchers at KTH Royal Institute of Technology and Karolinska Institutet have identified rare DNA changes during ...
