Phys.org / New measure captures how scientists' identities shift across academic disciplines
Does the academic discipline of a scientist's doctorate accurately capture their disciplinary affiliation decades later? Consider a scientist who earned a doctorate in physics 25 years ago who now studies climate change, ...
Phys.org / Nepal flood disaster exposes cascading threats in Himalayas
A catastrophic flood in Nepal that left thousands missing began with a collapse of ice and rock high in the mountains—a warning that disaster planning must prepare for chains of hazards, not isolated events, experts say.
Medical Xpress / Fat cells retain hunger signal after weight loss, potentially driving obesity relapse
Two enduring biological mysteries have remained unsolved for decades: why almost everyone who loses weight gains it back, no matter how they lost it, and why obesity passes from mother to child at rates that diet and environment ...
Phys.org / Bite, buzz, release: How bees make flowers give up their pollen
Life is not always easy for a bee: Not all plants place their pollen outside. Some flowers have to be set to vibrating before the pollen can get out of their tube-like stamens. Certain bee species have developed a special ...
Phys.org / Unusual bonds reorganize structure and magnetism in vanadium material
While chemical bonds usually determine the structure and properties of a material, bonds between neighboring metal atoms can also change as temperature or other conditions change. These changes can lead to unusual electronic ...
Phys.org / Shapeshifting plant roots rely on a balance of anatomy, metabolism, and microbes to maximize survival
Scientists have identified the mechanisms that allow plants to change their root anatomy to maximize survival when nutrients are scarce. The findings could pave the way for developing new ways to improve beneficial plant-microbe ...
Medical Xpress / New findings link obesity to loss of natural breast cancer protection
A research team at Huntsman Cancer Institute at the University of Utah (the U) has found that obesity prevents a biological process that kills cancerous cells, revealing a possible reason obesity is a risk factor for breast ...
Medical Xpress / PET/MRI improves presurgical lesion detection in pediatric epilepsy
In children with difficult-to-diagnose epilepsy, PET/MRI can pinpoint areas of the brain responsible for seizures, even when MRI scans are negative or inconclusive. A new study of a large pediatric cohort, including children ...
Phys.org / Fertilizers and extreme heat are damaging coral reefs in the Gulf of Mexico, isotope analyses reveal
Who isn't familiar with the colorful coral reefs from movies like "Finding Nemo" or "The Little Mermaid"? Unfortunately, the reality is often quite different, as these vital ecosystems are under pressure worldwide. Climate ...
Medical Xpress / Blood and gene tests predict Alzheimer's symptoms three to six years ahead
Columbia University researchers have identified a way to help predict when people at high risk of developing Alzheimer's are likely to develop their first symptoms, a finding that could help physicians decide when to prescribe ...
Phys.org / Healthy checkout policy shows promise for reducing soda sales and increasing healthy snack purchases
In March 2021, Berkeley, Calif., became the first city in the world to ban the display of sugary beverages and snacks in store checkout lanes, where candy, chocolate and soda are commonly placed to encourage impulse buying ...
Medical Xpress / New video game could help reveal how people with autism perceive the world
People with autism often come at life from a different angle—seeing details others miss, focusing on patterns rather than faces, experiencing heightened or dimmed physical sensations. Although researchers have tracked some ...
