Phys.org / Antarctica sits above Earth's strongest 'gravity hole.' Now we know how it got that way
Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest beneath the frozen continent ...
Tech Xplore / Why AI may overcomplicate answers: Humans and LLMs show 'addition bias,' often choosing extra steps over subtraction
When making decisions and judgments, humans can fall into common "traps," known as cognitive biases. A cognitive bias is essentially the tendency to process information in a specific way or follow a systematic pattern. One ...
Phys.org / Brain responses to wildlife images can forecast online engagement—and help conservation messaging
What types of photos make people reach for their wallets? New Stanford University-led research suggests that brain activity can help forecast which wildlife images will inspire people to engage online and donate to conservation ...
Medical Xpress / Study reveals how children with disruptive behavior get 'stuck' in specific brain states
Youth with related behavior challenges may have trouble moving between different brain states, according to a new study from Yale Child Study Center. Their brains appear to get stuck in states with disrupted connections in ...
Phys.org / Bird flu ravaging Antarctic wildlife, scientist warns
Scientists are sounding the alarm over the spread of bird flu across Antarctica, with a leading Chilean researcher telling AFP Tuesday of an observed strain "capable of killing 100% of infected fauna."
Medical Xpress / AI-powered liquid biopsy can classify pediatric brain tumors with 92% accuracy
Liquid biopsies, which test body fluids that contain cancerous material, including circulating tumor DNA (ctDNA), are a noninvasive way to learn about a cancer's biology. However, technological limitations with the small ...
Phys.org / New species of ancient crocodile named in honor of Welsh school teacher
A new species of crocodylomorph dating to about 215 million years ago has been described from the U.K. It has been called Galahadosuchus jonesi in recognition of David Rhys Jones, a secondary school physics teacher from Ysgol ...
Medical Xpress / FDA approves noninvasive Optune Pax device for advanced pancreatic cancer
The U.S. Food and Drug Administration has approved a first-of-its-kind, noninvasive device, the Optune Pax, for the treatment of adult patients with locally advanced pancreatic cancer. Approval of Optune Pax was granted to ...
Medical Xpress / With the right prompts, AI chatbots can analyze biomedical big data accurately
In an early test of how AI can be used to decipher large amounts of health data, researchers at UC San Francisco and Wayne State University found that generative AI tools could perform orders of magnitude faster—and in ...
Phys.org / Elusive lithium-ion anode binder finally seen with pioneering technique
Researchers at the University of Oxford have developed a powerful new method to visualize an essential lithium-ion battery electrode component that had been extremely difficult to trace before. The discovery, published in ...
Phys.org / Amazon rainforest flipped to carbon source during 2023 extreme drought, study shows
The Amazon rainforest is of crucial importance to the Earth's ecosystem, given its capacity to store substantial amounts of carbon in its vegetation. In 2023, the region experienced unusually high temperatures, reaching 1.5°C ...
Medical Xpress / Developmental 'switch' in brain may shape lifelong obesity risk
Researchers at UT Southwestern Medical Center have discovered that a crucial developmental process in the brain's hypothalamus may influence how susceptible individuals are to obesity. Their preclinical findings, published ...
