Ecologists have long sought clarity on the dietary habits of different animal species. For scientists, it wasn't obvious how herbivores in Yellowstone National Park, who subsist on grasses, wildflowers and trees, could compete for enough of those foods to survive the winter. Over two years, with the aid of cutting-edge molecular biology tools and GPS tracking data, the researchers were able to determine not only what herbivores in Yellowstone eat,... Read more ›

By staring into the hellish landscape of Jupiter's moon Io -- the most volcanically active location in the solar system -- astronomers have been able to study a fundamental process in planetary formation and evolution: tidal heating. Read more ›

As the school year revs up, a renowned child developmental psychologist highlights the robust benefits of pretend play on cognitive, social, and emotional development in children and cautions how 'learning through play' has changed with the demands of contemporary society. Given natural selection's shaping of childhood for the acquisition and refinement of species-adapted social-cognitive skills -- much through pretend play -- he says it's unfortunate that modern culture is ignoring...

Findings suggest that new genes can form by repurposing fragments of ancestral genes while incorporating entirely new coding regions (the protein-coding parts of the DNA). This innovative concept bridges the gap between entirely new gene formation from noncoding regions and the more traditional model in which new functions can arise from duplicated genes. Read more ›

An examination of millions of patient visits to primary care physicians shows that mental health concerns are second only to musculoskeletal complaints in everyday care. One in nine patients was seeking care primarily because of a mental health concern. In mid-life, that number rises to one in five patients. Mental health concerns are as prevalent as respiratory and cardiovascular complaints, and are more common than infections, injuries, digestive, skin, urological... Read more ›

The beliefs we hold develop from a complex dance between our internal and external lives. A recent study uses well-known formalisms in statistical physics to model multiple aspects of belief-network dynamics. This multidimensional approach to modeling belief dynamics could offer new tools for tackling various real-world problems such as polarization or the spread of disinformation. Read more ›

By tracking the changes in prostate cancer cells over time, researchers have found that activation of the MYC gene -- a well-known cancer-causing gene -- sets off a cascade of events that leads to both initiation and progression of the disease. Read more ›

Researchers find that despite the enactment of 12-month contraceptive supply policies in 19 U.S. states, most patients do not receive a long-term prescription. Read more ›

Scientists have discovered the cuisine preferences of two resident killer whale populations, also known as orcas: the Alaska residents and the southern residents, which reside primarily in the Salish Sea and off the coast of Washington, British Columbia, Oregon and northern California. The two populations show broad preference for salmon, particularly Chinook, chum and coho. But they differ in when they switch to hunting and eating different salmon species, as... Read more ›

Chemists have developed a generative AI model that can make it much easier to determine the structures of powdered crystal materials. The prediction model could help researchers characterize materials for use in batteries, magnets, and many other applications. Read more ›

Researchers have isolated 18 bacterial strains from stool from healthy people that could potentially be a more effective treatment for antibiotic-resistant gut infections. The team found that these strains suppress the growth of Enterobacteriaceae and alleviate inflammation in the guts of mice by competing with the harmful bacteria for carbohydrates and preventing them from colonizing the intestine. The findings could lead to the development of a microbial transplant for patients... Read more ›

Researchers report significant strides in enhancing early diagnosis of bipolar disorder in adolescents. They demonstrate the efficacy of integrating multimodal MRI with behavioral assessments for greater diagnostic precision. Bipolar disorder is a severe neuropsychiatric condition that often emerges during adolescence and is characterized by extreme mood swings. Read more ›

A new way of looking at tooth enamel could give scientists a path to deeper understanding of the health of human populations, from the ancient to the modern. The method examines two immune proteins found embedded in human tooth enamel: immunoglobulin G, an antibody that fights infection, and C-reactive protein, which is present during inflammation in the body.

An international group of researchers says two decades of research have generated sufficient knowledge about the sources and effects of microplastics to allow world leaders to agree measures to address them. The argument comes 20 years after the first ever study to coin the term microplastics to describe the microscopic fragments of plastics in our ocean. Read more ›

A new study offers the most detailed glimpse yet into how Earth's surface temperature has changed over the past 485 million years. The data show that Earth has been and can be warmer than today -- but humans and animals cannot adapt fast enough to keep up with human-caused climate change. Read more ›
