Astronomers discover a planet that's rapidly disintegrating, producing a comet-like tail

A planet 140 light-years from Earth is rapidly coming apart due to its close proximity to its star. The roasting planet is effectively evaporating away: It sheds an enormous amount of surface minerals as it whizzes around its star. Read more ›

Study reveals gaps in flu treatment for high-risk adults

A multi-state study reveals that many high-risk adults diagnosed with influenza (flu) in emergency departments and urgent care centers are not receiving timely antiviral treatment. Researchers found that only slightly more than half of these patients received antiviral prescriptions, and of those, only 80 percent were filled. This gap in treatment could increase the risk of severe flu complications, particularly for older adults and those with underlying conditions. Read more ›

How dopamine helps us learn to avoid bad outcomes

Dopamine is the brain's motivational spark, driving us to chase what feels good, say scrolling another reel on social media, and steer clear of what doesn't, like touching a hot stove. But scientists haven't fully understood how dopamine helps us learn to avoid bad outcomes -- until now. A new study shows that dopamine signals in two key brain areas involved in motivation and learning respond differently to negative experiences,... Read more ›

Better feed, fewer burps: Scientists target dairy gas emissions

Researchers are testing a new type of cattle feed that could help dairy cows release less methane gas from burps and flatulence and use nutrients more efficiently. Because methane traps heat in the atmosphere, reducing these emissions could make dairy farming more environmentally friendly and sustainable. Read more ›

Adolescents who sleep longer perform better at cognitive tasks

Adolescents who sleep for longer -- and from an earlier bedtime -- than their peers tend to have improved brain function and perform better at cognitive tests, researchers have shown. But the study of adolescents in the US also showed that even those with better sleeping habits were not reaching the amount of sleep recommended for their age group. Read more ›

Drugs targeting 'zombie cells' show promise for treating chronic back pain

In a preclinical study, two drugs targeting 'zombie cells' have been shown to treat the underlying cause of chronic low back pain. The condition affects millions of people worldwide. Current treatments manage symptoms through painkillers or surgery, without addressing the root cause. Read more ›

Novel treatment approach for language disorder shows promise

Neuroscientists have developed a new treatment approach for a language disorder that combines traditional speech therapy with noninvasive electrical stimulation of the brain. Brain stimulation helped induce neuroplasticity, the brain's capacity to continue to reorganize and learn. Read more ›

High-fat, high-sugar diets impact cognitive function

New research links fatty, sugary diets to impaired brain function. The findings build on a growing body of evidence showing the negative impact of high-fat, high-sugar (HFHS) diets on cognitive ability, adding to their well-known physical effects. Read more ›

What if Mother Earth could sue for mistreatment?

The study highlights the transformative potential of the Rights of Nature, which views nature as a rights-bearing entity, not merely an object of regulation and subjugation by extractive industries. The Llurimagua case -- a dispute over a mining concession in Ecuador's cloud forest -- illustrates this approach, providing a unique opportunity to rethink Earth system governance. Read more ›

How activity in Earth's mantle led the ancient ancestors of elephants, giraffes, and humans into Asia and Africa

What roils beneath the Earth's surface may feel a world away, but the activity can help forge land masses that dictate ocean circulation, climate patterns, and even animal activity and evolution. In fact, scientists believe that a plume of hot rocks that burst from the Earth's mantle millions of years ago could be an important part in the story of human evolution. Read more ›

Omnivorous? Vegan? Makes no difference to muscle building after weight training, study finds

A new study asked three questions about muscle protein synthesis in response to a nine-day diet and weight training regimen: First, does the source of protein -- plant or animal-based -- make any difference to muscle gain? Second, does it matter if total daily protein intake is evenly distributed throughout the day? And third, does a moderate but sufficient daily protein intake influence any of these variables? The answer to... Read more ›

Simulations predict how pesticides may affect honeybee colonies

Honeybees are essential pollinators for agriculture and natural ecosystems. Stressors like climate change, habitat loss and pesticide exposure threaten their ability to forage for pollen, a critical resource for colony survival. Researchers demonstrate that an artificial intelligence (AI)-based monitoring system combined with a computer model can link the exposure of neonicotinoid pesticides on individual honeybees to the health of the whole colony.

A light-activated probe reveals TB immune system evasion mechanisms

Tuberculosis (TB) is an infectious disease that kills more than a million people worldwide every year. The pathogen that causes the disease, Mycobacterium tuberculosis, is deadly in part because of its complex outer envelope, which helps it evade immune responses of infected hosts. Researchers have now developed a chemical probe to study a key component of this envelope. Their results provide a step toward finding new ways of inactivating the... Read more ›
