A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health, including thinking clarity, emotional well-being, and sense of purpose.

A powerful new synthetic opioid, up to 1000 times stronger than morphine, has emerged in Adelaide’s street drug supply, and researchers are sounding the alarm. Nitazenes, often hidden in heroin or fentanyl, have already caused dozens of deaths in Australia, with most victims unaware they were exposed. Even more concerning, researchers found the sedative xylazine mixed in, echoing deadly drug combinations seen in the U.S. Read more ›

Ape behavior just got a name upgrade — “scrumping” — and it might help explain why humans can handle alcohol so well. Researchers discovered that African apes regularly eat overripe, fermented fruit off the forest floor, and this habit may have driven key evolutionary adaptations. By naming and classifying this behavior, scientists are hoping to better understand how alcohol tolerance evolved in our ancestors — and how it might have... Read more ›

Scientists have discovered the oldest direct evidence of betel nut chewing in Southeast Asia by analyzing 4,000-year-old dental plaque from a burial in Thailand. This breakthrough method reveals invisible traces of ancient plant use, suggesting psychoactive rituals were part of daily life long before written records. Read more ›

Women who drank heavily, even though they strongly wished to avoid pregnancy, were 50% more likely to become pregnant than those who drank little or not at all, according to new research. Surprisingly, cannabis use didn t show the same risk. Read more ›

In an exciting breakthrough, researchers have identified cancer drugs that might reverse the effects of Alzheimer's disease in the brain. By analyzing gene expression in brain cells, they discovered that some FDA-approved cancer medications could reverse damage caused by Alzheimer's. Read more ›

GLP-1 drugs like Ozempic are transforming weight loss, but a new UVA study warns they're not improving a critical measure of health: cardiorespiratory fitness. While these medications help people shed fat, they also strip away vital muscle mass—raising concerns about long-term heart health, physical function, and mortality. The researchers urge combining treatment with exercise, protein intake, and possibly future drugs to avoid hidden downsides of rapid weight loss. Read more ›

Potent statins are the best-proven weapon against heart disease, especially when paired with lifestyle changes. Most people aren’t active enough—and many are underdiagnosed—so starting treatment strong is key. Read more ›

A newly mapped neural circuit shows how our skin senses cool temperatures and sends that info to the brain, revealing an unexpected amplifier in the spinal cord and offering insight into cold-related pain. Read more ›

A group of Australian scientists has uncovered a new way to fight some of the toughest cancers by targeting an overlooked cellular process called minor splicing. This tiny but vital mechanism turns out to be essential for the growth of certain tumors, especially those driven by KRAS mutations — a common but hard-to-treat culprit in cancer. By blocking minor splicing, researchers triggered DNA damage and activated the body’s own cancer-defense... Read more ›

Scientists have used artificial intelligence to upgrade plant immune systems, potentially revolutionizing how crops like tomatoes and potatoes can defend against harmful bacteria. By reengineering plant receptors that recognize bacterial threats, they are enhancing plant resistance and preparing for a future of more resilient crops. Read more ›

A global study of over 88,000 adults reveals that poor sleep habits—like going to bed inconsistently or having disrupted circadian rhythms—are tied to dramatically higher risks for dozens of diseases, including liver cirrhosis and gangrene. Contrary to common belief, sleeping more than 9 hours wasn't found to be harmful when measured objectively, exposing flaws in previous research. Scientists now say it's time to redefine “good sleep” to include regularity, not... Read more ›

A fish thought to be evolution’s time capsule just surprised scientists. A detailed dissection of the coelacanth — a 400-million-year-old species often called a “living fossil” — revealed that key muscles believed to be part of early vertebrate evolution were actually misidentified ligaments. This means foundational assumptions about how vertebrates, including humans, evolved to eat and breathe may need to be rewritten. The discovery corrects decades of anatomical errors, reshapes...

Scientists at UC Merced have engineered artificial cells that can keep perfect time—mimicking the 24-hour biological clocks found in living organisms. By reconstructing circadian machinery inside tiny vesicles, the researchers showed that even simplified synthetic systems can glow with a daily rhythm—if they have enough of the right proteins.

Deep beneath the Swiss-French border, the Large Hadron Collider unleashes staggering amounts of energy and radiation—enough to fry most electronics. Enter a team of Columbia engineers, who built ultra-rugged, radiation-resistant chips that now play a pivotal role in capturing data from subatomic particle collisions. These custom-designed ADCs not only survive the hostile environment inside CERN but also help filter and digitize the most critical collision events, enabling physicists to study... Read more ›

Researchers are exploring AI-powered digital twins as a game-changing tool to accelerate the clean energy transition. These digital models simulate and optimize real-world energy systems like wind, solar, geothermal, hydro, and biomass. But while they hold immense promise for improving efficiency and sustainability, the technology is still riddled with challenges—from environmental variability and degraded equipment modeling to data scarcity and complex biological processes.

Fast walking, even just 15 minutes a day, can dramatically reduce the risk of death, especially from heart disease, according to a large study involving nearly 80,000 low-income and predominantly Black Americans in the South. The findings not only affirm the well-known health benefits of walking but also highlight how pace matters and how fast walking offers a powerful, accessible tool for improving health across underserved communities.

A mysterious gut hormone may be behind many cases of chronic diarrhea, especially in people with undiagnosed bile acid malabsorption, a condition often mistaken for irritable bowel syndrome. Researchers from the University of Cambridge identified that the hormone INSL5 spikes when bile acid reaches the colon, triggering intense diarrhea. Their discovery not only sheds light on the biological cause of symptoms but opens the door to a diagnostic blood test... Read more ›

In the quest to understand how and why early humans started walking on two legs, scientists are now looking to chimpanzees living in dry, open savannah-like environments for clues. A new study reveals that these chimpanzees, despite the open terrain, still frequently climb trees to gather fruit and other foods found high in the canopy. Their behavior suggests that bipedalism may not have evolved purely as a response to ground-based... Read more ›

Scientists have cracked open a mysterious layer inside batteries, using cutting-edge 3D atomic force microscopy to capture the dynamic molecular structures at their solid-liquid interfaces. These once-invisible electrical double layers (EDLs) twist, break, and reform in response to surface irregularities phenomena never seen before in real-world battery systems. The findings don t just refine our understanding of how batteries work at the microscopic level they could fundamentally change how we... Read more ›
