Scientists studying 1,300 golden retrievers have uncovered genetic clues explaining why some dogs are more anxious, energetic, or aggressive than others. Remarkably, several of the same genes linked to canine behavior are also tied to human traits like anxiety, depression, and intelligence. The discovery suggests dogs and humans share biological roots for emotions and behavior. Understanding these links could help owners better interpret their pets’ reactions and even improve training... Read more ›

Popular acid reflux drugs such as Prilosec, Nexium, and Protonix may carry hidden risks when taken long term. A new study found that extended use disrupted iron and calcium levels in rats, changes associated with anemia and osteoporosis risk. Researchers also observed shifts in mineral balance across multiple organs. Experts say the medications are effective, but prolonged use without medical guidance could have unintended consequences.

“Forever chemicals” known as PFAS have quietly infiltrated everything from nonstick pans to food packaging—and now new research suggests some of them may be speeding up the aging process itself. In a nationally representative U.S. study, two lesser-known PFAS compounds, PFNA and PFOSA, were found in 95% of participants and strongly linked to faster biological aging in men aged 50 to 64.

Avoiding meat might slightly lower the odds of reaching 100 — but only for frail, underweight seniors. In very old age, staying strong and maintaining muscle matters more than long-term disease prevention. Older adults who included fish, eggs, or dairy were just as likely to become centenarians as meat eaters, suggesting that key nutrients may make the difference. The takeaway: nutrition needs change dramatically with age. Read more ›

A shingles shot might do more than prevent a painful rash — it could actually help slow down the aging process. In a large national study of more than 3,800 Americans age 70 and older, those who received the shingles vaccine showed slower biological aging compared to those who didn’t. Researchers found lower levels of chronic inflammation and slower changes in gene activity linked to aging, suggesting the vaccine may... Read more ›

A sweeping new analysis of the evidence suggests that exercise therapy — long promoted as a first-line treatment for osteoarthritis — may offer only small and short-lived relief, and in some cases might be no better than doing nothing at all. After reviewing dozens of clinical trials involving more than 13,000 participants, researchers found that benefits for knee osteoarthritis pain were minimal and tended to shrink in larger or longer-term...

Eating nothing but oatmeal for just two days might sound extreme, but it delivered a striking payoff in a new clinical trial. People with metabolic syndrome who followed a short, calorie-reduced oat-based plan saw their harmful LDL cholesterol drop by 10%, along with modest weight loss and lower blood pressure. Even more surprising, the cholesterol benefits were still visible six weeks later. Read more ›

Scientists have zeroed in on a critical weak spot behind a rare but devastating brain autoimmune disorder often known as “Brain on Fire.” The disease strikes when the immune system attacks NMDA receptors—key molecules involved in memory and thinking—leading to psychiatric symptoms, seizures, and even death.

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half the size of continental Europe since 2014. Even more striking, a region southwest of Africa has begun weakening even faster in recent years, hinting at unusual activity deep within Earth’s molten outer core. Read more ›

Mars’ frozen ice caps may be time capsules for ancient life. Lab experiments show that key building blocks of proteins can survive tens of millions of years in pure ice, even under relentless cosmic radiation. Ice mixed with Martian-like soil, however, destroys organic material far more quickly. The findings point future missions toward drilling into clean, buried ice rather than studying rocks or dirt.

A gel-like sugar coating on immune cells has been found to play a starring role in psoriasis. Researchers discovered that immune cells shed this outer layer to help them exit the bloodstream and enter inflamed skin. This challenges the long-held idea that only blood vessel walls changed during this process. The finding could help guide new therapies aimed at controlling harmful inflammation. Read more ›

Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly adjusting the mix of tellurium and selenium in ultra-thin films. That tiny chemical tweak changes how electrons interact, effectively turning a quantum phase “dial” until the ideal state appears. The result is a more practical path toward building stable, next-generation quantum devices. Read more ›

A lost cache of 250-million-year-old fossils from Australia has rewritten part of the story of life after Earth’s worst mass extinction. Instead of a single marine amphibian species, researchers uncovered evidence of a surprisingly diverse community of early ocean predators. One of these creatures had relatives stretching from the Arctic to Madagascar, showing that some of the first sea-going tetrapods spread across the globe with remarkable speed. Read more ›

A weeklong, high-intensity version of TMS may work nearly as well as the standard six-week treatment for depression. In a UCLA study, patients who received five sessions a day for five days experienced meaningful symptom relief comparable to those on the traditional schedule. Some who didn’t improve immediately showed strong gains weeks later. The findings hint at a faster, more accessible path to recovery. Read more ›

Horses have a vocal trick no one fully understood until now. Scientists have discovered that when a horse whinnies, it produces two completely different sounds at the same time. One is a deep tone created by vibrating the vocal folds, similar to how humans sing. The other is a high-pitched whistle generated inside the larynx, something never before confirmed in a large mammal. This rare ability, known as biphonation, likely... Read more ›

Researchers have detected microplastics in nearly all prostate cancer tumors examined in a new study. Tumor tissue contained about 2.5 times more plastic than nearby healthy prostate tissue. Scientists say this is the first Western study to directly measure plastic particles in prostate tumors. More research is needed, but the findings suggest microplastic exposure could play a role in cancer development. Read more ›

More than 40,000 years ago, Ice Age humans were carving repeated patterns of dots, lines, and crosses into tools and small ivory figurines. A new computational study of more than 3,000 of these Paleolithic signs reveals that they were not random decorations but structured sequences with measurable complexity. Surprisingly, their information density rivals that of proto-cuneiform, the earliest known writing system that emerged around 3,000 B.C.E. Read more ›

After nearly 50 years of failed attempts and scientific speculation, chemists at Saarland University have achieved what many thought might be impossible: creating a long-sought silicon-based aromatic molecule. By replacing carbon atoms in a famously stable ring-shaped compound with silicon, the team synthesized pentasilacyclopentadienide — a breakthrough published in Science. Read more ›

Subtle changes in brain blood flow and oxygen use are closely linked to hallmark signs of Alzheimer’s, including amyloid plaques and memory-related brain shrinkage. Simple, noninvasive scans may one day help spot risk earlier—by looking at the brain’s vascular health, not just its plaques. Read more ›

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, revealing surprising twists in how it flows through our galaxy. Read more ›

Scientists have proposed a surprising connection between solar flares and earthquakes. When solar activity disturbs the ionosphere, it may generate electric fields that penetrate fragile fracture zones in Earth’s crust. If a fault is already critically stressed, this extra electrostatic pressure could help trigger a quake. The idea doesn’t claim direct causation, but it offers a fresh way to think about how space weather and seismic events might interact. Read more ›
