Smelling chocolate helped men complete more reps without feeling more tired
Simply smelling chocolate helped men complete more leg extension repetitions without making the workout feel harder, with dark chocolate producing the strongest effect. The researchers think familiar food aromas may influence appetite and motivation by making the brain anticipate eating.
This Australian cave hid 25,000 years of ritual secrets
Microscopic plant remains are revealing how GunaiKurnai ancestors used Cloggs Cave for ritual practices over thousands of years. People deliberately gathered whole grasses, carried them into the dark cave, and burned them in thin layers, leaving behind traces that may span 25,000 years. A standing stone erected around 2,000 years ago and other ritual objects strengthen the evidence that the cave was a long-lived spiritual site.
Scientists discover a major brain shift between ages 50 and 75
Scientists have uncovered sweeping changes in how the human brain controls and organizes its genome beginning in midlife, offering new clues to why aging sharply increases the risk of Alzheimer’s and other neurodegenerative diseases. One of the biggest shifts occurred between about ages 50 and 75, when many of the brain’s original immune cells declined and were replaced by cells with more inflammatory characteristics. Researchers also found weakening of cells that help maintain the blood-brain b
UV light reveals possible camouflage on a 125-million-year-old crocodile
A 125-million-year-old crocodile fossil has revealed preserved skin, possible sensory organs, sophisticated respiratory structures, and an unexpected pattern on its tail. Ultraviolet light exposed alternating bands that may represent ancient camouflage, potentially preserving the oldest known coloration in a crocodylomorph.
The shape behind the Einstein problem just revealed strange new physics
A mathematical shape famous for covering a surface without ever repeating has revealed an unexpected ability to twist light into unusual chiral patterns. The discovery could lead to new ways of controlling light, polarization, and advanced optical devices.
Supermassive black hole winds are 100 times more powerful than scientists thought
Astronomers have discovered that winds from a supermassive black hole are about 100 times more powerful than previously thought. XRISM observations showed the resulting turbulence spreading roughly 300,000 light-years, extending far beyond the black hole’s host galaxy. The energy involved rivals several billion supernova explosions, revealing just how dramatically black holes can influence the space around them.
Nearly 10,000 patients reveal what works best for knee arthritis pain relief
A major analysis of 139 clinical trials involving nearly 10,000 people suggests that some of the simplest treatments may work best for knee osteoarthritis. Knee braces ranked highest overall for reducing pain, stiffness, and mobility problems, while water-based therapy was especially effective for pain and regular exercise consistently improved both pain and physical function. More high-tech approaches, including ultrasound, generally performed worse.
Plague was killing entire families thousands of years before the Black Death
Ancient DNA reveals that plague was already killing hunter-gatherers in Siberia 5,500 years ago, long before cities and flea-driven epidemics. The prehistoric strains may have been especially dangerous because they carried a genetic factor capable of provoking severe immune reactions.
Cancer is rising in younger adults. Faster biological aging may help explain why
Cancer rates are rising in adults under 55, and new research suggests accelerated biological aging may be one piece of the puzzle. Scientists found that people from more recent generations tended to have bodies that appeared biologically older than those of earlier generations at the same chronological age. Greater biological age acceleration was linked to a higher risk of early onset cancers, with specific patterns seen for lung, gastrointestinal, uterine and colorectal cancers.
Chemistry textbooks have been getting this wrong for nearly 100 years
A foundational chemistry concept found in textbooks for almost 100 years may have been taught incorrectly. Researchers say the inductive effect in neutral molecules appears to extend only across one chemical bond, rather than gradually weakening over three or four bonds as traditionally taught. The team argues that updating this explanation could make organic chemistry easier to understand and provide a stronger foundation for future research and innovation.
Hidden brain wiring may help keep the mind sharp as gray matter shrinks
Scientists have discovered that the brain’s short-range wiring may help protect cognition even as gray matter shrinks with age. Healthier connections just beneath the brain’s surface were linked to better language skills and appeared to weaken the impact of gray matter loss.
This German submarine sank in 1917. It’s still leaking TNT
A World War I submarine wreck off Denmark is leaking TNT into the surrounding water, seabed, and marine life more than a century after it sank. Scientists warn that thousands of similar wrecks could pose growing environmental risks as they continue to corrode.
