Scientists just solved the 9-million-year mystery of where potatoes came from

1 August 2025 at 15:05
About 9 million years ago, a wild interspecies fling between tomato-like plants and potato relatives in South America gave rise to one of the world’s most important crops: the potato. Scientists have now traced its roots to a rare natural hybridization that created the tuber, a storage organ that allowed the plant to survive harsh Andean environments and spread rapidly.

515-mile lightning flash caught from space

1 August 2025 at 13:30
A jaw-dropping 515-mile lightning bolt lit up the skies from Texas to Kansas City, smashing previous records and reshaping our understanding of extreme weather. Thanks to advanced satellite tech, scientists like Randy Cerveny and Michael Peterson are uncovering the mechanics of "megaflash" lightning—rare, colossal discharges that span hundreds of miles across the sky. These massive bolts, emerging from long-lived, sprawling thunderstorms, pose real danger even when skies seem clear.

Rutgers physicists just discovered a strange new state of matter

1 August 2025 at 11:22
At the edge of two exotic materials, scientists have discovered a new state of matter called a "quantum liquid crystal" that behaves unlike anything we've seen before. When a conductive Weyl semimetal and a magnetic spin ice meet under a powerful magnetic field, strange and exciting quantum behavior emerges—electrons flow in odd directions and break traditional symmetry. These findings could open doors to creating ultra-sensitive quantum sensors and exploring exotic states of matter in extreme environments.

After 50 years, scientists finally catch elusive neutrinos near a reactor

1 August 2025 at 11:05
A tiny 3 kg detector has made a huge leap in neutrino science by detecting rare CEvNS interactions at a Swiss reactor. This elusive effect, long predicted and hard to measure, was captured with unprecedented clarity. The achievement could kick off a new era of compact, mobile neutrino detectors with powerful applications.

Found in the trash: A super opioid 1000x stronger than morphine

1 August 2025 at 08:55
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.

Did drunk apes help us evolve? New clues reveal why we digest alcohol so well

1 August 2025 at 08:18
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 helped shape everything from safety in the trees to social drinking rituals.

4,000-year-old teeth reveal the earliest human high — Hidden in plaque

1 August 2025 at 07:12
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.

Forget the Big Bang: Gravitational waves may have really created the Universe

A team of scientists has proposed a groundbreaking new theory on the Universe's origins, offering a fresh, radical take on the Big Bang's early moments. Unlike the widely accepted inflationary model, which involves speculative assumptions, the new model starts with the established concept of De Sitter space, aligning with dark energy observations. The scientists believe gravitational waves—ripples in space-time—were the key to seeding the formation of galaxies and cosmic structure, eliminating the need for unknown elements.

This spectrometer is smaller than a pixel, and it sees what we can’t

Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the near-infrared. The technology makes it possible to create hand-held spectroscopy devices and holds promise for the development of devices that incorporate an array of the new sensors to serve as next-generation imaging spectrometers.

Fat melts away, but so does muscle: What Ozempic users need to know

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.

Pain relief without pills? VR nature scenes trigger the brain’s healing switch

Stepping into a virtual forest or waterfall scene through VR could be the future of pain management. A new study shows that immersive virtual nature dramatically reduces pain sensitivity almost as effectively as medication. Researchers at the University of Exeter found that the more present participants felt in these 360-degree nature experiences, the stronger the pain-relieving effects. Brain scans confirmed that immersive VR scenes activated pain-modulating pathways, revealing that our brains can be coaxed into suppressing pain by simply feeling like we re in nature.

The 0.05% RNA Process That Makes Cancer Self-Destruct

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 system, killing cancer cells while sparing healthy ones. The results in animal and human cell models are so promising that drug development is now underway, potentially paving the way for more effective and less toxic treatments across multiple cancer types.
