Phys.org / Bell-bottoms today, miniskirts tomorrow: Math reveals fashion's 20-year cycle
Fashion insiders and beauty magazines have long cited the "20-year-rule"—the idea that clothing trends often resurface every two decades. According to Northwestern University scientists, that observation isn't just anecdotal. ...
Tech Xplore / Wind-powered robot could enable long-term exploration of hostile environments
Researchers at Cranfield University have created WANDER-bot, a low-cost, 3D-printed robot that is powered by wind energy. Designed to spend long durations in hostile, windy environments such as certain deserts, polar regions ...
Phys.org / New ice core studies expand histories of greenhouse gases and ocean temperature to 3 million years
New analyses of ancient ice from Antarctica and the air contained inside it are extending the history of Earth's climate records and expanding researchers' understanding of how the planet has changed over the last 3 million ...
Medical Xpress / Study offers single explanation for two major symptoms of schizophrenia
Scientists have long known that dopamine helps the brain learn from rewards, but a new computational model shows how for people with schizophrenia this learning system can break down and simultaneously produce two very different ...
Medical Xpress / The Alzheimer's gut-brain link: How butyrate could curb amyloid-β buildup and inflammation
Alzheimer's disease (AD) is a neurodegenerative disease that causes progressive memory loss and a significant decline in mental functions. Past studies have shown that people with AD exhibit a buildup of a protein called ...
Phys.org / ISS study identifies thresholds for muscle atrophy and fiber changes in reduced gravity
It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold needed to maintain sufficient ...
Phys.org / Bull sharks form social relationships with specific 'friends,' research reveals
Sharks are often viewed as solitary, but a new study—carried out on the Shark Reef Marine Reserve in Fiji—has found that rather than mixing at random, bull sharks have "active social preferences" and choose their social ...
Phys.org / Drought hits gulf fisheries, sparking food security fears
A severe and prolonged U.S. drought in the late 1980s played a central role in one of the largest fisheries declines ever recorded in the Gulf of Mexico, according to a new study published in Nature Communications.
Phys.org / New study shows democracy has deep global roots—not just Greece and Rome
A new study on ancient societies from around the world is rewriting what we thought we knew about democracy. A team of researchers analyzed archaeological and historical evidence from 31 ancient societies across Europe, Asia, ...
Phys.org / How two dim stars came together to shine brightly
Brown dwarfs get a bad rap in the stellar world, often labeled as "failed stars" for their inability to sustain nuclear fusion at their cores. The mass of these objects falls between planets and stars, ranging from 13 to ...
Phys.org / Scientists discover new heavy proton-like particle at CERN
Scientists from the University of Manchester have played a leading role in the discovery of a new subatomic particle at CERN's Large Hadron Collider (LHC). The particle, known as the Ξcc⁺ (Xi‑cc‑plus), is a new type ...
Phys.org / Dolls beat tablets at building social understanding, six-week study suggests
Research by Cardiff University has found that playing with Barbie dolls can help reach key milestones in developing empathy and social understanding during childhood. Doll play was found to be beneficial for both boys and ...
