Trial participants who received an increased weekly dose of Wegovy lost 19 per cent of their body weight in a year on average, but also saw a higher risk of painful skin sensations and nausea
School meals, provided for free by governments around the world, could be used to curb global hunger and promote a sustainable global food system, finds a new study by UCL (University College London) researchers.
Scientists announced Wednesday they have discovered the oldest-known member of the lizard family in southwest England, a tiny creature that used its surprisingly large teeth to hunt cockroaches 242 million years ago.
In the search for habitable exoplanets, atmospheric conditions play a key role in determining if a planet can sustain liquid water. Suitable candidates often sit in the "Goldilocks zone," a distance that is neither too close nor too far from their host star to allow liquid
Bacteria have long been a key source of lifesaving antibiotics, but most species cannot be grown in the lab—leaving their therapeutic potential untapped even as multidrug resistance becomes an increasingly urgent threat.
A new study co-authored by Texas A&M University geologist Dr. Michael Tice has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA's Perseverance rover.
By analyzing tooth enamel chemistry, scientists uncovered proof that Jurassic dinosaurs divided up their meals in surprising ways—some choosing buds and leaves, others woody bark, and still others a mixed menu. This dietary diversity helped massive plant-eaters coexist, while
When the JWST finally began its long-awaited science operations in July 2022, there was a long list of targets awaiting its attention. Scientists compete for observing time by submitting proposals, and for every nine submitted proposals, only one gets approved. In the most
Sweetpotato, a critical food crop for millions, has finally had its genetic code fully decoded after decades of mystery. Scientists unraveled its extraordinarily complex genome of six chromosome sets, revealing a hybrid origin stitched together from multiple wild ancestors.
On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to reach us at the speed of light—but it was not made of light. It was a different
GLP-1 drugs like Ozempic have transformed weight loss in the U.S., with nearly 12% of Americans having tried them, according to a new RAND report. Usage is especially high among women aged 50 to 64, while men catch up in older groups. Despite effectiveness, side effects like
Scientists in Korea have engineered magnetic nanohelices that can control electron spin with extraordinary precision at room temperature. By combining structural chirality and magnetism, these nanoscale helices can filter spins without complex circuitry or cooling. The
Researchers at UBC have found a way to mimic the elusive Schwinger effect using superfluid helium, where vortex pairs appear out of thin films instead of electron-positron pairs in a vacuum. Their work not only offers a cosmic laboratory for otherwise unreachable phenomena, but
Electronic devices lose energy as heat due to the movement of electrons. Now, a breakthrough in nanoengineering has produced a new kind of switch that matches the performance of the best traditional designs while pushing beyond the power-consumption limits of modern electronics.
Billions of years ago, Mars may not have been the frozen desert we see today. New simulations suggest that volcanic eruptions pumped out reactive sulfur gases, creating greenhouse effects strong enough to trap warmth and possibly liquid water. This strange sulfur-rich chemistry
For the third year running toxic blue-green algae blooms that look like pea soup and smell like rotten eggs have covered much of Lough Neagh, the largest lake in the UK and Ireland.
Archeologists studying ancient civilizations in northern Iraq during the 1930s also befriended the nearby Yazidi community, documenting their daily lives in photographs that were rediscovered after the Islamic State militant group devastated the tiny religious minority.
Astronomers using the James Webb Space Telescope have uncovered mysterious “little red dots” that may not be galaxies at all, but a whole new type of object: black hole stars. These fiery spheres, powered by ravenous black holes at their core, could explain how supermassive
Chronic insomnia may do more than leave you groggy, it could speed up brain aging. A large Mayo Clinic study found that people with long-term sleep troubles were 40% more likely to develop dementia or cognitive impairment, with brain scans showing changes linked to Alzheimer’s.
Researchers trained AI on tens of thousands of eye scans, enabling doctors to predict which keratoconus patients need early treatment and which can be safely monitored, cutting down on unnecessary procedures while preventing vision loss.
A massive Danish study reveals that despite the remarkable weight-loss benefits of semaglutide, more than half of adults without diabetes stop using it within a year. High costs, unpleasant side effects, and underlying medical or psychiatric conditions play major roles in the
