People diagnosed with prediabetes — a condition affecting up to one in three adults depending on age — have traditionally been advised to eat healthier and shed pounds to…

Wildfires in carbon-rich tropical peatlands hit 2000-year high

A new study has found a sharp and unusual rise in wildfires in tropical peatlands during the 20th century, marking a clear departure from long-term historical patterns. Peatlands are massive underground carbon reservoirs, storing more carbon than all of the world’s forests combined. When these areas burn, they release large…

Scientists recreated a dinosaur nest to solve a 70-million-year-old mystery

How oviraptors, bird-like but flightless dinosaurs, hatched their eggs has long been unclear. Did they depend on heat from their surroundings like crocodiles, or did they warm their eggs directly like birds? A new study in Frontiers in Ecology and Evolution explores this question by examining oviraptor nesting behavior and…

Chan School of Public Health, and the Broad Institute of MIT and Harvard examined data from 131,821 participants in the Nurses’ Health Study (NHS) and Health Professionals Follow-Up Study (HPFS). The findings showed that moderate intake…

These strange pink rocks just revealed a hidden giant beneath Antarctica

Bright pink granite boulders scattered across the dark volcanic peaks of the Hudson Mountains in West Antarctica have led scientists to a remarkable discovery. Beneath Pine Island Glacier lies an enormous buried granite mass, nearly 100 km wide and 7 km thick, roughly half the size of Wales in the…

These dinosaurs had wings but couldn’t fly

Dinosaur fossils preserved with their feathers suggest that some of these animals had already lost the ability to fly. As the research team explains, “Feather molting seems like a small technical detail — but when examined in fossils, it can change everything we thought about the origins of flight, highlighting…

AI uses as much energy as Iceland but scientists aren’t worried

Artificial intelligence is often blamed for driving up energy use and worsening climate change, but new research suggests its overall impact on global emissions is surprisingly small. The findings even point to potential environmental and economic benefits as AI continues to expand. Researchers from the University of Waterloo and the…

He survived 48 hours without lungs and lived

Humans cannot survive without lungs. Yet one patient managed to live for 48 hours without them. In a report published in the Cell Press journal Med, surgeons detail how they removed a man’s severely infected lungs and used an “artificial lung” system to keep him alive until a double lung…

New drug protects liver after intestinal surgery and boosts nutrient absorption

When sections of the small intestine become diseased or die, surgeons often must remove the damaged tissue. This procedure, known as a radical small bowel resection, can save lives. However, it comes with a major downside. Many patients later develop serious liver problems, including long-term damage or even liver failure…

Even JWST can’t see through this planet’s massive haze

A newly studied exoplanet, Kepler-51d, is wrapped in an unusually dense layer of haze that may be hiding both what it is made of and how it formed. Using NASA’s James Webb Space Telescope (JWST), a team led by Penn State researchers took a closer look at this so-called “super-puff”…

AI-powered robot learns how to harvest tomatoes more efficiently

Farm labor shortages are pushing agriculture toward greater automation, especially when it comes to harvesting. But not all crops are easy for machines to handle. Tomatoes, for example, grow in clusters, which means a robot must carefully select ripe fruit while leaving unripe ones untouched. This requires precise control and…

Scientists used 7,000 GPUs to simulate a tiny quantum chip in extreme detail

Creating detailed computer models of quantum chips helps scientists predict how they will behave before manufacturing begins. This approach allows researchers to catch potential issues early and confirm that designs will perform as expected. At Berkeley Lab, Quantum Systems Accelerator (QSA) researchers Zhi Jackie Yao and Andy Nonaka from the…

Study finds ChatGPT gets science wrong more often than you think

Washington State University professor Mesut Cicek and his research team repeatedly tested ChatGPT by giving it hypotheses taken from scientific papers.
