Medical Xpress / How natural daylight can help people with diabetes improve blood sugar levels
People with type 2 diabetes may be able to improve their blood sugar by doing something as simple as sitting by a window for a few hours each day. In a study published in Cell Metabolism, scientists showed that natural daylight ...
Phys.org / Scientists who use AI tools are publishing more papers than ever before
Science is entering a massive publishing boom, in large part due to artificial intelligence. New research published in the journal Science has revealed that scientists who use large language models (LLMs) like ChatGPT are ...
Tech Xplore / AI's 2025 carbon footprint may match New York City, report estimates
By the end of the year, the carbon footprint of global AI systems for the whole of 2025 could equal that of New York City. At the same time, AI's thirst for water could rival that of the world's bottled water market, according ...
Phys.org / Scientists build a quantum computer that can repair itself using recycled atoms
Like their conventional counterparts, quantum computers can also break down. They can sometimes lose the atoms they manipulate to function, which can stop calculations dead in their tracks. But scientists at the US-based ...
Phys.org / Ancient hunter-gatherer DNA may explain why some people live to 100 years or more
Our hunter-gatherer ancestors have given us many things. They passed down mastery of fire for cooking and early survival technologies, such as stone tools. They may also have given us the secret to a long life. A new study ...
Phys.org / How a new diet of penguins is changing puma behavior and social lives in Patagonia
Penguins in the coastal steppes of Argentina have a new enemy to worry about: the increasing numbers of pumas in Monte León National Park (MLNP). These powerful mountain cats were once on the brink of disappearing from this ...
Phys.org / A universal law could explain how large trades change stock prices
Financial markets are often seen as chaotic and unpredictable. Every day, traders around the world buy shares and sell assets in a whirlwind of activity. It looks like a system of total randomness—but is it really?
Phys.org / A new global map uses a fleet of satellites to catch methane leaks from the energy sector
When it comes to global warming and greenhouse gases, methane is one of the bad guys. It's the second most important contributor to climate change after carbon dioxide. However, quantifying the exact amount being released ...
Phys.org / Massive rock layer beneath Bermuda may explain island's unusual elevation
Bermuda may well be associated with exaggerated stories of missing ships and planes, but there is another mystery about this part of the Atlantic that has been puzzling scientists for decades: Why does the island appear to ...
Tech Xplore / Sub-millimeter-sized robots can sense, 'think' and act on their own
Robots small enough to travel autonomously through the human body to repair damaged sites may seem the stuff of science fiction dreams. But this vision of surgery on a microscale is a step closer to reality, with news that ...
Phys.org / Supernova immersion model suggests Earth-like planets are more common in the universe
Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a nearby supernova (the massive ...
Phys.org / Misinformation is an inevitable biological reality across nature, researchers argue
From claims that vaccines don't work to manipulated images and deliberately misrepresenting what politicians say, social media is often rife with misinformation. But far from being a recent phenomenon, there is nothing new ...
Medical Xpress / How a simple slipknot can help surgeons tie the perfect suture
In surgical procedures, the last knot of a suture is crucial because it must hold the wound firmly in place to allow proper healing. But many surgeons struggle to apply the perfect tension. Tie it too tightly, and it can ...
Phys.org / A new species of tiny orange frog discovered in Brazil's cloud forests
Despite the vast numbers of animal species already identified, the natural world is still capable of springing a few surprises. Deep in the cloud forests of the Serra do Quiriri mountain range in the southern Brazilian Atlantic ...
Phys.org / Searchable Bronze Age site database could help answer key questions about ancient Anatolia
To boost our understanding of a little-known civilization that thrived more than 3,000 years ago, scientists have built an easy-to-use digital catalog of 483 Bronze Age sites in western Anatolia.
