Nighttime light exposure was linked to thicker, stiffer heart chambers and early signs of reduced heart function in a study of more than 11,000 people. The findings suggest that keeping bedrooms darker could be an overlooked strategy for protecting the heart.
On a sunny spring day at Penn State, Cristin Millett, professor of art in the College of Arts and Architecture's School of Visual Arts, inserted a catheter needle into the umbilical vein of a placenta.
A major Ontario study found 24 common medication chains in which one drug’s side effects can be mistaken for a new medical problem, leading to another prescription. Researchers say closer medication reviews, pharmacist involvement, and automated alerts could help prevent these potentially harmful prescribing cascades.
Scientists have created an ultra-small nanolaser that could eventually allow microchips to transmit information with light instead of electricity, potentially making computers faster while cutting energy use roughly in half. Thousands of the lasers could fit on a single chip, opening possibilities for more efficient data centers, smartphones, and advanced medical sensors.
Artificial intelligence (AI) isn't yet causing widespread job losses in Australia. But with some high-profile business leaders still predicting a looming unemployment "crisis," it's little wonder many people fear AI is coming for their job.
About 252 million years ago, at the end of the Permian Period, a large proportion of species on Earth rapidly became extinct. After this mass extinction, many groups of organisms began to recover, while reptiles known as archosauromorphs—the group that includes dinosaurs and crocodiles—proliferated.
Researchers have found a way to perform certain quantum operations more than 1,000 times faster, cutting thousands of repeated control cycles down to just one. The advance could reduce errors and bring reliable, fault-tolerant quantum computers closer to reality.
As we reflect on the 25 years since the 9/11 terrorist attacks that killed almost 3,000 people, terrorism remains an ongoing yet evolving threat that defies easy answers.
Britain’s wasps have become mysteriously scarce this summer, and scientists suspect an unusual combination of temperature swings, heatwaves, and food shortages may be responsible. Even the wasps that remain appear unusually small, potentially offering a glimpse of how extreme heat could reshape insect populations.
Researchers analyzing data from more than 1.9 million people found that ADHD is associated with substantially higher rates of digestive problems. People with ADHD had nearly double the odds of constipation, 58% higher odds of irritable bowel syndrome, and more than four times the odds of encopresis.
Industrialized countries send millions of metric tonnes of used clothing, electronic equipment and other products to the Global South, along with the environmental and health costs tied to producing, consuming and disposing of those goods.
Saccharina latissima, or sugar kelp, is one of the dominant species in Maine's kelp forests, providing food, habitat and clean water to support a rich marine ecosystem. It is also the bedrock of the state's burgeoning kelp aquaculture industry, which relies on the annual harvest of reproductive tissue from the wild.
