Too much light at night may quietly reshape your heart

A study involving more than 11,000 people has found that exposure to light at night is associated with potentially harmful changes in both the structure and function of the heart. The findings were published September 9 in the European Heart Journal. The research was led by Professor Lu Qi of…

Your next prescription could be treating a side effect from the last one

A large study across Ontario has found that widely used medications, including statins and iron supplements, can sometimes trigger a chain of additional prescriptions in older adults. In these cases, a side effect from one drug may be mistaken for a new medical condition, prompting treatment with another medication. The…

Tiny nanolaser could cut computer energy use in half

The development of a nanolaser could mark an early step toward a future in which microchips communicate entirely with particles of light. Researchers at DTU have created a tiny nanolaser that could eventually help make computers, smartphones, and data centers faster while using much less energy. The breakthrough was published…

Scientists just made quantum computer operations 1,000 times faster

Quantum computers remain highly vulnerable to errors and tiny disturbances from their surroundings. The longer a quantum operation takes to complete, the more time there is for those errors to build up. Researchers at Chalmers University of Technology in Sweden have now developed a method that can perform a broad…

Wasps are disappearing this summer, and scientists are worried

Summer can be lovely – until a wasp turns up. Whether they present as an irritating picnic visitor or an uninvited loft guest, common social wasps are as much a part of our summer as festivals, sun cream and the growing despair of how to entertain children who’ve forgotten how…

Study of 1.9 million people finds a striking link between ADHD and gut problems

Researchers at the University of Warwick have found a striking association between ADHD and digestive health after analyzing data from more than 1.9 million people across 23 studies. Overall, people with ADHD were almost 50% more likely to experience gastrointestinal symptoms than people without ADHD. Some individual conditions showed even…

Physicists just found a tiny glitch in time itself

Quantum mechanics has always challenged our everyday understanding of reality. In the quantum world, particles can exist in a superposition of states, meaning they can occupy multiple possible positions or configurations at the same time. Physicists describe these possibilities mathematically using a wavefunction. That picture is very different from ordinary…

Scientists find signs of extreme aging and youth in the same 117-year-old

For roughly two centuries, human life expectancy climbed steadily as medicine, sanitation, nutrition, and healthcare improved. More recent research, however, suggests that this long upward trend may now be leveling off in developed countries. If that is the case, the next major challenge may no longer be simply preventing disease,…

Scientists discover the human heart can regrow muscle after a heart attack

Researchers from the University of Sydney, the Baird Institute and Royal Prince Alfred Hospital in Sydney have found that the human heart can produce new muscle cells after a heart attack. The discovery challenges the long-held assumption that heart muscle lost during an attack cannot regenerate and could eventually help…

Eating only 8 hours a day may help control Type 1 diabetes

A new UIC study suggests that time-restricted eating could offer a safe and potentially effective way to improve blood sugar control in adults with Type 1 diabetes. The research was led by kinesiology and nutrition professor Krista Varady, a longtime researcher in the field of intermittent fasting. “This is the…

The Moon may have formed intact just hours after a giant collision

Earth has an unusually large moon compared with other rocky planets in the solar system, but scientists still do not fully understand how it formed. A new study from researchers at the Southwest Research Institute and the University of Arizona suggests that one long-overlooked factor may have played a major…

UCLA scientists turn cord blood into powerful cancer-fighting T cells

T cell receptor therapy, known as TCR therapy, is a form of cancer treatment that genetically modifies immune cells called T cells so they can recognize and attack cancer with high precision. The approach resembles CAR T-cell therapy, but there is an important difference. CAR T-cell therapy can recognize proteins…
