Hidden dimensions could explain where mass comes from

The geometry of space itself may play a far more central role in physics than previously thought. Instead of serving only as the backdrop where forces act, spacetime may be responsible for the forces and particles that make up the universe. New theoretical work suggests that the fundamental behavior of…

AI found a way to stop a virus before it enters cells

New study shows some plant-based diets may raise heart disease risk

Previous studies have indicated that eating large amounts of ultra-processed foods[1] is linked with a higher likelihood of developing cardiovascular diseases. Other research[2] has found that diets centered on plant-based foods can lower this risk when those foods offer balanced nutrition and are consumed in appropriate proportions. To explore how…

Anxiety and insomnia linked to sharp drops in key immune cells

Natural killer (NK) cells act as key defenders within the immune system. They help control infections by targeting invading microbes, foreign materials, and damaged or infected cells early on, which limits their ability to spread. NK cells travel through the bloodstream (circulatory) or remain in specific tissues and organs. When…

New orbital clue reveals how hot Jupiters really formed

The first exoplanet ever confirmed in 1995 turned out to be what researchers now describe as a “hot Jupiter,” a giant world similar in mass to Jupiter but orbiting its star in only a few days. Scientists now think these planets originally formed far from their host stars, similar to…

Light-printed electrodes turn skin and clothing into sensors

Researchers at Linköping and Lund universities in Sweden have demonstrated that visible light can be used to form electrodes from conductive plastics without the need for dangerous chemicals. Their results show that these electrodes can be produced on a wide variety of surfaces, creating opportunities for new types of electronics…

Cannabis compounds show unexpected power against ovarian cancer

In the future, medications derived from cannabis may play a role in treating ovarian cancer.
