Black holes may spit out nearly as much matter as they swallow

Astronomers led by the University of Warwick have uncovered what they describe as a kind of cosmic digestive system around a black hole. Their observations show that even when a black hole appears faint, it may still be actively expelling large amounts of matter rather than simply swallowing everything nearby.…

AI can tell if your brain is aging faster than you are

A new machine-learning approach that examines brain activity during sleep may help identify people with an elevated risk of developing dementia. The research was led by scientists at UC San Francisco and Beth Israel Deaconess Medical Center in Boston. The system estimates a person’s “brain age” by analyzing electrical signals…

Strange gamma rays could reveal how stars forge heavy elements

Researchers led by scientists at the Facility for Rare Isotope Beams, or FRIB, have identified the source of a puzzling abundance of low-energy gamma rays released by the zinc-70 nucleus. Their results show that magnetic transitions occurring inside the nucleus produce the unexpected signal. The findings, published in Nature in…

This new alloy is up to 10 times stronger than steel and surprisingly flexible

Materials scientists can now reshape the internal structure of certain alloys at extremely small scales, allowing them to enhance properties such as strength, durability, and flexibility. One especially promising group of materials is known as intermetallics. Intermetallics are solid materials made from two or more metallic elements arranged in a…

A strange quantum rule caps electrical resistance

Experimental atomic physicists have found that electrical resistance caused by particle collisions appears to have a maximum limit. Researchers from the University of Toronto, L’École Normale Supérieure in Paris and Lehigh University in Pennsylvania reached the finding by studying ultracold potassium atoms cooled to nearly absolute zero. As the scientists…

Scientists discover how obesity may fuel Alzheimer’s disease

A growing body of research suggests that Alzheimer’s disease may be influenced by biological changes occurring far beyond the brain. New findings now point to metabolic health, especially obesity, as a possible contributor to processes that worsen the disease. The study, led by Houston Methodist researchers, examined how changes in…

Scientists find a simple routine linked to less pain and depression

A consistent daily routine may offer meaningful benefits for both physical and mental health, according to new research from the University of Missouri. The study found that older adults who followed regular daily schedules reported less physical pain and fewer symptoms of depression, including those who experienced insomnia. The findings…
