Understanding instabilities and turbulence in plasmas is one of the key challenges across a wide range of plasma research fields, including nuclear fusion, astrophysics and laser-plasma physics. In plasmas, slight disturbances can grow due to instabilities, and energy is transferred between structures of various sizes due to turbulence. These phenomena give rise to structures ranging from very small to large, which significantly influence the overall motion and energy flow of the plasma.

Birds are more afraid of women than men. Scientists have no idea why

Scientists have uncovered a strange pattern in urban bird behavior: Across five European countries and 37 species, birds consistently fled sooner when approached by women than men. Researchers have no clear explanation for the difference, raising intriguing questions about how bi

How flare ribbons reveal hidden solar explosions on the sun

Many topics in astronomy and astrophysics are esoteric. There's not much of a relationship between something like the supermassive black hole at the center of the Milky Way and the life of a regular person going about their business. But the sun is different. Its presence in our

'One-positron cyclotron' could test a key prediction of the Standard Model

The positron is the antimatter counterpart of the electron, identical in mass but carrying an equal and opposite electric charge. Like the electron, it also behaves like a tiny bar magnet, and according to a key prediction of the Standard Model of particle physics, its magnetic m

Newly identified protein pathway helps HIV stay hidden despite treatment

Current HIV medicines are effective at suppressing the virus in the blood. However, HIV can remain "asleep" or dormant inside certain immune cells and in the brain. These hidden pockets of virus, called HIV reservoirs, are the main reason HIV cannot be cured with today's treatmen
