Who should have a say in which species are saved? The California condor offers lessons for a global biodiversity treaty‎

In 1987, biologists captured the last free-flying condor to transfer it to captivity, and the largest flying North American bird species was officially declared extinct in the wild. Today, after decades of coordinated efforts and millions of dollars spent on captive breeding and reintroduction efforts, more than 300 condors have been restored to their natural environment.

Bell pepper colors reveal differences in sweetness, nutrients and ripeness‎

Raw, grilled, roasted, stuffed—there are many ways to enjoy bell peppers, also called capsicums, sweet peppers or paprika. Bell peppers originated in Central and South America and belong to the nightshade family along with tomatoes and eggplants.

Tests reveal why titanium additions do not fully prevent pitting corrosion in stainless steel‎

Stainless steel is widely used for its corrosion resistance, but it is not invincible. In environments containing chloride ions, such as seawater, pitting corrosion can occur. These pits often start at tiny particles called inclusions embedded in the steel.

Single X-ray pulse reveals plasma nanostructures across scales with one camera‎

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.

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 lives is inescapable. Its behavior, especially its flaring, has an impact.

'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 moment should be exactly equal and opposite to the electron's.
