Unselfish behavior has evolutionary reasons

Altruistic behavior is often seen as an exclusively human characteristic. However, behavioral research has uncovered numerous examples of altruistic behavior in the animal kingdom. In a new study, researchers at the University ...

Could artificially dimming the sun prevent ice melt?

With methods of so-called geoengineering, the climate could theoretically be artificially influenced and cooled. Bernese researchers have now investigated whether it would be possible to prevent the melting of the West Antarctic ...

First demonstration of antimatter wave interferometry

Matter waves constitute a crucial feature of quantum mechanics, in which particles have wave properties in addition to particle characteristics. This wave-particle duality was postulated in 1924 by the French physicist Louis ...

Finding vaporized metal in the air of an exoplanet

WASP-121b is an exoplanet located 850 light years from Earth, orbiting its star in less than two days—a process that takes Earth a year to complete. WASP-121b is very close to its star—about 40 times closer than Earth ...

Puzzle about nitrogen solved thanks to cometary analogs

One of the basic building blocks of life is nitrogen. An international consortium was able to detect ammonium salt containing nitrogen on the cometary surface of Chury thanks to a method using analogs for comet material. ...

Tracking down the mystery of entangled particles of light

Bernese researchers have taken an important step towards new measurement methods such as quantum spectroscopy. In an experiment, they succeeded in uncovering part of the mystery surrounding the so-called "entangled photons" ...

Long-term liquid water also on non-Earth-like planets?

Life on Earth began in the oceans. In the search for life on other planets, the potential for liquid water is therefore a key ingredient. To find it, scientists have traditionally looked for planets similar to our own. Yet, ...

Ground-breaking number of brown dwarfs discovered

Brown dwarfs, mysterious objects that straddle the line between stars and planets, are essential to our understanding of both stellar and planetary populations. However, only 40 brown dwarfs could be imaged around stars in ...
