How to find signs of life in space

Astrophysicists of the University of Bern, Switzerland, contributed to a series of NASA papers that lay out strategies to search for signs of life beyond our solar system. They assume that the detection of atmospheric signatures ...

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" ...

The path to success for fish sperm

In many animals, males pursue alternative tactics when competing for the fertilization of eggs. Some cichlid fishes from Lake Tanganyika breed in empty snail shells, which may select for extremely divergent mating tactics. ...

Study details the history of Saturn's small inner moons

The small inner moons of Saturn look like giant ravioli and spaetzle. Their spectacular shape has been revealed by the Cassini spacecraft. For the first time, researchers of the University of Bern show how these moons were ...

Dicer-like enzymes with sequence cleavage preferences

Researchers keep discovering new functions of small RNAs. For instance, they can be used as a defense mechanism against viruses or self-replicating genome invaders. These tiny pieces of RNA are often produced by a cleavage ...

Explaining rare plant species

Rare plant species suffer more from disease than common species. The fact that rare species are more susceptible to attack by micro-organisms living in the soil, such as fungi and bacteria, may in fact be one of the reasons ...

Comet Chury's late birth

Comets which consist of two parts, like Chury, can form after a catastrophic collision of larger bodies. Such collisions may have taken place in a later phase of our solar system, which suggests that Chury can be much younger ...

New weakness discovered in sleeping sickness pathogen

Trypanosomes are single-celled parasites that cause diseases such as human African sleeping sickness and Nagana in animals. But they are also used in basic research as a model system to study fundamental biological questions. ...

Evolution of Alpine landscape recorded by sedimentary rocks

Rock avalanches and torrents started to form V-shaped valleys in the Swiss Alps approximately 25 million years ago. This landscape contrasts to the flat and hilly scenery, which characterized the Alps a few millions of years ...

Searching for distant worlds with a flying telescope

Researchers from the University of Bern, using an observatory on board a jumbo jet, have observed how the extrasolar Planet GJ 1214b is passing in front of its star, causing a kind of mini-eclipse. The first measurements ...
