Protecting ecosystems with ecological theory
Protecting ecosystems with ecological theory
Ecosystems respond sometimes very differently to human impacts. However, it is still poorly understood what causes these differences. A team of researchers from Eawag and WSL is now proposing an integrative approach based on four fundamental processes shaping biodiversity on land and in water. The approach provides guidance for how biodiversity in blue (water) and green (land) ecosystems can be better protected.

Placebo reduces feelings of guilt
Guilt is an uncomfortable feeling and can be burdensome. Researchers at the University of Basel have shown that placebos can help reduce feelings of guilt, even when the placebo is administered openly. People don't always behave impeccably in relationship to others. When we notice that this has inadvertently caused harm, we often feel guilty.

Integrated photonic circuits could help close the 'terahertz gap'
Researchers have collaborated with those at Harvard and ETH Zurich on a new thin-film circuit that, when connected to a laser beam, produces finely tailorable terahertz-frequency waves. The device opens up a world of potential applications in optics and telecommunications. Researchers led by Cristina Benea-Chelmus in the Laboratory of Hybrid Photonics ( HYLAB ) in EPFL's School of Engineering have taken a big step toward successfully exploiting the so-called terahertz gap, which lies between about 300-30,000 gigahertz (0.3 to 30 THz) on the electromagnetic spectrum.

How grasses avoid inbreeding
How grasses avoid inbreeding
Researchers have been able to show which genes inhibit self-fertilisation in grasses. Plant scientists can now use this mechanism in a more targeted way to breed new varieties of forage grasses as well as rice or barley. 'This breakthrough was enabled by technological advances in genome analysis. It's only in recent years that these have made it possible to efficiently sequence the entire genome of an individual organism.' Studer has devoted over 15 years to this subject, together with collaborators from Denmark, Wales and the USA.

How fungi promote bacterial diversity
How fungi promote bacterial diversity
In theory, the genetic diversity of populations should decrease as they expand across space. But this is not true for bacteria. Researchers at Eawag are now showing that fungi play an important role in this context. They make it easier for bacteria to spread and thus also promote genetic exchange between different bacteria.

How to turn a tentacle into a foot
How to turn a tentacle into a foot
By identifying a key regulator of cell identity, a team from the University of Geneva and the FMI has succeeded in modifying the structure and function of tentacle cells in hydra. Humans, animals, plants: all multicellular organisms are made up of specialized cells called differentiated cells. Thus, the cells that make up the epidermis do not have the same identity - nor the same function - as those that line the digestive system, for example.
