An alternative way to manipulate quantum states
An alternative way to manipulate quantum states
Researchers at ETH Zurich have shown that quantum states of single electron spins can be controlled by currents of electrons whose spins are evenly aligned. In the future, this method could be used in electronic circuit elements. Electrons have an intrinsic angular momentum, the so-called spin, which means that they can align themselves along a magnetic field, much like a compass needle.

Chemists, biologists, archaeologists - who will unearth the recipes of our ancestors?
Chemists, biologists, archaeologists - who will unearth the recipes of our ancestors?
Thanks to a new multidisciplinary approach, a team from the University of Geneva and the CNRS has traced the dietary practices of a Senegalese village. This method will be used for other archaeological digs. Food is more than just a biological need. A veritable marker of culture and identity, it encompasses a wide range of practices that allow us to "read" a region, a country or a social group.

Reaction of trees to heat unravelled
Reaction of trees to heat unravelled
At temperatures above 30°C, water loss through transpiration increases in trees, while CO2 uptake decreases - even when there is enough CO2 in the atmosphere. Researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL were able to show this in a study conducted using a new high-tech facility.

New approach in the synthesis of complex natural substances
New approach in the synthesis of complex natural substances
They are found as fragrances in cosmetics or as flavorings in food, and form the basis of new medications: Terpenes are natural substances that occur in plants, insects and sea sponges. They are difficult to produce synthetically. However, chemists at the University of Basel are now introducing a new method of synthesis.

A new anticoagulant with no risk of bleeding
A new anticoagulant with no risk of bleeding
A team from the University of Geneva, in collaboration with the University of Sydney, has developed a new type of anticoagulant whose action can be rapidly stopped. Anticoagulant treatments are crucial for managing many conditions, such as heart disease, stroke and venous thrombosis. Current options, however, carry an inherent risk of serious bleeding due to trauma or unforeseen events.
