The right order
The right order
Ingo Scholtes from the Chair of Systems Design has developed an analytical method that takes account of the chronological order of connections within networks. This not only makes it possible to more accurately identify links between topics on the internet, but also makes it easier to predict the spread of epidemics, for example.

Big issues around small particles
Big issues around small particles
An Empa team has succeeded in developing a new three-dimensional cell model of the human placental barrier. The "model organ" can quickly and reliably deliver new information on the intake of substances, such as nano-particles, by the placental barrier and on any possible toxic effects for the unborn child.

Clarifiying complex chemical processes with quantum computers
Clarifiying complex chemical processes with quantum computers
Science and the IT industry have high hopes for quantum computing, but descriptions of possible applications tend to be vague. Researchers at ETH Zurich have now come up with a concrete example that demonstrates what quantum computers will actually be able to achieve in the future. Specialists expect nothing less than a technological revolution from quantum computers, which they hope will soon allow them to solve problems that are currently too complex for classical supercomputers.

Diving into magnets
Diving into magnets
First-time 3D imaging of internal magnetic patterns Magnets are found in motors, in energy production and in data storage. A deeper understanding of the basic properties of magnetic materials could therefore impact our everyday technology. A study by Scientists at the Paul Scherrer Institute PSI in Switzerland, the ETH Zurich and the University of Glasgow has the potential to further this understanding.

New catalyst for future energy storage
New catalyst for future energy storage
In order to allow solar and wind energy to make a greater contribution to our future energy supply, it must be possible to store this energy efficiently, for instance in the form of hydrogen. This is done by means of the electrical cleavage of water in an electrolyser. Thanks to a new catalyst material developed by researchers at the Paul Scherrer Institute (PSI) and Empa, the Swiss Federal Laboratories for Materials Science and Technology, this process may become cheaper and more efficient in the future.

Nanomaterial helps store solar energy: efficiently and inexpensively
Nanomaterial helps store solar energy: efficiently and inexpensively
Field trials show that new catalyst material for electrolysers is reliable Efficient storage technologies are necessary if solar and wind energy is to help satisfy increased energy demands. One important approach is storage in the form of hydrogen extracted from water using solar or wind energy. This process takes place in a so-called electrolyser.

Nano particles as food additives: improving risk assessment
Nano particles as food additives: improving risk assessment
The anticaking agent E551 silicon dioxide, or silica, has been used widely in the food industry over the past 50 years, and was long thought to be quite safe. Now, however, researchers working on the National Research Programme ‘Opportunities and Risks of Nanomaterials' have discovered that these nanoparticles can affect the immune system of the digestive tract.

A 100-year-old physics problem has been solved at EPFL
A 100-year-old physics problem has been solved at EPFL
EPFL researchers have found a way around what was considered a fundamental limitation of physics for over 100 years. They were able to conceive resonant systems that can store electromagnetic waves over a long period of time while maintaining a broad bandwidth. At EPFL, researchers challenge a fundamental law and discover that more electromagnetic energy can be stored in wave-guiding systems than previously thought.

Injector 2: a pre-accelerator for protons
As fundamental building blocks of matter, protons are a part of all things that surround us. At the Paul Scherrer Institute PSI, however, they step out of their usual role and are deployed to generate other particles, namely neutrons and muons, which are subsequently used to study materials.

Water temperatures to drop after the Mühleberg plant closes
Water temperatures to drop after the Mühleberg plant closes
Mühleberg is the first Swiss nuclear power plant slated for decommissioning in 2019. EPFL researchers have shown that its shutdown will lower water temperatures in the Aar River and Lake Biel, and could affect waterways as far away as Germany. When the Mühleberg nuclear power station goes offline in 2019, the waters of the Aar River and Lake Biel will cool down.
