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.

The genetics of severe illness in children with the common cold
The genetics of severe illness in children with the common cold
EPFL scientists have discovered gene variants that make children life-threatening susceptible to common-cold viruses. Although most children can handle viral respiratory infections like the common cold, about 2% of children become sick enough to require hospitalization. There are some known risk factors for this, but severe illness still affects 1 in 1000 previously healthy kids.

A gene increases the severity of common colds
A gene increases the severity of common colds
Researchers funded by the SNSF have discovered mutations that worsen respiratory infections among children. Their study explain the mechanism involved. Colds that are not linked to influenza are generally benign. Still, 2% of each generation of children have to go to hospital following a virulent infection.

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.

New bacterial defense mechanism of the CRISPR-Cas system uncovered
New bacterial defense mechanism of the CRISPR-Cas system uncovered
The CRISPR-Cas system is an immune system that is found in many bacteria. It provides protection from viruses and other molecular parasites that can invade the bacterium and take over its genome. In these systems, the immunity is mediated by a complex multi-protein molecular machinery that uses RNA molecules as molecular guides to recognize the invader and target it for destruction.

Unbalanced wind farm planning exacerbates fluctuations
Unbalanced wind farm planning exacerbates fluctuations
If European countries cooperated better in the field of wind energy, wind power output would fluctuate less. This is the conclusion reached by a group of energy and climate researchers at ETH Zürich and Imperial College London, who for the first time have combined a long-term analysis of predominant weather patterns with Europe-wide wind electricity generation.

A new ligand extends the half-life of peptides from minutes to days
A new ligand extends the half-life of peptides from minutes to days
EPFL scientists have developed a ligand molecule that connects peptide drugs to blood-serum albumin and keeps them from being cleared out by the kidneys too soon. The ligand is easy to synthesize and can extend the half-life of therapeutic peptides from minutes to several days. Peptides are biological molecules, made up of short sequences of amino acids.

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.

How social rank can trigger vulnerability to stress
How social rank can trigger vulnerability to stress
EPFL scientists have identified rank in social hierarchies as a major determining factor for vulnerability to chronic stress. They also show that energy metabolism in the brain is a predictive biomarker for social status as well as stress vulnerability and resilience. Stress is a major risk factor for a range of psychopathologies.

RNA Molecules Live Short Lives
RNA Molecules Live Short Lives
A research group at the Biozentrum, University of Basel, has developed a new method to measure the half-life of RNA molecules. The study revealed that commonly used methods provide distorted results and that RNA molecules live an average of only two minutes, ten times shorter than previously assumed.

Obstacle course for caterpillars
Obstacle course for caterpillars
Spines and thorns keep hungry mammals at bay - or at least, that's the conventional wisdom. However, ETH researchers have now shown that spiky growths on plants make life difficult for caterpillars too. This finding could be important for crop breeding. "Caterpillars can occasionally be skewered by the spines," says Rupesh Kariyat, a scientist at ETH Zurich's Institute of Integrative Biology.

Generous people live happier lives
Generous people live happier lives
What some have been aware of for a long time, others find hard to believe: Those who are concerned about the well-being of their fellow human beings are happier than those who focus only on their own advancement. Doing something nice for another person gives many people a pleasant feeling that behavioral economists call a warm glow .

How Cats and Cows Protect Farm Children from Asthma
How Cats and Cows Protect Farm Children from Asthma
More and more people suffer from allergies and asthma. In the past decades, these diseases have massively increased in industrialized countries. Today, about 30 percent of children have allergies - with the exception of farm children. Among farm children, the disease is increasing less dramatically than in the case of their friends who live in the same village, but not on a farm.

Concrete from wood
Researchers from the National Research Programme "Resource Wood" have developed a type of concrete that largely consists of wood. The building material offers the construction industry new possibilities and is based in large part on renewable resources. Houses can be made of wood, as they were in the past - or of concrete, as they are today.

Naturalness as a success factor
Naturalness as a success factor
‘Naturalness' is a construct - but according to a new study from the ETH Consumer Behavior group, a product's success on the food market is primarily defined by whether or not consumers perceive it as natural. The increasingly artificial and virtual nature of everyday life has now achieved broad acceptance, and the benefits that technological development bring to everyone cannot be denied.
