Cell senescence is regulated by innate DNA sensing
Cell senescence is regulated by innate DNA sensing
EPFL scientists have made new insights into the control of cell senescence, which is intimately linked to the development of cancer and ageing. Cells in the body or in cultures eventually stop replicating. This phenomenon is called "senescence" and is triggered by shortening of telomeres, oxidative stress or genetic damage to the cells, either acute or simply due to the cell growing "old".

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.

Body ownership is not impaired in schizophrenia
Body ownership is not impaired in schizophrenia
Answering a long-standing question, EPFL scientists have determined that the sense of body ownership is not affected in schizophrenia patients. Image: In the Full Body Illusion participants view their own backs being stroked, and when the seen and perceived stroking is synchronous a bodily illusion occurs causing them to feel illusory ownership over the viewed body.

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
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.
