Methods for reducing the risks of melting glaciers
Methods for reducing the risks of melting glaciers
Under a pilot project being spearheaded by the Swiss Agency for Development and Cooperation (SDC), a team of experts - including civil and environmental engineers from EPFL - are studying methods to help protect a region of the Andes Mountains threatened by glacial retreat. The testing phase of the pilot project will conclude at the end of the month.

Optic nerve stimulation to aid the blind
Optic nerve stimulation to aid the blind
EPFL scientists are investigating new ways to provide visual signals to the blind by directly stimulating the optic nerve. Their preliminary study on animals uses a new type of neural electrode and provides distinct signals. Scientists from EPFL in Switzerland and Scuola Superiore Sant'Anna in Italy are developing technology for the blind that bypasses the eyeball entirely and sends messages to the brain.

Cows Influence Plant Composition of Pastures
Cows Influence Plant Composition of Pastures
Angus, or Scottish Highland: not all cows are the same when it comes to a preference for different shrub, herbaceous and grass species. Research work carried out by Agroscope with the Universities of Heidelberg and Göttingen in Germany shows that cattle breed influences the botanical composition of pasture.

When liver disease affects the brain
When liver disease affects the brain
Scientists have demonstrated how chronic liver diseases cause molecular changes in the brain. They carried out their research using the 9.4 Tesla high-magnetic-field MRI machine at the Center for Biomedical Imaging (CIBM) at EPFL. The liver plays a vital role as a filter in the human body.

Smart interaction between proteins
Smart interaction between proteins
Very little was known till now about DNA repair by homologous recombination, which is fundamental for human health. Now an ETH research group has for the first time isolated and studied all the key proteins involved in this process, laying the foundation for investigating many diseases. Within our body, the process of cell division is constantly creating new cells to replace old or damaged ones.

Function from structure: the double life of a DUB
Deubiquitinases (DUBs) play a general role removing protein-degrading ubiquitins throughout the cell and are not typically known for specificity. Analyzing the two protein complexes BRISC and BRCA1-A, which have the same DUB core but play different roles in human biology, the Thomä group - in a collaboration with the Novartis Institutes for BioMedical Research (NIBR) - showed that DUBs can have diversified targeting and regulatory functions.

Humans May Have Had Key Role in Cave Bear Extinction
Humans May Have Had Key Role in Cave Bear Extinction
Humans may have played a substantial role in the extinction of the European cave bear at the end of the last ice age. These findings of a study with the involvement of the University of Zurich suggest a drastic cave bear population decline starting around 40,000 years ago. Where in Europe did different populations of cave bears live and how they did they migrate during the Late Pleistocene? This is the topic that Verena Schünemann from the Institute of Evolutionary Medicine at the University of Zurich and a team of researchers investigated.

Heatwaves Increase Emergency Admissions to Swiss Hospitals
Heatwaves Increase Emergency Admissions to Swiss Hospitals
Numerous studies have shown that heat increases mortality rates. 1,2 In Switzerland, for example, the hot summer of 2015 caused around 800 additional deaths. 3 Only a few studies, however, have investigated the effects of heatwaves on morbidity and hospital admissions. Researchers from the Swiss Tropical and Public Health Institute (Swiss TPH) recently conducted a detailed analysis of emergency hospital admissions in Switzerland during the three heatwaves between June and August 2015 in a study commissioned by the Federal Office for the Environment (FOEN).

Pesticides Transformation products pollute groundwater
Pesticides Transformation products pollute groundwater
13 substances were detected for the first time in groundwater, 15 were found in concentrations above 100 ng/L. This is the threshold value for pesticides under the Water Protection Ordinance. The researchers are particularly targeting metabolites of chlorothalonil, a product used against fungal attack in cereal, vegetable, wine and ornamental plant cultivation.

A miniature stretchable pump for the next generation of soft robots
A miniature stretchable pump for the next generation of soft robots
Scientists at EPFL have developed a tiny pump that could play a big role in the development of autonomous soft robots, lightweight exoskeletons and smart clothing. Flexible, silent and weighing only one gram, it is poised to replace the rigid, noisy and bulky pumps currently used. The scientists' work has just been published in Nature.

Revolutionising the CRISPR method
Revolutionising the CRISPR method
Researchers at ETH Zurich have refined the famous CRISPR-Cas method. Now, for the very first time, it is possible to modify dozens, if not hundreds, of genes in a cell simultaneously. Everyone's talking about CRISPR-Cas. This biotechnological method offers a relatively quick and easy way to manipulate single genes in cells, meaning they can be precisely deleted, replaced or modified.

Monitoring the Matterhorn with millions of data points
A unique project is linking in-situ measurements with natural hazards research. For the past ten years, a network of wireless sensors on the Matterhorn's Hörnli ridge has been constantly streaming measurement data on the condition of steep rock faces, permafrost and prevailing climate. The project leader, Jan Beutel, reviews progress to date.

How our biological clocks are locked in sync
Scientists from EPFL's Institute of Bioengineering have discovered that our circadian clock and our cell-cycle are in fact, synchronized. Nothing in biology is static; everything is fluid, dynamic and ever-moving. Often, this movement occurs in repeating patterns - regular, measurable cycles that tick just like "clocks".

An algorithm to detect outside influences on the media
An algorithm to detect outside influences on the media
EPFL researchers recently developed an algorithm that maps out the media landscape and reveals biases and hidden influences in the news industry. News consumers may not be aware that the way their local media outlet selects and presents news stories can be affected by the media group that owns it. At a time of rampant disinformation, it is just this sort of outside influence on the media that people should know about.

The world’s smallest stent
Researchers at ETH Zurich have developed a new method for producing malleable microstructures ' for instance, vascular stents that are 40 times smaller than previously possible. In the future, such stents could be used to help to widen life-threatening constrictions of the urinary tract in foetuses in the womb.

Tiny biodegradable circuits for releasing painkillers inside the body
EPFL researchers have developed biodegradable microresonators that can be heated locally with a wireless system. Doctors could soon be using them in implants to control the release of painkillers within tissue. Patients fitted with an orthopedic prosthetic commonly experience a period of intense pain after surgery.

Malaria Mortality in Africa May Be Higher than Estimated
Malaria Mortality in Africa May Be Higher than Estimated
Previous studies analysing malaria mortality in sub-Saharan Africa may have underestimated the burden caused by this mosquito-borne disease. A study by Swiss TPH researchers found that when taking into account indirect causes of death such as anaemia, the risk of death from malaria was up to 3.5 times higher.

Future clinical studies in lymphoma patients
At the Institute of Oncology Research (IOR, affiliated to USI), researchers have discovered two molecules, so far known in the field of treatments against Ewing's sarcoma, which have strong antilymphoma activity, thus proposing clinical studies on patients. The study has been published in the scientific journal Clinical Cancer Research .

Unlocking the secrets of an important regulator of human development
Unlocking the secrets of an important regulator of human development
The protein TRIM71 is an important regulator of animal development and plays a role in various diseases. In close collaboration, scientists from the groups of Helge Grosshans and Marc Bühler at the FMI elucidated the mechanism by which TRIM71 binds and turns off its RNA targets. They also identified several core targets of TRIM71, including proteins involved in genetic disorders.
