In a study published in Neuron, researchers have demonstrated how functional ultrasound imaging can yield high-resolution, unbiased, brain-wide activity maps of behaving mice.
The water in Swiss streams is contaminated with numerous micropollutants. However, very little research has been carried out to determine how these trace substances affect organisms in bodies of water.
Farmers in developing countries often rely heavily on their yearly harvest to feed their families. A bad crop can have severe consequences for their livelihood.
A new study found two types of climatic connection between the North Atlantic and Antarctica. One is a rapid atmospheric channel and the other a much slower connection through the ocean.

Taking cholesterol-lowering drugs, or statins, as a preventive measure can reduce the risk of cardiovascular disease. A study by the University of Zurich now shows that this measure is recommended too often, as current guidelines fail to take into account the risks of side effects. Even healthy people who don't suffer from a cardiovascular disease are prescribed cholesterol-lowering drugs, known as statins, if they meet certain risk criteria.
In a study published in Neuron, researchers have demonstrated how functional ultrasound imaging can yield high-resolution, unbiased, brain-wide activity maps of behaving mice. These can lead to a brain-wide understanding of how brain activity relates to specific behavior - in healthy mice and in mouse models of neurologic or psychiatric diseases.
Farmers in developing countries often rely heavily on their yearly harvest to feed their families. A bad crop can have severe consequences for their livelihood. Despite the significant advantages crop insurances would offer in alleviating this risk, only a small percentage of farmers insure their crops.
The water in Swiss streams is contaminated with numerous micropollutants. However, very little research has been carried out to determine how these trace substances affect organisms in bodies of water. An Eawag research group has been able to show for the first time on a large scale that such trace substances accumulate in gammarids and possibly have a negative effect on them.
A new study found two types of climatic connection between the North Atlantic and Antarctica. One is a rapid atmospheric channel and the other a much slower connection through the ocean. During the last glacial period, these links resulted in abrupt climatic changes - and could so again in future. In a study just published in the journal "Nature", an international team of researchers describes how an ocean current repeatedly strengthening and weakening again 60,000 to 12,000 years ago led to an extremely sudden change in the climate.
By comparing the cities of Geneva and Singapore, a thesis found that urban planners can reap multiple benefits by better leveraging digital technology.
Stem-cell transplantation is an effective form of therapy to fight leukemia. In many cases, however, the transferred immune cells of the donor also attack the recipients' healthy tissue ' often with fatal consequences. Researchers at the University of Zurich have now identified a molecule that plays a key role in this process.
Like "going from hand-drawn maps to Google Earth," the Blue Brain Cell Atlas allows anyone to visualize every region in the mouse brain, cell-by-cell - and freely download data for new analyses and modelling. The first digital 3D atlas of every cell in the mouse brain provides neuroscientists with previously unavailable information on major cell types, numbers and positions in all 737 brain regions - which will potentially accelerate progress in brain science massively.
A study conducted by Agroscope's Swiss National Stud Farm (SNSF) in collaboration with the University of Neuchâtel refuted the assumption that cribbing horses perform less well in complicated learning situations than other horses. All horses in the study were able to recognise symbols as well as solve inverse conclusion exercises, which are difficult for horses.
"We are polluting the rivers and the natural elements, and even ruining the very thing that is essential to life - the air." These words were not spoken by nature conservationists in the 21st century but flowed from the pen of the Roman scholar Pliny the Elder. In fact ancient history researchers agree today that even in Roman times the environment was being polluted - by unfiltered wastewater, the mining of metals such as iron or lead and clear-cutting of the forests.
Most European forests are primarily used for timber production. However, woodlands also offer spaces for recreation and they store carbon but it is not clear how forests can be managed for these multiple benefits. A new study under the direction of the University of Bern is now showing how forestry can be improved so that wooded areas can fulfill as many services as possible.
EPFL researchers have developed a hydrogel - made up of nearly 90% water - that naturally adheres to soft tissue like cartilage and the meniscus. If the hydrogel carries repair cells, it could help damaged tissue to heal. Some types of body tissue, like cartilage and meniscus, have little or no blood supply and are unable to heal if damaged.
Researchers have determined the three-dimensional structure of a receptor that controls the release of calcium from bones. The receptor is now one of the main candidates for developing new drugs to treat osteoporosis. Knowing the receptor's blueprint will be instrumental for designing drugs that could even help to rebuild bones.
The scene may be familiar from natural history documentaries - a migrating herd of wildebeest attempt to cross a raging river, with many of the creatures drowning in the process - but what viewers do not generally notice is that large amounts of carbon are thereby transported from a grassland to an aquatic ecosystem.
Thanks to sensors attached to their shoes, long-distance runners can harness the power of algorithms to analyze their stride. The algorithms, developed by EPFL spin-off Gait Up and tested in the Laboratory of Movement Analysis and Measurement (LMAM), are unmatched in terms of precision and the range of parameters measured, such as objective fatigue, cadence, strike angle and foot impact.
An antibiotic called thanatin attacks the way the outer membrane of Gram-negative bacteria is built. Researchers at the University of Zurich have now found out that this happens through a previously unknown mechanism. Thanatin, produced naturally by the spined soldier bug, can therefore be used to develop new classes of antibiotics.
EPFL scientists have discovered how a dysfunction in the immune system can cause an overload of a gut bacterium. The bacterium produces excess lactic acid, which in turn triggers the production of reactive oxygen species that cause damage to cells and many age-related pathologies. There is no doubt that gut bacteria have become one of the most important focuses of biological and medical research today.
Researchers have developed an emotional intelligence test for the workplace that can be used to assess and predict an employee's abilities in interpersonal relations and leadership capabilities.
Switzerland is becoming drier, hotter and less snowy, and will struggle with heavier rainfall in the future - these are the conclusions reached by climate researchers from MeteoSwiss and ETH Zurich.
