In the future, astronauts on long missions in space will have to take care of their own farming. But will that even work? An unusual experiment by Eawag researcher was designed to find some of the answers. Life on our planet has always been under the influence of gravity. But how would soils, plants and other organisms react in a zero-gravity situation? Scientists have been puzzling over this question since last decades until now, and Eawag hydrologist and soil physicist, Joaquin Jimenez-Martinez and his colleagues are also keen to understand how zero gravity affects soil processes.
Researchers stimulated the nerves of the amputated arm with signals very similar to the natural ones, succeeding in "imitating the colors" of the evoked sensations of the various types of receptors and related nerve fibers present in the fingertips of the hand. This has brought greater realism and greater functionality of the feelings experienced by patients.
Scientists from EPFL and the University of Geneva have discovered a "code" of architect genes that are expressed in specific combinations during the development of hands and fingers. The study decrypts developmental gene expression at the level of the single cell in developing limbs and expands our understanding of the genetics behind growing limbs.
EPFL researchers have developed floating, solar-powered robots to help protect Chile's water reservoirs. These low-cost robots can be assembled together in a variety of ways on the water surface to prevent the water from evaporating - thereby preserving a precious resource in this arid country and one that's crucial to its biggest industry: winemaking.
Patients with a rare disease, called narcolepsy, suffer of excessive daytime sleepiness and cataplexy. A study published in the renowned scientific journal Nature reports the cause of the disease, which has previously been a mystery. The study is the result of a close collaboration between researchers from the University Sleep-Wake-Epilepsy-Centre Bern at the University Hospital (Inselspital), the Institute for Research in Biomedicine in Bellinzona and ETH Zurich.
Geneva, 18 September 2018. The largest liquid-argon neutrino detector in the world has just recorded its first particle tracks, signaling the start of a new chapter in the story of the international Deep Underground Neutrino Experiment (DUNE). DUNE's scientific mission is dedicated to unlocking the mysteries of neutrinos, the most abundant (and most mysterious) matter particles in the universe.
World’s largest Alzheimer’s survey reveals most adults believe a cure will be developed in their lifetime
From a sample of over 10,000 adults, 62% are worried that they may develop Alzheimer's disease and 91% believe the solution to tackling diseases lies in medical research 79% are willing to take part in medical research but three-quarters (75%) have no idea how to get involved This World Alzheimer's Month, in association with Alzheimer's Disease International, Novartis, Amgen and Banner Alzheimer's Institute are raising awareness about how to

EPFL chemists have developed a method that can significantly increase the yield of sugars from plants, improving the production of renewable fuels, chemicals, and materials. Producing fuels and chemicals from biomass (wood, grasses, etc.) is one of the most promising solutions for building a renewable economy.
Sleeping sickness-causing parasites contain an unusual protein synthesis machinery. A team of researchers from ETH Zurich and the University of Bern resolved its very special structure for the first time. Ribosomes are among the most important molecular machines within the cell that hardly changed in the course of evolution.
Facilitating diagnosis with a new type of biosensor
Scientists from the Max Planck Institute and EPFL have developed a new type of biosensor able to precisely quantify metabolites using a single drop of blood. The accuracy and simplicity of the procedure could make it a tool of choice for diagnosing and monitoring several diseases. Diseases or injuries can result in dramatic changes in the blood levels of metabolites, which are chemical compounds produced by the body's metabolism.

In Lakes Thun and Brienz, evolutionary biologists from Eawag and Bern University have discovered a new whitefish species. The species, provisionally named "Balchen2", is clearly differentiated - morphologically, ecologically and genetically - from the five Lake Thun whitefish species previously described.
A new technique makes it possible to obtain an individual fingerprint of the current-carrying edge states occurring in novel materials such as topological insulators or 2D materials. Physicists of the University of Basel present the new method together with American scientists in 'Nature Communications.' While insulators do not conduct electrical currents, some special materials exhibit peculiar electrical properties: though not conducting through their bulk, their surfaces and edges may support electrical currents due to quantum mechanical effects, and do so even without causing losses.
Reproductive hormones control a woman's monthly cycle and regulate fertility. Reproductive hormones are also related to how attractive a woman smells a study now shows. Researchers at the University of Bern demonstrate that some women smell better to men than others. Namely those who are "fittest" for reproduction.
Wastewater smells foul and is full of pathogens. For these reasons it is usually removed and disposed of quickly.
Around one percent of people infected with HIV produce antibodies that block most strains of the virus. These broadly acting antibodies provide the key to developing an effective vaccine against HIV. Researchers from the University of Zurich and the University Hospital Zurich have now shown that the genome of the HI virus is a decisive factor in determining which antibodies are formed.
EPFL scientists have mapped out the steps required to build a self-sustaining research base on Mars that would be habitable for the long term. Their work can help researchers set priorities for space programs exploring Mars as well as the solar system as a whole. If there was ever life on Mars, its traces are most likely to be found at the planet's poles.
Using biosensors to deliver personalized doses of antibiotics
A team of eight EPFL students has come up with a portable biosensor that can measure the amount of vancomycin in a patient's blood stream, enabling doctors to better control the dosage and reduce harmful side effects.

Climate warming is not the only cause of temperature changes in lakes, rivers and other bodies of water. The use of waterbodies for heating and cooling also leads to increases or decreases in water temperature. There has been little research to date, however, on how this affects aquatic ecosystems. This lack of understanding has been highlighted by a recent literature review carried out at Eawag and the University of Bern.
A team of researchers has shown that in multiple sclerosis, it is not only specific T cells that cause inflammation and lesions in the brain. B cells, a different type of immune cell, also play a role. These cells activate T cells in the blood. This discovery explains how new MS drugs take effect, opening up novel options for treating the disease.
Work published by Isabella Marcomini and the Gasser laboratory sheds light on how repeat sequences found in the DNA of eukaryotic genomes can prevent accurate repair of DNA breaks, leading to dangerous chromosomal rearrangements. Repeat sequences make up nearly 70% of the human genome. While their function is unclear, it is well established that repeats are a source of genomic instability.
