Scientists at Empa teamed up with isofloc AG to develop an insulating material made of recycled paper. It is ideal for prefabricated wooden elements and even multistory timber houses, and protects the construction against fire. What's more: The additive it contains is harmless to humans, animals and the environment.
Discovery of bacterial signature of intestinal disease
Researchers from the Department of Biomedical Research of the University of Bern and the University Clinic of Visceral Surgery and Medicine of the Inselspital Bern, Switzerland, have discovered that changes in the composition of the intestinal bacteria in patients with chronic inflammatory bowel disease affect the severity of the disease and the success of therapy.

Scientists at EPFL and ETH Zurich have developed tiny elastic robots that can change shape depending on their surroundings. Modeled after bacteria and fully biocompatible, these robots optimize their movements so as to get to hard-to-reach areas of the human body. They stand to revolutionize targeted drug delivery.
Molecules are usually formed in reaction vessels or laboratory flasks. An Empa research team has now succeeded in producing molecules between two microscopically small, movable gold tips - in a sense as a "hand-knitted" unique specimen. The properties of the molecules can be monitored in real time while they are being produced.
Using the fossil and fossilized footprints of a 300-million-year-old animal, an interdisciplinary team that includes scientists from EPFL and Humboldt-Universität zu Berlin have developed a method for identifying the most likely gaits of extinct animals and designed a robot that can recreate their walk.
Nudging, the concept of influencing people's behavior without imposing rules, bans or coercion, is an idea that government officials and marketing specialists alike are keen to harness, and itis often viewed as a one-size-fits-all solution. Now, a study by researchers from the University of Zurich puts things into perspective: Whether a nudge really does improve decisions depends on a person's underlying decision-making process.
Geneva. Today, the Future Circular Collider (FCC) collaboration submitted its Conceptual Design Report (CDR) for publication, a four-volume document that presents the different options for a large circular collider of the future. It showcases the great physics opportunities offered by machines of unprecedented energy and intensity and describes the technical challenges, cost and schedule for realisation.
Organ transplant rejection is a major problem in transplantation medicine. Suppressing the immune system to prevent organ rejection, however, opens the door to life-threatening infections. Researchers at the University of Basel's Biozentrum have now discovered a molecular approach preventing rejection of the transplanted graft while simultaneously maintaining the ability to fight against infections.
First-time precise measurement of gamma-ray bursts conducted successfully from a space station A detector called POLAR, developed at PSI, has been sent to outer space to collect data. In September 2016, the device was launched into Earth orbit on board the newest Chinese space station. From that vantage point, POLAR recorded so-called gamma-ray bursts flashing in the far reaches of the universe.
Potential for risky behavior is also in your genes
As part of an international research project, a group of scientists from the University of Zurich found genetic variants associated with risk tolerance and risky behaviors. It is one of the first studies to link genetic variants with behavioral outcomes, which are relevant to social science research.

An innovative combination therapy can force malignant breast cancer cells to turn into fat cells. This can be used to prevent the formation of metastases in mice, as researchers at the University of Basel's Department of Biomedicine recently reported in the journal Cancer Cell. Tumor cells can adapt dynamically to changing conditions thanks to their ability to reactivate a cellular process that is central to embryonic development.
A metabolic checkpoint for embryonic stem cell differentiation
Upon exit from self-renewal, embryonic cell stems differentiate into different types of tissues - a process regulated by various complex mechanisms. Recent work published by the Betschinger group shows the importance of the lysosome - which is directly associated with cellular metabolism and nutrition - in developmental progression.

The most deadly aspect of breast cancer is metastasis. It spreads cancer cells throughout the body. Researchers at the University and the University Hospital of Basel have now discovered a substance that suppresses the formation of metastases. The development of metastasis is responsible for more than 90% of cancer-related deaths, and patients with a metastatic disease are considered incurable.
Researchers of the University of Bern have discovered a new molecular regulatory mechanism in unicellular parasites which has never before been observed. RNA fragments do not act as brakes in the cell apparatus, but on the contrary as "stimulants": they boost protein production after periods of stress.
Speeding up genetic diagnosis of Huntington’s disease
Elongated segments of DNA cause Huntington's disease and certain other disorders of the brain. Researchers have developed a method to determine the length of the mutated genes quickly and easily. People with Huntington's disease suffer from jerky body movements and decreasing mental abilities. The condition usually leads to death 15-20 years after diagnosis.

How Drugs Can Minimize the Side Effects of Chemotherapy
Researchers at the University of Zurich have determined the three-dimensional structure of the receptor that causes nausea and vomiting as a result of cancer chemotherapy. The study explains for the first time why some drugs work particularly well in ameliorating these side effects. The results also provide important insights into how to develop compounds to effectively tackle other disorders.

This year, beautifully wrapped laptops, mobile phones or even new TV sets lay under numerous Christmas trees. They are enthusiastically put into use - and the old electronic devices are disposed of. The e-waste contains resources such as neodymium, indium and gold. What happens to the valuable materials' And how much rare metal is contained in mobile phones, computers and monitors that are still in use today? Empa researchers have investigated these questions.
Installing photovoltaic panels in high mountains could significantly reduce the power deficit experienced by this renewable energy in winter, according to a joint study by the WSL Institute for Snow and Avalanche Research SLF and EPFL. The Swiss Energy Strategy 2050 reflects the decision to abandon nuclear power in the medium term.
After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices. They were the first to control exciton flows at room temperature. And now, the team of scientists from EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) has taken their technology one step further.
Tumors backfire on chemotherapy
Chemotherapy is an effective treatment for breast cancer, yet some patients develop metastasis in spite of it. Researchers at EPFL have discovered that chemotherapy-treated mammary tumors produce small vesicles that may help them spread to other organs. The study is published. Some patients with breast cancer receive chemotherapy before the tumor is removed with surgery.
