Ultrafast optical switching can save overwhelmed datacenters
Ultrafast optical switching can save overwhelmed datacenters
EPFL and Microsoft Research scientists demonstrated ultrafast optical circuit switching using a chip-based soliton comb laser and a completely passive diffraction grating device. This particular architecture could enable an energy-efficient optical datacenter to meet enormous data bandwidth requirements in future.

Towards Precision Medicine for Dialysis Patients
Towards Precision Medicine for Dialysis Patients
A common gene variant for the protein Aquaporin-1 lowers the amount of water channels in the cell membranes. This reduces water transport and leads to a higher risk of death in patients with kidney failure treated with peritoneal dialysis. In such cases, specific osmotic solutions should be used, as an international research team led by the University of Zurich has shown.

The human immune system is an early riser
The human immune system is an early riser
Swiss and German scientists show that activation of the immune system oscillates throughout the day, with a peak just before the start of the day. Circadian clocks, which regulate most of the physiological processes of living beings over a rhythm of about 24 hours, are one of the most fundamental biological mechanisms.

New active agent against parasites
New active agent against parasites
Researchers at the Paul Scherrer Institute PSI have identified a chemical compound that may be suitable as an active agent against several different unicellular parasites. Among these are the pathogens that cause malaria and toxoplasmosis. The point of attack for this promising substance is the protein tubulin: It helps cells divide and therefore is essential for the multiplication of the parasites.

Ultrafast control of quantum materials
Ultrafast control of quantum materials
An international team with participation of the Paul Scherrer Institute PSI shows how light can fundamentally change the properties of solids and how these effects can be used for future applications. The researchers summarise their progress in this field, which is based among other things on experiments that can also be carried out at the Swiss X-ray free-electron laser SwissFEL, in the scientific journal Reviews of Modern Physics .

Plankton head polewards
Ocean warming caused by anthropogenic greenhouse-gas emissions will prompt many species of marine plankton to seek out new habitats, in some cases as a matter of sur-vival. researchers expect many organisms to head to the poles and form new communities - with unforeseeable consequences for marine food webs.

Social media and AI can measure the aesthetic quality of landscapes
Social media and AI can measure the aesthetic quality of landscapes
To measure an ecosystem's beauty and the well-being it produces for people can help inform public environmental policy. Scientists at EPFL and Wageningen University in the Netherlands have developed a novel modeling approach for ecosystem assessments based on deep learning and millions of Flickr photos.

Swissuniversities warns of a medicine and research ban
The adoption of the initiative for a ban on animal and human experimentation would prevent biomedical research and new medical treatments in particular. The high quality of healthcare and responsible research in Switzerland to the benefit of the population and the environment are at stake.

Sustainable farming: There's no one solution
Sustainable farming: There’s no one solution
Sustainable agriculture will not be achieved by one universal solution. A meta-analysis by the University of Basel shows that the current focus on no-till farming does not achieve the desired results. A sustainable system of agriculture must be designed for local needs and in dialog with local farmers.

New proteins enable scientists to control cell activities
New proteins enable scientists to control cell activities
Scientists have developed new controlled proteins and used to switch cellular activities on and off like a light bulb. Sailan Shui, a doctoral assistant at EPFL's Laboratory of Protein Design and Immunoengineering, enjoys playing with proteins, activating and deactivating them as she wishes, as if light switches that can be turned on and off.

Exotic magnetic states in miniature dimensions
Exotic magnetic states in miniature dimensions
Led by scientists at Empa and the International Iberian Nanotechnology Laboratory, an international team of researchers from Switzerland, Portugal, Germany, and Spain have succeeded in building carbon-based quantum spin chains, where they captured the emergence of one of the cornerstone models of quantum magnetism first proposed by the 2016 Nobel laureate F. D.

The planet does not fall far from the star
The planet does not fall far from the star
A compositional link between planets and their respective host star has long been assumed in astronomy. For the first time now, a team of scientists, with the participation of researchers of the National Centre of Competence in Research (NCCR) PlanetS from the University of Bern and the University of Zürich, deliver empirical evidence to support the assumption - and partly contradict it at the same time.

Did Venus, Earth's twin sister, ever have oceans?
Did Venus, Earth’s twin sister, ever have oceans?
Astrophysicists led by the UNIGE and the NCCR PlanetS have investigated the past of Venus to find out whether Earth's sister planet once had oceans. The planet Venus can be seen as the Earth's evil twin. At first sight, it is of comparable mass and size as our home planet, similarly consists mostly of rocky material, holds some water and has an atmosphere.

How to force photons to never bounce back
How to force photons to never bounce back
Scientists have developed a topology-based method that forces microwave photons to travel along a one way path, despite unprecedented levels of disorder and obstacles on their way. This discovery paves the way to a new generation of high-frequency circuits and extremely robust, compact communication devices.

Highly potent antibody against SARS-CoV-2
Highly potent antibody against SARS-CoV-2
Scientists at Lausanne University Hospital (CHUV) and EPFL have discovered a highly potent monoclonal antibody that targets the SARS-CoV-2 spike protein and is effective at neutralizing all variants of concern identified to date, including the delta variant. Their findings are published in the prestigious journal Cell Reports.

The underground as a haven for biodiversity
The underground as a haven for biodiversity
Europe has relatively low biodiversity compared to most other continents because many species became extinct during the ice ages. In subterranean ecosystems, however, which were shielded from climatic turbulences, a great diversity of ancient species were able to survive. This is the conclusion of a study on the amphipod genus Niphargus.

A cryptography game-changer for biomedical research at scale
Personalized medicine is set to revolutionize healthcare, yet large-scale research studies towards better diagnoses and targeted therapies are currently hampered by data privacy and security concerns. New global collaborative research has developed a solution to these challenges, described. Predictive, preventive, personalized and participatory medicine, known as P4, is the healthcare of the future.

An efficient and low-cost approach to detecting food fraud
An efficient and low-cost approach to detecting food fraud
Fraudulent practices in food production, especially false claims of geographical origin, cause billions of dollars in economic damage every year. Botanists at the University of Basel have now developed a model that can be used to determine the origin of food in an efficient and low-cost manner. Strawberries from Switzerland or olive oil from Italy can be sold at much higher prices than the same products from other countries.

How to better identify dangerous volcanoes
How to better identify dangerous volcanoes
The more water is dissolved in the magma, the greater the risk that a volcano will explode. A new ETH study now shows that this simple rule is only partially true. Paradoxically, high water content significantly reduces the risk of explosion. Volcanologists have long been troubled by two questions: When exactly will a volcano erupt next?
