Researchers from EPFL and HES-SO Valais have modeled the Swiss energy system under the hypothetical constraints of carbon neutrality and energy independence by 2050. The results show that these two constraints could be met while reducing energy system costs by about 30% compared to 2020.

Health professionals are in urgent need of new antibiotics to tackle resistant bacteria. Researchers at the University of Zurich and the company Spexis have now modified the chemical structure of naturally occurring peptides to develop antimicrobial molecules that bind to novel targets in the bacteria's metabolism.

Researchers have found that droughts and land water variability have had increasing effect on the carbon cycle in the tropics over the last sixty years. Most climate models fail to capture this observation. This could mean that terrestrial ecosystems could absorb less CO2 than expected in their role as carbon sinks in the future.

In the case of blood poisoning, the bacteria in the blood must be identified as fast as possible so that a life-saving therapy can be started. researchers have now developed "sepsis sensors" with magnetic nanoparticles that detect bacterial pathogens within a short period of time and identify suitable candidates for antibiotic therapies.

Not so long ago, seeing a griffon vulture in Switzerland was an extraordinary sight. For the past ten years, the species has been regularly crossing our skies. Many vulture species are threatened worldwide. The return of the griffon vulture to Europe goes against this trend and is a great success for nature conservation

Researchers from EPFL and HES-SO Valais have modeled the Swiss energy system under the hypothetical constraints of carbon neutrality and energy independence by 2050. The results show that these two constraints could be met while reducing energy system costs by about 30% compared to 2020. A carbon-neutral and independent Swiss energy system in 2050 is theoretically achievable using the currently untapped local renewable energy resources.

How the flu virus hacks our cells
How the flu virus hacks our cells
A team from the University of Geneva has discovered how the influenza A virus hijacks the mechanism for importing iron into cells to invade its host. Influenza epidemics, caused by influenza A or B viruses, result in acute respiratory infection. They kill half a million people worldwide every year. These viruses can also wreak havoc on animals, as in the case of avian flu.

Actively reducing noise by ionizing air
Actively reducing noise by ionizing air
Scientists show that a thin layer of plasma, created by ionizing air, could be promising as an active sound absorber, with applications in noise control and room acoustics. Did you know that wires can be used to ionize air to make a loudspeaker? Simply put, it's possible to generate sound by creating an electric field in a set of parallel wires, aka a plasma transducer, strong enough to ionize the air particles.

An algorithm for sharper protein films
Proteins are biological molecules that perform almost all biochemical tasks in all forms of life. In doing so, the tiny structures perform ultra-fast movements. In order to investigate these dynamic processes more precisely than before, researchers have developed a new algorithm that can be used to evaluate measurements at X-ray free-electron lasers such as the SwissFEL more efficiently.

Breaking the ice over a 40-year problem of supercooled water
Breaking the ice over a 40-year problem of supercooled water
Researchers at EPFL have found a way to study water in "no man's land," a subzero temperature range where water crystallizes rapidly. Historically, the inability to access "no man's land" has prevented researchers from unriddling the anomalous nature of water, but the breakthrough method can now change that.

Mindful meditation helps us make better decisions
People who meditate every day are less likely to avoid negative information. This is a finding in a new study by a research team including researchers from ETH Zurich. Smart decision makers gather all the pertinent information, and weigh the pros and cons dispassionately. This also includes gathering information that could prove unsettling or unpleasant.

4 new genetic variants associated with weight gain
A research group at the University of Lausanne has carried out the largest genome-wide study of weight gain induced by psychotropic drugs. This work has identified 4 new genetic variants associated with this metabolic disorder. Interindividual variability in psychotropic drug-induced weight gain The prevalence of metabolic disorders in the psychiatric population is a cause for concern, and particularly high among patients taking psychotropic drugs that induce weight gain.

Scepticism about Microsoft results
Scepticism about Microsoft results
In March 2022, Microsoft published research results about the realisation of a special type of particle that might be used to make particularly robust quantum bits. Researchers at the University of Basel are now calling these results about so-called Majorana particles into doubt: through calculations they have shown that the findings can also be explained differently.

Safe Aid: Protecting privacy in humanitarian operations
Researchers have worked with the International Committee of the Red Cross (ICRC) to develop a first of its kind, digital system to support humanitarian aid distribution. The design uses tokens to decentralize the storage and processing of recipients information, reducing the risk of harm, and uses advanced cryptography to enable accountability.

’For very small problem sizes a classical computer is faster’
In theory, quantum computers vastly outperform classical computers in terms of computing speed. For them to do so in practice, it is necessary to design more and novel high-speed algorithms, says ETH supercomputing specialist Torsten Hoefler. Quantum computers promise to be capable of solving some computational problems much faster than classical computers.

How cells feed on RNA
Scientists have discovered that cells can use RNA and its constituent uridine as alternative energy sources to sugar. For better or for worse, as shown by their publication in "Nature Metabolism ". Each cell contains the genetic material necessary for the activity of the organism. RNA, or ribonucleic acid, is an important molecule for making proteins from the instructions contained in the genes.

Supposedly rare diseases aren't as rare as previously thought
Supposedly rare diseases aren’t as rare as previously thought
Rare diseases are often caused by defects in genetic material. If children inherit only a defective gene from one parent, they often are asymptomatic -carriers or at least that was the previous assumption. However, a research team from the University of Basel and the University Hospital Basel is now reporting that such carriers can also suffer from life-threatening diseases - and that rare hereditary diseases are therefore probably more common than previously thought.

Researchers successfully apply quantum computing in practice
Researchers successfully apply quantum computing in practice
Compared to classical computers, quantum computers can solve complex problems in parallel and thus faster, but they are also more prone to errors. ZHAW researchers show how a hybrid approach can be used to exploit the strengths of quantum computers in a targeted manner. Quantum computers not only know the state 0 and 1, but can also represent several states between 0 and 1 by means of so-called qubits - analogous to bits of classical computers - and thus calculate many possible results simultaneously.
