A wound dressing that kills bacteria
A wound dressing that kills bacteria
In order to combat bacterial wound infections, Empa researchers have developed cellulose membranes equipped with antimicrobial peptides. Initial results show: The skin-friendly membranes made of plant-based materials kill bacteria very efficiently. If germs invade a wound, they can trigger a long-lasting infection that may fail to heal or even spread throughout the body, leading to life-threatening blood poisoning (sepsis).

Fireflies shed light on the function of mitochondria
The mitochondria provide energy for our cells, yet their role in many diseases is still poorly understood. Thanks to a bioluminescent molecule, scientists at EPFL can observe them at work in living mammals Tiny factories float inside our cells and provide them with almost all the energy they need: the mitochondria.

A titanate nanowire mask that can eliminate pathogens
A titanate nanowire mask that can eliminate pathogens
Filter "paper" made from titanium oxide nanowires is capable of trapping pathogens and destroying them with light. This discovery by an EPFL laboratory could be put to use in personal protective equipment, as well as in ventilation and air conditioning systems. As part of attempts to curtail the Covid-19 pandemic, paper masks are increasingly being made mandatory.

Mathematical program helps perform more efficient radiosurgery
Mathematical program helps perform more efficient radiosurgery
Engineers at EPFL and local startup Intuitive Therapeutics have developed software that can produce optimized surgical plans for Gamma Knife radiosurgery. Doctors at the Lausanne University Hospital (CHUV) began using the software in July. Radiosurgery is a kind of radiotherapy where doctors administer a high dose of radiation to diseased tissue with extreme precision, and in one go rather than over several sessions.

REM sleep tunes eating behaviour
REM sleep tunes eating behaviour
Despite our broad understanding of the different brain regions activated during rapid-eye-movement sleep, little is known about what this activity serves for. Researchers at the University of Bern and the Inselspital have now discovered that the activation of neurons in the hypothalamus during REM sleep regulates eating behaviour: suppressing this activity in mice decreases appetite.

Discovery shows promise for treating Huntington's Disease
Scientists at EPFL's Brain Mind Institute have identified an enzyme that can play a central role in developing a new route of treatment for Huntington's Disease. Huntington disease is a progressive and aggressively debilitating brain disorder that causes uncontrolled movements, psychological problems, and loss of cognition.

Acetate regulates immune cells for a precisely orchestrated immune defense
Acetate regulates immune cells for a precisely orchestrated immune defense
The concentration of acetate increases particularly sharply at the site of an infection in the body. As reported in the journal Cell Metabolism by a team of researchers from the University of Basel and colleagues, acetate supports the function of certain immune cells and thus helps to eliminate pathogens safely and efficiently.

Rapid test for the determination of antibodies against SARS-CoV-2
Rapid test for the determination of antibodies against SARS-CoV-2
A Swiss-German team presents a test that determines the amount of neutralising antibodies within a short period of time. The test was developed at the Institute of Virology and Immunology (IVI) of the University of Bern and the Swiss Federal Office for Food Safety and Animal Health, and evaluated in cooperation with colleagues from the Ruhr-University Bochum using serum samples from COVID-19 patients.

New approach for targeted cancer immunotherapy
New approach for targeted cancer immunotherapy
A new study from researchers at the University of Basel demonstrates that a novel cancer immunotherapy, based on a locally focused activation of immune cells, could help to more efficiently eradicate tumor cells and reduce side effects. Cancer immunotherapies make use of the ability of the immune system to attack cancer cells: they unleash the killer function of T cells, which then attack and eradicate the cancer cells.

Relatively High-Quality Reporting on Coronavirus Pandemic
Relatively High-Quality Reporting on Coronavirus Pandemic
In times of crisis, the media plays a particularly important role. Reporting was of a relatively high quality during the coronavirus pandemic, a study by the University of Zurich has shown. Some deficits, however, were found in the use of figures and statistics. In addition, many media outlets were not critical enough during the sensitive phase before the lockdown.

Iron deficiency during infancy reduces vaccine efficacy
About 40 percent of children around the globe suffer from anaemia because they do not consume enough iron. Now, studies by ETH researchers show that iron deficiency also reduces the protection provided by vaccinations. Despite the fact that global immunisation programmes are now reaching more people than ever, about 1.5 million children still die every year from diseases that vaccination could have prevented.

Primary care physicians during the COVID Epidemic-19
With a study covering 1,500 ambulatory patients, a team from the University of Geneva is highlighting the crucial role that general practitioners could play in the control of COVID-19. The global crisis triggered by COVID-19 has led governments to rely on the expertise of specialists in defining health emergency policies.

Restoring mobility by identifying the neurons that make it possible
Restoring mobility by identifying the neurons that make it possible
Partial mobility can be restored in rodents with impaired spinal cords. Using AI, scientists can now determine the ­cellular mechanisms responsible - a technique that may be applicable to many biomedical problems. Researchers at EPFL are able to get paralyzed rodents walking again by stimulating the animals' damaged spinal cords.

Blueprint for the perfect coronavirus app
Blueprint for the perfect coronavirus app
Many countries are turning to digital aids to help manage the COVID-19 pandemic. ETH researchers are now pointing out the ethical challenges, that need to be taken into account and the issues that need careful consideration when planning, developing and implementing such tools. Handwashing, social distancing and mask wearing: all these measures have proven effective in the current COVID-19 pandemic - just as they were 100 years ago when the Spanish flu was raging throughout the world.

Blueprint of Oxytocin Receptor Facilitates Development of New Autism Drugs
Blueprint of Oxytocin Receptor Facilitates Development of New Autism Drugs
Oxytocin plays a role in various mental health and sexual reproduction disorders. Researchers at the University of Zurich have now determined the three-dimensional structure of the oxytocin receptor to which the hormone binds. This knowledge could promote the development of novel drugs to treat a variety of diseases.

Brain 'signature' could help to diagnose schizophrenia
Brain ’signature' could help to diagnose schizophrenia
People with schizophrenia and their healthy siblings share patterns of brain activity that are different from those seen in individuals with no family history of the disorder, scientists from EPFL have found. Because the siblings do not show schizophrenia symptoms, this brain 'signature' could serve as a marker for the early diagnosis of the disorder.

Cystic fibrosis: why so many respiratory complications?
Cystic fibrosis: why so many respiratory complications?
By demonstrating the key role of Vav3 protein, UNIGE researchers highlight how the protein Vav3 creates bacterial docking stations to facilitate lung infections in cystic fibrosis. Cystic fibrosis, one of the most common genetic diseases in Switzerland, causes severe respiratory and digestive disorders.

Transplantable lab-grown organs move a step closer
A liver organoid developed at EPFL offers new promise in transplantation and the study of liver disease. Biologists and bioengineers at EPFL have designed a new method for growing simplified human mini-livers. Their process is a potentially important breakthrough in the quest for transplantable lab-grown tissues.

Basel study: Why lopinavir and lopinavir and hydroxychloroquine do not work on Covid-19
Basel study: Why lopinavir and lopinavir and hydroxychloroquine do not work on Covid-19
Lopinavir is a drug against HIV, hydroxychloroquine is used to treat malaria and rheumatism. Until recently, both drugs were regarded as potential agents in the fight against the coronavirus SARS-CoV-2. A research group from the University of Basel and the University Hospital has now discovered that the concentration of the two drugs in the lungs of Covid-19 patients is not sufficient to fight the virus.
