Neutral mutants can prevail in gut microbiota, enhancing diversity
Scientists at EPFL and Sorbonne propose a new model of the diversity and evolution of gut bacteria that shows how the gut environment helps neutral mutations become prevalent, with significant potential implications on health and metabolic diseases. -We are used to thinking of evolution as a very slow process, and this is definitely the case for large mammals etc,- says Professor Anne-Florence Bitbol at EPFL's School of Life Sciences.

The unexpected benefits of fat in type 2 diabetes
The unexpected benefits of fat in type 2 diabetes
Scientists from the University of Geneva have discovered that fat may help the pancreas adapt to excess sugar, thereby slowing down the onset of diabetes. With nearly 10% of the world's population affected, type 2 diabetes is a major public health issue. An excessively sedentary lifestyle and a too-caloric diet encourage the development of this metabolic disease by altering the functioning of pancreatic cells and making blood sugar regulation less effective.

School Closures Led to More Sleep and Better Quality of Life for Adolescents
School Closures Led to More Sleep and Better Quality of Life for Adolescents
The school closures in spring 2020 had a negative effect on the health and well-being of many young people. But homeschooling also had a positive flipside: Thanks to sleeping longer in the morning, many teenagers reported improved health and health-related quality of life. The study authors from the University of Zurich therefore believe school days should begin later in the morning.

T cells: No time to die
T cells: No time to die
They are at the forefront in the fight against viruses, bacteria, and malignant cells: the T cells of our immune system. But the older we get, the fewer of them our body produces. Thus, how long we remain healthy also depends on how long the T cells survive. Researchers at the University of Basel have now uncovered a previously unknown signaling pathway essential for T cell viability.

Mechanism for DNA invasion of Adenoviral Covid-19 Vaccines Discovered
Mechanism for DNA invasion of Adenoviral Covid-19 Vaccines Discovered
Adenoviruses have a linchpin protein that stabilizes their DNA until it reaches the infected cell's nucleus. The protein then detaches from the viral genome, and the virus uncoats. Only then are the genes released into the nucleus, which is necessary for the production of new viruses. This process, discovered by researchers at the University of Zurich, is a key for effective functioning of various Covid-19 vaccines.

New muscle layer discovered on the jaw
New muscle layer discovered on the jaw
Human anatomy still has a few surprises in store for us: researchers at the University of Basel have discovered a previously overlooked section of our jaw muscles and described this layer in detail for the first time. The masseter muscle is the most prominent of the jaw muscles. If you place your fingers on the back of your cheeks and press your teeth together, you'll feel the muscle tighten.

Assessing the Potential Health Impact of Omicron
Assessing the Potential Health Impact of Omicron
Cases of SARS-CoV-2 variant Omicron are surging in numerous settings, with early evidence suggesting Omicron is more infectious than the Delta variant. It is not yet known, however, if Omicron has higher severity or if vaccines are less effective. New research from Swiss TPH now provides guidance to decision-makers on Omicron's potential public health impact for a range of different scenarios.

An enemy within: Pathogens hide in tissue
An enemy within: Pathogens hide in tissue
Antibiotics cure many bacterial infections. However, some patients suffer a relapse. A research group at the University of Basel has now discovered why some bacteria can survive antibiotic therapy. The team uncovered where the bacteria hide in the body and how the body's own immune system also plays an important role.

More infections in poorly ventilated classrooms
More infections in poorly ventilated classrooms
Indoor air quality has an influence on how many corona virus infections occur there. This has now been shown for the first time in a pilot project involving researchers in 150 primary school classrooms in Graubünden. The analysis also showed that the air quality in many classrooms is poor. The study concluded that regular ventilation of classrooms is therefore very important, even in winter months.
