The human immune system is an early riser

Scientists show that activation of the immune system oscillates throughout the day, with a peak just before the start of the day

21-Oct-2021

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. By deciphering the cell migration mechanisms underlying the immune response, scientists from the University of Geneva ...

How to generate a brain of correct size and composition

13-May-2019

To build the neocortex, a brain area involved in higher cognitive functions, stem cells produce billions of neurons of various types. In a Science study, neuroscientists from Switzerland, Belgium, and the Institute of Science and Technology Austria (IST Austria) have now shown that, over time, ...

Eating less is healthy

New compounds may help in treating obesity

03-Sep-2018

Mice with a lower calorie intake live longer and are both healthier and leaner. A team of researchers funded by the SNSF may have found the reason for this positive effect: much of it is down to gut microbial communities and how they affect the immune system. The researchers also found compounds ...
