Physical exercise has many beneficial effects on human health, including the protection from stress-induced depression. However, until now the mechanisms that mediate this protective effect have been unknown.

An internal contest has been ongoing between a little band of researchers at Karolinska Institutet. And the one who succeeds in quoting Bob Dylan in most scientific articles before going into retirement is the winner.

[Edit: Bengt Samuelsson passed away on July 5, 2024. This article was written in 2014.] Karolinska Institutet’s former Vice-Chancellor, the Nobel Prize Laureate Bengt Samuelsson, reached the age of 80 in 2014. At the end of August that year, researchers from around the world, met up to honour him as founder of the research field Lipid Mediators with a three-day symposium.

Karolinska Institutet’s online courses will be available for everybody on the shared platform edX.org which is a non-profit platform that was founded by the two leading universities Harvard and the Massachusetts Institute of Technology (MIT).

The sensitivity of fat cells to signals that increase the breakdown of fat is linked to the receptor ALK7, according to a study by researchers at Karolinska Institutet. The discovery, which is published in the new scientific journal eLife, suggests that ALK7 might be an interesting target for future strategies to treat obesity.

A new study from Karolinska Institutet provides insight on how the brain processes external input such as touch, vision or sound from different sources and sides of the body, in order to select and generate adequate movements. The findings, which are presented in the journal Neuron, show that the striatum acts as a sensory ‘hub’ integrating various types of sensory information, with specialised functional roles for the different neuron types.
