Maurice Michel is the 2023 winner of the Eppendorf Award for Young European Investigators. He is an assistant professor in the Science for Life Laboratory, Karolinska Institutet, Stockholm. Michel’s work has shown that a small molecule binding to the ac
DNA (or its sister molecule RNA) has now won Nobel prizes at least eight times: 1962This was the big one,the discovery of the structure of DNA, awarded to Francis Crick, James Watson and Maurice Wilkins 1980Forrecombinant DNA 1989This was forshowing how RNA catalyses reactions ...
An enzyme is a protein that speeds up a particular chemical reaction. For example, one of the 1,000 enzymes in an E. coli's DNA might know how to break a maltose molecule (a simple sugar) into its two glucose molecules. That is all that that particular enzyme can do, but that actio...
But now Google DeepMind has gone a step further, unveiling AlphaProteo, a new AI model that can design a protein that will bind to any target molecule. AlphaProteo is likely to have a direct impact on drug design, enabling researchers to more easily create new protein-based therapies, and ...
Fransen: What we see is that the joy of working in health care is not that big anymore. People are leaving because the huge pressure.7 Pre COVID-19, we’d seen people were under a lot of pressure and now they still are. So you see people leaving because they are not ...
