(Phys.org) -- Scientists do not fully understand how nature uses proteins to develop new materials and minerals, but learning more about the natural processes could lead to bioengineering methods such as the biological synthesis ...
The cells of female mammals have a dosage problem, because they have twice as many X chromosomes as are needed in the body. Consequently, one of them is randomly selected and switched off already during early embryonic development. ...
