25 years of DNA on the computer

For about 20 years now, experimental research on nuclear DNA has been supplemented by research based on computer simulations aimed at reconstructing the structure and function of this molecule that is so essential to life as we know it. A systematic review - carried out with the participation of SISSA in Trieste - provides a detailed summary of the majority of models developed to date. The review is mainly aimed at biologists, for whom it may become an important research tool.

Epigenetics enigma resolved

Scientists have obtained the first detailed molecular structure of a member of the Tet family of enzymes. The finding is important for the field of epigenetics because Tet enzymes chemically modify DNA, changing signposts that tell the cell's machinery 'this gene is shut off' into other signs that say 'ready for a change'.

Scientists reduce protein crystal damage, improve pharmaceutical development

Researchers at the US Department of Energy's Argonne National Laboratory, in collaboration with two other institutions, have identified a method for protein crystallography that reduces damage to the protein crystal. This will allow crystals to be studied for longer periods of time as researchers study protein structures for new pharmaceuticals.
