Read moreProteins are the molecular building blocks and machines of the cell and are involved in virtually every process of life. After protein production, many proteins are equipped with attachments such as sugar residues in order to perform their tasks properly. This process is directly coupled to the transport across a membrane. Employing various methods of structural biology, scientists have now gained insights into the architecture of the protein complex responsible for this process.

Read moreWhen autologous, skin-derived stem cells were transplanted within collagen nerve guide tubes aimed at bridging gaps in damaged nerves, into the upper arms of a patient who was suffering peripheral nerve damage, the procedure successfully led to the rescue of peripheral nerves. The procedure spared the patient with poly-injury to motor and sensory nerve damage from amputation of the upper arms and resulted in 'suitable functional recovery'. Three year follow up revealed nerve regeneration.

Read moreFor 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.

Read moreScientists 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'.
