Stiff Handling Of Genes The efficacy of materials for carrying genes into cells may be determined more by their stiffness than by their chemical properties.
Bacterial Trojan Horses New work identifies an important molecule to target against Brucella infections in both humans and animals.
RNA Enzymes Use Acid Researchers show how a RNA molecule from the hepatitis delta virus (HDV) uses an acidic group to accelerate a chemical reaction central to its life cycle.
Fat: The Big Picture Research identifies the network of genes required for early steps in the development of brown fat cells.
Molecule That Induces Tumour Regression A promising approach to eliminate cancer cells is to trigger cell death (apoptosis) with inhibitors that bind to and block anti-apoptotic proteins that help keep cancer cells alive.
