Simple genetic circuit forms stripes

Many living things have stripes, but the developmental processes that create these and other patterns are complex and difficult to untangle. Now a team of scientists has designed a simple genetic circuit that creates a striped pattern tha [...]

Map of herpes virus protein suggests a new drug therapy

Most viruses need cell-entry proteins called fusogens in order to invade cells. We have known that the herpes virus fusogen does not act alone and that a complex of two other viral cell-entry proteins is always required. We expected [...]
