A combination of protein crystallography and biochemistry has revealed how a ring-shaped helicase might trap a single DNA strand as the double helix melts, and before it is unwound.

Environments for computer-aided composition (CAC), allowing generation and transformation of symbolic musical data, are usually counterposed to real-time environments or sequencers. The counterposition is deeply methodological: in traditional CAC environments interface changes have no effect until a certain ‘refresh’ operation is performed whereas real-time environments immediately react to use...

Unwind-protect in portable Scheme

Programming languages that allow non-local control jumps also need to provide an unwind-protect facility. Unwind-protect associates a postlude with a given block B of code, and guarantees that the postlude will always be executed regardless of whether B concludes normally or is exited by a jump. This facility is routinely provided in all languages with first-order control operators. Unfortunate...
