New York Times: A Russian cargo spacecraft, Progress-M, failed to dock with the International Space Station on Tuesday when the craft’s new autopilot malfunctioned. The setback was not serious, however, as Progress-M had already docked once and unloaded its supplies. The second attempt was a practice run with the new hardware. If a third attempt on Sunday fails, the craft will return to Earth, where engineers will work to solve the problem. Tuesday’s glitch is the latest in a string of problems suffered recently by Russian spacecraft. The crash of a Russian rocket last summer worried the US, especially because NASA astronauts have flown on similar rockets to reach the space station.

Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
