Before the reels on a slot machine stop spinning, a gambler’s brain is already anticipating the potential rewards. And although two bananas on the pay line with a third just barely visible won’t pay a gambler any more than three random fruits, such near misses have the well-documented, if irrational, effect of enticing gamblers to try again. The reason, according to a new study, is that these near misses activate the same reward signals in the brain as a win.

The University of Cambridge rang in its 800th anniversary with church bells and a light show on Saturday the 17th. The light show, created by projection artist Ross Ashton, included specially commissioned illustrations of Cambridge alumni Charles Darwin and Isaac Newton by Roald Dahl’s illustrator, Quentin Blake. Above, a graying Darwin ponders the tree of life, whose branches recapitulate the origins of the species. Other images evoked the scientific, musical, and debaucherous achievements of 800 years of Cambridge students and alumni.

Some of us sing, and some of us just mouth the lyrics, but we all rely on our brain to coordinate even the simplest motor behaviors. Scientists interested in the brain activity behind motion often use birdsong as a model because certain songs are sung the same way every time, providing a naturally controlled setting for investigation. Now researchers have solved a long-standing mystery about the hierarchy of brain regions essential for birdsong using a chilly technique that could tease out the interconnected processes behind many complex actions.

LONDON–When scientists move into new laboratory buildings, their universities often proclaim the event with a ribbon cutting and champagne. Yet when the first mice arrived at the University of Oxford’s new animal research facility last week, officials waited to make the announcement until a press conference here today. Rather than enthusiastically providing details about the building’s inhabitants–animals and researchers included–Oxford officials spent much of the media encounter declining to answer questions and asking that names of those involved with the building not be used.
