　　The Galleon trial

　　Rajaratnam guilty as charged

　　IN A phone call recorded by the government in 2008, Raj Rajaratnam, the boss of Galleon Group, a large hedge fund, called Danielle Chiesi, an executive at another fund, to thank her for sharing a tip. “But it’s a conquest, right?” he asks her. “It’s a conquest,” she responds. “You’re a warrior. I’m a warrior.”

　　On May 11th Mr Rajaratnam lost the battle he was fighting against government prosecutors. He was convicted on 14 counts of securities fraud and conspiracy, and faces up to 205 years in prison when he is sentenced in July. A New York jury found that Mr Rajaratnam made nearly $64m from trading based on tips he ferreted out from a network of corporate executives and traders about firms like Goldman Sachs, Google and Intel. He rewarded them generously for confidential information. He paid Anil Kumar, then an executive at McKinsey, $500,000 a year for tips about the firm’s clients, for example.

　　This is the first insider-trading case in which the government has used wiretaps, and they were pivotal in Mr Rajaratnam’s conviction. The jury heard dozens of conversations that showed him as foul-mouthed, boastful and conniving. In one Mr Rajaratnam and his brother, Rengan, talk about getting another McKinsey executive to leak information. “Everybody is a scumbag,” says Rengan, and they...

　　Deep-sea vents　Ocean-floor migration

　　How surface winds blow deep-sea critters from vent to vent

　　EVER since their discovery in the 1970s, deep-sea vents—chimney-like structures on the ocean floor that belch hot water and dissolved minerals into the surrounding ocean—have been one of the hottest topics in marine biology. The vents support populations of bacteria, giant worms, clams, shrimp and other creatures in the inky darkness, often several kilometres below the surface. Unlike virtually every other ecosystem on the planet, these deep-sea communities do not rely on the sun for their food. Instead of using photosynthesis, the bacteria at the bottom of the food chain harvest energy from chemicals supplied by the vents themselves.

　　The vents are both widely spaced and transient, which means their denizens live a precarious existence. Yet travel between vent systems is apparently possible, even across miles of desolate ocean floor. Creatures confined to islands rapidly head in a different genetic direction to mainland relatives; but researchers have found surprisingly little genetic variation between the populations of even quite widely spaced ocean-bottom vents. Last year one paper described how a vent system that had been wiped clean by a volcanic eruption was quickly recolonised by a variety of larval creatures, some of which seemed ...
