How can you lower your heart attack risk without losing weight?

A new and very rigorous study shows that a Mediterranean diet full of fresh fruits and vegetables, nuts, fish and olive oil can lower the risk of stroke and other serious heart trouble by 30 percent. The improvement was not linked to weight. The researchers followed some 7,500 people in Spain who were at risk for having heart problems for five years to see how dietary changes might help. Their findings were published online Monday by the New England Journal of Medicine.

Do Russian defendants have to appear in court?

Nope. They don't even have to be alive. The trial of Sergei Magnitsky, a lawyer for Hermitage Capital Management Ltd., which was once Russia's biggest foreign equity investor, is set to start next week. Magnitsky died in 2009 at the age of 37 while in pretrial detention after alleging committing the biggest known tax fraud in Russia, a theft of $230 million from the national treasury. The case sparked a diplomatic row, with the U.S. imposing sanctions on Russian officials accused of playing a role in Magnitsky's death, and Moscow retaliating by barring American citizens from adopting Russian orphans.

What strange creatures are washing up on the Washington state coast?

Though no one has seen such an explosion in the population of salps before, the suspicion is that it is a response to a sudden abundance of plankton triggered by climate change.
