WEEKLY e-LETTER from SCIENCE NEWS
February 28, 2004
Subject: Science News Weekly e-letter
A recipe for superhard diamonds, coin tossing with a bias, an astronomical hint of dark energy, an overlap between music and language in the brain, and an epilepsy drug that limits migraine attacks are among the subjects of this week's news stories. The cover story focuses on some surprising findings about how body fat undermines health. Contorting silicon crystals to achieve faster electronics is the subject of a second feature article. Food for Thought looks at a special tea as an alternative to fluorescent lights for treating newborns who suffer from jaundice. MathTrek tackles the unfairness of coin tossing.

Toss Out the Toss-Up: Bias in heads-or-tails
Coin tossing is inherently biased, with the coin more likely to land on the same face it started on.

Averting Pain: Epilepsy drug limits migraine attacks
A drug normally used against epilepsy can prevent migraine headaches.

Straining for Speed: In search of faster electronics, chip makers contort silicon crystals
Hitting fundamental limits on how small they can make certain structures within semiconductor transistors, chip makers are deforming the silicon crystals from which those transistors are made to eke out some extra speed.
