Sleep cycles can affect an athlete's performance

If you watched Sunday's Super Bowl, you witnessed its improbable ending: Jermaine Kearse’s remarkable catch near the end; Seattle coach Pete Carroll's surprising play call at the goal line; and the interception that clinched the win for the New England Patriots. Would the outcome have been different had the game been played at a different time of day? We'll never know. But new research may provide an intriguing insight.

Science

Scientists have engineered a bacteria with a genetic 'kill switch'

"This device will self-destruct in 10 seconds: 10...9...8...7..." How many times have you seen that in an action or sci-fi thriller? Can you imagine that scenario involving bacteria? If not, it may be time to start: genetic engineers have created strains of bacteria designed to die on their own in the absence of a synthetic compound that does not exist anywhere in nature.

Music

How pop music helped save the whales

If you hear whale songs today, you might be getting a massage or a facial. Some recordings of humpback whales feature slow melodies — soothing enough for spa soundtracks. But not too long ago, in the early 1970s, the songs of whale songs ignited the passions of music listeners and animal activists, leading to a gold record for singer Judy Collins and a worldwide movement to save the whales.
