Buzz Off: Bedbugs Unfazed By Ultrasonic Devices

December 10, 2012 Once bedbugs settle in, the toll on your mental health and pocketbook can run high. So what about driving the bloodsucking insects off with high-pitched sounds? Scientists say gadgets that claim to do that are a waste of money.

Fruit Fly Nose Says Steer Clear Of Deadly Food; Human Nose Not So Reliable

Now we know why we'll never see a common fruit fly (Drosophila melanogaster) sitting on a beet.

December 6, 2012 Although we can usually smell when food goes bad, humans just don't have the fruit fly's direct path from nose to brain that alerts it to food poison. But the detection of this pathway could someday lead to more research that could help us develop better bug repellants.

Why It's Easier To Scam The Elderly

Fraud victims are more likely to have opened official-looking sweepstakes notices and other mailings. A new study says the elderly are more susceptible than the young to being swindled.

December 6, 2012 New research suggests older adults may have less activity in the area of the brain that processes risk and subtle danger. Another possible reason older adults don't pick up on warning signs is an increasing bias against negativity.

Victory Or Defeat? Emotions Aren't All In The Face

Can You Tell Emotion From Faces Alone? A new study suggests that when people evaluated just facial expressions — without cues from the rest of the body — they couldn't tell if the face was showing a positive or negative emotion. Enlarge this photo to see the answers.

November 30, 2012 Athletes may show intense emotion in their face, but you'll need more than that to tell if they won or lost. A new study suggests people don't read extreme facial expressions to judge how a person is feeling.

Greenland, Antarctic Ice Is Melting Faster

An iceberg that likely calved from Jakobshavn Isbrae, the fastest glacier in western Greenland.

November 29, 2012 The good news: Sea level has risen by just a half-inch in the past 20 years as a result of shrinking ice. The bad news: The melting is now speeding up. Over the next century, this could contribute to another 2- to 3-foot rise in sea level — enough to flood New York City every few years.

Space Probe Finds Ice In Mercury's Craters

Researchers say they have identified traces of ice in craters on Mercury, seen here in this Oct. 8, 2008, image from the Messenger spacecraft.

November 29, 2012 On the poles of our solar system's innermost planet, where temperatures can drop to -100 degrees Fahrenheit, researchers have identified water ice and organic "goo," most likely deposited there by comets that crashed into the planet.

A Short Fuse For Fusion As Ignition Misses Deadline

A worker inspects a huge target chamber at the National Ignition Facility in California, in 2001, where beams from 192 lasers are aimed at a pellet of fusion fuel in the hopes of creating nuclear fusion.

November 28, 2012 The $5 billion National Ignition Facility has been called a modern-day moonshot, a project of "revolutionary science." But the massive experiment that aims to generate nuclear fusion has failed to do so by a key deadline.

Do Orchestras Really Need Conductors?

Does This Guy Matter? Conductor Leonard Bernstein during rehearsal with the Cincinnati Symphony at Carnegie Hall in 1977.
