Gallbladder removal is one of the most common operations performed in older adults. Yet, research suggests that many patients who would benefit most from the surgery don't get it.

Two experimental DNA vaccines to prevent Ebola virus and the closely related Marburg virus are safe, and generated a similar immune response in healthy Ugandan adults as reported in healthy US adults earlier this year. The findings are from the first trial of filovirus vaccines in Africa.

New research indicates that shifts in Pacific trade winds played a key role in twentieth century climate variation and are likely again influencing global temperatures. The study uses a novel method of analyzing coral chemistry to reveal winds from a century ago.

Resveratrol, the red-wine ingredient once touted as an elixir of youth, powerfully activates an evolutionarily ancient stress response in human cells, scientists have found. The finding should dispel much of and controversy about how resveratrol really works.

Scientists have created a 'map' of the distribution of water vapor. Their research includes observations of seasonal variations in atmospheric concentrations using data collected over ten years by the Russian-French SPICAM spectrometer aboard the Mars Express orbiter. This is the longest period of observation and provides the largest volume of data about water vapor on Mars.

It's like a scene from a gamer's wildest dreams: 12 high-definition, 55-inch 3-D televisions all connected to a computer capable of supporting high-end, graphics-intensive gaming. On the massive screen, images are controlled by a Wii remote that interacts with a Kinnect-like Bluetooth device (called SmartTrack), while 3-D glasses worn by the user create dizzying added dimensions.

New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.
