Deep in a South African gold mine, three kilometers below the Earth's surface, scientists have discovered a tiny ecosystem in which there is only one organism.

As the world's climate changes, many species are being forced out of their old habitats. While some species are able to migrate to cooler territory, those in the tropics may have no where else to go.

Scientists have retraced the century-old steps of legendary naturalist Joseph Grinnell through Yosemite National Park. They found that most species have moved to higher, cooler elevations. Their study is published in this week's issue of the journal Science.

To improve aircraft operator performance, the military have invested a good deal of money into neuroscience and behavioral research. The models and simulations can tell them a lot about human weaknesses in multitasking and how to use technology to improve.

Many teens today bounce between computers, music, cell phones and homework. They might appear superproductive, but science says otherwise: Every time we switch tasks, the brain shuts down connections to key information.

Two Americans and a Japanese researcher have won the 2008 Nobel Prize in chemistry for the discovery of a glowing jellyfish protein. This enables scientists to study the previously invisible machinery of life in action and is used by researchers around the world.

A University of Chicago professor won a share of the Nobel Prize in physics Monday. Yoichiro Nambu, a Tokyo-born U.S. citizen, shares the prize with two Japanese scientists. Nambu gets half the prize for the discovery of spontaneous broken symmetry in subatomic physics.

The 2008 Nobel Prize for physiology or medicine went in part to two French researchers for discovering the virus that causes AIDS. The award was not shared by American Robert Gallo, who has also claimed a role in the discovery of HIV. Additionally, a German scientist got the prize for establishing the cause of most cervical cancers.

The financial bailout President Bush signed last week actually began its legislative life as a bill addressing mental health benefits. The law intended to save Wall Street also requires many businesses to offer mental health coverage equal to that for other illnesses.

The 2008 Nobel Prize for physiology or medicine goes to two French scientists for discovering the virus that causes AIDS. A German researcher shares the prize for discovering the viruses that cause cervical cancer.

When a swarm of bees takes flight, it can form a cloud as big as a school bus. But who's driving? And how do they know which way to go? Professor Thomas Seeley of Cornell University talks about how swarms of honeybees decide who's at the wheel and who's a backseat flier.

The iJET is a new type of solar cell that's cheap and easy to make, requiring not much more than a pizza oven, some nail polish remover, and a common inkjet printer. Australian scientist Nicole Kuepper describes her invention.

When Andrea St. John and Kevin Broderick met in 2006, they were both teaching high school in Lake Placid, N.Y. Broderick was in recovery from a rare form of cancer. But that didn't stop them from falling in love. Recently, St. John spoke with Broderick's brother about their relationship.

A recent study found that volunteers conditioned to feel a lack of control were more likely to see patterns that didn't exist. Faced with powerlessness, the human mind seems to make up patterns to explain the world around it.

SpaceX's flagship Falcon1 rocket has successfully launched from an island in the central Pacific, becoming the first privately-developed rocket to orbit the planet. NASA has already contracted SpaceX to begin private space flight missions to the International Space Station beginning in 2010.

New research shows that when people perceive they have no control over a given situation, they are more likely to see illusions, patterns where none exist and even believe in conspiracy theories. The study suggests that people impose imaginary order when no real order can be perceived.

A consortium of Northeast states has completed the first cap-and-trade greenhouse gas auction in the U.S. Under cap-and-trade, limits are set on emissions. Companies that do not use up their quota of emissions are able to sell their excess emission capacity to other companies.

NASA has postponed a planned repair mission to the Hubble Space Telescope after a new problem developed with the orbiting observatory. Ed Weiler, associate administrator of the Science Mission Directorate at NASA, explains why repairs won't take place until Feb. 2009 — at the earliest.

Ever wonder how a song gets stuck in your head? Neurologist Oliver Sacks explains this and other mind-music mysteries in his new book, Musicophilia.

Don't believe the multitasking hype, scientists say. New research shows that we humans aren't as good as we think we are at doing several things at once — but it also found a skill that gives us an evolutionary edge. Researchers say humans are merely very good at switching their attention from task to task.

The recent discovery of a well-preserved tissue sample from a woman living in the Congo in 1960 allowed scientists to analyze an early version of the HIV genome. Their findings indicate that HIV arrived in the region much earlier than previously thought, around 100 years ago.

Voting is your civic duty, but be careful how you get to the polls. A new study suggests that there is an increased risk of car crashes on presidential voting days.

Are the candidates healthy enough to serve in the job they're gunning for? John McCain allowed reporters to look at — but not photocopy — more than a thousand pages of health records last May. Barack Obama provided a one-page summary from his doctor.

Tests for cancer are intimidating enough — and now genetic tests can reveal a patient's predisposition for certain cancers before there are any symptoms. Filmmaker Joanna Rudnick, upon learning she had such a genetic mutation, made a TV documentary about the agonizing choices such tests involve.

Shoppers will soon see more food labels with the country of origin. A new law goes into effect Tuesday aimed at giving U.S. consumers more information about where their meat and produce come from. But globalization has made things more complicated. A hog may have been born in Canada but raised and slaughtered in the U.S.

Many people generate an immense amounts of digital data during a single day — often without a second thought. But Stephen Baker, a senior writer at BusinessWeek, warns that the information generated is being monitored by a group of entrepreneurial mathematicians.

Rep. Jim McDermott (D-WA) serves a dual role in Washington these days: he's not just a congressman, but he's also calling upon his experience as a former psychiatrist. Lawmakers struggling with the stress of their jobs have asked for his advice recently. McDermott talks to host Andrea Seabrook about dealing with Capitol Hill pressures.

Vitamin D is essential for strong bones. Our bodies use sunlight to create their own vitamin D. Bruce Hollis, a professor at the Medical University of South Carolina, talks about how the process works.
