A recent discovery in understanding how to chemically break down the greenhouse gas carbon dioxide into a useful form opens the doors for scientists to wonder what organism is out there -- or could be created -- to accomplish the task. Scientists have figured out a way to efficiently turn carbon dioxide into carbon monoxide using visible light, like sunlight.

Pioneering French physicists Marie and Pierre Curie have the curie, a unit of radioactivity, named after them. Renowned inventor Nikola Tesla is honored with the tesla, which measures a magnetic field. And now, the Rosenfeld, proposed as a unit for electricity savings, will be named after the man seen by many people as the godfather of energy efficiency, Arthur Rosenfeld.

For all those dismayed by scenes of looting in disaster-struck zones, whether Haiti or Chile or elsewhere, take heart: good acts -- acts of kindness, generosity and cooperation -- spread just as easily as bad. And it takes only a handful of individuals to really make a difference.

In the future, getting a broadband connection might be as simple as flipping on a light switch. In fact, according to a group of researchers from Germany, the light coming from the lamps in your home could one day encode a wireless broadband signal.

Scientists have found evidence of a catastrophic event they believe was responsible for halting the birth of stars in a galaxy in the early universe. The researchers observed the massive galaxy as it would have appeared just three billion years after the Big Bang when the Universe was a quarter of its present age.

Removal of the ovaries (bilateral oophorectomy) while performing a hysterectomy is common practice to prevent the subsequent development of ovarian cancer. This prophylactic procedure is performed in 55% of all U.S. women having a hysterectomy, or approximately 300,000 times each year. A new article suggests that this procedure may do more harm than good.

Measurements of hemoglobin A1c (HbA1c) more accurately identify persons at risk for clinical outcomes than the commonly used measurement of fasting glucose, according to a new study. HbA1c levels accurately predict future diabetes, and they better predict stroke, heart disease and all-cause mortality as well.

Consider this T-shirt: It can monitor your heart rate and breathing, analyze your sweat and even cool you off on a hot summer's day. Or a solar-powered dress that can charge your MP3 player? This is not science fiction -- this is cotton in 2010.

A few hours before Google officially announced its Apps Marketplace, I had a chance to interview someone at Google and a partner company about the announcement. They offered a more details about the news, and also hinted at where the marketplace going from here. Again, the Apps Marketplace is an online store for outside companies to sell applications that integrate with Google Apps, the search giant’s bundle of office apps including Gmail and Google Docs. Thanks to protocols like OAuth and...

The humble papaya is gaining credibility in Western medicine for anticancer powers that folk cultures have recognized for generations.

Common wisdom tells us that for a successful relationship partners shouldn't go to bed angry. But new research from a psychologist at Harvard University suggests that brain activity—specifically in the region called the lateral prefrontal cortex—is a far better indicator of how someone will feel in the days following a fight with his or her partner.

Cisco Systems today introduced its next-generation Internet core router, the CRS-3, with about three times the capacity of its current platform. "The Internet will scale faster than any of us anticipate," Cisco Chairman and CEO John Chambers said during a webcast announcing the product. At full scale, the CRS-3 has a capacity of 322Tbit/sec., roughly three times that of the CRS-1, which was introduced in 2004. It also has more than 12 times the capacity of its nearest competitor, Chambers said.

University of Minnesota researcher George Weiblen and colleagues have found a faster way to study the spread and diet of insect pests.

Sonic hedgehog, a gene that plays a crucial rule in the positioning and growth of limbs, fingers and toes, has been confirmed in an unexpected place in the embryos of developing mice -- the layer...

A hospitalist at the University of Rochester Medical Center calls for more stringent Federal guidelines governing the approval of potential new drugs, in a commentary in the March 10 issue of the Journal of the American Medical Association.

A new American Cancer Society study finds progress in reducing cancer death rates is evident whether measured against baseline rates in 1970 or in 1990. The study finds a downturn in cancer death rates since 1990 results mostly from reductions in tobacco use, increased screening allowing early detection of several cancers, and modest to large improvements in treatment for specific cancers.

Polycyclic aromatic hydrocarbons (PAHs) are components of petroleum products such as gasoline, coal, and oil. They are also produced as by-products of the combustion of fuels including petroleum and fire wood. PAHs can cause cancer and other health effects. Because they are produced during combustion, they are ubiquitous, and their levels are high enough to be a concern in all urban waterways. However, because there are so many potential sources of PAHs in the environment, it is not clear...

After more than three decades of service to researchers and staff stationed at the bottom of the world, the dome at the Amundsen-Scott South Pole Station was deconstructed this austral summer.

Patients with irritable bowel syndrome are at no greater risk of having polyps, colon cancer or inflammatory bowel diseases than healthy people undergoing colonoscopies, according to new research published in the American Journal of Gastroenterology.

Forecasters are watching a low pressure area located off the east coast of Madagascar that appears ripe for development in the Southern Indian Ocean. If it becomes a tropical storm, it would be named Hubert.
