Learning from nature: Scientists break down carbon dioxide into carbon monoxide using visible light

Wed, 10 Mar 2010 04:24:15 GMT

― Learning from nature: Scientists break down carbon dioxide into carbon monoxide using visible light [sciencedaily.com]
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.

― 'The Rosenfeld' named after California's godfather of energy efficiency [sciencedaily.com]
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.

New study questions benefits of elective removal of ovaries during hysterectomy

Wed, 10 Mar 2010 04:24:10 GMT

― New study questions benefits of elective removal of ovaries during hysterectomy [sciencedaily.com]
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.

Obesity as protection against metabolic syndrome, not its cause

Wed, 10 Mar 2010 04:24:09 GMT

― Hemoglobin A1c outperforms fasting glucose for risk prediction [sciencedaily.com]
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.

After a fight with a partner, brain activity predicts emotional resiliency

― After a fight with a partner, brain activity predicts emotional resiliency [machineslikeus.com]
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 Unveils Next Internet Core Router [osnews.com]
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.

Study finds cancer mortality has declined since initiation of 'war on cancer'

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.

Sources of pollution in waterways

Tue, 09 Mar 2010 22:00:05 GMT

― Sources of pollution in waterways [physorg.com]
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...
