Has US learned the lesson of Enron 10 years later? (AP)
AP - From humble origins as a natural gas distributor, Enron became a trading operation with the Midas touch. It made bets on oil, water, Internet traffic, even the weather. Wall Street's brightest worked there. Its stock tripled in two years.

A vaccination against social prejudice
Evolutionary psychologists suspect that prejudice is rooted in survival: Our distant ancestors had to avoid outsiders who might have carried disease. Research still shows that when people feel vulnerable to illness, they exhibit more bias toward stigmatized groups. But a new study suggests there might be a modern way to break that link.

23:42A drop in carbon dioxide appears to be the driving force that led to the Antarctic ice sheet's formation, according to a recent study of molecules from ancient algae found in deep-sea core samples.

23:42A new study may help explain why men are three times more likely than women to develop a common form of skin cancer. The study found that male mice had lower levels of an important skin antioxidant than female mice and higher levels of certain cancer-linked inflammatory cells. As a result, men may be more susceptible to oxidative stress in the skin, which may raise their risk of skin cancer compared to women.

23:42We don't see only what meets the eye. The visual system constantly takes in ambiguous stimuli, weighs its options, and decides what it perceives. This normally happens effortlessly. Sometimes, however, an ambiguity is persistent, and the visual system waffles on which perception is right. Such instances interest scientists because they help us understand how the eyes and the brain make sense of what we see.

23:42In many fields of applied science, such as geology, there are often tensions and disagreements between scientists who specialize in analyses of problems using mathematical models to describe sets of collected data, and those that rely on on-the-ground observations and empirical analyses.

'Moment of truth' approaching in Higgs boson hunt
The beginning of the end, or the end of the beginning, looms for the elusive particle -
23:26Reuters - Volkswagen AG's new assembly plant in Chattanooga, Tennessee, is the first auto plant to receive the top environmental award from the U.S. Green Building Council, the company said on Thursday.

Adult stem cells use special pathways to repair damaged muscle (w/ Video)
When a muscle is damaged, dormant adult stem cells called satellite cells are signaled to "wake up" and contribute to repairing the muscle. University of Missouri researchers recently found how even distant satellite cells could help with the repair, and are now learning how the stem cells travel within the tissue. This knowledge could ultimately help doctors more effectively treat muscle disorders such as muscular dystrophy, in which the muscle is easily damaged and the patient's satellite cells have lost the ability to repair. -
23:24There's an existential crisis that often happens at dinner tables across the country: why won't kids eat their vegetables? Research has found that one reason could be a sensitivity to bitterness, fairly common among children – about 70 percent have it.

23:24A group of Muslim businessmen unveiled plans in Turkey on Thursday for a Facebook-style social networking site with "healthy values" for a young, Islamic audience.

23:24(AP) -- A federal appeals court ruled Thursday that most bone marrow donors can be paid, overturning a decades-old law that made such compensation a crime.

23:24People with obstructive sleep apnea are more likely to stick to prescribed treatment when a partner or parent is involved with their treatment, according to a team of sleep researchers.

23:24Nearly two-thirds of Israeli Jews, 64 percent, favor establishing a nuclear free zone in the Middle East - even when it was spelled out that this would mean both Israel and Iran would have to forego nuclear weapons - finds a new University of Maryland poll. The research is a joint project of the Anwar Sadat Chair at the University of Maryland and the Program on International Policy Attitudes (PIPA).

23:24(AP) -- After years of decline, measles is on the rise in Europe, according to a new report released Thursday.

23:24A team of scientists have used the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite to confirm major reductions in the levels of a key air pollutant generated by coal power plants in the eastern United States. The pollutant, sulfur dioxide, contributes to the formation of acid rain and can cause serious health problems.

23:24In a development that could pave the way for treatment for rare neurological diseases and clues to more common ones, physician-scientists at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center, the University Hospital for Einstein, have secured a grant to establish a clinical site for the Network for Excellence in Neuroscience Clinical Trials (NeuroNEXT). One of only 25 such federally-funded centers in the country, the Einstein-Montefiore site was created in partnership with Einstein affiliates Beth Israel Medical Center in Manhattan and the North Shore-Long Island Jewish Health System. The NeuroNEXT network and its centers were established with grants from the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.

23:24One major obstacle in the fight against cancer is that anticancer drugs often affect normal cells in addition to tumor cells, resulting in significant side effects. Yet research into development of less harmful treatments geared toward the targeting of specific cancer-causing mechanisms is hampered by lack of knowledge of the molecular pathways that drive cancers in individual patients.

22:36Close to 70 percent of children have a sensitivity to bitter tasting foods, and that can cause them to avoid many of the leafy, green vegetables they should be eating for healthy development. But new research has found that adding a small amount of dip can help children with this sensitivity eat more of their vegetables.
