Yale researchers have described how dueling brain systems may explain why you forget to drop off the dry cleaning and may point to ways that substance abusers and people with obsessive compulsive disorder can overcome bad habits.
 
In Proceedings of the National Academy of Sciences, Christopher J. Pittenger, M.D., and colleagues describe a sort of competition between areas of the brain involved in learning that results in what Pittenger calls the “dry cleaning effect.”
 
One area of the brain called the striatum helps record cues or landmarks that lead to a familiar destination. It is the area of the commuter’s brain that goes on autopilot and allows people to get to work, often with little memory of the trip.
 

Researchers in Germany are describing a potential alternative to Botox and cosmetic surgery for easing facial wrinkles. Their study, scheduled for the November 5 issue of ACS' Crystal Growth&Design,  reports that high intensity visible light from light emitting diodes (LEDs) applied daily for several weeks resulted in "rejuvenated skin, reduced wrinkle levels, juvenile complexion and lasting resilience."

LEDs, if you're not a regular reader here (though you should be) are the miniature lights used in an array of products, from TV remote controls to traffic lights.

Using more coal won't solve greenhouse gas issues but it buys time for clean energy to become cost- and energy-effective.  Our coal supply, unlike oil, will last for hundreds of years .

Scientists in Italy are reporting that a new process could eliminate key obstacles to the expanded use of coal gasification to transform that abundant domestic energy resource into synthetic liquid fuels for cars and trucks. The study is scheduled for the November 19 issue of  Energy&Fuels.

Over the past 30 years, the U.S. population has reduced its fat intake and increased its consumption of carbohydrates. During the same time period, obesity has been rising along with the prevalence of metabolic liver disease in which fatty deposits in the liver can lead to inflammation, fibrosis and cirrhosis. Some studies have suggested that a high carbohydrate diet leads to fat formation in the liver, although confirming the association has been difficult.

When carbohydrates are restricted, the liver relies more on substances like lactate and amino acids to form glucose, instead of glycerol. These findings are in the November issue of Hepatology.

In the human world , some humans try to bank money to obtain financial security and occasionally form groups to reduce risks and increase gains.

Regardless of well-known financial wisdom, some people still end up in 'poverty traps', where because of fewer resources and an increasingly high cost of living they find themselves unable to increase their quality of life.  

Researchers at Wake Forest University School of Medicine may be one step closer to understanding why past oral contraceptive use dramatically lowers the risk of ovarian and uterine cancers later in life. 

While studying the effect of post-menopausal dietary soy consumption on estrogen metabolism in cynomolgus monkeys, Latanya M. Scott, Ph.D., discovered that monkeys who had been given birth control earlier in life had a reduced amount of estrogen excreted in their urine. The research was done in collaboration with Xia Xu, Ph.D., and Timothy Veenstra, Ph.D. at Science Applications International Corporation-Frederick, Inc., in Frederick, Md., who have developed novel methods for analysis of urinary estrogens. 

What do presidential candidate Barack Obama and Snapple Iced Tea have in common? Patricia Turner, professor of African American and African studies at the University of California, Davis, whose research focuses on urban legends and conspiracy theories, notes that Snapple had to grapple with two false rumors when it became a sensation in 1993.


Did you ever hear that Snapple has ties to pro-life extremists or that it was owned by the Ku Klux Klan?  We haven't either but apparently that's what some people said and some people believed. 

Did you know there was such a thing as 'Quantum Darwinism'?  Indeed there is, and it postulates the theory that quantum mechanical states are selected and reproduced.

Theoretical proof of stable and measurable states extending over two quantum dots and creating offspring has now been provided, say researchers at the Institute of Physics at the University of Leoben, together
with colleagues from the Arizona State University. This supports the notion of what is known as Quantum Darwinism, which makes the selection and reproduction of quantum mechanical states responsible for the
way in which our reality is perceived.
