Smart doesn't mean rich

It doesn't take a rocket scientist to make a lot of money, according to new research.

A nationwide study found that people of below average intelligence were, overall, just about as wealthy as those in similar circumstances but with higher scores on an IQ test.

Furthermore, a number of extremely intelligent people stated they had gotten themselves into financial difficulty.

"People don't become rich just because they are smart," said Jay Zagorsky, author of the study and a research scientist at Ohio State University 's Center for Human Resource Research.

Study says food advertising increases obese children's appetite by 134 percent

Obese and overweight children increase their food intake by more than 100% after watching food advertisements on television; a study by the University of Liverpool psychologists has shown.

Regenerative medicine - self healing organs on the road map

Findings described in a new study by Stanford scientists may be the first step toward a major revolution in human regenerative medicine—a future where advanced organ damage can be repaired by the body itself. In the May 2007 issue of The FASEB Journal, researchers show that a human evolutionary ancestor, the sea squirt, can correct abnormalities over a series of generations, suggesting that a similar regenerative process might be possible in people.

Can complicated structures re-evolve?

Lizards gave rise to legless snakes. Cave fishes don’t have eyeballs. In evolution, complicated structures often get lost. Dollo’s Law states that complicated structures can't be re-evolved because the genes that code for them were lost or have mutated. A group of sea snails breaks Dollo’s law, Rachel Collin, Staff Scientist at the Smithsonian Tropical Research Institute and colleagues from two Chilean universities announce in the April, 2007, Biological Bulletin.Smaller males on top of larger females.

Melatonin can delay aging, study says

The Spanish Aging Research Network (Red Nacional de Investigación del Envejecimiento), funded by Carlos III Health Institute and headed by professor Darío Acuña Castroviejo, from the University of Granada (Universidad de Granada [http://www.ugr.es]), is very near to achieving one of today's Science greatest goals: allowing humans to age in the best possible health conditions.

Europe's Obesity Epidemic

Europe is facing a “major health and social burden” as the obesity epidemic reaches crisis point, experts warned today.

Governments, whose health ministers have already signed the ‘European Charter’ pledging to halt the rise in obesity by 2015, must now back more intensive research programmes, and gear up to cope with the scale of the epidemic, which is damaging quality of life and reducing life expectancy.

Does age of womens' first menstruation influence their child's obesity risk?

Early menarche tends to be preceded by rapid infancy weight gain and is associated with increased childhood and adult obesity risk. As age at menarche is a heritable trait, we hypothesised that age at menarche in the mother may in turn predict her children's early growth and obesity risk.

Methods and Findings

Obtaining valid consent for doing large genetic studies in developing countries

Genomic research has the potential to improve global health by elucidating basic mechanisms of disease, susceptibility, and resistance, thereby guiding the development of preventive interventions [1]. Recently developed methods for exploring how human genetic variation affects resistance are likely to provide strategic clues about vaccine development for researchers working on malaria, HIV, tuberculosis, and other diseases of the developing world [2].

Ethnic differences in sensitivity to chemotherapy

Why do east Asian lung cancer patients respond better to chemotherapy than other ethnic groups? The answer could be useful in tailoring cancer treatments to individual patients.

"Genetic differences may help explain why so many Asian women who never smoked develop lung cancer," said Dr. Adi Gazdar, professor of pathology at UT Southwestern and senior author of a study appearing online today in Public Library of Science Medicine.

Prostate treatments versus quality of life

A rigorous, long-term study of quality of life in patients who underwent one of the three most common treatments for prostate cancer found that each affected men's lives in different ways. The findings provide invaluable information for men with prostate cancer who are facing vital treatment decisions.

Junk DNA or powerful gene regulator?

Large swaths of garbled human DNA once dismissed as junk appear to contain some valuable sections, according to a new study by researchers at the Stanford University School of Medicine and the University of California-Santa Cruz. The scientists propose that this redeemed DNA plays a role in controlling when genes turn on and off.

More phosphorous, less mercury

Research led by Dartmouth scientists found that animals fed nutritious, high-quality food end up with much lower concentrations of toxic methylmercury in their tissues. The result suggests ways in which methylmercury—a neurotoxin that can accumulate to hazardous levels—can be slowed in its passage up the food chain to fish.

Gene can activate anti-obesity hormone

A relative of the anti-aging gene Klotho helps activate a hormone that can lower blood glucose levels in fat cells of mice, making it a novel target for developing drugs to treat human obesity and diabetes, UT Southwestern Medical Center researchers have found.

The emerging fate of the Neanderthals

For nearly a century, anthropologists have been debating the relationship of Neanderthals to modern humans. Central to the debate is whether Neanderthals contributed directly or indirectly to the ancestry of the early modern humans that succeeded them.

Antioxidant in red wine kills leukemia cells

A naturally occurring compound found in many fruits and vegetables as well as red wine, selectively kills leukemia cells in culture while showing no discernible toxicity against healthy cells, according to a study by researchers at the University of Pittsburgh School of Medicine. These findings, which were published online March 20 in the Journal of Biological Chemistry and will be in press on May 4, offer hope for a more selective, less toxic therapy for leukemia.
