It seems chimps can have a common culture yet also their own local traditions. Does this mean chimpanzees in Asia would learn to use chopsticks?

Yes, says a study released today, if they saw other groups doing it.

The study confirms captive chimpanzees have the capacity to sustain the same kind of multiple-tradition cultures many researchers believe exist in the wild, providing further evidence chimpanzees and humans shared a common ancestor five to six million years ago who had a similar level of cultural complexity.

MIT researchers were recently able to light a 60W light bulb from a power source seven feet away; there was no physical connection between the source and the appliance.

The MIT team refers to its concept as “WiTricity” (as in wireless electricity). Various methods of transmitting power wirelessly have been known for centuries and perhaps the best known example is radio waves. While such that sort of electromagnetic radiation is excellent for wireless transmission of information, it is not feasible to use it for power transmission.

Think you know how to solve global warming? You'll soon get a chance to find out.

A new Web-enhanced version of the most commonly used climate modeling system will allow scientists, students or anyone else to test their theories about the planet's climate. The Community Climate System Model is already used by thousands of scientists, and the results from their models often make headlines around the world.

The Japanese are a polite people. If your host on a trip is Japanese they often make you feel like you are the most important person in the world. Low self esteem? Awe of your culture?

No, they have very high self-esteem and probably feel superior, a study says. Being nice to you may be just another way to prove it.

Surveying 500 students from three countries, the study used a test (Implicit Association Test (IAT)) created by University of Washington psychologist Anthony Greenwald and found that self-esteem was very positive among students from each of the nations. The consistency of the results across cultures was so clearly apparent that the researchers conclude that high self-esteem may be universal.

The relative amount of protein, carbohydrate, and fat that people choose to eat may be influenced by genetics, according to new research.

Jose Ordovas, PhD, director of the Nutrition and Genomics Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (USDA HNRCA), and colleagues found that the apolipoprotein A-II gene (APOA2) is associated with proportions of fat, carbohydrate, and protein in the diet, along with total calories and, therefore, with body-mass-index (BMI). These results are the first to show that the APOA2 gene is linked to food preferences that shape dietary patterns, particularly preferences for dietary fat.

Extracts of the hemp plant cannabis are traditionally used as a popular remedy against inflammation. At the beginning of the last century this natural remedy was even available at every chemist’s. But due to the intoxicating effect of the component THC (tetrahydrocannabinol) the plant was taken off the chemist’s shelves in the 1930s.

Scientists from the University of Bonn have discovered in experiments with mice that Endocannabinoids play an important role in regulating inflammation processes.
