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.

Researchers at Georgetown University Medical Center and the National Institutes of Health (NIH) have, for the first time, used a “bionic” ear to restore hearing in a patient with von Hippel-Lindau disease.

The disease, caused by inheritance of a mutated tumor suppressor gene, occurs in 1 out of 36,000 live births, and about 30 percent of these patients develop tumors in their ears − often in both. To date, the only option to help control these tumors is repeated surgery, which is often not successful, he said. Loss of hearing is sudden, and hearing aids don’t help, Kim said.

On the eve of World Oceans Day, a group of over 100 scientists from 15 countries has revealed new evidence for the declining state of Europe's 4 regional seas

Their models developed during a €2.5M EU funded research project have predicted dire consequences for the sea unless European countries take urgent action to prevent further damage from current and emerging patterns of development. The project coordinator, Professor Laurence Mee, Director of the Marine Institute at the University of Plymouth said “Europeans are just beginning to wake up to the fact that the area of their seas is bigger than the land and that it is already seriously degraded.

Is ADHD over-diagnosed? Claims vary, with some people stating that ADHD prescriptions are substituting for parenting and teaching. No matter your opinion, ADHD medication is in greater use than ever and not just for children.

A recent study shows that treatment rates have been increasing in all age groups, and improved identification has contributed to rapidly growing treatment rates for adults. Female patients show the greatest increase of all.

The study, Trends in Medication Treatment for ADHD, revealed rapid growth of ADHD medication use in all demographic groups except seniors, with some groups showing markedly faster rates than others.
