WHY DOES HAIR TURN GRAY?

Some people think, growing hair gray distinguish them from others.Some people think they are getting old. However scientists have tried to find an answer so many years.Finally they have come up with a theory.

Hair gets its color from a pigment called melanin, which is produced by melanocyte cells in the hair follicles. Researchers have discovered that melanocytes endure cumulative damage over the years, which eventually leaves them unable to produce melanin. Studies have cited DNA damage and a buildup of hydrogen peroxide in the follicles as possible causes of this disruption in melanin production. Without melanin, the new hair that grows in has no pigment, which makes it appear gray, white, or silver.

Some people start to go gray young. All most all the things in the body are usually determined by genes.This incident also determined by the genes.If your mother or father has started to go gray early their lives, You also have a chance to go gray early.However you can easily cover your gray with one of the many different hair dyes available.

How healthy is genetically modified soybean oil?

University of California-Riverside Soybean oil accounts for more than 90 percent of all the seed oil production in the United States. Genetically modified soybean oil, made from seeds of GM soybean plants, was recently introduced into the food supply on the premise that it is healthier than conventional soybean oil. But is that premise true? Just barely, say scientists. Researchers at the University of California, Riverside have tested a genetically-modified (GM) soybean oil used in restaurants and found that while it induces less obesity and insulin resistance than conventional soybean oil, its effects on diabetes and fatty liver are similar to those of conventional soybean oil.

Researchers have known for decades that fevers in the first trimester of pregnancy increase risk for some heart defects and facial deformities such as cleft lip or palate. But they have not known the reason for those defects.They thougt it was due to the root cause of the fever.It may be virus or bacteria. Recently researchers of the Duke University Medical Center has found that fever it self cause those defects and it does not depend on the root cause. Fever in first three to eight weeks of pregnancy can interfere with the development of heart and face of the fetus.According to results of the research they suggest a portion of congenital birth defects could be prevented by lowering the mother's fever with the judicious use of acetaminophen during the first trimester.Some Non Steroidal anti-inflammatory Drugs(NSAIDs) like ibuprofen and aspirin can also reduce the fever, but they have some adverse effects on late stages of the pregnancy.So those drugs are not good for use.
