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.

Babies are born to dance, new research shows

University of York The findings, based on the study of infants aged between five months and two years old, suggest that babies may be born with a predisposition to move rhythmically in response to music. The research was conducted by Dr Marcel Zentner, from the University of York's Department of Psychology, and Dr Tuomas Eerola, from the Finnish Centre of Excellence in Interdisciplinary Music Research at the University of Jyvaskyla.

NEANDERTHAL GENES CHANGED US ALL

NEANDERTHALS SHARED THERE GENES WITH HUMANS AND IT CHANGED OUR LIVES Thousands years ago, Neanderthals lived with humans and they shared there brides.It caused mixing of Neanderthal genes with our genome.That cause lot of good as well as bad effects on Humans. Between 2% and 4% of the genetic blueprint of present-day non-Africans came from Neanderthals. Neanderthal genes have contributed to human immunity and modern diseases. They passed some genes that involving with type 2 Diabetes, Crhon's disease, long term depression,lupus, Billiary Cirrhosis and smoking addiction. Their gene affects our coagulation system as well.Some people, more prone to allergies, also have some genes of Neanderthals. They have also passed good genes also, the genes involving skin pigmentation gave better advantage to adapt Asians to high sun exposure,climate changes and some of pathogens living in the environment. Recently researchers found that Neanderthal genes contributed othe...
