Geneticists can determine your age using a saliva sample

-
You want to hide your age? If that's the case, you need watch carefully where you spit. Men of science from UCLA discovered a saliva test that will reveal your real age. This new discovery opens doors for a wide range of applications. A fresh patented test could help crime-scene investigators to discover suspect's real age without knowing anything else about them.



"Our approach supplies one answer to the enduring quest for reliable markers of aging," said principal investigator Dr. Eric Vilain, a professor of human genetics, pediatrics and urology at the David Geffen School of Medicine at UCLA.

"While genes partly shape how our body ages, environmental influences also can change our DNA as we age," Vilain said. "Methylation patterns shift as we grow older and contribute to aging-related disease."

Vilain and his squad picture the test turning a forensic creature in crime-scene investigations. By examining traces of spit left in a tooth bite or on a coffee cup, research lab experts may specify the age of a criminal suspect to a five-year range.


The findings can be found in June 22 PLoS One - an online journal of the PLS.

Mathematics model anticipates obscure biologic Mechanism Of Regulation

A squad of Researchers, conducted by a biomedical technologist have established that possible patterns produced from information received by desoxyribonucleic acid microarrays, could be expended to correctly anticipate antecedently unidentified cellular mechanisms. This gets biologists a footstep nearer to one day equaling able to empathize and command the inside works of the cell as promptly as NASA masterminds secret plan the flights of space vehicle nowadays. "Thanks to the Human Genome Project, biology and medicine today may be at a point similar to where physics was after the advent of the telescope," averred Orly Alter, adjunct professor of biomedical applied science In a 2004 report issued in the Proceedings of the National Academy of Sciences in coaction with Gene H. Golub of Stanford University, Alter applied numerical formulas inspired by those used in quantum mechanism to anticipate a antecedently unidentified mechanism of ordinance that correlates the commen

Horrors of Anorexia

Anorexia is an eating disorder where people starve themselves. Anorexia usually begins in young people around the onset of puberty. Individuals suffering from anorexia have extreme weight loss. Weight loss is usually 15% below the person's normal body weight. People suffering from anorexia are very skinny but are convinced that they are overweight. Weight loss is obtained by many ways. Some of the common techniques used are excessive exercise, intake of laxatives and not eating. Anorexics have an intense fear of becoming fat. Their dieting habits develop from this fear. Anorexia mainly affects adolescent girls. People with anorexia continue to think they are overweight even after they become extremely thin, are very ill or near death. Often they will develop strange eating habits such as refusing to eat in front of other people. Sometimes the individuals will prepare big meals for others while refusing to eat any of it. But anorexia can be cured

The Brown Recluse Spider is also called violin spider and after watching the following pictures I really understand I should avoid it. These spiders are around 6-20 mm but it may grow larger. You will find violin spiders in abandoned or disorderly shelters.  These picture were posted on Reddit by a user, saying that his friend was bitten by the Recluse Spider.  Apparently, the Recluse Spider bite looked just like an infection.
