controls production of tooth enamel

It may not be long when our grandparents can retain their big 'closeup' smiles even at advanced stages of their life as scientists have identified a gene that controls production of tooth enamel, promising replacement of teeth which can be grown on demand.The identification of the gene opens new vistas in the dental sciences as it could make possible repair of damaged enamel, a new concept in cavity prevention, restoration and even the production of replacement teeth.

The gene known as Ctip2 was known for several functions including immunity and development of skin and nervous system in the body. The researchers at Oregon State University in the US have found that this gene is also responsible for the development of tooth as well.
The findings were published in the latest edition of the journal 'Proceedings of the National Academy of Sciences' in America.One of the researchers Chrissa Kioussi said that it's not unusual for a gene to have multiple functions, but before this we didn't know what regulated the production of tooth enamel.
Scientists used mice whose Ctip2 gene was "silenced" as such animals come as an important tool for scientists to study what systems are present and what are missing.

Alfie Patten: A 13 year old father

Its seem to be impossible but it's TRUE.When you read this title you might think something different but the thing I am going to tell you it is quite true as well as shocking.Alfie Patten, 13, and his girlfriend Chantelle Steadman, 15 have baby. His daughter Maise Roxanne was born four days ago and weighed 7lb 3oz. I cannot understand how it can even be possible and even you would get the same question in you mind. When I saw the picture I feel like the oldest brother holding his youngest sister .boys this age I don't think has even ejaculate. but Physiologically, sperm can be produced and active at the age of eight to ten, If a kid can whack off and ejaculate, the sperm get active. Women carry the same eggs their entire lives, and it's even possible to get pregnant before menstruation starts but it is really unhealthy.it is not good for health.
I do feel sorry for him he is still a child and has no idea what has just happened first time you have sex and there you go - PREGNANT. Alfie, who is just 4ft tall, hasn't yet hit puberty and was 12 when the baby was conceived, said: "When my mum found out, I thought I was going to get in trouble. We wanted to have the baby but were worried about how people would react. "I didn't know what it would be like to be a dad. I will be good though, and care for it," he told The Sun newspaper. I think SEX education is what is needed, as children are having sex younger, schools and parents need to educate kids about sex earlier.

DNA of common cold mapped for first time

Scientists have deciphered the genetic code of common cold for the first time, a breakthrough which they claim could herald effective new treatments for the ubiquitous virus.There is no known cure for the virus, responsible for making millions cough and sneeze every year and which can also trigger asthma attacks. Now, an international team has mapped the DNA or "instruction manual" for 99 strains of the cold. As far as the study, the scientists have uncovered how the virus has evolved constructing a "family tree", and identified what they believe are vulnerabilities which could be targeted by new medications, the 'Science' journal reported.In fact, the study has shown for the first time that different strains can "swap genes" creating new strains of the virus, suggesting there would never be an effective vaccine. "Having sequenced the complete genomes of these things we now know you can be infected by more than one virus at a time and that they can recombine (their genes)," said Ann Palmenberg of Wisconsin-Madison University, who led the study."That's why we'll never have a vaccine for the common cold. Nature is very efficient at putting different kinds of paint on the viruses," 'The Daily Telegraph' quoted Palmenberg as saying.
