Scientist’s endless efforts to conquer the problem of obesity are not new to the world. People are well-versed with the fact that researchers have been striving hard to eradicate the problem of obesity from its root. Their unstoppable thirst to look for a cure has made it possible to solve many unsolvable health complications. Likewise, a recent revelation of some factual information pertaining to obesity may help to address the doubt regarding effect of fatty foods on the cells of brain. Scientists undertook a research on mice. The research result advises that highly fatty foods initiate the production of some new brain cells which trigger weight gain in mice.
As per the opinion of experts like neuroscientist Seth Blackshaw of Johns Hopkins University School of Medicine and a published online report on March 25th in Nature Neuroscience, except few rare cases, most part of the human brain does not make any new nerve cells. But there is a place called the median eminence, which makes new nerve cells throughout the whole life of a human being and is also a vital place of brain’s metabolism. Read the full story

The DNA databases are well protected resources, as they have a large number of detailed fingerprints that may be employed to discover an individual from cancer, paternity tests, genetic predisposition up to criminal records. It also appears that RNA databases, a derivative of large genome studies are used in the identification of persons. The databases are available in journals and to the public, and have the information from large number of people worldwide.
Having these discoveries, the scientists can improve the health of a patient using the RNA and deep individual data. But this as well brings up some questions concerning the genomic privacy.
The study performed in New York at the Mount Sinai School Medical Department changes the RNA detection process inside out. Scientists Ke Hao and Eric E. Schadt discovered that to get the DNA of an individual by use of RNA data. Nearly all the studies revealed how the RNA relays the genetic information using DNA sequences. Read the full story

The human genome project was one among the most ambitious projects and a lot has been revealed from the results. A decade ago, a few scientists showed the world, the sequence of the entire human genome. Since the completion of this ardent project, scientists have been trying to unravel the genetic sequence of the apes- with whom we shared our ancestors some ten million years ago. After the successful completion of the gene sequence of the other apes like chimpanzee (which was published in the year 2005) and orangutan (published in 2011), gorillas now have their complete gene sequence analyzed.
The results reveal a close association between the human genome and that of the gorillas. The astonishing fact is that parts of the human genome share a higher degree of similarity with the genomes of the gorilla’s than that of the chimp’s. In fact, the gorillas share the same set of genes that highlight our unique evolutionary pattern. The genetic sequence analysed was that of a western lowland gorilla, a female, named Kamillah, who lives at the San Diego Zoo Safari Park. The DNA of other gorillas were also sequenced; that includes two more western lowland gorillas and one eastern lowland gorilla, which is a rare species. Read the full story
