New mutations in schizophrenia
New genetic errors have appeared more frequently in patients than their parents. The results may indicate that many cases of schizophrenia, new mutations arise spontaneously and are not the result of many inherited genes, working in concert. International Group of scientists decode genetic prior 14 sick and the parents of those persons. The team examined only for producing protein genes, which are a tiny fraction of genetic instructions, but found 15 new mutations in the eight people with schizophrenia. People with schizophrenia, develop new mutations in more than twice the height of the average, the researchers report online on July 10, in nature Genetics. — Tina Hesman Saey
Mice get human livers
The question of a mouse or a man just got a little fuzzy. The researchers, led by Sangeeta Bhatia MIT engineering artificial liver liver human cell on which the scaffold of the polymer, and then implanted liver packages under the skin or in the abdomens of the mouse. Mice with implants can break down drugs and protein product of the liver, just as humans do, the team reports online on July 11, in proceedings of National Academy of Sciences. Such "humanized" mice could be used to screen drugs and improve methods of treatment of diseases involving the liver. — Tina Hesman Saey
The Stroke Association be gone
Brains have a physical samonaprawiajaca of ingredients, which may help to prevent and redress from a blood clot caused by stroke. A piece of a protein called brain damage protects perlecan and helps cells, stimulation of the growth of new blood vessels, all without harmful side effects, an international group of researchers report online on July 11, in the journal of clinical investigation. Bit of a protein, called domain perlecan V restored the movement of the mouse and rat to prestroke levels when administered within 24 hours of the stroke. It is part of the brain's natural response of the stroke, the substance can be safely processed. — Tina Hesman Saey
The eye plays Newt
Shakespeare's witches can happy to learn that it is one of the Favorites of renewable resources of their components. Newts ' ability to regenerate the lens of the eye is not hampered by aging or repeated injury, an international team of scientists reports online 12 July as communications. Mammals, including humans, the loss of the possibility of renewal of the parts of the body to age but it seems that the newts don't have this problem. In the new study newts regrew lens 18 times in 16 years, without losing the quality of the lens. Learn how newts regenerate body parts can help improve human antiaging therapy. — Tina Hesman Saey
Potato genome
Po-tay-to, po-tah, however you pronounce, scientists are now calling the genome of the tubers (mainly) Done. Potatoes are 39,031 genes, an international group of scientists, known as the potato Genome Sequencing Consortium reports online on July 10, in nature. These genes are unique to 3,372 for potatoes. Analysis of the genetic potato liquid reveals that the plant made copies of his genetic instructions at least twice in the past. • Base of their resistance to disease and evolution of the bulbs may also be hidden between genes and the breeder may use the data to build better spuds. — Tina Hesman Saey
