the Human brain is still evolving

the Human brain is still evolvingThe quite modern for biological standards of the people who lived around 4000 BC, the brain continued to evolve, developing, say geneticists. And, probably, this is happening now. The consequences of "mutation" is not yet clear. But some experts say that in the past this led to landmark changes: exactly, in their opinion, the writing appeared and the city. Experts at the University of Chicago, headed by geneticist Bruce LAN examined two genes that regulate the growth of nerve cells in the brain. It was found that they significantly influenced the contents of the skull and after modern man has formed in biological terms about 200 thousand years ago. Читать полностью -->

Found a new way of struggle with addiction

Found a new way of struggle with addictionPharmacologists from the University of Wisconsin-Madison, has proposed a new method of dealing with drug addiction. We developed a special drug that kills euphoria arising from drugs. To achieve such a result in the body of the addict are injected antibodies that are associated with the drug, trying to counteract its effect. Previously it was not possible to deliver antibodies to the brain, so that the effect of this method was limited. The new method uses a virus that delivers antibodies in the brain. "The virus itself is safe, because all harmful sequence of genes in him removed, and the genes necessary antibodies Vice versa inserted into the genome," says study leader Arnold Ruoho.

In California started the program on stem cell research

In California started the program on stem cell researchThe research program in the field of stem cells was officially launched on Friday in California. The budget of the research is estimated at three billion dollars. The program will be headed by Robert Klein, a prominent businessman, who became one of the initiators of the commencement of the research. Scientists believe that stem cells from embryos can be used to treat disorders resulting from Parkinson's disease and Alzheimer's disease. In the November election studies in the field of stem cells was supported by 59 percent of voters. As you know, President Bush was opposed to the expansion of research in this area from the ethical considerations of the plan. Читать полностью -->

Endometriosis

EndometriosisENDOMETRIOSIS - heterotopia endometrium in organs and tissues where it is normally absent. Implant Theory of endometriosis is the leading; otorgada areas of the endometrium implanted in other tissues and organs; it is possible to transfer hematogenous route. Endometrioid inclusions can be observed in the thickness of the uterus (adenomyosis), in the lumen of the fallopian tubes on the pelvic peritoneum with growth in underlying tissues (rectovaginal partition), vagina, cervix, ovary with cyst formation ("chocolate" cysts, scar after cesarean section, rarely in areas remote from the uterine organs and tissues. Often, endometriosis is accompanied perifocal inflammation. Distribution and development of endometriosis is closely connected with the function of the ovaries. When natural or artificial menopause foci of endometriosis are subjected to reverse development. Читать полностью -->

Living tissue can be printed on an inkjet printer

Living tissue can be printed on an inkjet printerLiving tissue can be printed on an inkjet printer In practice, this ability was demonstrated by Vladimir Mironov, working at the Medical University of South Carolina and Thomas bouland of Crimsonscale University in the same state. Scientists were able to create using an inkjet printer, a three-dimensional cellular structures, in particular, of the tube. For the conduct of its work, the researchers used a conventional inkjet printer (brand not reported) and modified cartridges, in which were placed the cell solution. First of cartridges were thoroughly washed ordinary ink, then changed the scheme of charging and firmware controlling the operation of the cartridges were modified to reflect the properties of the new "biological ink". Print fabrics was carried out on glass plates coated with a layer of non-toxic, thermally reversible gel which hardens at temperatures above 32В°C and turns into a liquid when the temperature is below 20В°C. the Gel served as a binder for the cells, which has managed to create three-dimensional structures.
