HIV Tamed By Designer ‘Leash’


This thin-section transmission electron micrograph (TEM) depicted the ultrastructural details of a number of human immunodeficiency virus (HIV) virus particles, or virions.

Researchers have shown how an antiviral protein produced by the immune system, dubbed tetherin, tames HIV and other viruses by literally putting them on a leash, to prevent their escape from infected cells. The insights, reported in the October 30th issue of the journal Cell, a Cell Press publication, allowed the research team to design a completely artificial protein — one that did not resemble native tetherin in its sequence at all — that could nonetheless put a similar stop to the virus.

One Shot Of Gene Therapy, And Children With Congenital Blindness Can Now See


Researchers from the University of Pennsylvania School of Medicine and the Center for Cellular and Molecular Therapeutics at the Children’s Hospital of Philadelphia have used gene therapy to safely improve vision in five children and seven adults with a rare form of congenital blindness

Born with a retinal disease that made him legally blind, and would eventually leave him totally sightless, the nine-year-old boy used to sit in the back of the classroom, relying on the large print on an electronic screen and assisted by teacher aides. Now, after a single injection of genes that produce light-sensitive pigments in the back of his eye, he sits in front with classmates and participates in class without extra help. In the playground, he joins his classmates in playing his first game of softball.

Stimulating Sight: Retinal Implant Could Help Restore Useful Level Of Vision To Certain Groups Of Blind People


scientists have developed a pair of glasses that receive visual data from a camera mounted on a them and send the images to a chip attatched on the side of the eyeball.

Inspired by the success of cochlear implants that can restore hearing to some deaf people, researchers at MIT are working on a retinal implant that could one day help blind people regain a useful level of vision.

Cancer In Humans: Cost Of Being Smarter Than Chimps?


A new study suggests that humans cognitively superior brains means
more instances of cancer compared to chimpanzees

Are the cognitively superior brains of humans, in part, responsible for our higher rates of cancer? That’s a question that has nagged at John McDonald, chair of Georgia Tech’s School of Biology and chief research scientist at the Ovarian Cancer Institute, for a while. Now, after an initial study, it seems that McDonald is on to something. The new study is available online in the journal Medical Hypothesis and will appear in the forthcoming issue of the journal.

Swine Flu Update


CDC developed PCR diagnostic test to detect novel H1N1 virus.

On June 11, 2009, the World Health Organization (WHO) raised the worldwide pandemic alert level to Phase 6 in response to the ongoing global spread of the novel influenza A (H1N1) virus, which causes swine flu. A Phase 6 designation indicates that a global pandemic is underway.

Common Cold Symptoms Caused By Immune System


                                                                                                                        The Word Adam ^^^^:)

A University of Calgary scientist confirms that it is how our immune system responds, not the rhinovirus itself, that causes cold symptoms. Of more than 100 different viruses that can cause the common cold, human rhinoviruses are the major cause.

Clock-shifts Affect Risk Of Heart Attack


 Get that extra hour of sleep! But dont have a heart attack!

Adjusting the clocks to summer time on the last Sunday in March increases the risk of myocardial infarction in the following week. In return, putting the clocks back in the autumn reduces the risk, albeit to a lesser extent. This according to a new Swedish study
