POPSAchilles Heel Of HIV Found?
“Unlike the changeable regions of its envelope, HIV needs at least one region that must remain constant to attach to cells. If this region changes, HIV cannot infect cells. Equally important, HIV does not want this constant region to provoke the body’s defense system. So, HIV uses the same constant cellular attachment site to silence B lymphocytes - the antibody producing cells. The result is that the body is fooled into making abundant antibodies to the changeable regions of HIV but not to its cellular attachment site. Immunologists call such regions superantigens. HIV’s cleverness is unmatched. No other virus uses this trick to evade the body’s defenses.” Paul’s group has engineered antibodies with enzymatic activity, also known as abzymes, which can attack the Achilles heel of the virus in a precise way. “The abzymes recognize essentially all of the diverse HIV forms found across the world. This solves the problem of HIV changeability. The next step is to confirm our theory in huma

POPSPolygamy is the key to a long life Men, by contrast, can reproduce well into their 60s and even 70s and 80s, and most researchers assumed this explained their longevity. But Lummaa and colleague Andy Russell wondered whether other factors explained the long lifespan of men, such as a grandfather effect. If female survival is the main explanation for male longevity, then monogamous and polygamous men would live for about the same length of time. Instead, it seems that fathering more kids with more wives leads to increased male longevity. Men, then, live long because they're fertile well into their grey years. The explanation could be both social and genetic. Men who continue fathering kids into their 60s and 70s could take better care for their bodies because they have mouths to feed. But evolutionary forces acting over thousands of years could also select for longer-lived men in polygamous cultures.

POPSBush gagged Surgeon General. Health, sex, smoking, cells, religion, Under Bush, the independence of the surgeon general has been placed below industry lobbying and the demands of the religious right. The Bush White House banned Dr Carmona from speaking or issuing reports on stem cells, emergency contraception, sex education, prisons, mental health and international health issues, he has revealed. For years, the White House also tried to "water down" a key report on the dangers of second-hand smoke, he said. When it was published last year , the report stated that even brief exposure to cigarette smoke can cause immediate harm.

POPSVery Sobering Images of the World Today Do not look at these if you are upset real easily, because they are awful, but they are real of what's going on round the world today. Still absolutely shocking though, it should't be going on anymore! Their is enough money in the world to stop this!

POPSThe blog post that wouldn't die I want to talk about atheists and anger. This has been a hard piece to write, and it may be a hard one to read. I'm not going to be as polite and good-tempered as I usually am in this blog; this piece is about anger, and for once I'm going to fucking well let myself be angry. But I think it's important. One of the most common criticisms lobbed at the newly-vocal atheist community is, "Why do you have to be so angry?" So I want to talk about: 1. Why atheists are angry; 2. Why our anger is valid, valuable, and necessary; And 3. Why it's completely fucked-up to try to take our anger away from us. So let's start with why we're angry. Or rather -- because this is my blog and I don't presume to speak for all atheists -- why I'm angry.<< http://gretachristina.typepad.com/

POPSThe 'morning after' HIV drug cocktail To my surprise I found that most people I know are not aware to the existence of such a life saving option. The treatment has some severe side effects but also a very high (81%) success rate. Keep this option in mind and inform your friends.

POPSAre we about to eliminate AIDS? Yet the idea of eliminating HIV is so appealing, and the benefit to humanity so huge, that scientists and policy-makers are seriously considering the concept, albeit on regional scales. In the next few months the World Health Organization (WHO) will meet to discuss how the idea could be tried in developing countries, and something approaching elimination might be attempted in the UK within the next decade. "You could eliminate transmission overnight," says Marcus Conant, an HIV specialist in San Francisco. Read on the interesting article.

POPSWho Is The Real Patriot? I may not agree with his religion or some of his views, but I'd rather be in his fox-hole than Dick Cheney's or George Bush's.

POPSIndigenous SEX Wipeout Deliberate? Survival International Survival's director Stephen Corry stated, "Tribal people die because their land is invaded and taken and because they succumb to outside diseases they never knew before. Increasingly now we can add HIV/AIDS to the list of killers. "It is striking the most vulnerable peoples of all: those who have no grasp of the risks of unprotected sex; no access to condoms; no appropriate treatment; and whose numbers are already small. The first solution is the simplest - governments must ensure tribal lands are properly protected."

POPSA long,melancholy roar Of our ancient enemies, microbes are now the most fearsome.HIV/AIDS chalked up 2 million deaths across the planet in 2007 alone; tuberculosis was close behind, with more than 1,700,000.The year before, malaria escorted almost a million people to their graves. We should be far more scared of mosquitoes than we are of bears; but we’re not. More recently, however, it’s been the case that the mammal most likely to kill a human is: a human. Murder and war have long been more important causes of death for us than predatory wild animals. But here’s the thing. Today, in many parts of the world, the human being most likely to cause your violent death is: you. Yes. You are the person most likely to kill yourself violently and on purpose. Suicide rates have risen dramatically over the past 50 years.

POPSScientists Develop New Computational Method To Investigate Origin Of Life "Retroelements are an ancient and highly diverse class of proteins; therefore, they provide a rigorous benchmark for us to test our approach. We are happy with the results we derived, even though our method is in an early stage," said Patterson. The team plans to make the algorithms that they used in their method available to others as open-source software that is freely available on the Web. Scientists map out the evolutionary histories of organisms by comparing their genetic and/or protein sequences. Those organisms that are closely related and share a recent common ancestor have greater degrees of similarity among their sequences.
