POPSTop 5 brain health foods! period the coffee bean, much like the cacao bean, is incredibly rich with antioxidants, amino acids, vitamins and minerals. Fresh-ground gently roasted coffee bean powder (again, like with cacao) has numerous brain and body health benefits....so folks,now you may drink a MUG OF COFFEE! happily...

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

POPSWhy We Laugh And Cry I'm the type of person who can laugh and/or cry at just about anything. It makes me happy to do both. Sometimes people can say to me, "Oh, don't cry" but I most often feel and say "Oh don't worry, it's a good cry" and this article explains why it always apparently feels so good afterwards doing either. We have emotions and responses to them for a reason. Use them and we may just live longer, healthier and happier lives because of it! :)

POPSViruses can catch colds, says study that redefines life itself Prof La Scola and his colleagues were surprised to spot a smaller type of virus attached to the virus-making factory inside infected cells. The new virus - Sputnik - was unable to infect cells by itself but seemed to hijack the larger to achieve its infectious aims. By regulating the growth and death of plankton, giant viruses - and satellite viruses such as Sputnik - could be a major influence on ocean nutrient cycles and climate. "These viruses could be major players in global systems," Nature is told by Prof Curtis Suttle, an expert in marine viruses at the University of British Columbia in Vancouver.

POPSScientists Apply for First Patent on Synthetic Life Form Without getting into the ethical implications which are fundamental and complex, This is an unprecedented step, a far reaching dangerous idea rapidly reaching its timely fruition, full of both positive potential and peril. Welcome to the 21st century :-) We will really have to tread wisely and courageously here.

POPSA Game worthwhile playing ! As a serious gamer I am certainly going to devote some time to this one. The idea is brilliant. Collaborative computing may bring breakthroughs that are decades away otherwise. If you pop this at least give the game a try :-)

POPSWhat happens when you cry? " one study collected both reflex tears and emotional tears (after peeling an onion and watching a sad movie, respectively). When scientists analyzed the content of the tears, they found each type was very different. Reflex tears are generally found to be about 98 percent water, whereas several chemicals are commonly present in emotional tears First is a protein called prolactin, which is also known to control breast milk production. Adrenocorticotropic hormones are also common and indicate high stress levels. The other chemical found in emotional tears is leucine-enkephalin, an endorphin that reduces pain and works to improve mood. Of course".

POPSPossible 'Sleep Gene' Identified When closed, the channel shuts down and the fly sleeps. The insomniac fruit flies had less of the Sleepless-produced protein. The lack of sleep didn't come without consequences. The Sleepless fruit flies lived about half as long as fruit flies that did not carry the mutation. They also experience impaired coordination and restlessness in their few hours of sleep.

POPSSocial Interactions Can Alter Gene Expression In Brain, And Vice Versa A critical insight came in 1992, in a study of songbirds led by David Clayton. He and his colleagues found that expression of a specific gene increases in the forebrain of a zebra finch or canary just after it hears a new song from a male of the same species. This gene, egr1, codes for a protein that itself regulates the expression of other genes.

POPSScientists Find a Second Code Hidden in DNA How cool is this? A secondary DNA meta-code has been discovered superimposed on top of the same "genetic code" whose transcription it influences! (Douglas Hofstadter would have had a field day with this!) Highly efficient from an information science point of view. There are so many wonders to be discovered within our very selves!

POPS15-ish Things Worth Knowing About Coffee
“Black as the devil, hot as hell, pure as an angel, sweet as love.” That’s the recipe for coffee, according to the utterly French statesman Talleyrand (1754-1838). AFRICAN ORIGINS (Circa A.D. 800) Goats will eat anything. Just ask Kaldi the legendary Ethiopian (map) goatherd. Kaldi, the story goes, noticed his herd dancing from one coffee shrub to another, grazing on the cherry-red berries containing the beans. He copped a few himself and was soon frolicking with his flock. Witnessing Kaldi’s goatly gambol, a monk plucked berries for his brothers. That night they were uncannily alert to divine inspiration. History tells us other Africans of the same era fueled up on protein-rich coffee-and-animal-fat balls"primitive PowerBars"and unwound with wine made from coffee-berry pulp. Coffee later crossed the Red Sea to Arabia, where things really got cooking... ESCAPE FROM ARABIA (Circa 1000 to 1600) Coffee as we know it kicked off in Arabia, where roasted beans

This is a public service clip so you don't have to make a fool of yourself and post a comment telling the world how you believe Jesus told you evolution was ungodly.

POPSSelectively Deleting Memories "One thing that we're really intrigued by is that this is a selective erasure," Tsien says. "We know that erasure occurred very quickly, and was initiated by the recall itself." "But people are very interested in devising a way where you could come up with a drug to expedite a way to do that," he says. That kind of treatment could change a memory by scrambling things up just in the neurons that are active during the specific act of the specific recollection. "That would be a very powerful thing," Mayford says. But the puzzle is an incredibly complex one, and getting to that point will take a vast amount of additional research. "Human memory is so complicated, and we are just barely at the foot of the mountain," Tsien says.

POPS'Supermice' who can resist cancer and age almost half as fast as normal In the latest study, published in the journal Cell, the scientists solved that problem by changing the genes of the mice first to make them resistant to the disease. The researchers found that mice which had been created in this way had better muscle in old age, healthier skin tissue and fewer digestion problems. "By simultaneously increasing the amounts of telomerase and the resistance to cancer we are able to delay ageing in mice and also to extend their life span by 40 per cent," said Maria A. Blasco, from the Spanish National Cancer Research Centre (CNIO), who carried out the study with colleagues from Valencia University. "These mice get to live for as long as the eldest mice in records of the same kind. "If we were to parallel it to humans, then it would mean reaching 120 years of age and also to start ageing much later in life."
