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

POPSTips from Thomas Edison on Living Optimistically Dr. Martin Seligman, the director of the University of Pennsylvania’s Positive Psychology Center, and author of Learned Optimism, has studied optimists and pessimists for 25 years. His research has found: Optimists * Less depression than pessimists * Better results than pessimists in most areas of life * Longer lifespan * Healthier than pessimists * Better than pessimists at work and in school * More friends and better social lives Pessimists * More depression than optimists * Inertia rather than activity in the face of setbacks * Feels bad subjectively–blue, down worried, anxious * Poor physical health * Self-fulfilling; pessimists don’t persist in the face of challenges and thus fail more frequently, even when success is attainable * Even when pessimists turn out to be right, they still feel worse than deluded optimists

POPSLanguage Without Numbers: Amazonian Tribe Has No Word To Express 'One,' Other Numbers However, the MIT team decided to add a new twist--they started with 10 objects and asked the tribe members to count down. In that experiment, the tribe members used the word previously thought to mean "two" when as many as five or six objects were present, and they used the word for "one" for any quantity between one and four. This indicates that "these aren't counting numbers at all," said Gibson. "They're signifying relative quantities." He said this type of counting strategy has never been observed before, although it may also be found in other languages believed to have "one," "two," and "many" counting words.

POPSMechanism Behind Mind-body Connection Discovered The study reveals how stress makes people more susceptible to illness. The findings also suggest a potential drug target for preventing damage to the immune systems of persons who are under long-term stress, such as caregivers to chronically ill family members, as well as astronauts, soldiers, air traffic controllers and people who drive long daily commutes.
