Surfer’s Simplified Theory of Everything
2007-11-15 23:17:00 An impoverished surfer has drawn up a new theory of the universe, seen by some as the Holy Grail of physics, which has received rave reviews from scientists. Garrett Lisi, 39, has a doctorate but no university affiliation and spends most of the year surfing in Hawaii, where he has also been a hiking guide and bridge builder (when he slept in a jungle yurt). In winter, he heads to the mountains near Lake Tahoe, Nevada, where he snowboards. “Being poor sucks,” Lisi says. “It’s hard to figure out the secrets of the universe when you’re trying to figure out where you and your girlfriend are going to sleep next month.” Despite this unusual career path, his proposal is remarkable because, by the arcane standards of particle physics, it does not require highly complex mathematics. Even better, it does not require more than one dimension of time and three of space, when some rival theories need ten or even more spatial dimensions and other bizarre concept...

Topic Arsenic for Sleeping Sickness
2007-11-12 03:36:00 Arsenic has a well-deserved reputation as a prisoner?s favorite weapon. Its toxicity also made it an attractive agent of warfare (as a gas called Lewisite) and pest control. Death in humans from arsenic results from inhibition of energy production. Arsenic targets the energy-producing organelle of the cell, the mitochondria, and disrupts oxidative phosphorylation.

Cosmic ?Bullets? Traced to Galactic Black Holes
2007-11-10 08:00:00 The most energetic particles in the universe likely come from enormous black holes nestled in the restless hearts of traumatized galaxies, scientists say. Where these cosmic “bullets” originated has been a source of much speculation, with scientists proposing everything from gamma ray bursts to decaying dark matter. But researchers using the Pierre Auger Observatory in Argentina ... More About: Black , Galactic , Bullets , Holes , Gala

Gravitation: Gravitational Fields
2007-11-09 07:52:00 A gravitational field is defined as a region in which a mass experiences a force. This force is known as the gravitational force. Placing a second mass in that field, will by definition, create a gravitational force on the second mass. Gravitational Force The gravitational force between two point masses is: Directly proportional to product of masses Inversely proportional to ... More About: Fields

2007-11-05 01:41:00 Sildenafil citrate, which has the brand name Viagra , was developed in the mid 1980s as a treatment for angina and hypertension. Early clinical trials showed that sildenafil failed to relieve angina, but many men reported improved erectile function. Given this unexpected finding, research switched to the use of sildenafil as a treatment for impotence. Now ... More About: Topic , Sildenafil
