Strong Link Found Between Concussions And Brain Tissue Injury
Concussions, whether from an accident, sporting event, or combat, can lead to permanent loss of higher level mental processes. Scientists have debated for centuries whether concussions involve structural damage to brain tissue or whether physiological changes that merely impair the way brain cells function, explain this loss. Now, for the first time, researchers have linked areas of brain injury to specific altered mental processes caused by concussions. Neuronal Conduction Of Excitation Without Action Potentials Based On C
Scientists are reporting the first discovery of conduction of excitation without action potentials. This opens up new perspectives for research by breaking away from the classic concept of neuronal functioning. This new mechanism involves molecules known to play a role in numerous mechanisms of cell functioning, but not hitherto in conduction of excitation. Environmental Literacy Council: Chlorine
"Chlorine is a greenish yellow diatomic gas with a noxious odor, poisonous to humans if inhaled even in small quantities. Chlorine was used as a poison gas in the trenches of Europe during World War I."This site provides information about this chemical's properties and applications. Also includes a link to information about salt (sodium chloride) and links to related sites. Cleaning With Catalysts
On repeated occasions we have read that volatile organic compounds are danaging for the atmosphere and to our health. This is why a group of researchers at the Leioa campus of the University of the Basque Country have put forward a process for "cleaning"these compounds before they are emitted into the atmosphere. Industry was chosen, amongst all the sources of these compounds, as the object for study. More than half of cheerleading injuries in US due to stunts
Whether rallying the crowd at a sporting event or participating in competition, cheerleading can be both fun and physically demanding. Although integral to cheerleading routines, performing stunts can lead to injury. Stunt-related injuries accounted for more than half (60 percent) of US cheerleading injuries from June 2006 through June 2007, according to a new study. Nearly all of the reported concussions occurred when the cheerleader was performing a stunt. Leptin Linked With More Aggressive Thyroid Cancer In Middle Eastern Re
Leptin, a molecule linked with obesity, may play a crucial role in predicting poor prognosis from thyroid cancer, at least in the Middle Eastern region of the world, according to new research. [Ironic] An Italian pensioner committed suicide after his wife fell in
Recalling the end of Romeo and Juliet, the 70-year-old man, Ettore, who had sat by his wife's bedside for four months after she slipped into a coma following a heart attack, finally gave up hope and gassed himself in the garage of his family home.Less than a day later, his wife, Rossana, woke up in her hospital bed in Padua and immediately asked for him. National Farm Toy Museum
Website for this Iowa museum that houses "thousands of toys and exhibits. ... of [t]ractors, implements, trucks, miniature farm dioramas, toy manufacturing information, and pedal tractors."Its site features photos of dozens of toy tractors from the museum's collectors tractor series, a "Kids Corner"with a tractor-part identification guide, and links to related sites. New Device Could Benefit Treatment Of Hand Injuries
Bioengineering students invented a device to measure intrinsic hand muscle strength. The device could revolutionize the diagnosis and treatment of hand injuries and neurological disorders, specifically carpal tunnel syndrome. Trees, Vines And Nets -- Microbial Evolution Changes Its Face
EBI researchers have changed our view of 4 billion years of microbial evolution. Christos Ouzounis and colleagues have gained intriguing quantitative insights into how gene families are transferred, not only 'vertically' through passage from one organism to its progeny, but also 'horizontally' through the exchange of genetic material between distantly related organisms. This new view of the tree of life could help us to better understand how disease-causing bacteria manage to stay one step ahead of us in our battle to tackle antibiotic resistance.
