[Following a violent robbery, Joël] Coutu’s ordeal was just beginning. For years he would be tormented by violent nightmares, panic attacks brought on by the mere hint of aggression around him, and severe depression—signs of post-traumatic stress disorder (PTSD).
There is one thing we know for sure about antioxidants. They sell products. Unfortunately that is just about the only thing we know for sure about this fascinating class of chemicals.
In line with the recommendations of the Jutras Report, we’re working hard to improve every our emergency communications planning. To help, on Jan. 31 we’ll launch new software called Alertus that allows us to send pop-up announcements to your computer if an urgent situation arises. People using laptops, Macs or non-ICS-supported desktops will need to install this software manually.
Bacteria that evolve resistance to antimicrobial therapies may be able to evade natural immune peptides. However, bacteria can evolve resistance to AMPs under strong selective pressure in vitro.
Stanford Daily, Mercury News, Wall Street Journal - Stanford study shows women report more intense pain than men
The long-held notion that women have a higher tolerance for pain than men do has been upended by a Stanford University study released on Monday, January 23rd 2012.
As a supramolecular chemist, Hanadi Sleiman found herself strongly drawn to manmade DNA structures. 'We think of DNA as the most programmable structure there is. I thought - if it is - let me try to incorporate it into regular supramolecular structures,' says the professor at McGill University, Montreal, Canada.
Human emissions of carbon dioxide will defer the next Ice Age, say scientists. The last Ice Age ended about 11,500 years ago, and when the next one should begin has not been entirely clear.
(Chemistry professor Joe Schwarcz): A child born into a wealthy family is said to have "been born with a silver spoon in his mouth." The silver represents wealth, but thanks to the "oligodynamic effect," it may even have a connection to health.
Researchers have discovered they can induce supersoldiers in Pheidole ant species that never had them before. These supersoldier anomalies represent dormant ancestral potential that can be invoked by changes in the environment. These findings are groundbreaking for evolutionary theory, because they show there is dormant genetic potential that can be locked in place for a very long time.
In 2006, while collecting ants on an abandoned property in central Long Island, biologist Ehab Abouheif of McGill University noticed eight unusually oversized ants. They were anomalies to the region, but looked similar to the so-called "supersoldier" ants found in the American Southwest.
