...Professor Marshall’s accent on the ears. Overall: 3 Relevance to Life: 0 PowerPoint Presentations: N/A (Professor Marshall has gone back to prehistoric times himself and relies solely on the use of overheads) CHEMISTRY 30: ORGANIC CHEMISTRY Course Description: Topics include: Carbonyls, pericyclic reactions, stereochemistry, stereoelectric theory, molecular orbital theory, organometallic chemistry, rotovapping, Sn2 reactions, enolation, bromination, Grignard reactions, and pi orbital conjugation, to name a few. WTF?! Students are expected to come out of this course with total comprehension of all theories of organic chemistry. In reality, most obtain just enough knowledge to scrape...
...drug Relenza - one of only two drugs known to be effective against avian flu - Varghese is now focusing on an enigmatic protein, amyloid beta, and what he suspects are its toxic effects on the brains of people with Alzheimer's. In the international race to uncover amyloid beta's molecular structure - the crucial first step in finding out how to block its pathological effects - synchrotron X rays are a crucial tool. The molecules are too small to be imaged individually, so Varghese must grow them into crystals, each just 1/10,000th the width of a human hair, which are then...
...negotiations were handled by Bakang "B.K." Bala, a molecular biologist and sometime safari guide who is acting as cultural advisor to Minghella. According to the traditional Botswana khotla system, he made a presentation to the village chiefs, then withdrew, for several weeks, while the chiefs chewed over the matter with their constituents. "They didn't think we were serious at first," he says. "They were asking 'Why would you film a funeral? What sort of film are you making?' Some older people were saying it was bad luck, that if we filmed a funeral, then the village would certainly experience...
When treating cancer with surgery, it's crucial that every bit of the disease has been removed; but spotting cancer cells left behind after a tumor has been removed is difficult. Now, however, researchers at Seattle's Fred Hutchinson Cancer Research Center have created a molecular "paint" that coats cancer cells so doctors can see the wayward ones that they might otherwise miss...
That's especially exciting because painting tumors could also help doctors control cancers before they spread from an organ to the lymph nodes and other tissues. Olson's molecular paint can pick up tumors as small as 200 cells, potentially helping doctors identify, for instance, the micrometastases that can make breast cancer so dangerous. Current techniques like magnetic resonance imaging start detecting tumors at 1 million cells. "It's a way to extend what we can see," says Olson, making all our tools against cancer more powerful...
