Early on in the new fall course SCRB 180: “Repair and Regeneration in the Mammalian Brain,” Travis Roy came to the Biolabs to talk about hockey, his accident, and coping with the aftermath. As one of 250,000 Americans living with spinal cord injuries, Roy told the students that he could someday be treated by developments in the same field studied in the course...
SCRB 167: “What does Human Disease Teach us about Mammalian Biology?”—a 14-person seminar, takes a similar approach by bringing in patients suffering from the conditions covered in the class; one day featured a leukemia survivor and his wife, who discussed his past treatments, his bone marrow transplant, and his battle with “graft--versus-host” disease, in which transplant cells attack the cells of the host body...
What about people who seem to lack empathy altogether, like psychopaths? You talk about a "mammalian core." There's a book called Snakes in Suits, which is about psychopaths in business. Madoff would be a good example, probably, and Kenny Lay, the head of Enron. I find that such a striking title because it makes them into reptiles. Empathy is not a reptilian thing. Empathy is a mammalian thing. Psychopaths are capable of taking the perspective of somebody else, but only to take better advantage of you. They're able to play the empathy game, but without the feelings involved...
Scientists think rapamycin's cellular target - called mTOR for "mammalian target of rapamycin" - helps regulate the body's response to nutrients and may also, according to Strong, "gear up responses to stress," such as the oxidative stress that damages proteins and DNA and contributes to disease development. "What we're doing with rapamycin," Strong says, "is we're actually tricking the cells into thinking that they're depleted of nutrients. Rather than the animals losing weight - we haven't noticed any weight loss - they may be just using their proteins more efficiently, and then repairing proteins more efficiently...
...Maryland Mouse DNA Decoded In a breakthrough 10 years in the making, an international team of scientists has finished sequencing just the second complete mammalian genome: that of the mouse. The findings will help researchers better distinguish between mouse and human DNA--which are about 75% alike--and promote more targeted experiments on human illness...
