Chemotherapy Drug Packs A One-two PunchCancer can be wily, and those who treat the disease have amassed a wide array of weapons with which to fight it and kill tumors. Radiation treatment and various forms of chemotherapy were all believed to be separate but equal therapys. Now, however, new research is beginning to show that it's not just killing the cancer cells that matter. How they're killed may turn out to be just as important and could play a role in marshalling the body's........Go to the Cancer-blog (Added on 2/20/2007 7:51:55 PM)

Those Who Once Were Blind Can Learn To SeeHow does the human brain "learn" to see? If the brain is deprived of visual input early in life, can it later learn to see at all?
MIT scientists are exploring those questions by studying some unique patients--people who were born blind, or blinded very young, and later had their sight restored.
Doctors have long believed that children who were blind during a "critical period" early in life had little hope of learning how to see even if........Go to the Ophthalmology news blog (Added on 2/19/2007 8:11:39 PM)
