...Although all three women started out around the same time, the orangutans remain the least studied of the four great apes (there are two distinct species of chimpanzee) that are humankind's closest relatives, sharing some 97% of our DNA. In part that's a matter of numbers?there are thousands of chimpanzees in zoos in the U.S. alone, whereas orangutans barely exceed 100. But there is also a practical problem: chimps and gorillas are both essentially ground-dwelling group animals. Orangutans are solitary and spend most of their time in the high canopy of the rain forest, making even...
...been looking for compounds that will rewire tumor cells so they will know when it's time to go. The research is still in its early stages, but scientists in several labs have started looking at a group of enzymes called caspaces; inhibiting these enzymes disrupts the process of DNA repair that occurs each time a cell divides...
Along the way, though, scientists have amassed a wealth of information about how cancer works at the molecular level, from its first awakening in the aberrant DNA of a single cell's nucleus to its rapacious, all-out assault on the body. Armed with that information, they have been developing a broad array of weapons to attack the disease every step along the way. Many of these therapies are just beginning to reach clinical trials and won't be available to save lives for years to come. If you have cancer today, these treatments are likely to come too late...
...chew openings in normal tissues and give themselves room to expand. And, most famously, the class of compounds known as angiogenesis inhibitors keep tumors from building new blood vessels to supply themselves with food and oxygen. Three years ago, Nobel laureate James Watson, co-discoverer of the structure of DNA, was quoted as saying Dr. Judah Folkman, the Harvard researcher, would use these inhibitors to "cure cancer within two years...
