The mountain goat is one animal perfectly adapted for life in alpine regions (areas above the tree line). Its teeth can chew the toughest vegetation, and its hooves have hard, sharp edges with a non-slip pad in the middle so they can climb on the steepest of ridges.
Stopping a killer
Stopping a killer New drugs are being developed for the treatment of
pancreatic cancer, one of the deadliest forms of cancer. Several
new types of therapies are being developed, including
chemotherapies, experimental vaccines, and drugs that interfere
with the genetic machinery of pancreatic cancer cells. The most
promising new chemotherapy drug is called "9-nitrocamptothecin", or
"9-nc". "9-nc" was developed from a compound called "camptothecin",
which is found in the Chinese tree, "camptotheca acuminata". It
disrupts cell replication and is currently in advanced human
trials. Drugs which target specific genes involved in forming
tumors are also being developed. 8 FEBRUARY 1999
