Heading off to school can mean bringing home a case of head lice. There are lots of over the counter products to fight those little critters. But a new study in the archives of disease in childhood finds that four out of five lice today have built a resistance to the stuff we buy over the counter that eighty-five percent don't blink and eye anymore when exposed to pyrethroid which is the main ingredient in over the counter lice fighters. So, if there's a lice problem on someone's head in your house, researchers say you may want to skip traditional remedies and go straight to your doctor for a prescription.
Cracking the Da Vinci Code was no small feat for Tom Hanks but researchers at Johns Hopkins University have topped that one. They've identified the genetic code for nearly 200 genes that mutate and lead to breast and colon cancer many of which were not previously known to play a role in these diseases. Experts say finding those new gene targets will allow new drugs to be developed much like the Blockbuster breast cancer drug Herceptin that targets certain genes. In order to find these genes experts had to look through the protein coding regions of thirteen thousand genes within cancerous tumors. Experts say this research lays the foundation for future research on colon and breast cancer however human applications are still years away.
