...SWEDISH SCIENTISTS A team from Uppsala University has reported the existence of bacteria that can manufacture minute quantities of silver. The discovery may lead to the production of new kinds of metal films and coatings...
...July the American Academy of Pediatrics and the U.S. Public Health Service urged vaccine makers to remove the trace of mercury preservative added to many vaccines to kill bacteria. While the amount of the additive, called thimerosal, in a single vaccine poses no threat, it's remotely possible that the accumulated mercury in multiple inoculations might cause neurological damage. "We took action before evidence of any harm," says Dr. Walter Orenstein, head of the national immunization program for the Centers for Disease Control. "But even with a theoretical risk, we wanted to work with manufacturers to get to thimerosal-free...
RESISTANCE REDUX It's happening again. The newest class of antibiotics, called fluoroquinolones, may be losing its punch. A huge study in Canada concludes that 5% of S. pneumoniae bacteria--a common bug responsible for pneumonia and meningitis--may be resistant to fluoroquinolones. Doctors had hoped that because fluoroquinolones, unlike previous antibiotics, are synthetic, bacteria wouldn't be able to outsmart them...
...from farms, kill the ecosystem by starving fish. These nutrient pollutants are found in fertilizer and in sewage, and they cause excessive growth of aquatic plants when they hit the water. Algae, during their natural course of life, die and sink to the bottom, where they are devoured by bacteria, which use oxygen. Too many algae deprive fish of oxygen...

Instead, take a pair of tweezers, line them up alongside the tick's body and as close to your skin as you can and gently pull out the tick. Be sure not to squeeze or crush the tick...
