How To: Get rid of pesky winter moths

Winter moths (operophtera brumata) can be a nuisance to your trees during early spring time. The biggest concern is the larva, which is a caterpillar/inch-worm feed on the budding leaves of deciduous trees and you won't really notice it until your leaves are at their full size. A good way to get rid of the moths is with a bacterium called, BT (bacillus thuringiensis)or Spinosad a derivative of a bacterium. If you have really big trees, you may need to get an arborist to treat your trees.

News: This Genetic Defect Could Be Why Typhoid Mary Never Got Typhoid Fever

Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...

News: Bacteria Turned into Factories, Supplying Critical Enzymes to Make Cancer Drugs Cheaper & Save Endangered Yew Trees

Cytochrome P450 (P450s) are proteins found in nearly all living organisms, which play roles that range from producing essential compounds and hormones to metabolizing drugs and toxins. We use some of the compounds synthesized by P450 in plants as medical treatments, but the slow growth and limited supply of these plants have put the drugs' availability in jeopardy and jacked up prices.

News: New Study Says Stopping Slimy Biofilms Could Save Thousands a Year from Legionnaires' Disease

In the summer of 1976, 4,000 American Legionnaires descended upon the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania, for a four-day convention.

News: How Calcium Sets Off a C Diff Infection

Unfortunately, the very places we go to receive health care put us at risk for becoming infected with superbugs, bacteria exposed to so many antibiotics that they have become immune to their effects. Clostridium difficile (C. diff) is one such bacteria. It causes inflammation of the colon and rampant diarrhea that can have life-threatening consequences. Part of its virulence lies in the tough spores formed by the bacteria. They are responsible for starting infections in the colon and for spre...
