The Biology Project New Antibiotic Stirs Hope Against Resistant Bacteria Photo An unusual method for producing antibiotics may help solve an urgent global problem: the rise in infections that resist treatment with commonly used drugs, and the lack of new to replace ones that no longer work. The method, which extracts drugs from bacteria that live in dirt, has yielded a powerful new antibiotic, researchers reported in the journal Nature on Wednesday. The new drug, teixobactin, was tested in mice and easily cured severe infections, with no side effects. Better still, the researchers said, the drug works in a way that makes it very unlikely that bacteria will become resistant to it. Teixobactin has not yet been tested in humans, so its safety and effectiveness are not known. Experts not involved with the research said the technique for isolating the drug had great potential. Dr. Regarding teixobactin, he said: “It’s at the test-tube and the mouse level, and mice are not men or women, and so moving beyond that is a large step, and many compounds have failed.” Dr.

Sources of Food Affect Dietary Adequacy of Inuit Women of Childbearing Age in Arctic Canada The Science Spot Reference Cards I have created reference cards for many of the units/activities listed below, which are designed to replace the student worksheets and some lab pages for those units. The cards are printed on card stock (back-to-back) and laminated for student use. Students use overhead markers to add notes to the pages as we discuss each lesson and keep them to review for the unit quizzes. (You could also have students record their answers in a lab notebook rather than write on the pages.) At the end of the unit, they clean them off with a wet cloth and turn them in so they are ready for the next class! Daily CSI Challenges I start each class period with a warm-up activity targeting forensic science concepts and other skills (observation, problem-solving, etc.) Forensic Science A to Z Challenge (PDF) - Students must use clues to identify forensic science terms and then find them in a "bent word" style word search.

EnergyDrinksLesson.pdf In Hopes Of Fixing Faulty Genes, One Scientist Starts With The Basics Jennifer Doudna and her colleagues found an enzyme in bacteria that makes it much easier to edit DNA in animal cells. Cailey Cotner/UC Berkeley hide caption itoggle caption Cailey Cotner/UC Berkeley Jennifer Doudna and her colleagues found an enzyme in bacteria that makes it much easier to edit DNA in animal cells. Cailey Cotner/UC Berkeley Whether they admit it or not, many (if not most) scientists secretly hope to get a call in October informing them they've won a Nobel Prize. But I've talked to a lot of Nobel laureates, and they are unanimous on one point: None of them pursued a research topic with the intention of winning the prize. That's certainly true for Jennifer Doudna. The idea came when she and her colleagues at the University of California, Berkeley, were in essence trying to figure out how bacteria fight the flu. It turns out bacteria don't like getting the flu any more than the rest of us do. As Doudna was studying a group of these enzymes, she realized something.
