The Sterile Insect Technique (SIT), the release of sexually sterile male insects to wipe out a pest population, is one suggested solution to the problem of malaria in Africa. A new supplement, published in BioMed Central's open access Malaria Journal, reviews the history of the technique, and features details about aspects of its application in the elimination of malaria. http://www.physorg.com/news177593468.html Medicine & Health Mon, 16 Nov 2009 11:33:24 EST news177593468 The practice of sterilizing medical tools and devices helped revolutionize health care in the 19th century because it dramatically reduced infections associated with surgery. Through the years, numerous ways of sterilization techniques have been developed, but the old mainstay remains a 130-year-old device called an autoclave, which is something like a pressure steamer. The advantage of the autoclave is that the unsterile tools can be packed into sealed containers and then processed, staying sealed and sterile after they are removed. http://www.physorg.com/news176997452.html Physics Mon, 09 Nov 2009 15:30:11 EST news176997452 A theoretical physicist at the National Institute of Standards and Technology has developed a method for calculating the motions and forces of thousands of atoms simultaneously over a wider range of time scales than previously possible. The method overcomes a longstanding timing gap in modeling nanometer-scale materials and many other physical, chemical and biological systems at atomic and molecular levels. http://www.physorg.com/news176555152.html Physics Wed, 04 Nov 2009 11:09:16 EST news176555152 (PhysOrg.com) -- Seven open-ended questions could make children less suggestible during interviews. http://www.physorg.com/news175448862.html Medicine & Health Thu, 22 Oct 2009 17:40:04 EST news175448862 (PhysOrg.com) -- Women can significantly improve 'that time of the month,' by learning more about how premenstrual symptoms (PMS) can affect their minds and bodies and by adopting stress management and relaxation techniques. http://www.physorg.com/news175181529.html Medicine & Health Mon, 19 Oct 2009 15:10:07 EST news175181529 A screening test that measures whether a patient's heart is healthy enough for a kidney transplant is not as dangerous as once thought, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN).
