Lyme disease is caused by the microbe Borrelia burgdorferi, which is transmitted to humans from feeding ticks. http://www.physorg.com/news177620366.html Biology Mon, 16 Nov 2009 21:30:01 EST news177620366 (PhysOrg.com) -- Biologists have shown that independent but similar molecular changes turned a harmless digestive enzyme into a toxin in two unrelated species -- a shrew and a lizard -- giving each a venomous bite. http://www.physorg.com/news176037445.html Biology Thu, 29 Oct 2009 12:18:32 EST news176037445 The carnivorous reptiles (Varanus komodoensis) are known to bite prey and release them, leaving them to bleed to death from their wounds: the victims are reported to go into shock before the dragons kill and eat them. http://www.physorg.com/news161885734.html Biology Mon, 18 May 2009 17:16:10 EST news161885734 Researchers at the Johns Hopkins Malaria Research Institute (JHMRI) have identified the molecular components that enable the malaria-causing parasite Plasmodium to infect the salivary glands of the Anopheles mosquito -a critical stage for spreading malaria to humans. According to the researchers, saglin, a mosquito salivary protein, is a receptor for the Plasmodium protein Thrombospondin-Related Anonymous Protein (TRAP). The two proteins bind together to allow invasion of the salivary gland by Plasmodium sporozoites, which can be transmitted to a human when bitten by an infected mosquito. The findings are published January 16 in the open-access journal PLoS Pathogens. http://www.physorg.com/news151309041.html Biology Fri, 16 Jan 2009 06:17:21 EST news151309041 A powerful antioxidant in green tea may prevent or delay the onset of type 1 diabetes, Medical College of Georgia researchers say. Researchers were testing EGCG, green tea's predominant antioxidant, in a laboratory mouse with type 1 diabetes and primary Sjogren's syndrome, which damages moisture-producing glands, causing dry mouth and eyes. http://www.physorg.com/news143983831.html Medicine & Health Thu, 23 Oct 2008 12:30:31 EST news143983831
