What Is Malaria?
The word malaria comes from 18th century Italian mala meaning "bad" and aria meaning "air". Most likely, the term was first used by Dr. Francisco Torti, Italy, when people thought the disease was caused by foul air in marshy areas. It was not until 1880 that scientists discovered that malaria was a parasitic disease which is transmitted by the anopheles mosquito. The mosquito infects the host with a one-cell parasite called plasmodium. Not long after they found out that Malaria is transmitted from human-to-human through the bite of the female mosquito, which needs blood for her eggs.

President Obama Needs To Rethink His Call To Defund Current Abstinence Education Programs - National Abstinence Education Association
NAEA calls upon Congress to reject the President"s request to eliminate abstinence education funding from the 2010 budget. NAEA also urges the Administration to retract its overreaching decision to zero out abstinence education funding. Abstinence education programs must continue using the same legislative guidelines as have been applied under the previous administrations of Clinton and Bush.

Which Country Ranks Highest In Biotech Innovation
In a first of its kind study, Scientific American cut through the marketing messages to take a hard look at what countries across the globe are doing to bolster biotech programs within their borders. Many rankings compare Europe, Asia, and the US -- the Scientific American Worldview: A Global Biotechnology Perspective digs deeper, examining all the elements that impact overall biotech innovation. You might be surprised by some of the results.

Less Than One Drop Of Blood Needed By New Device To Detect Heart Disease

Testing people for heart disease might be just a finger prick away thanks to a new credit card-sized device created by a team of researchers from Harvard and Northeastern universities in Boston. In a research report published online in The FASEB Journal, they describe how this device can measure and collect a type of cells needed to build vascular tissue, called endothelial progenitor cells, using only 200 microliters of blood. The development is also significant because it allows scientists to collect these cells much more easily than current techniques allow, bringing laboratory-created tissue for vascular bypass surgeries another step closer to reality. "This simple device is a promising tool for the pediatric and adult population in detecting, diagnosing, monitoring, and providing the option of treating cardiovascular disease by utilizing a small quantity of blood," said lead researcher Shashi K. Murthy of the Department of Chemical Engineering at Northeastern University in Boston. To collect the cells, the device works similar to Velcro™ or a magnet. Specifically, the inside is coated with antibodies that only bind to endothelial progenitor cells. Blood flows through the device through a funnel-like opening (except the blood enters through the narrow end and exits through the wide end), passes over the antibodies, and endothelial progenitor cells are "picked up" in the process. In addition to allowing researchers to collect cells from a very small amount of blood, the device"s design also provides researchers with a new model to study the effects that blood flow in the body has on cell binding (like clots form in arteries). "Most immediately, this is could be a new tool to assess cardiovascular health that cuts the amount of blood needed down to a pin prick. Its compact size might make it an excellent tool for use in developing countries where access to medical laboratories does not exist," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "In addition, this moves much closer to a future where new blood vessels, veins and arteries for transplants no longer need to be grafted from patient"s bodies. The amount of pain and recovery times for bypass surgeries would be reduced significantly." Cody Mooneyhan Federation of American Societies for Experimental Biology
