Growing Evidence Of Marijuana Smoke's Potential Dangers
In a finding that challenges the increasingly popular belief that smoking marijuana is less harmful to health than smoking tobacco, researchers in Canada are reporting that smoking marijuana, like smoking tobacco, has toxic effects on cells. Their study is scheduled for the Aug. 17 issue of ACS" Chemical Research in Toxicology, a monthly journal.

Tiller Murder Prompts Abortion Providers To Re-Evaluate Protective Measures, Security
The recent murder of Kansas abortion provider George Tiller has prompted other providers nationwide to reassess their need for protective measures against violent actions from opponents of abortion rights, the AP/San Francisco Chronicle reports. In the days following Tiller"s murder, many clinic officials nationwide said that they had contacted law enforcement and examined their existing security measures. U.S. Attorney General Eric Holder also ordered the U.S. Marshals Service to provide security to several clinicians and facilities. According to the AP/Chronicle, violence against abortion providers in the 1980s and 1990s forced many to take various precautionary measures in and around their clinics, while some underwent training to protect themselves.Kate Michelman, former president of NARAL Pro-Choice America, said the election of former President George W. Bush, an abortion-rights opponent, helped alleviate some violence against abortion providers. However, she said that she believes Tiller"s murder might indicate the situation is changing during the first months of President Obama"s administration. Obama has rejected abortion-rights opponents" calls for restrictions on the procedure and also reversed the "global gag rule," or "Mexico City" policy.Michelman said, "Historically, when those who oppose a woman"s right to decide are frustrated politically, they get more violent," adding, "I have been thinking about this ever since the [Obama] election." She said that some providers will remain fearful even though she believes clinics are now safe. "In the end ... if someone is out to get you and they are determined and have a chorus encouraging them, ... there"s not much you can do to stop them," Michelman said. Provider LeRoy Carhart, who provided abortion services at Tiller"s clinic, said that people who commit violence against abortion providers should be charged with hate crimes (Hanna, AP/San Francisco Chronicle, 6/3).

Schistosomiasis: Discovery To Aid In Future Treatments Of Third-World Parasites
Schistosomiasis, one of the most important of the neglected tropical diseases, is caused by infection with parasitic helminths of the genus Schistosoma. These parasites are long lived (>10 years) and dwell within blood vessels, where they produce eggs that become the focus of intense, chronic inflammatory responses. In severe cases, this inflammation is associated with life-threatening liver disease.

Using Satellites To Study Lyme Disease

Six University of Alabama at Birmingham (UAB) students and two students from other universities are using satellite imagery to identify possible habitats in Alabama for the black-legged tick that carries and transmits Lyme disease. The students are interns with the NASA-Marshall Space Flight Center DEVELOP Program. DEVELOP is a competitive internship in which students work with NASA and partner-agency scientists to carry out innovative research projects. The eight students are working in UAB"s Laboratory for Global Health Observation (LGHO) using data from the NASA Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensor on board the Terra satellite, as well as DigitalGlobe QuickBird satellite technology. The technology enables the team to identify the environmental factors in Alabama, specifically the Birmingham metro area, necessary for Lyme disease to occur, said UAB senior Nathan Renneboog, 21, the Marshall DEVELOP team leader. The interns work with an adviser, Senior Research Scientist Jeffrey C. Luvall with the NASA Marshall Space Flight Center. Along with the satellite remote sensing technology, the students are using geographic information systems (GIS) software to generate representations of Alabama in colorful, digital maps on their computer screens. The maps" color patterns detail conditions on the ground such as soil moisture and vegetation that support habitats for black-legged ticks, also known as deer ticks. Animals like the White-tailed deer and the White-footed mouse often are carriers of the ticks and the disease. Ticks carrying the disease often breed in heavily wooded areas. "There has been disagreement among health officials about the degree to which Lyme disease exists in Alabama," Renneboog said. By identifying these habitats, the students want to confirm that conditions are present in Alabama for the disease, he said. On Wednesday, July 29, team members will share their study results with local health officials to help raise public awareness of Lyme disease, Renneboog said. On Aug. 4, Renneboog will present the project results to senior executives at NASA headquarters in Washington, D.C. In addition to Renneboog, a native of Ghent, Belgium, the DEVELOP interns are UAB graduate students Lili Xie of Sichuan, China; Kathryn Roa of Davao, Philippines; Stephen Firsing III of Princeton, N.J.; Shveta Setia of Chandigarh, India; and Ret. Lt. Col. Marilyn McAllister of Athens. The team also includes Boston University student Emily Capilouto of Birmingham and LSU student Kyle Levy of Zachary, La. What is Lyme Disease? Lyme disease is caused by bacteria called Borrelia burgdorferi. Ticks can transmit the bacteria to people and animals when they bite skin. Symptoms often include a circular skin rash that appears three to 30 days after the tick bite, fever, chills, fatigue, muscle and joint aches and swollen lymph nodes. If left untreated, the disease can spread to other parts of the body. If diagnosed early, however, Lyme disease can be treated with antibiotics, experts say. About the UAB Laboratory for Global Health Observation The UAB Laboratory for Global Health Observation (LGHO) is the first satellite remote sensing laboratory in North America with a primary focus on medical and health-based research. Through the LGHO, UAB researchers use satellite imagery for anthropological and archaeological research and to track the spread of diseases on the earth and identify areas in which health disparities are occurring. The LGHO also offers courses in satellite remote sensing. About the NASA DEVELOP Program DEVELOP is an applied sciences training and development program that engages students to extend NASA science research and results to scientific and public communities. NASA and partner science advisers assist students in conducting scientific research projects and demonstrating outcomes to community leaders. Projects use NASA science research results, measurements and predictions and address the Applied Sciences National Applications. Professional-caliber products are delivered that can assist community decision-making, and students gain the capability to contribute immediately to the science community.
