Scientists unsure if humans are to blame for Hurricane Sandy – Following the devastation of Hurricane Sandy last week, one must ask “Did this storm occur as a result of global climate change?” While most climate scientists will not conclusively say that the storm resulted from global climate change, some will offer several pieces of evidence that global warming at least intensified the effects of the storm.

Politics and fetal diagnostics collide – A new diagnostic called non-invasive prenatal testing (NIPT) will increase the amount of genetic information available early in pregnancy. This test is currently used to determine a fetus’s blood type, gender, father, trisomy 21 (Down Syndrome) and trisomy 13. Due to its non-invasive nature and the fact that it can be completed at 10 weeks gestation rather than during the second trimester (when amniocentesis can be performed), NIPT is a valuable tool for diagnosing genetic abnormalities. This new screening method is strongly opposed by pro-life groups and has resulted in the introduction of new legislation to limit abortions following genetic screening. To date, “the FDA has not developed a regulatory scheme for genetic tests”. (Jaime King, subscription required)
Will Elephant Contraception Work in South Africa? – Although the elephant population in much of Africa is endangered due to poaching, the number of elephants in South Africa keeps increasing. Elephants eat approximately 600 pounds of food per day and can be incredibly destructive to their environment. Therefore, wildlife conservationists have encouraged the use of a contraceptive vaccine on female elephants to reduce elephant fertility. However, some experts oppose this new treatment and raise questions about its feasibility. (Martin Plaut)
