WHOI Scientists Analyze, Explain the Chemical Makeup of Gulf Plume

Taking another major step in sleuthing the 2010 Deepwater Horizon oil spill, a research team led by the Woods Hole Oceanographic Institution (WHOI) has determined what chemicals were contained in a deep, hydrocarbon-containing plume at least 22 miles long that WHOI scientists mapped and sampled last summer in the Gulf of Mexico, a residue of the Deepwater Horizon oil spill. Moreover, they have taken a big step in explaining why some chemicals, but not others, made their way into the plume.

The findings, published this week in the online edition of the Proceedings of the National Academy of Sciences, “help explain and shed light on the plume formation and verify much of what we thought about the plume’s composition,” said WHOI chemist Christopher Reddy, lead author of the study. The data “provide compelling evidence” that the oil component of the plume sampled in June 2010 essentially comprised benzene, toluene, ethybenzene, and total xylenes—together, called BTEX—at concentrations of about 70 micrograms per liter, the researchers reported.

Neurosurgeon’s Rare Skills Saved a Haitian Priest’s Life

Health

On April 26, Dr. Ketan Bulsara, using state-of-the-art technology, threaded a catheter less than one centimeter in width from the femoral artery in Norbert Tibeau’s thigh into an aneurysm in his brain. The aneurysm had grown to a diameter of two centimeters and bordered on such critical structures as the optic nerve and pituitary gland. If left untreated chances were high that within five years it would either kill Tibeau or devastate him neurologically. (more…)

Landscape Change Leads to Increased Insecticide Use in U.S. Midwest

Environment

*Growth of cropland, loss of natural habitat to blame*

The continued growth of cropland and loss of natural habitat have increasingly simplified agricultural landscapes in the Midwest.

In a study supported in part by the National Science Foundation’s (NSF) Kellogg Biological Station Long-Term Ecological Research (LTER) site in Michigan–one of 26 such NSF LTER sites around the world–scientists concluded that this simplification is associated with increased crop pest abundance and insecticide use.

Tai Chi Helps Prevent Falls and Improves Mental Health in Elderly

Health

Tai Chi helps reduce the risk of falls in the elderly, and improves mental health, is what a new study shows. However, practicing the ancient Chinese art does not help to ease the symptoms of cancer or rheumatoid arthritis.

The information is from the research of a team that analyzed 35 reviews of studies evaluating the effects of Tai Chi on health.

The databases reviewed were British, Chinese and Korean that assessed the impact of Tai Chi on various diseases, including diabetes, hypertension, cancer, osteoarthritis, Parkinson’s, musculoskeletal pain, rheumatoid arthritis, osteoporosis and cardiovascular disease. (more…)
