Deployment could lead transformation of toxic HAB monitoring

A new robotic sensor deployed by Woods Hole Oceanographic Institution (WHOI) in Gulf of Maine coastal waters may transform the way red tides or harmful algal blooms (HABs) are monitored and managed in New England. The instrument was launched at the end of last month, and a second such system will be deployed later this spring.

The results will add critical data to weekly real-time forecasts of New England red tide this year distributed to more than 150 coastal resource and fisheries managers in six states as well as federal agencies such as NOAA, the FDA and the EPA. Researchers also plan to add data from the sensor to regular updates provided on the “Current Status” page of the Northeast PSP website. (more…)

UCLA study challenges World Health Organization’s approach

The World Health Organization is about to roll out a new strategy for AIDS prevention in South Africa, a country where more than 5 million people are infected with HIV. Based on a mathematical model, the WHO predicts this strategy will completely eliminate HIV in South Africa within a decade.

But not so fast, suggests a group of UCLA researchers. Their work challenges the proposed strategy by showing it could lead to several million individuals developing drug-resistant strains of HIV. And further, they say, it will cost billions of dollars more than the WHO has estimated. (more…)

COLUMBUS, Ohio – Scientists have designed a screening tool that provides a fast, easy and relatively inexpensive way to predict levels of a specific toxin in lakes that are prone to blue-green algal blooms.

Blue-green algae is not your average pond scum – rather than consisting of plant-like organisms, blue-green algae actually are cyanobacteria, and some species are linked to the production and release of the toxin microcystin into the water. Human exposure to the toxin through drinking or recreational water contact can threaten public health by causing liver damage, neurological problems and gastrointestinal illness in humans. (more…)

Obesity Has Doubled Since 1980, Major Global Analysis of Risk Factors Reveals

*Study shows western high-income countries have achieved impressive progress in lowering hypertension and cholesterol*

The worldwide prevalence of obesity has nearly doubled since 1980, according to a major study on how three important heart disease risk factors have changed across the world over the last three decades. The study, published on Feb. 4 in three papers in the Lancet, looked at all available global data to assess how body mass index, blood pressure and cholesterol changed between 1980 and 2008.

The study shows that in 2008, more than one in ten of the world’s adult population was obese, with women more likely to be obese than men. An estimated 205 million men and 297 million adult women were obese – a total of more than half a billion adults worldwide. (more…)

Chernobyl Effects Could Last for Centuries

Nearly 25 years after the worst nuclear accident in history, new scientific findings suggest that the effects of the explosion at Chernobyl have been underestimated. Experts last month published a series of studies indicating that, contrary to previous findings, populations of animals decreased in the exclusion zone surrounding the site of the former nuclear power plant, and that the effects of radioactive contamination after the outbreak had been “overwhelming.”

Since Adam and Eve, snakes have long been portrayed as evil creatures to be feared. Aboriginal groups in Australia hold the snake in high esteem, and it is a symbol of fertility. Native Americans in North America felt that snakes symbolized life cycles and truth.
