Combined research efforts by scientists involved in the Gulf of Maine Toxicity (GOMTOX) project, funded by NOAA’s Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, and administered by the National Centers for Coastal Ocean Science (NCCOS), have led to enhanced understanding of toxic algal blooms on Georges Bank. This new information, coupled with an at-sea and dockside testing protocol developed through collaboration between GOMTOX and U.S. Food and Drug Administration (FDA) investigators, has allowed fishermen to harvest ocean quahogs and surf clams in these offshore waters for the first time in more than two decades.

The shellfish industry estimates the Georges Bank fishery can produce up to 1 million bushels of surf clams and ocean quahogs a year, valued $10 – 15 million annually. “There is a billion dollars’ worth of shellfish product on Georges Bank that is property of the United States but that can’t be harvested because of the threat of toxicity, and 99.9% of the time, it is good wholesome product,” says Dave Wallace of North Atlantic Clam Association and a GOMTOX participant. “In an unusual and unique partnership, we worked with GOMTOX scientists, the FDA, and the states of Massachusetts, Rhode Island, New Jersey and Delaware and now that huge resource can go into commerce, which helps the entire country.” (more…)

Hidden Dangers in the Air We Breathe

Berkeley Lab researchers work on new building standards after discovering previously unknown indoor air pollutants.

For decades, no one worried much about the air quality inside people’s homes unless there was secondhand smoke or radon present. Then scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) made the discovery that the aggregate health consequences of poor indoor air quality are as significant as those from all traffic accidents or infectious diseases in the United States. One major source of indoor pollutants in the home is cooking.

The Berkeley Lab scientists are now working on turning those research findings into science-based solutions, including better standards for residential buildings and easier ways to test for the hazardous pollutants. These efforts are the result of a paper published in Environmental Health Perspectives in 2012 that described a new method for estimating the chronic health impact of indoor air pollutants. That research uncovered two pollutants that previously had not been recognized as a cause for concern—fine particles and a gas called acrolein. (more…)

Sweet Success: Berkeley Lab Researchers Find Way to Catalyze More Sugars from Biomass

Catalysis may initiate almost all modern industrial manufacturing processes, but catalytic activity on solid surfaces is poorly understood. This is especially true for the cellulase enzymes used to release fermentable sugars from cellulosic biomass for the production of advanced biofuels. Now, researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) through support from the Energy Biosciences Institute (EBI) have literally shed new light on cellulase catalysis.

Using an ultrahigh-precision visible light microscopy technique called PALM – for Photo-Activated Localization Microscopy – the researchers have found a way to improve the collective catalytic activity of enzyme cocktails that can boost the yields of sugars for making fuels. Increasing the sugar yields from cellulosic biomass to help bring down biofuel production costs is essential for the widespread commercial adoption of these fuels. (more…)

A new approach to spinal muscular atrophy?

Spinal muscular atrophy is a debilitating neuromuscular disease that in its most severe form is the leading genetic cause of infant death. By experimenting with an ALS drug in two very different animal models, researchers at Brown University and Boston Children’s Hospital have identified a new potential mechanism for developing an SMA treatment.

PROVIDENCE, R.I. [Brown University] — There is no specific drug to treat spinal muscular atrophy (SMA), a family of motor neuron diseases that in its most severe form is the leading genetic cause of infant death in the United States and affects one in 6,000 people overall. But a new multispecies study involving a drug that treats amyotrophic lateral sclerosis (ALS) has pinpointed a mechanism of SMA that drug developers might be able to exploit for a new therapy.

PASADENA, Calif. – NASA’s Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn’s north pole.

In high-resolution pictures and video, scientists see the hurricane’s eye is about 1,250 miles (2,000 kilometers) wide, 20 times larger than the average hurricane eye on Earth. Thin, bright clouds at the outer edge of the hurricane are traveling 330 mph(150 meters per second). The hurricane swirls inside a large, mysterious, six-sided weather pattern known as the hexagon.

Research Finds Invasive Kudzu Bugs May Pose Greater Threat Than Previously Thought

The invasive kudzu bug has the potential to be a major agricultural pest, causing significant damage to economically important soybean crops. Conventional wisdom has held that the insect pests will be limited to areas in the southern United States, but new research from North Carolina State University shows that they may be able to expand into other parts of the country.

Kudzu bugs (Megacopta cribraria) are native to Asia, and were first detected in the U.S. in Georgia in 2009. They have since expanded their territory as far north as Virginia. The bugs have an interesting life cycle, which has been thought to be a limiting factor on far they can spread. (more…)

With the 2015 sesquicentennial of Abraham Lincoln’s death approaching, interest is rising, and with new tools, UA researchers have turned their attention to one of the last remaining mysteries about what reportedly was the largest traditional funeral in American history – the train’s color.

A trove of information exists about Abraham Lincoln’s funeral, which drew millions of mourners during a two-week railway procession across the Northern states.

But until now, the precise color of the president’s railcar had been lost to history. (more…)

Read the improbable story of a Microsoft employee who twice turned down a traditional tech sector job so he could teach high school students, and then landed his dream job.

REDMOND, Wash. — Kevin Wang could have followed his career.

Instead, he chose to follow his calling.

It was the early 2000s, and Wang had just graduated from Berkeley with a degree in computer science and electrical engineering. He was trying to decide which tech company he should offer his services to, when a high school came calling. (more…)
