New study shows banning shark fin in the U.S. won't help save sharks

A new study published today in the scientific journal Marine Policy shows that banning the sale of shark fins within the United States can actually harm ongoing shark conservation efforts.

David Shiffman of SFU’s Earth2Ocean research group and Robert Hueter from the Center for Shark Research at Mote Marine Laboratory in Florida say that a proposed nationwide ban on shark fin sales within the United States is a misguided and ineffective approach to protecting sharks.

One vaccine injection could carry many doses

MIT engineers have invented a new 3-D fabrication method that can generate a novel type of drug-carrying particle that could allow multiple doses of a drug or vaccine to be delivered over an extended time period with just one injection.

The new microparticles resemble tiny coffee cups that can be filled with a drug or vaccine and then sealed with a lid. The particles are made of a biocompatible, FDA-approved polymer that can be designed to degrade at specific times, spilling out the contents of the “cup.”

NASA Sees Eastern Pacific Stir Up Tropical Storm Norma

Tropical Storm Norma is the newest addition to the tropical cyclones in the Eastern Pacific and NASA's Terra satellite caught it after it developed.

New climate risk classification created to account for potential 'existential' threats

A new study evaluating models of future climate scenarios has led to the creation of the new risk categories “catastrophic” and “unknown” to characterize the range of threats posed by rapid global warming. Researchers propose that unknown risks imply existential threats to the survival of humanity.

These categories describe two low-probability but statistically significant scenarios that could play out by century’s end, in a new study by Veerabhadran Ramanathan, a distinguished professor of climate and atmospheric sciences at Scripps Institution of Oceanography at the University of California San Diego, and his former Scripps graduate student Yangyang Xu, now an assistant professor at Texas A&M University.

NASA Sees Typhoon Doksuri in the South China Sea

Typhoon Doksuri appeared well-rounded and organized on satellite imagery as it moved through the north central South China Sea toward Vietnam.

The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible light image of Typhoon Doksuri on Sept. 14, 2017 at 1:48 a.m. EDT (0548 UTC).Although Doksuri's eye was obscured by high clouds, the center was evident by the powerful thunderstorms that surrounded it. Doksuri's western quadrant had already spread over the east coast of Vietnam as it moved toward that country.

Biologist reaches into electric eel tank, comes out with equation to measure shocks

The shock from a young electric eel feels like accidentally touching a horse fence. A big one is more like getting tasered — by nine of those devices at once.

NASA-NOAA Satellite Spots 2 Tails of Hurricane Max

NASA-NOAA's Suomi NPP satellite captured an image of the latest tropical cyclone in the Eastern Pacific on Sept. 13 along the southwestern coast of Mexico. After Max formed as a tropical storm, it appeared to have two "tails." Max strengthened into a hurricane on Sept. 14.

Max formed as a depression on Sept. 13 around 11 a.m. EDT. It was the sixteenth tropical depression of the Eastern Pacific Ocean hurricane season. By 5 p.m. EDT it had strengthened into a tropical storm.   

Investigating a big dam concrete problem

When the Mactaquac Dam opened in New Brunswick, Canada, in 1968, it was expected to have a service life of 100 years, but a chemical reaction occurring within the concrete used to build the dam has drastically shortened that timeline.

SLAC-Led Project Will Use Artificial Intelligence to Prevent or Minimize Electric Grid Failures

A project led by the Department of Energy’s SLAC National Accelerator Laboratory will combine artificial intelligence with massive amounts of data and industry experience from a dozen U.S. partners to identify places where the electric grid is vulnerable to disruption, reinforce those spots in advance and recover faster when failures do occur.

Corrosion in Real Time

What affects almost everything made of metal, from cars to boats to underground pipes and even the fillings in your teeth? Corrosion — a slow process of decay. At a global cost of trillions of dollars annually, it carries a steep price tag, not to mention, the potential safety, environmental and health hazards it poses.
