Clouds are an important part of the Arctic climate because they trap warm air at the surface like a blanket. There has been a continuous increase in cloud cover over the Arctic for the past two decades and this is driving big changes on land and in the ocean. The increasing cloud cover has exacerbated the Arctic amplification and is a major reason why the Arctic is warming twice as fast as the rest of the planet.

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.

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.

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.”

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.
