NASA Sees Hurricane Max Make Landfall and Weaken

NASA’s Aqua satellite captured in infrared-light image of Hurricane Max that showed the storm weakened quickly as it made landfall in southwestern Mexico. Max quickly degenerated into a large area of low pressure.

Poor Sleep Hastens Progression of Kidney Disease

People with chronic kidney disease may be especially vulnerable to the deleterious effects of poor sleep, according to a new paper published in the Journal of the American Society of Nephrology.

Skin Patch Dissolves "Love Handles" in Mice

Researchers have devised a medicated skin patch that can turn energy-storing white fat into energy-burning brown fat locally while raising the body’s overall metabolism. The patch could be used to burn off pockets of unwanted fat such as “love handles” and treat metabolic disorders, such as obesity and diabetes, according to researchers at Columbia University Medical Center (CUMC) and the University of North Carolina.

New Orleans Greenery Post-Katrina Reflects Social Demographics More Than Storm Impact

Popular portrayals of “nature reclaiming civilization” in flood-damaged New Orleans, Louisianna, neighborhoods romanticize an urban ecology shaped by policy-driven socioecological disparities in redevelopment investment, ecologists argue in a new paper in the Ecological Society of America’s open access journal Ecosphere.

Wolves Understand Cause and Effect Better Than Dogs

A rattle will only make noise if you shake it. Children learn this principle of cause and effect early on in their lives. However, animals like the wolf also understand such connections and are better at this than their domesticated descendants. Researchers at the Wolf Science Center of the Vetmeduni Vienna say that wolves have a better causal understanding than dogs and that they follow human-given communicative cues equally well. The study in Scientific Reports provides the insight that the process of domestication can also affect an animal’s causal understanding.

The Body's Own Fat-Metabolism Protects Against the Harmful Effects of Sugar

For several years, medical researchers, doctors and dieticians have known that a low carbohydrate diet and plentiful fat can prevent a range of lifestyle and age-related diseases and thus promote healthy aging. But researchers from around the world have not been able to explain why this is the case. They have just been reasonably certain that the energy metabolism and its chemical intermediates (metabolites) play a central role.

Arctic Sea Ice Once Again Shows Considerable Melting

This September, the extent of Arctic sea ice shrank to roughly 4.7 million square kilometres, as was determined by researchers at the Alfred Wegener Institute, the University of Bremen and Universität Hamburg. Though slightly larger than last year, the minimum sea ice extent 2017 is average for the past ten years and far below the numbers from 1979 to 2006. The Northeast Passage was traversable for ships without the need for icebreakers.

Why is it getting cloudier in the Arctic?

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.

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.”
