Anyone concerned by the idea that people might try to combat global warming by injecting tons of sulfate aerosols into Earth’s atmosphere may want to read an article in the May 1 issue of the journal Geology.

GOES-16, the most advanced weather satellite NOAA has ever developed, will be moved to the GOES-East position at 75 degrees west longitude, once it is declared operational in November. Top officials from NOAA announced the long-awaited decision at today’s 2017 Atlantic Hurricane Season Outlook news conference in College Park, Maryland.

By observing the soot particles formed in a simple flame, researchers at KAUST have developed a computational model capable of simulating soot production inside the latest gasoline automobile engines.

Although today’s passenger vehicle engines are cleaner than ever before, their exhaust can still contain significant numbers of nanoscopic soot particles that are small enough to penetrate the lungs and bloodstream. This new computer model should help car makers improve their engines to cut soot formation.

Engineers at the University of California, Riverside have developed a new way to recover almost 100 percent of the water from highly concentrated salt solutions. The system will alleviate water shortages in arid regions and reduce concerns surrounding high salinity brine disposal, such as hydraulic fracturing waste.

Early science results from NASA's Juno mission to Jupiter portray the largest planet in our solar system as a complex, gigantic, turbulent world, with Earth-sized polar cyclones, plunging storm systems that travel deep into the heart of the gas giant, and a mammoth, lumpy magnetic field that may indicate it was generated closer to the planet's surface than previously thought.

"We are excited to share these early discoveries, which help us better understand what makes Jupiter so fascinating," said Diane Brown, Juno program executive at NASA Headquarters in Washington. "It was a long trip to get to Jupiter, but these first results already demonstrate it was well worth the journey."

On Oct.13, 2014 something very strange happened to the camera aboard NASA’s Lunar Reconnaissance Orbiter (LRO). The Lunar Reconnaissance Orbiter Camera (LROC), which normally produces beautifully clear images of the lunar surface, produced an image that was wild and jittery. From the sudden and jagged pattern apparent in the image, the LROC team determined that the camera must have been hit by a tiny meteoroid, a small natural object in space.   

LROC is a system of three cameras mounted on the LRO spacecraft. Two Narrow Angle Cameras (NACs) capture high resolution black and white images. The third Wide Angle Camera captures moderate resolution images using filters to provide information about the properties and color of the lunar surface. 

The shells of marine organisms take a beating from impacts due to storms and tides, rocky shores, and sharp-toothed predators. But as recent research has demonstrated, one type of shell stands out above all the others in its toughness: the conch.

Now, researchers at MIT have explored the secrets behind these shells’ extraordinary impact resilience. And they’ve shown that this superior strength could be reproduced in engineered materials, potentially to provide the best-ever protective headgear and body armor.

Changing the natural electrical signaling that exists in cells outside the nervous system can improve resistance to life-threatening bacterial infections, according to new research from Tufts University biologists.  The researchers found that administering drugs, including those already used in humans for other purposes, to make the cell interior more negatively charged strengthens tadpoles’ innate immune response to E. coli infection and injury. This reveals a novel aspect of the immune system – regulation by non-neural bioelectricity – and suggests a new approach for clinical applications in human medicine. The study is published online May 26, 2017, in npj Regenerative Medicine, a Nature Research journal.

“All cells, not just nerve cells, naturally generate and receive electrical signals. Being able to regulate such non-neural bioelectricity with the many ion channel and neurotransmitter drugs that are already human-approved gives us an amazing new toolkit to augment the immune system’s ability to resist infections,” said the paper’s corresponding author Michael Levin, Ph.D., Vannevar Bush professor of biology and director of the Allen Discovery Center at Tufts and the Tufts Center for Regenerative and Developmental Biology in the School of Arts and Sciences. Levin is also an associate faculty member of the Wyss Institute of Biologically Inspired Engineering at Harvard University.

Just as Cinderella turned from a poor teenager into a magnificent princess with the aid of a little magic, scientists at the U.S. Department of Energy’s Argonne National Laboratory have transformed a common metal into a useful catalyst for a wide class of reactions, a role formerly reserved for expensive precious metals.

In a new study, Argonne chemist Max Delferro boosted and analyzed the unprecedented catalytic activity of an element called vanadium for hydrogenation – a reaction that is used for making everything from vegetable oils to petrochemical products to vitamins. 

What to do proteins and Kevlar have in common? Both feature long chain molecules that are strung together by amide bonds. These strong chemical bonds are also common to many other naturally occurring molecules as well as man-made pharmaceuticals and plastics. Although amide bonds can give great strength to plastics, when it comes to their recycling at a later point, the difficultly of breaking these bonds usually prevents recovery of useful products. Catalysts are widely used in chemistry to help speed up reactions, but breaking the kinds of amide bonds in plastics, such as nylon, and other materials requires harsh conditions and large amounts of energy.
