Light-Driven Reaction Converts Carbon Dioxide into Fuel
February 24, 2017 04:26 PM - Duke University

Duke University researchers have developed tiny nanoparticles that help convert carbon dioxide into methane using only ultraviolet light as an energy source.

Having found a catalyst that can do this important chemistry using ultraviolet light, the team now hopes to develop a version that would run on natural sunlight, a potential boon to alternative energy.

Diamond's 2-billion-year growth charts tectonic shift in early Earth's carbon cycle
February 24, 2017 02:56 PM - Europlanet

A study of tiny mineral ‘inclusions’ within diamonds from Botswana has shown that diamond crystals can take billions of years to grow. One diamond was found to contain silicate material that formed 2.3 billion years ago in its interior and a 250 million-year-old garnet crystal towards its outer rim, the largest age range ever detected in a single specimen. Analysis of the inclusions also suggests that the way that carbon is exchanged and deposited between the atmosphere, biosphere, oceans and geosphere may have changed significantly over the past 2.5 billion years.

Scientific team develops nano-sized hydrogen storage system to increase efficiency

Inside NASA's Goddard Space Flight Center in Greenbelt, Maryland the James Webb Space Telescope team completed the environmental portion of vibration testing and prepared for the acoustic test on the telescope. 

Cosmic blast from the past
February 24, 2017 10:47 AM - ESA/Hubble Information Centre

Three decades ago, a massive stellar explosion sent shockwaves not only through space but also through the astronomical community. SN 1987A was the closest observed supernova to Earth since the invention of the telescope and has become by far the best studied of all time, revolutionising our understanding of the explosive death of massive stars.

Do Cats Cause Schizophrenia? Believe the Science, Not the Hype
February 24, 2017 10:37 AM - Nick Stockton, Wired

Cats, you might have heard, cause schizophrenia. Or—more recently—they do nothing of the sort. It’s a decades-long scientific investigation, infrequently punctuated by headline-grabbing stories that definitively claim one or the other, depending on whatever the newest sliver of research indicates.

Researchers develop math models to address antibiotic resistance in healthcare facilities
February 24, 2017 08:10 AM - York University

Scientists at York University and a national team of collaborators have developed new mathematical models that will help researchers, doctors and policymakers address the challenging public health issue of antibiotic resistance in bacteria. The research, co-led by postdoctoral fellows Josie Hughes and Xi Huo, was published in the journal PLOS ONE.

Researchers find new clues for nuclear waste cleanup
February 23, 2017 05:31 PM - Washington State University

A Washington State University study of the chemistry of technetium-99 has improved understanding of the challenging nuclear waste and could lead to better cleanup methods.

The work is reported in the journal Inorganic Chemistry. It was led by John McCloy, associate professor in the School of Mechanical and Materials Engineering, and chemistry graduate student Jamie Weaver. Researchers from Pacific Northwest National Laboratory (PNNL), the Office of River Protection and Lawrence Berkeley National Laboratory collaborated.

Study Targets Warm Water Rings that Fuel Hurricane Intensification in the Caribbean Sea
February 23, 2017 10:05 AM - Miami Rosenstiel School of Marine & Atmospheric Science

Last year’s devastating category-5 hurricane—Matthew—may be one of many past examples of a tropical storm fueled by massive rings of warm water that exist in the upper reaches of the Caribbean Sea.
