Florida creates task force on sea-level rise

After years of mostly ignoring climate change, Florida lawmakers waded deeper into the matter on Tuesday , advancing a proposal that would create a statewide Office of Resiliency and establish a task force to begin looking into how best to protect the state's 1350 miles (2,173 kilometers) of coastline from rising oceans. It's a marked change from just a few years ago, when the issue of climate...

Why These Australia Fires Are Like Nothing We've Seen Before

SYDNEY -- In late October, lightning struck brittle earth on Gospers Mountain in New South Wales. The remains of trees bone dry from consecutive winters with little to no rain were ignited, and the fire quickly spread.Three months later, it is still burning.The Gospers Mountain fire, which became Australia's largest "megablaze" as it grew to link several separate fires, offers a...

Transformative 'green' accelerator achieves world's first 8-pass full energy recovery

Scientists from Cornell University and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory (BNL) have successfully demonstrated the world's first capture and reuse of energy in a multi-turn particle accelerator, where electrons are accelerated and decelerated in multiple stages and transported at different energies through a single beamline. This advance paves the way for...

A model ecosystem fish story

Have I got a fish story for you. Any angler beginning a yarn like that usually ends up spinning a tall tale, an exaggeration or bald-faced lie.

New study examines mortality costs of air pollution in US

A team of University of Illinois researchers estimated the mortality costs associated with air pollution in the U.S. by developing and applying a novel machine learning-based method to estimate the life-years lost and cost associated with air pollution exposure.

Determining the atomic structure of natural products more rapidly and accurately

Many drugs are derived from natural products. But before natural products can be exploited, chemists must first determine their structure and stereochemistry. This can be a major challenge, particularly when the molecules cannot be crystallized and contain only few hydrogen atoms. A new NMR-based method now simplifies the analysis and produces more accurate results.

New species of antibiotic-resistant bacteria found in infected wound

A hitherto unknown antibiotic-resistant bacteria species, in the same family as E. coli and Salmonella spp., has been found and classified in Sweden. The proposed taxonomic name of the species -- the first of the new genus -- is Scandinavium goeteborgense, after the city of Gothenburg, Sweden, where the bacterium was isolated and the research was done.
