Drifting buoys & floats weather hurricanes for better storm prediction
While some are still cleaning up from the series of hurricanes that plowed through the Caribbean and southern United States this season, scientists supported by the Office of Naval Research are busily cleaning up valuable data collected during the storms. The rapid-fire hurricanes barely gave researchers time to rest between flights that took them into the hearts of Hurricanes Frances, Ivan, and Jeanne. As part of a project called CBLAST, for Coupled Boundary Layer/Air-Sea Transfer, researchers air-dropped specially designed instruments into the paths of the hurricanes--and into the hurricanes themselves.
"This season has seen a breakthrough in hurricane and oceanographic research," said ONR program manager Dr. Carl Friehe. "Real-time data sent back by the drifters and floats have created great interest among oceanographers, meteorologists, and hurricane forecasters." Project CBLAST-Hurricane focuses on the energy exchanges between the ocean and atmosphere during a hurricane, and how those interactions affect a storms intensity (a separate CBLAST component studies low-wind interactions). By better understanding these energy exchanges, scientists can develop better models to predict a hurricanes development. A hurricanes intensity determines the size of the storm surge of water that precedes it--which can pose a significant threat to ships in port.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
