Scientists are continually exploring different aspects of hurricanes to increase the understanding of how they behave. Recently, two NASA-funded scientists from Florida State University analyzed ozone levels surrounding hurricanes. Their work could lead to better methods of forecasting the paths of the deadly storms.
In their study, FSU meteorologists Xiaolei Zou and Yonghui Wu found that variations of ozone levels from the surface of the ocean to the upper atmosphere are closely related to the formation, intensification and movement of a hurricane. In studying meteorological data from 12 such storms, Zou and Wu noticed that over an area of 100 miles, the area surrounding each hurricane typically had low levels of ozone from the surface to the top of the storm. Whenever the hurricane intensified, the ozone levels throughout the storm decreased even more.
In addition, when Zou and Wu examined hurricanes using the ozone data, the eye of the storms became very clear. Because forecasters always try to pinpoint the eye of the hurricane, this knowledge will help with locating a storms exact position and possibly lead to better tracking.

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...
