AIRS, the Atmospheric Infrared Sounder instrument on Aqua, provides scientists with infrared satellite imagery. That imagery measures cloud top temperatures and sea surface temperatures. If the cloud tops in low pressure areas or tropical cyclones are colder than -63 degrees Fahrenheit, it indicates strong thunderstorms and strong convection (rapidly rising air that condenses and forms the thunderstorms that power tropical cyclones).

On May 27 at 1:35 a.m. EDT (05:35 UTC) AIRS imagery showed System 90E developing the trademark tropical cyclone approximately 205 nautical miles south of Salina Cruz, Mexico near 12.8 North and 94.5 West. AIRS infrared imagery indicated there were four areas of strong thunderstorms with very high, cold cloud tops around the center of circulation. Infrared satellite imagery indicates a slowly consolidating, broad low-level circulation center.
Winds in the area are estimated to be 20 to 25 knots (23-28 mph). System 90E is trudging west at 1 mph. The Joint Typhoon Warning Center noted that System 90E "is expected to continue consolidating over the next 24-36 hours. The potential for the development of a significant tropical cyclone within the next 24 hours is good."

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...
