Infrared satellite imagery from NASA's Aqua satellite have revealed that the clouds around Hurricane Chris' eye have reached a cold peak early on June 21 when it was first designated a hurricane, and have since warmed.

The thunderstorms that surround Chris' eye are now between -60 and -70 Celsius. Cloud top temperatures that cold indicate strong, high, thunderstorms with the potential for heavy rainfall.
When thunderstorm cloud tops cool, it means there's more uplight in the atmosphere, which can push cloud tops higher and build stronger thunderstorms. When cloud top temperatures warm, it means the cloud tops are falling, and the push of the air upward is lesser than it was before, and the storm is weakening. As a result, forecasters at the National Hurricane Center expect Chris to become a post-tropical cyclone on Friday, June 22. That weakening is expected because Chris is moving into stable air and cooler waters.
NOAA's GOES-13 satellite captured a visible image of Chris on June 21 at 1445 UTC (10:45 a.m. EDT). The image was created by NASA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. and it showed Hurricane Chris with a tight circulation center.
At 11 a.m. EDT, Chris had 75 mph (120 kph) winds. It was located about 625 miles (1005 km) southeast of Cape Race, Newfoundland, Canada, near 41.1 North and 43.2 West. It was moving to the northeast at 20 mph (32 kph) and had a minimum central pressure of 987 millibars.
Chris is expected to turn in the Altantic over the next couple of days. First a turn to the north and then northwest and finally south. Chris is moving around a large mid-to-upper level low pressure area and will eventually become absorbed within the upper level low in the next couple of days.

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...
