The Tropical Rainfall Measuring Mission (TRMM) satellite data was used to create a 3-D image of Tropical Storm Nock-ten's rainfall and cloud heights as it passed overhead on July 25. Nock-ten had towering convective storms near their centers of circulation that extended to heights above 15km (~9.3 miles) with heavy rainfall, falling at 2 inches (50 mm) per hour.

The 3-D view was made from TRMM's Precipitation Radar (PR) data collected on July 25, 2011 at 1631 UTC (12:31 p.m. EDT). Nock-ten had towering convective storms near the center of circulation that extended to heights above 15 kilometers (~9.3 miles). These tall towers are associated with convective bursts and can be a sign of future strengthening because they indicate areas where energy is being released into the developing tropical storms. Even on July 25, tropical storm Nock-ten was affecting the eastern Philippines.
Warnings are still in effect in the Philippines today, July 27, as Nock-ten makes its exit. The Public storm warning signal #1 is in effect in the Luzon provinces of Aurora, Apayao, Cagayan, Pangasinan, Nueva Ecija, Northern Quezon, Zambales, Pampanga, Tarlac, Bulacan, Bataan, Rizal and Metro Manila. In addition, Public storm warning signal #2 is in effect for the Luzon provinces of Ilocos Norte & Sur, Abra, Kalinga, Isabela, Mt. Province, Ifugao, La Union, Benguet, Nueva Viscaya and Quirino.
According to the Manila Sun Star news, the third day of heavy rains from Nock-ten (locally named Juaning) caused flooding in the northeastern Philippines and is responsible for 24 deaths.
At 1500 UTC (11 a.m. EDT) on July 27 infrared imagery from the Atmospheric Infrared Sounder instrument on NASA's Aqua satellite indicated that Nock-ten's center moved off the coast of western Luzon. Tropical Storm Nock-ten's maximum sustained winds were still near 50 knots (57 mph/92 kmh). It was centered about 170 miles (273 km) north-northwest of Manila, near 17.4 North and 120.4 East. Tropical storm-force winds extend out to 70 miles (112 km) from the center. Nock-ten was moving to the northwest at 14 knots (16 mph/26 kmh), and is making its way out of Luzon and into the South China Sea.
The forecasters at the Joint Typhoon Warning center expect Nock-ten to strengthen and make a second landfall crossing over Hainan Island, China and finally landfalling in Vietnam.

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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
