After coming ashore on April 11, Tropical Cyclone Ita dropped heavy rainfall over the weekend that caused flooding in many areas of northeastern Australia's state of Queensland. The Tropical Rainfall Measuring Mission satellite known as TRMM gathered data on rainfall that was used to create a rainfall map at NASA.
TRMM is a satellite managed by both NASA and JAXA, the Japan Aerospace Exploration Agency. At NASA's Goddard Space Flight Center in Greenbelt, Md. Hal Pierce created a TRMM-based near-real time Multi-satellite Precipitation Analysis (TMPA).
The TMPA precipitation data covered the period from April 1 to 14, 2014 which starts when Ita formed in the Coral Sea and moved along northeastern Australia's coast. This TRMM satellite rainfall map estimated that some of the largest isolated rainfall totals were near 400 mm/15.7 inches west of both Ingham and Townsville, Queensland.
A 3-D image of Ita was made at NASA using data collected by the TRMM satellite on April 14, 2014 at 0416 UTC/12:16 a.m. EDT after the tropical storm moved back into the Coral Sea.
TRMM's Precipitation Radar (PR) instrument found that the weakening tropical cyclone was still dropping rainfall at a maximum rate of over 161 mm/6.3 inches per hour over the Coral Sea. The 3-D image, created using TRMM PR data, showed that some storms within Ita were still reaching heights of over 13 km/8 miles as it was becoming extra-tropical.
Another NASA-shared satellite captured a visible look at Ita's remnants on April 15. The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a look at the dying extra-tropical storm. VIIRS collects visible and infrared imagery and global observations of land, atmosphere, cryosphere and oceans.
When Suomi flew over Extra-Tropical Storm Ita on April 15 at 3:53 UTC/April 14 at 11:53 p.m. EDT, VIIRS visible data revealed that Ita's structure had elongated more than the previous day. The VIIRS image showed that strong northwesterly wind shear continued to hammer the storm because the bulk of the storm's clouds were pushed southeast of the center. Ita's remnants have taken on more of a frontal appearance today as they continue to weaken at sea.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
