Infrared data on Tropical Storm Emang's cloud top temperatures was captured by the Atmospheric Infrared Sounder (AIRS) instrument on Jan. 15 at 0823 UTC (3:23 a.m. EST). AIRS data showed that the largest area of powerful thunderstorms were in the northern half of the storm. That area showed cold cloud top temperatures of -63F (-52C) indicating high, powerful thunderstorms where the heaviest rain was falling.

The AIRS data also showed that sinking air or subsidence was occurring in the southwestern quadrant of the storm, which is weakening the convection there.
AIRS data also showed that the low level center of circulation had become slightly elongated, stretching from southwest to northeast. For a tropical cyclone to intensify, its circulation centers from the surface to upper atmosphere basically have to stack up. When the center becomes elongated the storm usually has a difficult time intensifying.
On Jan. 15 at 0900 UTC, Tropical Storm Emang's maximum sustained winds were near 35 knots (40.2 mph/64.8 kph). Emang is moving slowly to the south-southwest at 4 knots (4.6 mph/7.4 kph). Emang was centered near 13.5 south latitude and 78.6 east longitude, about 525 nautical miles (604.2 miles/ 972.3 km) southeast of Diego Garcia. Diego Garcia is a coral atoll in the central southern Indian Ocean.
Forecasters at the Joint Typhoon Warning Center expect atmospheric conditions to improve over the coming days, so that Emang can organize and strengthen. Fortunately, the storm is no threat to land.Text Credit: Rob Gutro

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.
RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...
Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.
To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
