NASA's Aqua satellite passed over Australia today, Feb. 16 at 05:17 UTC (12:17 a.m. EST/ 2:47 p.m. Australia/Darwin local time. The Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of both tropical storms and found each to have strong convection (rapidly rising air that forms the thunderstorms that power a tropical cyclone). Convection was so strong in Carlos and Dianne that the cloud tops of the thunderstorms within were as cold as or colder than -52 Celsius/ -63 Fahrenheit.

A Cyclone Warning for Carlos is in effect for coastal areas from Daly River Mouth to Goulburn Island, including Darwin, Croker Island and the Tiwi Islands. A Cyclone Watch continues for coastal areas from Port Keats to Daly River Mouth. The Joint Typhoon Warning Center and Australian Bureau of Meteorology expect Carlos to eventually track southwest over land for the next several days.
Near Western Australia, System 97S intensified into Tropical Storm Dianne overnight. On Feb. 16 at 1500 UTC (10 a.m. EST/12:30 a.m. Feb. 17, Australia/Darwin local time), Tropical Storm Dianne had maximum sustained winds near 40 knots (46 mph / 74 kmh). It was still over open waters in the Southern Indian Ocean, near 18.9 South latitude and 111.3 East longitude, about 250 nautical miles (287 miles/463 km) northwest of Learmonth, Australia.
A Cyclone Watch is currently in effect for coastal areas of Western Australia from Exmouth to Cape Cuvier. During the morning hours (Eastern Time/U.S.) bands of showers were pushing southeast from Dianne from Pardoo (in the east) through Port Hedland southwest to Exmouth. It is currently drifting to the northeast but is expected to loop and move south then southwest after the next day or two.
The Joint Typhoon Warning Center expects Dianne to continue strengthening under an environment of warm sea surface temperatures and low wind shear for the next three days before running into adverse conditions. During that time, however, it is forecast to reach hurricane force and bring gusty winds and heavy rainfall to Learmonth as its center passes to the west.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
