NASA-NOAA's Suomi NPP satellite passed over former Tropical Storm Grace and saw the storm had weakened into an open wave of low pressure. Wind data from NASA's RapidScat was also used to confirm Grace's degeneration.
NASA-NOAA's Suomi satellite flew over Grace at 4:45 UTC (12:45 a.m. EDT) on Sept. 9 and the VIIRS instrument aboard captured an infrared image of the storm. Satellite data showed Grace no longer had a closed circulation and is now an open wave.
At 11 a.m. EDT (1500 UTC), on September 9, the remnants of Grace were located near latitude 14.5 North and longitude 49.0 West. That puts Grace's remnants about 825 miles (1,325 km) east of the Lesser Antilles.
The remnants were moving toward the west near 18 mph (30 kph) and this general motion is expected to continue over the next couple of days. Maximum sustained winds were near 30 mph (45 kph) with higher gusts. The National Hurricane Center said that "little change in strength is expected over the next day or two." The estimated minimum central pressure is 1008 millibars.
NHC Forecaster Pasch noted that "Data from the Rapidscat instrument onboard the International Space Station showed that there were no longer any westerly surface winds in Grace. This was confirmed by animation of high-resolution visible imagery that showed no westerly low-cloud motions." Since Grace had opened up into a wave, the National Hurricane Center issued its final advisory.
Grace's remnant wave is expected to continue moving quickly to the west. NHC noted that the remnants could produce some gusty winds and showers over portions of the Lesser Antilles within a couple of days.

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...
