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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
