Last week, Igor was a tropical storm who faded into a tropical depression. The National Hurricane Center had forecast that over the weekend Igor would approach more favorable conditions (low wind shear and warm sea surface temperatures) causing it to strengthen into a hurricane and it did. Tropical storm Igor was upgraded by the National Hurricane Center (NHC) in Miami, Florida to a hurricane on Sunday, September 12 at 0300 UTC (Sept. 11 at 11 p.m. EDT) .
TRMM on Sept. 12 at 0504 UTC (1:04 a.m. EDT) captured an image of Hurricane Igor\'s rainfall, and there was a lot of heavy rain falling (red) at over 2 inches per hour.

On Sept. 13 at 11 a.m. EDT, Igor had maximum sustained winds near 150 mph and was a Category 4 hurricane on the Saffir-Simpson scale. The center of Hurricane Igor was located 880 miles east of the Northern Leeward Islands near latitude 17.5 north and longitude 49.7 west. Igor is moving toward the west near 10 mph and a turn toward the west-northwest is expected tonight or tomorrow. Estimated minimum central pressure is 933 millibars.
Igor is expected to remain a major hurricane for a couple of days.

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...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
