The wind shear lessened, and Philippe became a hurricane today, after 12 days of moving across the Atlantic Ocean. NASA's TRMM satellite saw towering thunderstorms and intense rainfall within Philippe yesterday, which provided forecasters with a clue that the storm was strengthening. Philippe reached hurricane status this morning, Oct. 6, 2011.

Over two days, the Tropical Rainfall Measuring Mission (TRMM) satellite provided forecasters with cloud heights and rainfall rates occurring within Tropical Storm Philippe. TRMM is managed by both NASA and the Japanese Space Agency, JAXA.
The National Hurricane Center (NHC) upgraded Philippe to a hurricane at 1500 UTC (11 a.m. EDT) on Thursday, October 6 2011. Earlier TRMM Microwave Imager (TMI) data from October 6, 2011 at 0024 UTC (Oct. 5 at 8:24 p.m. EDT) showed that tropical storm Philippe's center of circulation had become better defined and an eyewall was forming. Microwave satellite imagery also shows an eye-like feature, while the visible imagery from NOAA's GOES satellite hints at the indication of an eye, although mostly covered with clouds.
On Oct. 6, Philippe's maximum sustained winds were near 80 mph (130 kmh). Philippe is a Category One hurricane on the Saffir-Simpson scale, but some weakening is forecast in the next two days. Philippe is located about 425 miles (680 km) southeast of Bermuda, near 27.8 North and 60.0 West. The hurricane is moving to the north-northeast near 9 mph (15 kmh) and is expected to move toward the northeast and speed up.
The TRMM satellite also had an excellent look at Philippe earlier on Wednesday, October 5, 2011 at 1752 UTC (1:52 p.m. EDT). TRMM's Precipitation Radar (PR) scanned directly over Philippe and revealed that Philippe had bands of intense rainfall that around the southeast side of the center of circulation.
A 3-D rendering of that TRMM PR data showed deep convective towers reached to heights of over 13km (~8 miles). Previous research from NASA scientists show that whenever these "hot towers" are spotted within a tropical cyclone, the storm typically intensifies within six hours, and Philippe became a hurricane today.

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...
