NASA research indicates that whenever a hot tower is spotted, a tropical cyclone will likely intensify. Less than 14 hours after the TRMM satellite captured an image of Ileana's rainfall and cloud heights, Ileana strengthened into a hurricane on Aug. 29.
NASA's TRMM satellite captured a view of Ileana's rainfall rates on Aug. 29 at 2:17 a.m. EDT. The purple areas indicated the heaviest rainfall rates, near 70 mm (2.7 inches) per hour. Some hot towering clouds around the center of circulation (also in purple) were higher than 9.3 miles (15 km). Credit: NASA/SSAI, Hal Pierce
NASA's Tropical Rainfall Measuring Mission (TRMM) satellite captured a view of Ileana's rainfall rates on Aug. 29 at 2:17 a.m. EDT and saw the heaviest rainfall rates, near 50 mm (2.0 inches) per hour in a band of thunderstorms southeast of the center of circulation. TRMM identified some hot towering clouds around the center of circulation that were higher than 9.3 miles (15 km).
On Aug. 30, satellite data showed a ragged double eyewall in the center of circulation. On Aug. 30 at 11 a.m. EDT, Hurricane Ileana's maximum sustained winds had increased to near 80 mph (130 kmh). Hurricane force winds extend outward up to 25 miles (35 km) from the center, which makes Ileana's hurricane-force wind area about 15 miles larger than Hurricane Kirk's in the Atlantic Ocean today. Ileana's tropical storm force winds extend outward up to 90 miles (150 km).The National Hurricane Center expects that Ileana won't strengthen much more before weakening on Aug. 31.
Ileana's center was about 305 miles (495 km) southwest of the southern tip of Baja California, Mexico, near latitude 20.2 north and longitude 113.7 west. Ileana is moving toward the northwest near 8 mph (13 kmh) and into cooler waters that will sap her strength.
The National Hurricane Center expects Ileana to weaken to a remnant low pressure area over the weekend of Sept. 1-2, while drifting west, and away from land.Text credit: Rob Gutro

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...
