On Oct. 11 at 11 a.m. EDT the National Hurricane Center (NHC) announced the formation of tropical depression sixteen (TD16) northeast of the Bahamas. Earlier, at 0422 UTC (12:22 a.m. EDT), the Tropical Rainfall Measuring Mission (TRMM) satellite had a look at the disturbed weather associated with the formation of TD16. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) indicated that surface precipitation was falling at a rate of up to 20mm per hour (~0.8 inches per hour) in the northwestern part of this small area of low pressure.
This visible image of Tropical Storm Patty was taken by the MODIS instrument aboard NASA's Terra satellite on Oct. 11 at 1515 UTC (11:15 a.m. EDT). Strongest storms around the center cast shadows on lower surrounding thunderstorms.

TRMM precipitation radar data was used to create a 3-D view of the storm that showed that a few of the most powerful convective storms called "hot towers" in the developing tropical depression were reaching altitudes of over 16km (~9.9 miles). NASA research has shown that whenever hot towering thunderstorms are spotted within a tropical cyclone, the storm intensifies within about six hours, and the low pressure area did, becoming Tropical Depression 16. It also intensified further into Tropical Storm Patty by 5 p.m. EDT that day.
The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Terra satellite also captured a visible image of Tropical Depression 16 on Oct. 11. Terra passed over Tropical Depression 16 at 1515 UTC (11:15 a.m. EDT) just six hours before it strengthened into Tropical Storm Patty. Strongest storms around the center cast shadows on lower surrounding thunderstorms indicating that the storm continued to generate a large mass of deep convection.
On Friday, Oct. 12, Patty was drifting at 3 mph (6 kph) south-southwestward near the Bahamas and was already weakening. Tropical Storm Patty had maximum sustained winds near 40 mph (65 kph). Patty's center was located near 25.1 North latitude and 72.5 West longitude, about 230 miles (375 km) east-northeast of the central Bahamas. The National Hurricane Center (NHC) expects Patty to move slowly to the south-southwest or southwest and speed up on Sunday, Oct. 14 while continuing to weaken. In fact, the NHC noted that Patty could become a remnant low pressure area on Saturday, Oct. 13.
Dry and more stable air wrapping around Tropical Storm Patty is the factor that is expected to weaken the storm. The NHC forecasters noted that a low-level ridge (elongated area) of high pressure is building up (strengthening) over the western Atlantic Ocean, and that's going to increase the winds shear from the southwest over the weekend of Oct. 13 and 14, so Patty is likely going to be blown apart in the next day or two.Text credit: Rob Gutr/Hal Pierceo

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
