NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on the Terra satellite captured a visible image of Tropical Storm Julia on Sept. 18 at 13:50 UTC (9:50 a.m. EDT) and noticed a large area of Saharan dust over the Atlantic Ocean, to Julia's east.
On Sept. 20 at 5 a.m. EDT, Julia was still holding on to tropical storm status with maximum sustained winds near 45 mph. Julia was located about 1,165 miles west of the Azores Islands near 35.5 North and 47.9 West. Julia is moving east-northeast near 9 mph and is forecast to speed up. Julia's estimated minimum central pressure is 998 millibars.
In addition to dealing with Saharan dust, Julia is dealing with wind shear created by massive Hurricane Igor far to her west. That westerly wind shear continues to push Julia's strongest convection (rapidly rising air that forms the thunderstorms that power her) to the east of Julia's center of circulation. When a tropical cyclone doesn't "stack up" line an upright column, it loses its uniform spin, and tends to weaken.
The National Hurricane Center expects Julia to fade into a remnant low in a day or two. Computer models show two different scenarios after that, as some see Julia could be absorbed in the massive circulation of Hurricane Igor, while others keep Julia separate and becoming extratropical before dissipating over cooler waters.
Meanwhile, as the curtain begins to drop on Julia in the eastern Atlantic, another low pressure system is in the wings to create its own show. There's a low about 400 miles west of the Cape Verde Islands that is showing signs of organization today. It's moving northwestward and has an 80% chance of becoming a tropical depression in the next 48 hours. That low is one that NAA satellites are keeping a close eye on.

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.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

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.
