NASA's Aqua satellite passed over Tropical Cyclone Bansi on January 12 as it was intensifying rapidly and saw a cloud-covered eye in the storm's center. Bansi has triggered warnings for the island of Mauritius and is expected to continue intensifying while passing it.
On Sunday, January 11, Tropical Cyclone Bansi formed north of La Reunion Island in the Southern Indian Ocean and triggered two alerts. A tropical cyclone warning class I was posted at Mauritius, and a Yellow pre-alert went into effect for La Reunion Island. At 0900 UTC (4 a.m. EST) Tropical Cyclone Bansi (formerly System 92S) was located about 254 nautical miles north of St Denis, La Reunion Island. It was slowly moving to the east-southeast and had maximum sustained winds near 35 knots (40 mph/62 kph).
On January 11 at 06:40 UTC (1:40 a.m. EST) the MODIS instrument aboard NASA's Terra satellite captured an image of Tropical Cyclone Bansi. The MODIS image showed strong thunderstorms tightly wrapped around the center, and a large, wide band of thunderstorms in the storm's eastern quadrant spiraling around the storm and into the center from the west.
By January 12 at 10:10 UTC (5:10 a.m. EST) when the MODIS instrument aboard NASA's Aqua satellite passed overhead, the storm had rapidly consolidated and the bands of thunderstorms circling the center had expanded. Bands of thunderstorms spiraling around the storm wrapped around the storm from the northwest to the southeast and finally wrapping into the center from the west. The eye of the storm appeared covered by high clouds.
In Mauritius, the warnings on January 12 were changed to a tropical cyclone warning class 2. La Reunion, which lies to the southwest of Mauritius and is farther from the storm remained on Yellow pre-alert.
In less than 24 hours after it formed, Bansi strengthened from a minimal tropical storm into a major hurricane (Category 3) with maximum sustained winds. A Category three hurricane on the Saffir-Simpson wind scale has sustained winds from 111 to 129 mph (96 to 112 knots/178 to 208 kph).
At 0900 UTC (4 a.m. EST) on January 12, Bansi had maximum sustained winds near 100 knots (115.1. mph/185.2 kph). Bansi was centered near 17.2 south latitude and 56.1 east longitude, about 191 nautical miles (219.8 miles/ 353.7 km) north-northwest of Port Louis, Mauritius, has tracked eastward at 7 knots (8.0 mph/12.9 kph).
The Joint Typhoon Warning Center noted that Bansi continued to rapidly intensify as a result of passage over warm water, low vertical wind shear, and outflow aloft. A tropical cyclone needs good outflow (where winds spread out at the top of the hurricane) to maintain strength. Outflow means that air spreads out over the top of the storm assisting in its development. When outflow is weakened, the storm weakens.
Bansi is moving eastward along the southern edge of a near-equatorial ridge (elongated area) of high pressure. Bansi is forecast to continue moving to the east then southeast while strengthening to 125 knots before running into atmospheric conditions and cooler waters that will weaken it.

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...

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.
