Tropical Storm Oswald was hugging the southwestern coast of the Cape York Peninsula, Queensland, Australia when NASA's Aqua satellite first flew overhead on Jan. 21 at 0430 UTC (Jan. 20 at 11:30 p.m. EST). The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Aqua satellite captured a visible image of the storm that showed tight bands of thunderstorms. Those bands weakened the next day when MODIS captured a second visible image of the storm. At that time, Oswald's eastern quadrant was over land.
These two images of Tropical Storm Oswald show the storm's progression and deterioration over the Cape York Peninsula, Queensland. The MODIS instrument aboard NASA's Aqua satellite captured these on Jan. 21 and Jan. 22 as Oswald made landfall.

On Jan. 21 at 0600 UTC (1 a.m. EST), Oswald had maximum sustained winds near 35 knots (40 mph/64.8 kph). Oswald was centered near 15.8 south and 141.2 east, about 90 nautical miles (103.6 miles /166.7 km) east-northeast of Mornington Island, Australia. NASA MODIS imagery on Jan. 22 showed Oswald's center over the southwestern coast of the peninsula while monsoonal flow was bringing thunderstorms and heavy rainfall to the eastern side of the peninsula. Oswald's maximum sustained winds had dropped to 25 knots (28.7 mph/46.3 kph) on Jan. 22.
NASA also captured an infrared image of Tropical Storm Oswald on Jan. 22 at 0329 UTC with the Atmospheric Infrared Sounder (AIRS) instrument that also flies aboard NASA's Aqua satellite. AIRS data revealed cold cloud tops and strong storms associated with Oswald and a nearby monsoonal trough (elongated area of low pressure) stretched from Cairns north to Cooktown, and over Cape Melville and Lakefield National Parks on the eastern Cape York Peninsula.
At 0600 UTC (1 a.m. EST/U.S.) on Jan. 22, Oswald was downgraded to a remnant low pressure area. The center of circulation was located near 5.0 south latitude and 142.3 east longitude, about 185 nautical miles (213 miles/342.6 km) east-northeast of Mornington Island, Australia, and over the Cape York Peninsula. Infrared satellite data at that time showed the strongest storms were located in the northwestern quadrant. An image from NASA's Tropical Rainfall Measuring Mission (TRMM) satellite on Jan. 22 showed that the low-level center was now stretched across the Cape York Peninsula.
The Australian Bureau of Meteorology (ABM) noted at 10 p.m. Cairns local time (7 a.m. EST/U.S.), that ex-tropical Cyclone Oswald was located over eastern Cape York Peninsula approximately 70 km (43.5 miles) east of Cape Flattery. Oswald was moving southeast at 20 kph (12.4 mph). ABM noted that the monsoon trough (elongated area of low pressure) extended from the ex-tropical cyclone to the east coast near Cairns, which contain the storms that NASA's AIRS instrument saw.
ABM forecasts damaging winds, with gusts to 90 kph (56 mph) with showers and thunderstorms across Cape York Peninsula north of Cooktown. Locations which may be affected include Aurukun, Weipa, Torres Strait Islands, Lockhart River, Coen and Cooktown. Heavy rainfall is likely throughout the Peninsula district, coastal parts of the North Tropical Coast and Tablelands district, and coastal parts of the Herbert and Lower Burdekin district north of about Ayr. The heavy rainfall may also lead to flash flooding. For more information: http://www.bom.gov.au/cyclone/.
Forecasters expect Oswald to linger over the Cape York Peninsula and the Joint Typhoon Warning Center expects Oswald's remnants to continue tracking over land to the southeast.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
