The Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite captured an infrared image of Cyclone Gino on Feb. 12 at 1935 UTC (2:35 p.m. EST).
On Feb. 13 at 0505 UTC (12:05 a.m. EST) the MODIS instrument aboard NASA's Terra satellite captured this visible image of Tropical Cyclone Gino in the Indian Ocean. This close-up image clearly shows the ocean surface in the middle of Gino's eye. Credit: NASA Goddard MODIS Rapid Response Team
The AIRS temperature data showed Gino maintained a large area of powerful thunderstorms with cold cloud top temperatures and a band of strong thunderstorms wrapping in from the southeast. Cloud top temperatures in both of those areas were as cold as -63 Fahrenheit (-52 Celsius), and are an indication of heavy rainfall. AIRS data during the early morning hours of Feb. 13 indicated cloud top temperatures have warmed slightly, and convection around Gino's center has weakened a little.
At 0505 UTC (12:05 a.m. EST) on Feb. 13 the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA's Terra satellite captured a visible image of Gino. The image clearly showed the ocean surface down through the middle of Gino's ragged eye. According to the Joint Typhoon Warning Center, microwave satellite imagery indicated that the eye is weakening on both low- and mid-levels.
By 1200 UTC (7 a.m. EST), Gino's maximum sustained winds were as high as 85 knots (97.8 mph/157.4 kph) making the storm a Category 2 hurricane on the Saffir-Simpson scale. Gino was centered near 20.6 south latitude and 79.9 east longitude, about 875 nautical miles (1,007 miles/ 1,621 km) south-southeast of Diego Garcia, and far from any land areas. Gino was moving to the south-southeast at 11 knots (12.6 mph/20.3 kph).
Gino continues to head into cooler sea surface temperatures. An approaching trough, or elongated area of low pressure is expected to increase wind shear. Those two factors will adversely affect Gino over the next couple of days.Text Credit: Rob Gutro

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
