A combined image created from infrared data obtained by the Atmospheric Infrared Sounder (AIRS) instrument that flies on NASA's Aqua satellite provides a comparison of the two monster storms in the western North Pacific Ocean basin.
This combined image was created from infrared AIRS data of Super Typhoon Jelawat on Sept. 25 and Tropical Storm Ewiniar on Sept. 24 to give perspective of their distance from each other. The eye of Jelawat is clearly visible in the middle of powerful thunderstorms (purple) with very cold cloud top temperatures. Credit: NASA JPL/Ed Olsen
An infrared image of Typhoon Jelawat captured on Sept. 25 was combined with an image of Tropical Storm Ewiniar, that was taken on Sept. 24. The combined image gives perspective of the distance of the tropical cyclones from each other. The image showed the close proximity of the storms. Earlier in the week, Jelawat's outflow was affecting Ewiniar and preventing it from strengthening more quickly.
The data also showed a visible eye in the center of super typhoon Jelawat in the middle of powerful thunderstorms with very cold cloud top temperatures that exceed -63 Fahrenheit (-52 Celsius). Jelawat also has a rounded shape indicating that circulation is strong and symmetrical. Tropical Storm Ewiniar, however, appears somewhat asymmetrical, in the form of an elongated comma shape. The comma's "tail" is a large band of strong thunderstorms wrapping into Ewiniar's center from the southeast.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured a natural-color image on September 24, 2012, showing Jelawat just east of the Philippines. Sporting a distinct eye and spiral arms characteristic of strong storms, Jelawat spanned hundreds of kilometers (miles). As of September 24, 2012, the Joint Typhoon Warning Center (JTWC) classified Jelawat as a super typhoon. For the MODIS image, visit: http://lance-modis.eosdis.nasa.gov/cgi-bin/imagery/single.cgi?image=Jelawat.A2012268.0430.2km.jpg.
Jelawat remains a super typhoon today, Sept. 25, with maximum sustained winds near 140 knots (161 mph/259 kmh). It is located 385 nautical miles east-northeast of Manila, Philippines, and is moving north-northwestward at 6 knots (7 mph/11 kmh). Satellite imagery is showing tightly wrapped bands of thunderstorms spiraling into the eye of the storm. The eye is about 17 nautical miles wide. High pressure in the upper atmosphere and low wind shear are helping the super typhoon maintain its intensity. The JTWC projected storm track showed the storm moving toward the north-northwest over the next several days, passing near the island of Taiwan before turning toward the northeast.Text credit: Rob Gutro

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
