The TRMM satellite saw tropical storm Ernesto on August 9, 2012 at 0656 UTC (2:36 a.m. EDT) after it moved from the Yucatan Peninsula into the Gulf of Mexico. An analysis of TRMM Microwave Imager (TMI) and Precipitation Radar (PR) rainfall shows that powerful convective thunderstorms were dropping rain at a rate greater than 50mm per hour (~2 inches) north of the storm's center.

TRMM Precipitation Radar (PR) data were used to create a 3-D view of Ernesto's vertical structure. The PR view shows that a few of the powerful convective storms near Ernesto's center were pushing to heights of over 16 kilometers (~9.94 miles). The energy released by these storms near Ernesto's center can be a sign of intensification.
At 10 a.m. EDT on August 9, the National Hurricane Center noted that Ernesto's center was located very close to the coast, or already on land, near 18.2 North and 94.3 West. Ernesto's maximum sustained winds are near 60 mph (95 kmh) with higher gusts, but as Ernesto moves inland it is expected to weaken. Ernesto is moving west near 10 mph (17 kmh) and will move over southern Mexico over the next two days.
A Tropical Storm Warning is in effect from Veracruz to Chilitepec today, August 9. The National Hurricane Center expects the heavy rainfall that NASA's TRMM satellite identified to bring between five to 10 inches of rain, locally up to 15 inches, over the Mexican states of Tabasco, Veracruz, Puebla and Oaxaca. Flash floods and mudslides are a concern with these large amounts of rainfall. In addition another one to two inches of rain are possible over northern Guatemala and the southwestern Yucatan Peninsula.
A visible image of Tropical Storm Ernesto was captured from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra satellite, on August 8, when it was over the Yucatan Peninsula, and before it emerged into the Gulf of Mexico.

Frictional Heat Powers Hydrothermal Activity on Enceladus

Heat from the friction of rocks caused by tidal forces could be the “engine” for the hydrothermal activity on Saturn's moon Enceladus. This presupposes that...
The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
