Satellite imagery shows two lows in the Atlantic as Tropical Storm Hector spins in the Eastern Pacific Ocean with System 95E near the Mexican coast.
This image of the Atlantic Ocean and eastern Pacific Ocean was created by NASA's GOES Project using NOAA GOES-13 and GOES-15 satellite imagery on Aug. 13, 2012 at 7:45 a.m. EDT. The remnants of Tropical Depression 7 in the Caribbean Sea, and the low pressure area called System 93L in the eastern Atlantic. In the eastern Pacific, Tropical Storm Hector looks disorganized and System 95E is near the Mexican coast.

The NOAA GOES-13 satellite sits in a fixed orbit over the eastern U.S. and provides infrared and visible imagery of the Atlantic Ocean basin continuously. At the same time, NOAA's GOES-15 satellite covers the western U.S. and eastern Pacific Ocean. At NASA's GOES Project, the data from the satellites were combined to create a "full-disk view" of the Atlantic and eastern Pacific Ocean. NASA's GOES Project is located at NASA's Goddard Space Flight Center, Greenbelt, Md., and creates images and animations from the two GOES satellites.
A visible and infrared image of the Atlantic Ocean and eastern Pacific Ocean were combined to give a complete picture of the tropics on both sides of the continental U.S. on August 13, 2012 at 7:45 a.m. EDT.
Tropical Depression 7 and System 93L
The GOES-13 part of the image, which is in visible light, shows two areas of disturbances in the tropics. The remnants of Tropical Depression 7 in the Caribbean Sea, and the low pressure area called System 93L in the eastern Atlantic.
Tropical Depression 7 (TD7) weakened to a remnant low pressure area on Saturday, August 11 at 11 a.m. EDT. It brought squalls of wind and rain to the Lesser Antilles over the weekend. On Monday, August 13, the remnants were moving over the central Caribbean Sea and are producing disorganized showers and thunderstorms extending from the central Caribbean northward to Hispaniola. The National Hurricane Center noted that "environmental conditions are not expected to be conducive for regeneration, and this system has a low chance, 10 percent, of becoming a tropical cyclone again during the next 48 hours as it moves westward near 20 mph." In the GOES-13 imagery from August 13, TD7's remnants appear elongated, which is likely from wind shear.
The low pressure area called System 93L ran into adverse atmospheric conditions over the weekend of August 11-12, 2012, but conditions are expected to improve over the next couple of days. The National Hurricane Center (NHC) noted that "Shower activity remains limited in association with a broad area of low pressure located about 1,200 miles west-northwest of the Cape Verde Islands." The NHC gives System 93L just a ten percent chance of organizing over the next two days into a tropical depression. Meanwhile, System 93L continues to move west-northwestward at around 20 mph.
Eastern Pacific's Tropical Storm Hector and System 95E
The Atlantic Ocean's Tropical Storm Ernesto changed names. Ernesto crossed Mexico from the Gulf of Mexico to the eastern Pacific as a remnant low pressure system. On Saturday, August 11 at 1 p.m. EDT, the low re-strengthened into tropical depression 8E. At that time, Tropical Depression 8E was located about 150 miles (245 km) southwest of Manzanillo, Mexico, near 17.5 North and 106.0 West. Twelve hours later at 11 p.m. EDT, the depression strengthened into Tropical Storm Hector becoming the eighth tropical storm of the season.
By 5 a.m. EDT on August 13, Hector's maximum sustained winds decreased to near 40 mph (65 kmh). Hector was located near latitude 18.1 north and longitude 111.4 west, about 55 miles (90 km) west of Sorocco Island. Hector is moving west at 7 mph (11 kmh) and is expected to turn to the west-northwest and slow over the next couple of days. Wind shear appears to be taking its toll on Hector as it appears somewhat elongated in the GOES-15 satellite image from August 13. Wind shear is expected to remain strong over the next couple of days, which should keep Hector from strengthening and may weaken it to a remnant low pressure area.
A weak area of low pressure called System 95E is located about 175 miles southeast of Acapulco, Mexico continues to produce showers and thunderstorms. System 95E appears to have a tight circulation on the GOES-15 satellite imagery on August 13. The NHC gives System 95E a 20 percent chance of becoming a tropical depression in the next couple of days, while it moves to the west-northwest at 10 mph.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
