Greg grew into a hurricane today is it continues moving near the western coast of Mexico, while Fernanda has maintained tropical storm strength.

The Geostationary Operational Environmental Satellite called GOES-11 caught an image of eastern Pacific on August 18 at 1200 UTC (8 a.m. EDT) saw Tropical Storm Fernanda approaching the central Pacific Ocean and Hurricane Greg behind her in the eastern Pacific Ocean. The image was created at NASA's GOES Project, located at NASA Goddard Space Flight Center in Greenbelt, Md. NOAA manages the GOES-11 satellite and NASA uses its data to create images and animations.At 11 a.m. EDT (5 a.m. Hawaii Standard Time) Fernanda's maximum sustained winds were near 65 mph, just 9 mph shy of hurricane status. She was located about 1040 miles east-southeast of South Point, Hawaii near latitude 13.7 North and longitude 141.0 West. Fernanda is moving toward the west-northwest near 13 mph and is expected to take a more westerly track in the next 48 hours after which she's expected to weaken because of adverse atmospheric conditions.
That strength isn't expected to hold for the next 48 hours, though. The National Hurricane Center noted "by the time Fernanda passes south of the main Hawaiian Islands it is expected to have weakened to a remnant low."
Fernanda and Greg are now about the same size. Fernanda's tropical storm-force winds extend outward up to 80 miles from the center. Greg's tropical storm-force winds extend to about 85 miles from the center, while his hurricane-force winds extend 25 miles out.
At 11 a.m. EDT (8 a.m. PDT) Greg's maximum sustained winds were near 85 mph, making him a category one hurricane on the Saffir-Simpson Scale. He was moving to the west-northwest near 18 mph and is forecast to move in a more westerly direction in the next couple of days.
Greg was centered about 320 miles south-southwest of the southern tip of Baja California near 18.5 North and 111.5 West and was passing Mexico's Socorro Island. The automated weather station on the island reported sustained winds of 38 mph and a wind gust of 53 mph.
NASA's Tropical Rainfall Measuring Mission (TRMM) satellite saw Greg as a tropical storm on August 17 at 0534 UTC. At that time, TRMM's Microwave Imager showed that intense convective thunderstorms within the developing storm were dropping rainfall at rates greater than 30mm/hr (1.2 inches) in an area near the center of the storm. Greg's rainfall rates have increased as he strengthened into a hurricane. Greg is forecast to move into cooler waters in three days, at which time he will begin to weaken. In the meantime, he continues to chase Fernanda through the Eastern Pacific Ocean.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
