NASA sees Typhoon Saola's huge reach over the Philippines

Typhoon Saola looks like a monster tropical cyclone in infrared imagery from NASA's Aqua satellite today, July 30. Although Saola's center is over 300 nautical miles (368 miles/592 km) south-southeast of Taiwan, it stretches ...

Portable device detects soil contamination

(Phys.org) -- The RemScan device uses an infrared signal to directly measure petroleum hydrocarbons in soil. The user simply pulls the trigger for a result in 15 seconds. The traditional method for measuring petroleum contamination ...

Tropical Depression Dokuri weaker, but still potent

Tropical Storm Dokuri weakened into a tropical depression today, but NASA infrared satellite imagery is still showing some areas of strong convection and thunderstorms in the storm and they're being pushed away from the center.

A smarter way to make ultraviolet light beams

Existing coherent ultraviolet light sources are power hungry, bulky and expensive. University of Michigan researchers have found a better way to build compact ultraviolet sources with low power consumption that could improve ...

'Microring' device could aid in future optical technologies

(PhysOrg.com) -- Researchers at Purdue University and the National Institute of Standards and Technology (NIST) have created a device small enough to fit on a computer chip that converts continuous laser light into numerous ...

Graphene may open the gate to future terahertz technologies

Nestled between radio waves and infrared light is the terahertz (THz) portion of the electromagnetic spectrum. By adding a nanoscale bit of graphene, researchers have found a better way to tune radiation for a THz transmitter.

NASA satellite shows a mean Irene's fury

(PhysOrg.com) -- After pounding North Carolina and Virginia on Aug. 27, Hurricane Irene made a second landfall near Little Egg Inlet, N.J., early Sunday morning, Aug. 28, still as a category one hurricane with maximum sustained ...
