Cyclone Laila, Formerly Tropical Storm 1B, is Headed for Landfall in India

Tropical Storm 1B strengthened overnight into a Category One cyclone on the Saffir-Simpson scale and has been officially renamed "Laila." NASA's Aqua satellite captured a visible image of Laila today, May 19, revealing that the storm has organized overnight and is already affecting coastal areas of southern India.

The Moderate Resolution Imaging Spectroradiomenter or MODIS instrument that flies aboard Aqua captured Laila in an image at 08:10 UTC (4:10 a.m. EDT). At that time, Laila had reached cyclone strength with maximum sustained winds near 74 mph. It was located about 70 nautical miles east-northeast of Chennai, India, near 13.9 North latitude and 91.3 East longitude. Laila is moving northwestward near 7 mph (6 knots).

The Atmospheric Infrared Sounder (AIRS) instrument that also flies aboard NASA's Aqua satellite captured an infrared image of the cloud-top temperatures in Laila at the same time. The image showed that the higher, colder, more powerful thunderstorms were still over the Bay of Bengal and mostly in the eastern half of the storm. In addition, there were some high, strong thunderstorms over land.

Forecasters at the India Meteorological Department noted in an advisory on May 19, "the system is likely to intensify further and move in a northwesterly to northerly direction and cross Andhra Pradesh Coast between Nellore and Kakinada, close to Machilipatnam by morning of may 20." For updates on Watches and Warnings along the India coast, visit the India Meteorological Department's web site at:

The Joint Typhoon Warning Center, the organization that forecasts for tropical cyclones in the Northern Indian Ocean, noted that Cyclone Laila is expected to make landfall near 2 p.m. EDT on Thursday and gradually weaken as it tracks along the southeast coast of India. Its track will take it toward Bangladesh and over the northern Bay of Bengal by Saturday, May 22.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
