Scientists explore radiation doses to airplane passengers from bursts of gamma-rays that originate from thunderclouds

Florida Institute of Technology faculty presented their terrestrial gamma ray flashes research modeling work at a press conference meeting of the European Geosciences Union in Vienna, Austria, April 10.

Nanotechnology: Color printing reaches new highs

Color printing at the highest resolution possible is enabled by the use of arrays of metal-coated nanostructures.

Simply changing the pattern by which data is recorded may lead to increased hard drive capacities, study finds

Modern hard drive technology is reaching its limits. Engineers have increased data-storage capacities by reducing the widths of the narrow tracks of magnetic material that record data inside a hard drive. Narrowing these tracks has required a concordant reduction in the size of the magnetic write head—the device used to create them. However, it is physically difficult to reduce the size of write heads any further.

Team improves the world's most accurate instrument for resistance measurement

Cryogenic Ltd and the National Physical Laboratory (NPL) have designed and developed the most accurate instrument for comparative measurements of electric current. The instrument can now be used by National Measurement Institutes (NMI) and laboratories around the world, providing a more accurate standard for current ratio, and ensuring current measurement is not a limiting factor in innovation.

Advancing secure communications: A better single-photon emitter for quantum cryptography

In a development that could make the advanced form of secure communications known as quantum cryptography more practical, researchers have demonstrated a simpler, more efficient single-photon emitter that can be made using traditional semiconductor processing techniques.

Watch This: The Year's Best Views of Earth From Space

T minus two weeks until Earth Day! In case you need one more reason to be amazed by the blue marble we live on, check out these views of Earth taken from space over the course of last year.

The video illustrates just how dynamic our planet can be, and doesn't need text or narration to deliver its message. From melting glaciers to fluctuations in salinity, NASA uses colorful time-lapse to show just how much our world changes in a single revolution of the sun. In certain shots, the surface of t

A step toward optical transistors?

Researchers have demonstrated a new way to control light in semiconductor nanocrystals.

A primary voltage standard for the whole world

( —PML researchers are on the verge of reaching a long-sought major goal: Providing the world with a programmable quantum voltage standard that has an uncertainty of less than 1 part per billion, never needs calibration, and is sufficiently automated that it can be used in developing countries by non-experts.
