Thin Photodetector Increases Performance Without Adding Bulk

In today’s increasingly powerful electronics, tiny materials are a must as manufacturers seek to increase performance without adding bulk. Smaller also is better for optoelectronic devices — like camera sensors or solar cells — which collect light and convert it to electrical energy. Think, for example, about reducing the size and weight of a series of solar panels, producing a higher-quality photo in low lighting conditions, or even transmitting data more quickly.

Single-Photon Emitter Holds Promise for Quantum Info-Processing

Los Alamos National Laboratory has produced the first known material capable of single-photon emission at room temperature and at telecommunications wavelengths. These carbon nanotube quantum light emitters may be important for optically-based quantum information processing and information security, while also being of significant interest for ultrasensitive sensing, metrology and imaging needs and as photon sources for fundamental advances in quantum optics studies.

A Balancing Act: How Months in Space Impact Astronauts' Performance

When you arrive back on Earth after a year in space, you’re going to feel it.

NASA and Jacob Bloomberg, senior scientist in the Houston, TX- headquartered Johnson Space Center, have been trying to quantify exactly what those effects will be — and how 12 months of microgravity impact an astronaut’s ability to perform simple operational tasks like opening a hatch or climbing a ladder.
