Entangled Photons Make Better Messengers
from ScienceNews
To send a quantum message, it helps to have a photon six-pack. When bound together by a process called quantum entanglement, a set of six photons can withstand the hard knocks that ordinarily would erase quantum information, researchers have shown. Full Article
Crystal is One-way Street for Microwaves
from NewScientist
It is like a valve for light - the first material that transmits electromagnetic radiation in one direction only. Zheng Wang and colleagues at the Massachusetts Institute of Technology have made what's known as a photonic crystal from an array of ferrite rods. Full Article
Gravity-Mapping Satellite to Help Predict Climate
from Discovery News
Nearly seven months after hitting orbit, the European Space Agency (ESA)'s latest super satellite has begun its heady task of measuring true gravity on Earth. Full Article
Big Bang Flashgun to Snap Atomic Anatomy
from NewScientist
A strange state of matter that dominated the early universe could be used to create ultra-fast flashes of radiation, brief enough to capture what's going on inside atomic nuclei. Full Article

Introducing the Most Efficient Solar Power in the World
from Discover Magazine
A new solar thermal system being developed at the Sandia National Laboratory's National Solar Thermal Test Facility achieves record setting efficiency, while another offers inexpensive, robust power and plentiful hot water for people in developing countries. Full Article
Research in a Vacuum: DARPA Tries to Tap Elusive Casmir Effect for Breakthrough Technology
from Scientific American
Named for a Dutch physicist, the Casimir effect governs interactions of matter with the energy that is present in a vacuum. Success in harnessing this force could someday help researchers develop low-friction ballistics and even levitating objects that defy gravity. For now, the U.S. Defense Department's Defense Advanced Research Projects Agency (DARPA) has launched a two-year, $10-million project encouraging scientists to work on ways to manipulate this quirk of quantum electrodynamics.

Researchers have demonstrated a penny-sized "nuclear battery" that produces energy from the decay of radioisotopes. Full Article
Physics? It's All the Same to Birds and Babies
from ScienceNOW
Even with their tiny bird brains, rooks comprehend basic principles of physics at the same level as a 6-month-old baby—and beyond that of chimpanzees—a new study reports. But whether this understanding conveys any advantages remains an open question. Full Article
