A new antenna made of plasma (a gas heated to the point that the electrons are ripped free of atoms and molecules) works just like conventional metal antennas, except that it vanishes when you turn…

The big world of classical physics mostly seems sensible: waves are waves and particles are particles, and the moon rises whether anyone watches or not. The tiny quantum world is different: particles…

An Israeli-Jordanian-U.S. cooperative project aimed at measuring air quality in the area between the neighboring southern cities of Aqaba in Jordan and Eilat in Israel has been launched by scientists…

Rutgers University physicists have performed computer simulations that show how electrons become one thousand times more massive in certain metal compounds when cooled to temperatures near absolute…

The running joke in science has always been that the metric system was invented by the French to combat English predominance culturally - and they got the measurement wrong. Still, it caught on (…

For almost 75 years, astronomers have believed that the Universe has a large amount of unseen or ‘dark’ matter, thought to make up about five-sixths of the matter in the cosmos. With the conventional…

Sandia National Laboratories’ Z machine, the world’s largest producer of X-rays, shook the ground for several hundred yards in every direction for the first time since July 2006, when the 22-year-old…

A transistor containing quantum dots that can count individual photons (the smallest particles of light) has been designed and demonstrated at the National Institute of Standards and Technology (NIST…

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2007 jointly to Albert Fert, Unité Mixte de Physique CNRS/THALES, Université Paris-Sud, Orsay, France, and…

Quantum dots have great promise as light-emitting materials, because the wavelength, or color, of light that the quantum dots give off can be very widely tuned simply by changing the size of the…
