When Galaxies Eat Galaxies: Gravity Lenses Suggest Big Collisions Make Galaxies Denser
October 12, 2012 — Using gravitational "lenses" in space, astronomers have discovered that the centers of the biggest galaxies are growing denser -- evidence of repeated collisions and mergers by massive galaxies with ... > full story -
Fusion Energy: Mug Handles Could Help Hot Plasma Give Lower-Cost, Controllable Fusion Energy
October 11, 2012 — New hardware lets engineers maintain the plasma used in fusion reactors in an energy-efficient, stable manner, making the system potentially attractive for use in fusion power ... > full story -
Quantum Effects Observed in Cold Chemistry
October 11, 2012 — Physicists have combined two low-temperature supersonic beams to produce chemical reactions in quantum conditions, near absolute zero. The method, a first, confirms longstanding ... > full story -
Plasma Screens Enhanced as Disorder Strikes: Study Looks at Ways to Improve the Quality of Matter Akin to That Found in Plasma Screens
October 11, 2012 — A new study improves our understanding of plasma sources, a state of matter similar to gas in which a certain portion of the particles are ionised and which are used for example in plasma display ... > full story -
Nearby Super-Earth Likely a Diamond Planet
October 11, 2012 — New research suggests that a rocky planet twice Earth's size orbiting a nearby star is a diamond planet. The planet -- called 55 Cancri e -- has a radius twice Earth's, and a mass eight times ... > full story -
Graphene: A Patterned Template for Molecular Packing
October 11, 2012 — Simulations of atomic-scale processes show how to trap and pack molecules in patterned graphene sheets that may have molecular storage ... > full story -
Glaciers Cracking in the Presence of Carbon Dioxide
October 10, 2012 — The well-documented presence of excessive levels of carbon dioxide in our atmosphere is causing global temperatures to rise and glaciers and ice caps to melt. New research has shown that carbon ... > full story -
Sweeping X-Ray Imaging Survey of Dying Stars Is 'Uncharted Territory'
October 10, 2012 — The death throes of dying stars are the focus of a sweeping new survey using NASA's Chandra X-ray satellite observatory. More than two dozen astronomers have aligned their research goals to use ... > full story -
Surprising Spiral Structure Spotted by Astronomers
October 10, 2012 — Astronomers have discovered a surprising spiral structure in the gas around the red giant star R Sculptoris. This means that there is probably a previously unseen companion star orbiting the star. ... > full storyMore: -
Pioneer Anomaly Solved? Interstellar Travelers of the Future May Be Helped by Physicist's Calculations
October 9, 2012 — Interstellar travel will depend upon extremely precise measurements of every factor involved in the mission. The knowledge of those factors may be improved by a researcher's solution, found to a ... > full story
