Magnetic Forces Without Magnets: Physicist Calculates Field Strengths in the Early Universe
January 2, 2013 — Magnets have practically become everyday objects. Earlier on, however, the universe consisted only of nonmagnetic elements and particles. Just how the magnetic forces came into existence has now been ... > full story -
Space Travel May Be Harmful to the Brain, Study Suggests; Prolonged Cosmic Radiation Exposure Could Hasten Alzheimer's
December 31, 2012 — As if space travel was not already filled with enough dangers, a new study shows that cosmic radiation -- which would bombard astronauts on deep space missions to places like Mars -- could accelerate ... > full story -
An Image Gallery Gift from NASA's Swift
December 28, 2012 — Of the three telescopes carried by NASA's Swift satellite, only one captures cosmic light at energies similar to those seen by the human eye. Although small by the standards of ground-based ... > full story -
Measurements Hint Why the Universe Is Dominated by Matter, Not Anti-Matter
December 26, 2012 — Physicists have made a precise measurement of elusive, nearly massless particles, and obtained a crucial hint as to why the universe is dominated by matter, not by its close relative, ... > full story -
Canadian Experiment to Track Space Radiation and Its Risks
December 20, 2012 — Space can be a potentially hazardous environment to live and work in, especially when it comes to radiation. Originating from violent storms on the Sun and galactic cosmic rays produced in distant ... > full story -
Science's Breakthrough of the Year: Discovery of the Higgs Boson

Long-Wavelength Laser Will Take Better 'Fingerprints' of Medicines Than Chemical Analysis, Research Suggests
December 19, 2012 — A laser capable of working in the terahertz range – that of long-wavelength light from the far infrared to 1 millimeter – takes a better 'fingerprint' of, say, a drug under investigation, ... > full story -
Prehistoric Ghosts Revealing New Details: Synchrotron Helps Identify Previously Unseen Anatomy Preserved in Fossils
December 18, 2012 — Scientists have used synchrotron-based imaging techniques to identify previously unseen anatomy preserved in fossils. Their work on a 50-million-year-old lizard skin identified the presence of ... > full story -
Scientists Developing Quick Way to ID People Exposed to Ionizing Radiation
December 17, 2012 — A new study could lead to a blood test that detects if a person has been exposed to radiation, measures their dose, and separates people suffering from inflammation injuries -- all in a matter of ... > full story -
How White Dwarfs Mimic Black Holes
December 17, 2012 — Astronomers have revealed that bright X-ray flares in nearby galaxies, once assumed to indicate the presence of black holes, can in fact be produced by white dwarfs. They made the discovery by ... > full story
