Galactic Spin Underlies Matter/Antimatter Decay Asymmetry
According to the conclusions of a new study, it would appear that the gigantic mass our galaxy has may contribute to underlying the asymmetry in decay rates between matter and antimatter. This phenomenon, called charge-parity (C-P) violation, has remained mysterious for years. The Milky Way has a tremendously large mass, accounted for by both normal, […]
Yeast Rising to the Space Station
July 15, 2011
Chefs across the globe may not know it yet, but their baker’s yeast just left the kitchen and blasted off into low Earth orbit. Hitching a ride on the space shuttle Atlantis on July 8, 2011, the samples will be grown on the International Space Station as part of the Genotypic and Phenotypic Changes in […]
Dark-energy fingerprints found in ancient radiation
July 15, 2011
Only cat burglars can match the stealth of dark energy, credited with speeding up the universe’s expansion over time, but now its fingerprints have been glimpsed in the universe’s oldest radiation. The strongest evidence for dark energy comes from supernovae, which suggest the universe is expanding faster now than in the past. But the force should also change […]
Quantum quirk makes carbon dating possible
July 15, 2011
RADIOCARBON dating relies on carbon-14 to decode an object’s age, but the isotope has steadfastly refused to divulge the key to its own unusual longevity. The answer, it seems, lies in the bizarre rules of quantum physics. Carbon-14 decays with a half-life of 5730 years, so it is often used to date objects up to about 50,000 […]
My favourite particle: the neutron
July 15, 2011
A guest post by Jim Grozier on particles you can store in a beryllium bottle without a lid on I’m not really one for favourites, but I do have a soft spot for the neutron; and after all, it would be a shame to leave it out, wouldn’t it? There are two things I really […]
