Physicists working with the particle detector IceCube, buried near the South Pole, have detected neutrinos of high enough energies to suggest origins in the cataclysms at the Milky Way's fringes, or perhaps even past its doorstep.
Stephen Hawking says the next big physics discovery could be supersymmetry, the theory that subatomic particles have "superpartner" particles. Stephen Hawking lost a $100 bet that Higgs boson wouldn't be found.
Bioluminescent bay: The lagoon near Fajardo, Puerto Rico glows when microscopic organisms in the water are disturbed. The bioluminescent lagoon has been dark for at least eight days, says the mayor of Fajardo.
Granite isn't just for countertops anymore. Though common on Earth, granite on Mars has eluded scientists for years, because the key ingredients, quartz and feldspar, are nearly impossible to detect from satellites in orbit.
A dog trained to detect polar bear pregnancies, long a difficult task for conservationists hoping to breed the threatened species, has sniffed fecal samples from female polar bears in zoos all around the US.
