Multi-Object Double Spectrograph Reveals Likely Origins of Bright Supernovae

A study using a unique new instrument on the world's largest optical telescope has revealed the likely origins of especially bright supernovae that astronomers use as easy-to-spot "mile markers" to measure the expansion and acceleration of the universe.

Study Reveals Preferred Direction of Time's Quantum Arrow

Time marches relentlessly forward for you and me; watch a movie in reverse, and you'll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse – a concept known as time reversal symmetry.

Large Underground Xenon Experiment to Look for Dark Matter is Now Underwater

An experiment to look for one of nature's most elusive subatomic particles is finally underwater, in a stainless steel tank nearly a mile underground beneath the Black Hills of South Dakota. And among the dozens of scientists involved in the research collaboration is the University of Rochester's Professor Frank Wolfs.

Geophysicists Study Esquel Meteorite with Superconducting Quantum Interference Device

A tiny fraction of meteorites on earth contain strikingly beautiful, translucent, olive-green crystals embedded in an iron-nickel matrix. Called pallasites, these "space gems" have fascinated scientists since they were first identified as originating from outer space more than 200 years ago.
