Photo-monitoring whale sharks

Up to 20 meters long and weighing as much as 20 tons, its enormous size gives the whale shark its name. Listed as a rare species, relatively little is known about whale sharks. However, a new study combines computer-assisted photographic identification with ecotourism to study the rare species and suggests whale shark populations in Ningaloo, Western Australia are healthy. The study appears in...

Polarization technique focuses limelight

The ability to explore remote worlds in space has been enhanced through a polarization technique that allows the first ever detection of light reflected by extrasolar (exoplanet) planets. The study has been accepted for publication in Astrophysical Journal Letters.
