Ricoh Launches Pentax KP Weatherproof DSLR With Extreme Low-Light Shooting Capability

  Ricoh Imaging has launched the Pentax KP, a compact and portable APS-DSLR, designed specifically for night photography. The camera will go on sale from February 25 for $1,100 (approximately Rs. 74,800). The highlight feature here is the very high sensitivity of the sensor which goes all the way up to ISO 819200, which should make it possible to capture images in next to no light. The Pentax KP features a 24-megapixel APS-C sensor with a 27-point autofocus system and is the first Pentax APS-C camera to have the Shake…

Scientists Create Metallic Hydrogen, a Possible Superconductor, Ending Quest

US scientists have succeeded in squeezing hydrogen so intensely that it has turned into a metal, creating an entirely new material that might be used as a highly efficient electricity conductor at room temperatures. The discovery, published in the journal Science on Thursday, provides the first confirmation of a theory proposed in 1935 by physicists Hillard Bell Huntington and Eugene Wigner that hydrogen, normally a gas, could occur in a metallic state if exposed to extreme pressure. Several teams have been racing to develop metallic hydrogen, which is highly prized…
