Thermal vision: Graphene light detector first to span infrared spectrum
The first room-temperature light detector that can sense the full infrared spectrum has the potential to put heat vision technology into a contact lens.
Physicists propose a device to capture energy from Earth's infrared emissions to outer space
(Phys.org) —When the sun sets on a remote desert outpost and solar panels shut down, what energy source will provide power through the night? A battery, perhaps, or an old diesel generator? Perhaps something ...
Star is discovered to be a close neighbor of the Sun and the coldest of its kind
(Phys.org) —A "brown dwarf" star that appears to be the coldest of its kind—as frosty as Earth's North Pole—has been discovered by a Penn State University astronomer using NASA's Wide-field Infrared ...
Bending the light with a tiny chip
(Phys.org) —Imagine that you are in a meeting with coworkers or at a gathering of friends. You pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your ...
Mystery of planet-forming disks explained by magnetism
(Phys.org) —Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006.
Making silicon devices responsive to infrared light
Researchers have tried a variety of methods to develop detectors that are responsive to a broad range of infrared light—which could form imaging arrays for security systems, or solar cells that harness ...
In distance space, a water world: Hubble reveals a new class of extrasolar planet
(PhysOrg.com) -- An international team of astronomers led by Zachory Berta of the Harvard-Smithsonian Center for Astrophysics (CfA) made the observations of the planet GJ 1214b.
Pitch black: Cosmic clumps cast the darkest shadows
(Phys.org) —Astronomers have found cosmic clumps so dark, dense and dusty that they throw the deepest shadows ever recorded. Infrared observations from NASA's Spitzer Space Telescope of these blackest-of-black ...
Engineering light-controlled proteins
(Phys.org) —A University of Wyoming professor has engineered proteins that can be activated by near-infrared light as a way to control biological activities in deep tissues of small mammals.
Polymer microparticles could help verify goods
Some 2 to 5 percent of all international trade involves counterfeit goods, according to a 2013 United Nations report. These illicit products—which include electronics, automotive and aircraft parts, pharmaceuticals, ...
Scientists create highly transparent solar cells for windows that generate electricity
(Phys.org) -- UCLA researchers have developed a new transparent solar cell that is an advance toward giving windows in homes and other buildings the ability to generate electricity while still allowing people ...
Spitzer sees the light of alien 'super earth'
(Phys.org) -- NASA's Spitzer Space Telescope has detected light emanating from a "super-Earth" planet beyond our solar system for the first time. While the planet is not habitable, the detection is a historic ...
Researchers devise means to combine scanning tunneling microscopy and infrared spectroscopy
Curiosity rover's laser instrument zaps first martian rock
(Phys.org) -- Today, NASA's Mars rover Curiosity fired its laser for the first time on Mars, using the beam from a science instrument to interrogate a fist-size rock called "Coronation."
