Study says nocturnal ants have evolved night vision
(PhysOrg.com) -- Researchers studying the eyes of different Australian bull ants have found the first evidence of adaptation of visual structures within a single species to distinct light intensities.
Artificial photosynthesis to make plants green with envy
Natural photosynthesis—the remarkable ability of plants to transform sunlight into useful energy—powers virtually all life on Earth. But that's not enough for some people.
Cantilever bends repeatedly under light exposure for continuous energy generation
Li-Fi: Edinburgh prof seeds LEDs for communication
'Super atoms': Rydberg excitations form ordered structures in a quantum gas due to long-range interactions
(Phys.org)—Future computers are expected to use the laws of quantum physics to accomplish certain tasks in the blink of an eye that require decades for present-day computers. Physicists at the Max Planck ...
Extraordinary light enhancement technique proposed for nanophotonic devices
Chandra finds nearest pair of supermassive black holes
(PhysOrg.com) -- Astronomers have used NASA's Chandra X-ray Observatory to discover the first pair of supermassive black holes in a spiral galaxy similar to the Milky Way. At a distance of 160 million light ...
Nano antenna concentrates light: Intensity increases 1,000-fold
(PhysOrg.com) -- Everybody who's ever used a TV, radio or cell phone knows what an antenna does: It captures the aerial signals that make those devices practical. A lab at Rice University has built an antenna ...
Suspects in the quenching of star formation exonerated
Supermassive black holes millions to billions times the mass of our Sun lie at the heart of most, maybe all large galaxies. Some of these power brilliantly luminous, rapidly growing objects called active galactic nuclei that ...
A nanotech solution controlling the path of light can brighten up our lives
We want our electrical devices to have bright screens with low energy needs, so they can be used for a long time before recharge is required. Scientists are increasing the intensity of light by making nanometer ...
Researchers glimpse the inside of a photonic crystal
Astronomers measure nearby Universe's 'cosmic fog'
Researchers from the Laboratoire Leprince-Ringuet (CNRS/École Polytechnique) have carried out the first measurement of the intensity of the diffuse extragalactic background light in the nearby Universe, ...
Tabletop laser-like device creates coherent multicolor beams of ultraviolet, T- and X-rays
For the first time, researchers have produced a coherent, laser-like, directed beam of light that simultaneously streams ultraviolet light, X-rays, and all wavelengths in between.
Tying the knot with computer-generated holograms: Winding optical path moves matter
In the latest twist on optical knots, New York University physicists have discovered a new method to create extended and knotted optical traps in three dimensions. This method, which the NYU scientists describe ...
