Researchers discover new way to turn electricity into light, using graphene

By slowing down light to a speed slower than flowing electrons, researchers create a kind of optical "sonic boom"

Light-matter interplay probed: Physicists achieve quantum Hall state with light

Harnessing the shared wave nature of light and matter, researchers have used light to explore some of the most intriguing questions in the quantum mechanics of materials.

Meta-lens works in the visible spectrum, sees smaller than a wavelength of light

High efficiency ultra-thin planar lens could replace heavy, bulky lenses in smart phones, cameras and telescopes.

Bionic leaf turns sunlight into liquid fuel: New system surpasses efficiency of photosynthesis

Scientists have created a system that uses solar energy to split water molecules and hydrogen-eating bacteria to produce liquid fuels. The system can convert solar energy to biomass with 10 percent efficiency, far above the 1 percent seen in the fastest-growing plants.

Five ways to travel through time

Travel to the past is probably impossible. But the future is a different story.

Newly discovered form of spiralized light breaks everything quantum physics says about photons

Scientists in Ireland discovered a new form of light that will radically change our understanding of how light functions.

From IT to black holes: Nano-control of light pioneers new paths

Breakthrough chip for nano-manipulation of light paves way for next generation optical technologies and enables deeper understanding of black holes

Astronomers report most 'outrageously' luminous galaxies ever observed

Astronomers report that they have observed the most luminous galaxies ever seen in the Universe, objects so bright that established descriptors such as 'ultra-' and 'hyper-luminous' used to describe previously brightest known galaxies don't even come close.

Discovery of two close-in exoplanet companions sheds new light on planet formation

Some 300 hot Jupiters have been identified over the past two decades, and this is the first time any close-in planets were discovered.

Black hole caught SHREDDING a star 'just' 290 million light years away

Astronomers at the University of Maryland, observed the event, which is the closest tidal disruption discovered in about a decade.

Scientists drag light by slowing it to speed of sound

(PhysOrg.com) -- Scientists at the University of Glasgow have, for the first time, been able to drag light by slowing it down to the speed of sound and sending it through a rotating crystal.
