Microbial detection array detects plague in ancient human remains
(Phys.org) —Scientists who study past pandemics, such as the 14th century Black Death that devastated much of Europe, might soon be turning to an innovative biological detection technology for some extra ...
Transparent, color solar cells fuse energy, beauty
(Phys.org) —Colorful, see-through solar cells invented at the University of Michigan could one day be used to make stained-glass windows, decorations and even shades that turn the sun's energy into electricity.
Fine-tuning a rainbow of colors at the nanoscale
(Phys.org) —TVs, image sensors, iPads, digital cameras and other modern devices use filters to display the breadth of colors available in the visible portion of the electromagnetic spectrum.
'Superlens' extends range of wireless power transfer
(Phys.org) —Inventor Nikola Tesla imagined the technology to transmit energy through thin air almost a century ago, but experimental attempts at the feat have so far resulted in cumbersome devices that ...
Researchers discover roots of superfluorescent bursts from quantum wells
Spontaneous bursts of light from a solid block illuminate the unusual way interacting quantum particles behave when they are driven far from equilibrium. The discovery by Rice University scientists of a way ...
Infrared vision lets researchers see through—and into—multiple layers of graphene
(Phys.org) —It's not X-ray vision, but you could call it infrared vision.
Scientists unveil energy-generating window
Scientists in China said Thursday they had designed a "smart" window that can both save and generate energy, and may ultimately reduce heating and cooling costs for buildings.
