Engineers use disorder to control light on a nanoscale
A breakthrough by a team of researchers from UCLA, Columbia University and other institutions could lead to the more precise transfer of information in computer chips, as well as new types of optical materials ...
Wild molecular interactions in a new hydrogen mixture
Hydrogen—the most abundant element in the cosmos—responds to extremes of pressure and temperature differently. Under ambient conditions hydrogen is a gaseous two-atom molecule. As confinement pressure ...
Berkeley team explores sound for indoor localization
New system allows for high-accuracy, through-wall, 3-D motion tracking (w/ Video)
Imagine playing a video game like Call of Duty or Battlefield and having the ability to lead your virtual army unit while moving freely throughout your house.
MIT team shows system that tracks people through walls
Four microphones, computer algorithm enough to produce 3-D model of simple, convex room
Blind people sometimes develop the amazing ability to perceive the contours of the room they're in based only on auditory information. Bats and dolphins use the same echolocation technique for navigating ...
'Land grabbing' could help feed at least 300 million people, study suggests
Crops grown on "land-grabbed" areas in developing countries could have the potential to feed an extra 100 million people worldwide, a new study has shown.
Straw albedo mitigates extreme heat
Wheat fields are often tilled immediately after the crop is harvested, removing the light-coloured stubble and crop residues from the soil surface and bringing dark bare earth to the top. Post-harvest tilling ...
Researchers develop a system that creates personalized climates around individuals
MIT researchers have developed a system that creates personalized climates around individuals. The project, called "Local Warming," uses WiFi-based motion tracking and ceiling-mounted dynamic heating elements ...
Conflict with communities a big cost to business, researchers find
(Phys.org) —Researchers at The University of Queensland (UQ), the Harvard Kennedy School, and Clark University have uncovered that conflict with communities is costing mining companies billions of dollars.
Fences cause 'ecological meltdown'
The use of fenced areas to protect threatened species in the wild should be a last resort, argue scientists from the Zoological Society of London (ZSL) and the Wildlife Conservation Society (WCS).
Novel optical fibers transmit high-quality images
After having recently discovered a new way to propagate multiple beams of light through a single strand of optical fiber, engineers at the University of Wisconsin-Milwaukee (UWM) now have found that their ...
Coral chemicals protect against warming oceans
Australian marine scientists have found the first evidence that coral itself may play an important role in regulating local climate.
Adaptability to local climate helps invasive species thrive
University of Toronto research has found that purple loosestrife – an invasive species that competes with native plants for light and nutrients and can degrade habitats for wildlife – has evolved extremely ...
