University of Utah electrical and computer engineers have discovered a way to create an optics-less camera in which a regular pane of glass or any see-through window can become the lens.
The idea that light has momentum is not new, but the exact nature of how light interacts with matter has remained a mystery for close to 150 years. New research from UBC's Okanagan campus, recently published in Nature Communications, may have uncovered the key to one of the darkest secrets of light.
When a shipwreck is brought up from the sea depths, the wood quickly starts deteriorating. Scientists are reporting a novel way to use 'smart' nanocomposites to conserve a 16th-century British warship, the Mary Rose, and its artifacts. The new approach could help preserve other salvaged ships by eliminating harmful acids without damaging the wooden structures themselves. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
Blood banks around the world are continually in need of type O blood, which can be universally administered in an emergency. Researchers have identified an enzyme that converts A- and B-type blood to O with 30 times more efficiency than previously studied enzymes. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
For thousands of years, people in the Middle East and South America have extracted water from the air to help sustain their populations. Drawing inspiration from those examples, researchers are now developing a lightweight, battery-powered freshwater harvester that could someday take as much as 10 gallons per hour from the air, even in arid locations. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
Once in the territory of science fiction, 'nanobots' are closer than ever to becoming a reality, with possible applications in medicine, manufacturing, robotics and fluidics. Today, scientists report progress in developing the tiny machines: They have made nanobot pumps that destroy nerve agents, while simultaneously administering an antidote. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
A team at NYU Tandon School of Engineering has found a way to prove the provenance of 3-D printed parts by embedding QR (Quick Response) codes in an innovative way for unique device identification. In the latest issue of Advanced Engineering Materials, the researchers describe converting QR codes into 3-D features so that that they neither compromise the part's integrity nor announce themselves to counterfeiters who have the means to reverse engineer the part.
An infrared look by NASA's Terra satellite found powerful storms in the center of Tropical Storm Cimaron that resembled a 'Picasso-like' face as they zig-zagged around the center of circulation.
Hurricane Lane had moved westward into the central Pacific Ocean far southeast of the Hawaiian Islands when NASA's GPM core observatory satellite passed above and looked it the heavy rainfall it was generating. Hurricane Lane may be a threat to portions of the Hawaiian Islands this week.
A new biosensor allows researchers to track oxygen levels in real time in 'organ-on-a-chip' systems, making it possible to ensure that such systems more closely mimic the function of real organs. This is essential if organs-on-a-chip hope to achieve their potential in applications such as drug and toxicity testing.
