Scientists refine formula for nanotube types
(Phys.org) —Many a great idea springs from talks over a cup of coffee. But it's rare and wonderful when a revelation comes from the cup itself.
Researchers use liquid inks to create better solar cells
(Phys.org) —The basic function of solar cells is to harvest sunlight and turn it into electricity. Thus, it is critically important that the film that collects the light on the surface of the cell is designed ...
Researchers create materials that reproduce cephalopods' ability to quickly change colors and textures
Cephalopods, which include octopuses, squid, and cuttlefish, are among nature's most skillful camouflage artists, able to change both the color and texture of their skin within seconds to blend into their ...
A promising light source for optoelectronic chips can be tuned to different frequencies
Chips that use light, rather than electricity, to move data would consume much less power—and energy efficiency is a growing concern as chips' transistor counts rise.
Chandra X-ray Observatory finds planet that makes star act deceptively old
(Phys.org) —A planet may be causing the star it orbits to act much older than it actually is, according to new data from NASA's Chandra X-ray Observatory. This discovery shows how a massive planet can affect ...
Nanoribbon film keeps glass ice-free: Team refines deicing film that allows radio frequencies to pass
Rice University scientists who created a deicing film for radar domes have now refined the technology to work as a transparent coating for glass.
Scientists twist radio beams to send data: Transmissions reach speeds of 32 gigabits per second
Building on previous research that twisted light to send data at unheard-of speeds, scientists at USC have developed a similar technique with radiowaves, reaching high speeds without some of the hassles that ...
Nanocontainers for nanocargo: Delivering genes and proteins for cellular imaging, genetic medicine and cancer therapy
Human faces are so variable because we evolved to look unique
The amazing variety of human faces – far greater than that of most other animals – is the result of evolutionary pressure to make each of us unique and easily recognizable, according to a new study by ...
Pottery shards offer evidence of pulque production in prehispanic Mesoamerica
Researcher figures out how sharks manage to act like math geniuses
Researchers find parking space solution in PocketParker
Slimy fish and the origins of brain development
Lamprey—slimy, eel-like parasitic fish with tooth-riddled, jawless sucking mouths—are rather disgusting to look at, but thanks to their important position on the vertebrate family tree, they can offer ...
Global importance of pollinators underestimated
(Phys.org) —Declines in populations of pollinators, such as bees and wasps, may be a key threat to nutrition in some of the most poorly fed parts of the globe, according to new research.
