Chinese nanotechnologists injected tiny particles into the eyes of mice resulting in the rodents demonstrating "infrared 'night vision'" that lasted for months. According to nanoscientist Tian Xue and colleagues the University of Science and Technology of China, the technology could eventually help those with certain kinds of color blindness and "provide the potential for close integration within the human body to extend the visual spectrum." From New Scientist:
Like humans, mice cannot perceive light with a wavelength longer than 700 nanometres, which is at the red end of the visible spectrum. But the nanoparticles absorb light with longer – infrared – wavelengths and convert it into shorter wave light that retinal cells can detect. This converted light peaks at a wavelength of 535 nanometres, so the mice see infrared light as green...
Some mice did develop cloudy corneas after the injection, but this disappeared within a fortnight and occurred at similar rates to those in the control group. The team found no other evidence of damage to the mice’s eyes two months after the experiment.
The researchers published their findings in the scientific journal Cell: "Mammalian Near-Infrared Image Vision through Injectable and Self-Powered Retinal Nanoantennae"
I’ve had quite a few fun afternoons playing with dry ice from making spooky fog in the kitchen to exploding plastic bottles in the yard. But I’ve never had the opportunity to pour hot lava over dry ice. In this video, the lava is 1400 °C and the dry ice is -78C°. So cool! And […]
A Boston University team have developed an acoustic, 3D-printed metamaterial whose topology is such that it reflects 94% of human-audible sound; the researchers' demonstration involves inserting a ring of this stuff in a PVC pipe and blasting a speaker down one end: light and air emerges from the other end, but sound does not.
Scientists Lior Appelbaum and David Zada in Israel publish new proof that sleep serves to help our brains repair damage.
