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 large black bear in this video was observed ambling around a Monrovia, California neighborhood last Friday morning. The bear walked through residential lawns, driveways and rested in a nearby alley.
How does an owl’s tail help it fly? To better see the role of the tail in raptor aerodynamics, researchers at the UK’s Royal Veterinary College recorded birds of prey flying through clouds of tiny helium bubbles. According to the science journal Nature, analyzing the swirling motion of the bubbles enabled the scientists to discover […]
Thirty years ago today, the Voyager 1 spaceprobe had completed its ncounters with the outer planets and was careening out of our solar system. The time came to shut off the probes’ cameras to preserve power and memory for the other onboard scientific instruments. But before engineers flipped the switch, one last photo opportunity was […]
In our modern world, our usual first approach to combating an oncoming cold is to medicate it into oblivion. Sometimes, that carpet bombing pharmaceutical attack plan can knock out the congestion and discomfort of an illness before it settles in. But there’s always something to be said for trying to put down the effects of […]
Whether you’re managing a political campaign or building a client base, there comes a time when you stop seeing people and start seeing numbers. This doesn’t happen suddenly. You shake hands, make calls, and build relationships. And then those relationships disappear into a database of donors or customers as your organization grows. People get brought […]
Learning to ride a bike is one of those quintessential childhood experiences that’s as rewarding as it is scary. Prep your precious babe for success by starting them early with the world’s lightest balance bike, the Brilrider FLIGHT. For the uninitiated, balance bikes are no-pedal bicycles that propel forward by pushing off the ground with […]
