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.
Researchers successfully revived ancient microbes, some more than 100 million years old, that were buried in the seafloor. During an expedition to the South Pacific Gyre, the scientists from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and their colleagues drilled into the ocean sediment almost 6,000 meters below the surface. “Our main question […]
My family stopped wiping down all our groceries to “disinfect” them a couple months ago, mostly because of hygiene exhaustion. Then in May, the Center for Disease Control and Prevention clarified its own Web page about how COVID-19 spreads to state that “based on data from lab studies on COVID-19 and what we know about […]
If the last 50 years of education have taught us nothing else, it’s that it often requires different tactics to best reach different learners. To pick up a foreign language, some students take best to the old-school high school language lab method, using heavy repetition, verb conjugation and grammar emphasis to embed a new language. […]
For those who want a career in video games, there’s no reason to sit around and wait. EA and Rockstar Games probably aren’t going to seek you out and knock on your door with a job opportunity. But if you’re an indie developer with a good idea and some passion, you can create a really […]
Nobody is happy about the current state of our COVID-ravaged education system. With a new school year fast approaching, plans for teaching students still in flux, and political in-fighting driving more fear and confusion about whether or not to re-open campuses, teachers and parents are concerned. Meanwhile, most kids are just fine with spending less […]
