Scientists inject nano particles into mice to give them "infrared vision"

Crime fighting 'superdogs' with in-built night vision could one day be created as scientists claim an injection of nanoparticles can give animals the ability to see infrared light
Superdogs with infrared night vision could soon be created and used to chase down criminals.
Scientists have successfully given mice the ability to see near infrared wavelengths of light for up to ten weeks thanks to an injection of nano particles into their eyes.
Scientists are now saying dogs could be the next step, with humans the ultimate goal if the safety of the procedure can be ensured.
'If we had a super dog that could see near infrared light, we could project a pattern onto a lawbreaker's' body from a distance, and the dog could catch them without disturbing other people,' Dr Han from the University of Massachusetts Medical School said.
Night vision goggles are already an essential piece of equipment for soldiers, spies and sci-fi heroes but the nanoparticle injection can directly give animals the ability.
The researchers found the chemicals gave mice the ability to see more wavelengths of light than they can naturally.
The results are to be [presented this week at the American Chemical Society (ACS) Fall 2019 National Meeting & Exposition.
'When we look at the universe, we see only visible light,' says Dr Gang Han, the project's principal investigator.
'But if we had near-infrared vision, we could see the universe in a whole new way.
'We might be able to do infrared astronomy with the naked eye, or have night vision without bulky equipment.'
Most mammals can only detect light of wavelengths between 400 and 700 nanometers (nm).
Near-infrared (NIR) light, on the other hand, has longer wavelengths - 750 nm to 1.4 micrometers.
Upconversion nanoparticles (UCNPs) were injected into their eyes which contain the rare-earth elements erbium and ytterbium.
They can convert low-energy photons from near infrared light into higher-energy green light that mammalian eyes can see.
To determine whether the injected mice could see and mentally process NIR light, the team conducted several physiological and behavioral tests.
For example, in one test, the researchers placed the mice into a Y-shaped tank of water.
One branch of the tank had a platform that the mice could climb on to escape the water.
The researchers trained the mice to swim toward visible light in the shape of a triangle, which marked the escape route.
A similarly lit circle marked the branch without a platform. Then, the researchers replaced the visible light with NIR light.
'The mice with the particle injection could see the triangle clearly and swim to it each time, but the mice without the injection could not see or tell the difference between the two shapes,' says Dr Han.
The success of the injections lasted for ten weeks but the researchers say improving the safety is of paramount importance before it can be used in humans.

2019-08-28 at 9:28 PM UTCWasn't there a nightops thread on one of these sites that had someone using some sorta drug to increase his night vision?The following users say it would be alright if the author of this post didn't die in a fire!

Probably. Nightshade eye-drops might work too since scopalamine and other tropane alkaloids dilates the pupils so much.The name belladonna is derived from Italian for "beautiful woman", as during the Renaissance, the herb was used in eyedrops by women to dilate the pupils of the eyes to make them appear seductive.
https://en.wikipedia.org/wiki/Atropa_belladonnaA safe concentration of atropine is used in eye drops to make the pupils dilate so that a doctor can examine the inside of the eyes properly. (The pupil is an opening in the middle of the iris that allows light to enter the eye.) The pupils may stay dilated for several days after an atropine treatment.
I have no idea how it would affect night vision, but I'm guessing if used carefully it would enhance it to some extent, although the vision may be more blurry while night vision is enhanced. -

I got shot in the eye as a kid and had to have eye drops and hospital visits for months and I don't remember anything like that, though it was a long time ago and I don't know if I'd have been in the dark much after the drops. -

Came here to post this. It was by "cognition" or something like that and supposedly used the same chemical
Edit: nope, it was "psychlonic"

That was cool. Glad someone else is researching that.
