By injecting specialized light-tweaking nanoparticles into a mouse’s retina, that mouse is suddenly and clearly able to perceive near-infrared light — suggesting the same could be possible for us, assuming you don’t mind a needle in the eye.
The advance involves what the researchers, from the University of Science and Technology in China, call “ocular injectable photoreceptor-binding upconversion nanoparticles.”
In fact, it turns out that these researchers had already created the necessary trickery for a different reason, namely as a molecule for optogenetic triggers that would absorb infrared light (which conveniently penetrates many tissues) and emit visible spectrum light instead.
These “nanoantennae,” as the researchers call them, are biocompatible and can be combined with proteins that encourage them to bind with the photoreceptive cells in our retinas. What happens when you coat a cell that normally detects green light with a molecule that absorbs NIR radiation (900-1000 nm) and outputs something 500 nm shorter? That cell can effectively now sees IR as a shade and intensity of green.
That’s exactly what happened when the team injected these molecules into the eyes of mice ... the animals were instantly able to detect NIR in a variety of circumstances. Not only did a beam of IR cause their pupils to constrict, but patterns projected in IR indicating a reward were reliably sought by the mice, indicating this was not just a general awareness but detailed perception in the wavelength.
The molecules also seemed to cause no serious problems in the retina, such as cell death or irritation — and the mice were still able to see in IR some 10 weeks after injection.

I want to see in IR.
This should be a cheap procedure.
Maybe someday.
Requires very high electric field strengths; high enough to significantly alter the dielectric constant of the surrounding medium.
riddick movies
Just call me "Rip," Rip van Winkle. Never heard of it.
was a pretty good action science fiction movie- he got his ‘eyes shined’ in lockup in crematorium i bleive it was where it was dark- now he sees in the dark- in onem ovie he has to navigate a group of peopel from a distant planet through a hoard of aliens, at night, well- chek out a youtube clip for an idea of how the movie is- it’s a pretty cool take on sci fi-
“assuming you don’t mind a needle in the eye”
As a treatment for macular degeneration, I have to get a needle in the eye every one or two months an avastin injection. Of course they apply numbing drops beforehand.
It isn’t fun or pleasant but it is necessary if I want to see out of that eye.
“Very COOL movie :)
One of few believable tough guy actors to come to the screen in the past 20 years.”
Pitch Black is one of the most underrated scifi films of the last 25 years. It was also the only Scifi of any kind I’ve seen where a multiculturist future might actually work. And it didn’t rub it in your face.
“The Chronicles of Riddick, also called Pitch Black...”
These are two different movies that share one common character.
“Steve Austin, astronaut. A man barely alive. Gentlemen, we can rebuild him. We have the technology...”
Thanks BenLurkin. I've had a doctor stick a needle into my eye before, it's not as nice as it sounds.
Its confusing but the order of the series is:
1) Pitch Black
2) The Chronicles of Riddick
3) Riddick

The Avastin injections are to suppress VEGF or Vascular Endothelial Growth Factor, a micro RNA that causes angiogenesus or capillary growth. This is the bodies response to hypoxia or oxygen deficiency.
When Zeazanthin, one of the two primary xanthophyll carotenoids contained within the retina of the eye is transmuted to drusen, the result is oxygen deficiency, especially if you have sleep apnea. Zeazanthin is the pigment that gives paprika, corn, saffron, wolfberries, and many other plants and microbes their characteristic color yellow. It is also high in spinach, so popeye was correct!
I helped a woman getting the Avastin shots to reverse the process and get her sight back, primarily with dietary changes, as the zeazanthin/ drusen change in the retina causing the problem is reversable.
In my friend’s situation, anemia was causing her red blood cells to carry insufficient oxygen. Thus correcting the underlying cause and proper nutrients caused reversal. She has not received the Avastin shots in years and her sight has improved.
I’m a medical intuitive and this stuff just flows into my mind. I then back it up with evidence based research. I worked with her years ago, even before the zeaxanthin supplements were on the market.
I haven’t read the article, but will as curiosity puzzles me as to how the injections altered the rods, or higher frequency photo receptor neurons in the retina.

Excellent!
I’m not a typical medical intuitive. I’m more of a walking MRI. It’s as though I feel what is going on in a person’s body just by being near them.
It goes way, way beyond that. I physically feel the stored memories of people’s life experiences since conception as I walk up to them.
It even goes way beyond that. You can blindfold the person, I say nothing and do not touch their body in any way, and often knock them off their feet by touching dense emotional memories in their soul 10 to 15 feet from their physical body.
It goes beyond that, but I’ve shared more than I should have already.
I use this ability to demonstrate why Jesus taught what He did.
It’s all based upon frequencies of consciousness in a person’s soul.
