For the first time, a pig kidney has been transplanted into a human without triggering immediate rejection by the recipient's immune system, a potentially major advance that could eventually help alleviate a dire shortage of human organs for transplant.

The procedure done at NYU Langone Health in New York City involved use of a pig whose genes had been altered so that its tissues no longer contained a molecule known to trigger almost immediate rejection.

The recipient was a brain-dead patient with signs of kidney dysfunction whose family consented to the experiment before she was due to be taken off of life support, researchers told Reuters.

For three days, the new kidney was attached to her blood vessels and maintained outside her body, giving researchers access to it.

Test results of the transplanted kidney's function "looked pretty normal," said transplant surgeon Dr. Robert Montgomery, who led the study.

Awesome progress here. Could be a big money saver, considering how long transplant patients need to sit on a waiting list getting expensive treatments in the meantime. Plus you could name your donor pig and make fun videos for your social media, before it's butchered just for you.

This is pretty cool. Launching satellites by spinning it really fast. 10,000G, so probably not suitable for people, or monkeys.

This would be huge. Vaccinating against and even reversing Alzheimers.

For background, this is a great comic/info graphic. They continue to do some really amazing stuff.

Thanks for the video. 10b gamble is right. I sincerely hope it overcomes all 500 obstacles it has to just to operate. 1 glitch, 1 spec of dirt flies through that things heat shield and its all lost.

Still, what an impressive piece of tech and I hope to see what it can produce.

Congrats to the ESA for a flawless launch, now the 30 days of nail biting for full deployment and placement.

6 months for first pictures. I can't wait!

That was a fun thing to watch.

Amazing engineering, finding solutions for such almost mundane things like pushing a string down a wire.
I'm really hoping this will all work out and be successful, having the ability to find the dimmest stars is unreal and who knows what discoveries will come of this.

A cool animated video of all the unfolding that will occur. Just to make us all extra nervous with all the moving parts

fingers crossed!

The launch was the easy part, I think.

The 300+ movements over the next week while they deploy the heat shield is gonna tense AF lol.

If there is a problem that can't be solved remotely is this space junk? Or can they return it to Earth orbit and repair. Probably not but wondering.

Junk. High stakes. Which is part of why it’s been delayed so many times.

Unlike Hubble, the Webb telescope won't be serviceable. This is a one-shot deal.

I recall that the mirrors on the Hubble were eroded by something like 1000 nanometers after the launch, so the initial images were blurry. Astronauts were able to basically install correction lenses to fix the issue. They considered that this time and made the mirrors from different materials and they have moveable parts so it can at least calibrate in the event of some damage.

I think the riskiest part is that meteors the size of sand or pebbles might shred the heat shield. They reinforced the materials to take that into consideration but it is still a big risk. The Webb telescope won't last forever and is relying a lot on luck since there is no way to know everything that is flying around out there. Much of it is just too small to detect from Earth. Hopefully they get some good years out of it.

I am curious about what practical knowledge they hope to gain from it. All I keep reading is that they want to get images from the early formation of the universe, which sounds super cool. But there seems to be little talk about what practical applications that knowledge will give us. I assume there is something and it isn't just a vanity project, but I really want to know.
