DNA Nanobots Set To Seek and Destroy Cancer Cells In Human Trial
This year, researchers hope that tiny robots built entirely of DNA will help save a critically ill leukemia patient. These DNA nanobots are designed to seek out and destroy cancer cells, while leaving healthy cells unscathed. So far, they’ve only been tested in cell cultures and animal studies.
....“No, no it’s not science fiction,” he said. "It’s already happening."
The technology is modeled after our body’s own defenses. Like white blood cells, the nanobots patrol the bloodstream, looking for signs of distress. DNA is a naturally biocompatible and biodegradable material, and the devices are designed to not incite an immune response.
....The patient selected for this year’s early trial has been given only a few more months to live. The team expects to remove the cancer within one month.
[DNA nanobots] will deliver enzymes that break down cells via programmable nanoparticles.
Delivering insulin to tell cells to grow and regenerate tissue at the desired location.
Surgery would be performed by putting the programmable nanoparticles into saline and injecting them into the body to seek out remove bad cells and grow new cells and perform other medical work.
One Trillion 50 nanometer nanobots in a syringe will be injected into people to perform cellular surgery.
The DNA nanobots have been tuned to not cause an immune response.
They have been adjusted for different kinds of medical procedures. Procedures can be quick or ones that last many days.
Medicine or treatment released based upon molecular sensing - Only targeted cells are treated
Using DNA origami and molecular programming, they are reality. These nanobots can seek and kill cancer cells, mimic social insect behaviors, carry out logical operators like a computer in a living animal, and they can be controlled from an Xbox.
......This is programmable dna nanotechnology.
.....A friend once mentioned his thoughts were of experiments to try and vaccinate people in case of bioterrorism. I recall some of the more out-there thoughts were of self-organizing nanobots in this airborne mix of unknowns. The time frame matches with the second video mentioning work on organizing dna into various shapes starting 3 decades ago ,and becoming perfected some 7 years ago. Interesting. ....

The trouble with Tribbles....
Imagine what other mission they could be used for.
Do YOU trust your government that much?
I have a chronic, serious medical issue and I say hell no, I'll pass.

You know a lot about Crichton's hypotheses (eg. nano-swarms) considering you haven't read him. Oh wait! Did you mean Bachelet? Did he talk about swarms too? (Missed it if he did.)
fyi - While the entrepreneurs are talking about extending health spans and lifespans, fact is, our health spans and lifespans have greatly diminished over the past couple of centuries. Used to be if you made it out of childhood and through doctor attended childbirth, you were good to go for 10-odd decades. Now - you're lucky if you can still get it up at 40 and don't need diapers at 50. Not an improvement by any standard.
As far as engineering future generations to handle space, we're already epigenetically equipped to respond rapidly to environmental change and adapt - without messing up our hard drives. Why fix what ain't broke?
Re: Near-speed-of-light space travel. I'm waiting for the iWormhole.
Epigenetics is like flagging commands for scripts to be run. You can change the way in which the code is run, but the underlying architecture remains. We still have biological limits as we are, which can be surpassed with the tinkering. That would be like upgrading the programming language to create new architectural suites. I'm all for it. No fear at obsolescence of homo sapiens.
