The following submission statement was provided by /u/chrisdh79:


From the article: Researchers from the University of Cambridge have created a new type of neural implant that could restore limb function in paralyzed limbs.

The developed device works in sync between the brain and paralyzed limbs - it combines flexible electronics and human stem cells to "better integrate" with the nerve and drive limb function, according to a press release.

There have been former attempts at using neural implants to restore limb function, but these mostly failed. This is because scar tissue can envelop the electrodes over time, disrupting the connection between the device and the nerve.

"If someone has an arm or a leg amputated, for example, all the signals in the nervous system are still there, even though the physical limb is gone,” said Dr. Damiano Barone from Cambridge’s Department of Clinical Neurosciences, who co-led the research, said in a statement. "The challenge with integrating artificial limbs, or restoring function to arms or legs, is extracting the information from the nerve and getting it to the limb so that function is restored."

The researchers combined cell therapy and bioelectronics into a single device, improving functionality and sensitivity.

In this case, they sandwiched a layer of muscle cells that were reprogrammed from stem cells between the electrodes and the living tissue. This led to device integration with the host's body, preventing the formation of scar tissue. For the time time, the cells survived on the electrode for 28 days - the duration of the experiment.

First, the researchers designed a biocompatible flexible electronic device thin enough to be attached to the end of a nerve. According to the release, a layer of stem cells, reprogrammed into muscle cells, was then placed on the electrode.

In recent years, humanity managed to develop a tractor beam that can move around objects at the millimetre scale with beams of light.

Before that, we naturally had beams that could move things at the atomic scale. With the right configuration of lasers, power, and control software, I imagine it would be technically possible to use this technology to construct something atom by atom, though it would be painstakingly slow.

So we do have replicator technology. It’d just take years to produce a single tea, earl grey, hot right now, rather than seconds. Not exactly practical, but still interesting nonetheless.

> Never believe that anti-Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti-Semites have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past.

The emissions and environmental footprint of lubricant oil in a wind turbine is insignificant compared to the footprint of directly burning fossil fuels for the same amount of energy. It's like thinking the motor oil you put in your car is anywhere near as much of a problem as the gasoline you burn every time you touch the pedal. You even make this connection yourself and then don't follow the thought anywhere.

Fiberglass is a durable composite material that's been used in homes and vehicles and elsewhere and then landfilled for decades. The importance you attach to "thing end up in hole" doesn't seem tied to any particular concern regarding the environment or human health or sustainability substantiated by research.

>It's JUST conservatives who are questioning whether or not these things are really that environmentally conscious.

Total nonsense. Environmental scientists publish life cycle assessments of renewable and conventional technologies all the time. It's a well established field of study. There are many comprehensive reports that highlight real concerns e.g. dirty production of turbine steel, they're literally just a google scholar search of "wind power LCA" away.

You're not a critical thinker if you just pick a twitter pundit/similar who appeals to your preconceived notions and uncritically regurgitate their disingenuous bullshit.

We know exactly everything that can and Will happen.

There are 2 scenarios:

  1. Single gestalt consciousness of AI, once it starts to create it's own tasks. At this moment tech will either stop advancing, coz AI will understand the usefulness of existence, or it will do it's tasks without stopping. Humans will be an obstacle, either to be ignored completely or to get rid off.

  2. Before gestalt, people will use AI as a tool to control the power over others. Through propaganda, fake world, fake artists and so on. This scenario is already happening in China.

In both cases, freaks, that are working on it, are responsible for the caused chaos. Because they should have been understanding that even before starting the work. Also, just look on the ClosedAI. They are the embodiment of everything bad, that could happen with the AI development.

So, if we're keeping track, you came out swinging with a pretty aggressive response to an industry professional who was explaining things in very calm and simple terms, and then when they rightly took you to task for the very basic errors you made, all of a sudden they're being a dick and the discussion isn't civil? Maybe you should try a civil response to begin with and maybe the conversation might head to sunnier pastures, friend?

You certainly aren't a power systems engineer, so why mention your qualifications at all? They aren't meaningful here.

Hi, 2farzzz. Thanks for contributing. However, your submission was removed from /r/Futurology.

> Rule 10 - We welcome text posts, but could you please ensure they meet our requirements for creating in-depth discussion. If yours is removed for failing to do so, consider reposting again, but with additional detail.

Avoid generalized invitations to discuss frequently discussed topics (Will AI take over the world? Is Chat-GPT good or bad, etc, etc). Instead, aim for discussion with specific topics (with supporting links if possible), and give detail to the ideas about their future implications that you would like to see discussed. If possible articulate multiple aspects of these future implications to encourage high quality discussion.

Submissions with [in-depth] in the title have stricter post length and quality guidelines.

> > With the technology we have today we have seen how we can use drones to drop grenades over people's head (like in Ukraine), and I don't think I'm the only one who fears this going mainstream. I don't know about other nations, but I'm pretty sure the US and other Nations like China have resources that can be thrown at people without having to take life. I know I know, I'm being naïve here, but considering the amount of technology we have today, and the budget these giant nations have, we can probably have it so that a drone can go in and fire something like "containment foam" (worm reference-so fictional, but worth looking to making real) to incapacitate combatants. A number of weapons have been banned by the UN because it increases suffering and harm, and we now have resources that we can employ to have "clean" wars where life isn't taken or lost. If people do start employing drones with lethal armaments we can fire EMPS to deactivate them and maybe recover and recycle the drones. So I'm interested in signing a petition if it exists. > > It would probably be more costly to have "clean" wars, meaning there would be money in it, so I don't think it would be a worthless industry. > > Who knows maybe there are people working on "de-arming" militaries or non-lethal options. Hopefully we can get to a point where we can remove most guns out of circulation and have them recycled for better uses than to cause harm.
