spacecity1971··on Robot dentist performs first human procedure
Fantastic development (I’m in the dental field) As a side note; a Chinese team already performed an implant surgery with a “fully automatic” robotic system in 2017.

spacecity1971··on Possible Meissner effect near room temperature: copper-substituted lead apatite
Great to see research continuing on this particular path.
spacecity1971··on E-bandages lightly zap and heal wounds
I wonder if this team has considered making the electrodes out of silver? Robert O. Becker had great success accelerating the healing of bone tissue using similar methods. Seems like this would avoid any toxicity issues.
spacecity1971··on E-bandages lightly zap and heal wounds
Good to see Robert O. Becker finally getting some recognition for a lifetime of work.
spacecity1971··on Silurian Hypothesis
What if the more difficult to explain parts of the UAP phenomenon is our experience of the remnant of that previous civilization? It never went extinct, it just moved into space and the bottom of the oceans. We're ants, unaware of the civilization that surrounds us because it is to alien/advanced for us to comprehend.
spacecity1971··on A new doorway to the brain
I guess fMRI isn’t really a good analog. What is needed is an MRI quality video sequence showing movement. Dynamic planning would allow occlusal schemes to be designed more accurately, therefore avoiding many common issues with full arch rehab, for example.
spacecity1971··on A new doorway to the brain
No, but it’s a step closer. CBCT is the standard right now, but it has limitations like poor bone density measurement and no dynamic imaging.
spacecity1971··on A new doorway to the brain
An fMRI quality imaging system would allow dynamic planning for a full arch implant retained prosthesis, for example.
spacecity1971··on A new doorway to the brain
As a dental professional working with oral/maxillofacial surgery teams, I can’t wait for fMRI quality imaging in a portable affordable device. First to market with such systems will make a fortune.
spacecity1971··on Scientists are using AI to dream up revolutionary new proteins
Would love to contribute, please contact me at variofab(at)icloud(dot)com
spacecity1971··on Dall-E 2
Or, it’s a demonstration that AI output can be controlled in meaningful ways, period. Surely this supports openai’s stated goal of making safe AI?
spacecity1971··on Technology Behind the Lilium Jet
Agree re simplicity. Ehang has been using what is essentially a consumer drone design for some time, and has demonstrated success with many flight tests. Although they aren’t using the most efficient design, I wouldn’t be surprised if they dominate the short range air taxi field.

Your intuition is correct, and it’s already been done:

spacecity1971··on Elon Musk Has No Idea What He’s Doing with Tesla Bot
Tesla is an infrastructure company. He’s building infrastructural components for Mars as much as Earth, for sure.
spacecity1971··on AlphaFold Protein Structure Database
Quick question, please excuse my ignorance, but is there a way to extrapolate sequence from structure? In other words, can we design proteins and calculate the sequence required to make it?
spacecity1971··on 2-Acre Vertical Farm Run by AI and Robots Out-Produces 720-Acre Flat Farm
Cultured/printed meat.
spacecity1971··on Project Cybersyn
The chairs make perfect sense in the context they were used, and this was all built on a shoestring budget by hand. The bare bones Cybersyn was actually used during the trucking strike in Chile, and Beers theories worked perfectly. The whole thing is worth digging further into to fully comprehend the design decisions that were made.
spacecity1971··on Portable MRI promises to provide immediate diagnosis in virtually any setting
Her tech is very promising. They have apparently undergone initial FDA certification for device classification, so I’m also very curious to see how they progress.
spacecity1971··on GPT-3 has no idea what it’s talking about
Yes, this! The point being missed by most is the very real possibility that the Scaling Hypothesis is true. If it is, then we're seeing some kind of reasoning intelligence emerge. GPT-3 obviously isn't there yet. Unless it's faking it (Yudkowsky)...
spacecity1971··on Moxie, a Social Robot That Helps Kids with Social-Emotional Learning
I agree that there may be specific use cases where this type of robot can help. My reaction is more to how it is portrayed in the video. The child appears to be depressed, with parents who show almost no interactive ability. I fear that this actually happens with increasing frequency, and that it represents a societal failure. Maybe we need these bots for the parents?
spacecity1971··on Moxie, a Social Robot That Helps Kids with Social-Emotional Learning
This is a good question. I think the differences may lie in the perceived anthropomorphism and the difference that makes psychologically. Books, clothing etc are passive objects that utilize the imagination of the user in a definite way, whereas a talking robot with facial expressions taps into a specific set of neural/emotional cascades that, IMO, should be reserved for human interaction exclusively.
spacecity1971··on Moxie, a Social Robot That Helps Kids with Social-Emotional Learning
Shouldn't parents be doing this? If they're not, then why did they have a kid? The robot seems well designed, inoffensive, and the company's focus is well intentioned, but I can't help thinking that this represents a complete societal failure on so many levels.
spacecity1971··on Online installment loans have taken the subprime market by storm
I think, instead of minimum wage hikes etc, that maybe putting a cap on the ratio of CEO pay to entry level employee would work more effectively.
spacecity1971··on Tiny lensless endoscope captures 3-D images of objects smaller than a cell
Nanolive.ch is doing this quite well, high enough resolution to make structures like mitochondria clearly visible. Also able to make time lapse of living cells. (I don’t have any business connection to Nanolive, just an Instagram follower)
spacecity1971··on China’s Spying Poses Rising Threat to U.S.
Platform warfare indeed, and this is completely overlooked as a concept. Bratton (2015) described this new geopolitical architecture in detail, and we ignore it at our peril.
spacecity1971··on William S. Burroughs’ Manifesto for Overthrowing a Government with Fake News
Reads more like instructions for constructing a Basilisk to me.
spacecity1971··on What's behind Mediterranean diet and lower cardiovascular risk
Valter Longo’s research has a good explanatory framework for this effect. For an introduction, The Longevity Diet (2016) is worth a read.
spacecity1971··on Scientists are working to eliminate senescent cells
Valter Longo has conducted human studies pointing to the veracity of this effect, at least with MS patients. Certainly early days yet, but compelling nonetheless. https://www.sciencedaily.com/releases/2016/05/160526151941.h...
spacecity1971··on Scientists are working to eliminate senescent cells
As documented by Dr. Rhonda Patrick (and others), fasting can trigger cellular autophagy and reduce senescent cells without the use of drugs. https://www.foundmyfitness.com/news/t/fasting
spacecity1971··on Hyperloop One Becomes ‘Virgin Hyperloop One’
I wonder if the tube could be continuously woven from carbon fiber and given an aerogel insulating wrap, then the interior coated with ceramic? This would perhaps mitigate heat expansion issues.
