LLMs were designed to generate coherent statements, but not necessarily correct ones, and are unable to consistently spot logical fallacies in their output. Humans can do this (some better than others), so computers should be capable of this too. The technology is not there yet, but I’m glad people are working on it.
the researchers dipped or soaked brain organoids (brain tissue grown from stem cells) in a mix of ethylene glycol, methylcellulose DMSO and Y27632 (called MEDY) for the cryopreservation of cortical organoids.
They later tested the solution under various conditions to observe the extent to which it could prevent damage.
It involved changing variables, such as the age of the organoids before freezing and how long they were soaked in the solution.
The researchers then allowed the organoids to resume growing after they were thawed for up to 150 days. The researchers observed minimal differences between organoids that had been frozen and those that had not, even in organoids frozen for as long as 18 months, according to Medical Express.
Neat stuff. Still a ways away from freezing a whole brain or organism, but nice incremental steps.
TL;DR: Still no “optical transistor” yet, but they figured out a way to do matrix multiplication:
The researchers encoded the various quantities they wanted to multiply into beams of light, then sent the beams through a series of components that altered the beam’s phase—the way its light waves oscillated—with each phase alteration representing a multiplication step. By repeatedly splitting the beams, changing their phase, and recombining them, they could make the light effectively carry out matrix multiplication. At the end of the chip, the researchers placed photo detectors that measured the light beams and revealed the result.
To qualify, a proposed well site must have the appropriate geology, with a deep reservoir of porous rock that can accommodate carbon dioxide molecules sitting below a layer of nonporous “cap rock” like shale.
Is this criteria sufficient? It’s a bit unclear what they mean by “accommodate carbon dioxide molecules”, but it seems like there is a risk of the CO2 leaking back out.
I’ve heard of some storage plans which use the local geology to turn the CO2 into carbonate minerals, eliminating the risk of rerelease. Obviously, this is highly dependent on the presence of the appropriate minerals, and can’t be deployed everywhere.
Would it not be the case of simply sandwiching the computers between a solar panel and a radiator? Or would the radiator need to be larger than the solar panel?
I am familiar with how space radiators work, but thanks for the clarifications. A sandwich design is definitely not optimal for a diffuse swarm of satellites in earth orbit.
I think my confusion stemmed from the fact that I was envisioning a dense swarm of these in solar orbit, rather than earth orbit.
In this case, I don’t think a 90 degree offset radiator panel would work, as it would primarily heat up the neighboring panels, and vice versa. The only direction available to radiate energy is directly away from the sun. I would be curious to know what fraction of the energy would need to be devoted to thermal management. The smaller the radiator, the hotter it needs to operate to emit the same amount of heat.
I wonder if it would be possible to make flat, high-temperature electronics which could be used as the radiator? Just pop them on the back of a solar panel and you’d be good to go!
Nice profile picture… Tim. Are you aware of !hellointernet? It’s not very active, but that’s sort of to be expected in the given circumstances. Just thought I’d let you know in case you missed it.
Lee’s research team “stumbled” on the discovery after investigating a “gene desert”, a stretch of DNA on chromosome 21 that does not code for proteins, which has previously been linked to IBD and other autoimmune diseases. Writing in Nature, they describe how they found a section of DNA that behaves like a volume control for nearby genes. This “enhancer” was seen only in immune cells called macrophages where it boosted a gene called ETS2 and ramped up the risk of IBD.
Sounds like more “junk” non-coding DNA turns out to be not junk after all. I wonder how much of our DNA is actually junk, and how much we just don’t know yet.
AI should allow us to analyze the logic in politicians’ speeches in real-time. There are over a hundred logical fallacies, and they are a standard part of political debate.
This seems interesting. For starters, I wonder if a model could be trained to spot logical errors in mathematical proofs. That in itself could be a useful tool for mathematicians, but it seems like an error detection model could also be used to improve existing text generation models through adversarial training.
but they seem to average about 20%. This seems like a terrible record of failure for an AI tool that touts its precision.
That does seem pretty bad.
To play devil’s advocate for a moment, what systems were they using before implementing the AI tool? Were those systems better? Seems like a low bar to beat…
Is article doesn’t do a great job of explaining what the discovery actually is. The article linked in the article is a bit better:
Their findings modify Kirchhoff’s law, which has governed current flow in electrical circuits since 1845 and is a staple in high school students’ science classes. Unlike electrons, ions move due to both electric fields and diffusion, and the researchers determined that their movements at pore intersections are different from what was described in Kirchhoff’s law.
Prior to the study, ion movements were only described in the literature in one straight pore. Through this research, ion movement in a complex network of thousands of interconnected pores can be simulated and predicted in a few minutes.
Seems cool, but research is still in the early stages. I don’t think Super capacitors will be replacing lithium ion batteries any time soon.
Awesome. I always thought it was unfair that sharks get unlimited teeth while we are limited to two sets.
Interesting that the treatment is intravenous. I would have thought it would need to be injected locally. I wonder how they ensure that teeth grow only where there are missing teeth, or control what type of tooth grows at a given position?
Is this practical? To deliver a capsule to a specific location, you either need to wait for the orbital plane to align with the target, or have a fleet of capsules ready to go, each in a different orbit. Also, space is not the most hospitable place to store stuff.
If you really need stuff delivered ASAP, would it not be more practical to launch a suborbital rocket on demand?
If we’re talking about true AGI here, would that be small enough to fit on a hard drive or spread through the internet? Perhaps I am naive, but I feel as though any computer program which is as smart as (or smarter than) a human is going to be unwieldly large.
We got a huge percentage of humans who are struggling. Many under educated. We got slavery. We got wars. We got food issues.
I’m not convinced that these problems would be addressed by a smaller population. On average, people today are better educated, more peaceful, and better nourished than they were 100 or 500 years ago. I think this is mainly due to technological progress rather than population size.
I think asking why population needs to continue to rise?
I don’t think the population needs to rise, but there will definitely be problems if the population shrinks rapidly over just a few generations, one of the main ones being “who will take care of all the old people?”. Japan and Korea are already struggling with this, and other countries are not far behind.
Until a working prototype is built, I will be treating the field of warp drives (even sublight warp) with a healthy dose of skepticism. Glad people are working on it though.
This footage also showed how the latest iteration of Phoenix was trained using teleoperation by a human “trainer.” Using this data, the robot’s Carbon AI software could learn and replicate the process independently.
I wish they went into more detail on the training process. Can it learn just by watching, or do some action still need to be coded manually?
