  1. Don't let the perfect be the enemy of the good on Researchers Claim Success In Removing HIV From Living Cells (nature.com) · · Score: 4, Insightful

    Gotta disagree with you saying that 88% isn't good enough.

    1) If current measures are reducing transmission of HIV to R values (new cases per existing case) of something like 1.2 or lower, this could bring it below the threshold of being able to increase in numbers and thus speed eradication.

    2) If 88% of CURRENT HIV+ are completely cured, drugs and resources saved can be concentrated on the remaining 12%, thus reducing R values even further, speeding eradication.

    3) 88% cure rate is a pretty massive reduction in human suffering, isn't it?

    I'm not claiming that the journalists got it right, but there is such a thing as an anti-reflective coating. It's routinely put on glasses to reduce reflections.

    At least on the face of it, it's possible that the metallic glass can form an anti-reflective coating on the windows.

    Seems like the broadcasters are shooting themselves in the foot! If you can't record, you can't store up a bunch of shows to watch later.

    This means that people won't watch broadcast at all, but rather will default to streaming services for convenience of watching when they want.

    Seems like they've got the wrong solution. Instead of "do not record", it should be "do not copy the recording you make to other media"--which, guess what, is what most people do anyway with their DVRs.

  7. The problem is, fusion probably isn't worth doing on Cold Fusion and the Reputation Trap (aeon.co) · · Score: 1

    At least DT fusion of thermal plasmas that are magnetically confined.

    Most of the energy comes out as fast neutrons or gammas, and getting energy from those requires a large thermal conversion plant (steam generator).

    Check out this link, where it is argued that direct electric conversion technologies will win on cost vs. thermal conversion plants:

    https://matter2energy.wordpres...

    Basically, fusion will always fail on economics. Unless someone comes up with a way to do fusion of species that produce energetic charged particles, which will allow direct conversion. And to do that, you probably need a non-equilibrium plasma, because equilibrium thermal plasmas that aren't optically dense: someone proved these cool faster via bremsstrahlung than they self-heat via fusions. And non-equilibrium plasmas, those are hard to sustain--nature abhors moving fluids that are of different velocities (or more generally, whose distributions are non-Maxwellian).

    After learning these things I greatly fear that economical fusion just isn't going to happen--don't get me wrong, I'd love for someone to succeed at it and provide clean cheap energy--but I think the capital investment will always make fusion more expensive than alternatives.

  8. Real power generation doesn't need belief on Cold Fusion and the Reputation Trap (aeon.co) · · Score: 5, Insightful

    If Rossi's or anyone's claim that cold fusion (or some other power generation technique) worked was real, then they don't need anyone to believe them. They could just sell power and bootstrap themselves to millions/billions.

    For example, if I could produce a few MW of electricity cheap, with a compact form factor, I'd just go to Hawaii (which has really expensive electricity) and undercut the price of electricity there and sell the power to a datacenter or a high rise building. With the profits, I could bootstrap and make more power generators, and displace more competing capacity.

    And with generators that were powering MWs of buildings/datacenters, with no visible fuel inputs other than deuterium, I think credibility would soon be a non-issue.

    >You sound like all your knowledge of opioid treatment comes exclusively from anti-drug propaganda sources. It sure as hell didn't come from the medical community.

    Actually, the knowledge comes from my friend, who suffers from chronic pain, and who quit opiods cold turkey and now lives with the pain (though it's less now), the depression, and is recovering mentally slowly. He's been doing heavy research on the effects opiod use has on people, as he tries to find his way back to relative mental normalcy.

    He was on opiods for years and would withdraw peroidically so he could keep the dose he was taking small and still be effective. His pain doctors complimented him on how well he managed his opiod use. It still became problematic for him and now he's quit for good, and quitting has been a painful struggle for him.

    Believe it or not, I'm actually pro legalization for most drugs. I don't think the drug war has done much good or been successful.

    That said, opiods are dangerous, should be legal, and should be used where compassionately necessary, but it'd be WAY better if this new treatment would work instead. I'd rather see people not suffering from pain OR from the problems opiods can cause.

    > Well you're into that whole drug war propaganda thing where you believe everyone prescribed some Vicodin for a toothache is shooting up heroin with dirty needles while homeless in an alley a few months later.

    Actually, I was very careful what I said. I said "too long". I said "long term use". Opiods seem pretty OK for people who are using them for short term acute pain. It's chronic pain sufferers who are more at risk, and I really hope this new treatment works to completely kill their pain. I also hope it can replace standard opiod treatment for acute pain. It'd work better and it would be safer.

    That's why this story is so cool.

    There's a good reason why doctors are hostile to analgesics. They can cause damage that lasts far longer than the acute pain, and can cause effects in the long term that are worse than the chronic pain, in many cases.

    For many cases of chronic pain, the relatively harmless stuff like NSAIDs, aspirin, and acetaminophen don't really work well enough, and in high doses all of these are toxic. So out come the opiates, however, opiates quickly induce tolerance so larger and larger doses are required. And the tolerance becomes addiction, and the brain starts getting re-wired. Not to mention the side effects of opiates, which aren't all that nice either.

    It can take *years* for a brain re-wired by long term use of opiates can return to "sort of" normal, if ever. And the return to normal has nasty psychological effects, such as depression, OCD-like symptoms, suicidal tendencies, and an inability to be happy or experience joy.

    It's much more than "moral panic" over opiates. The drugs are frankly dangerous, and even with the very best management practices, they will spin out of control if a person is on them too long.

    I'd only want to be on large amounts of opiates if I were terminally ill.

    Citrus greening is rampant in Florida, and many areas worldwide, but is spreading somewhat slower in California because citrus areas tend to be separated by ridges of hills.

  23. AI as composition of stack of narrow intelligence on Is AI Development Moving In the Wrong Direction? (hackaday.com) · · Score: 3, Informative

    Hello,

        Interesting post. I just wanted to make a point about the existence of general intelligence: it turns out that the human brain is actually a stack of many "special purpose" computational systems. That doesn't mean that there isn't a general intelligence portion as well, but we're DEFINITELY composed, at least to some degree, of stacks of special skills.

        Examples:
    1) Vision and object recognition. There's a whole subsystem of the brain dedicated to decoding light signals into a representation your consciousness can use. There's even a special subsystem for recognizing faces--they even know its location in the brain.

    2) Audio: similar to vision, there's specialized decoding brain circuits.

    Those are the two biggies, but we also have special hardware for processing/controlling speech, spatial reasoning, body control, and others. What's more, there are people who have *developed* special purpose brain circuitry for playing the violin, for example, and savant-like mathematical computation. For people who have done that, it is as easy to do a square root to N digits as it is for you and me to walk.

    Because of that, it's NOT clear to me that a general purpose intelligence can be made without assembling a sufficient number of special-purpose intelligence. It's NOT clear to me, in fact, that there are unknown forms of special purpose intelligence that humans are lacking that wouldn't transform our general intelligence. (People are prone to making certain logical errors, even the brightest of us, because of in-born holes in our mentalities!)

    A dolphin might look at us as crippled mentalities because we can't construct a spatial model of our surroundings from sound, for example. What other mental abilities COULD exist, that we don't have, that could expand our mental potential in outrageously powerful ways? People typically aren't able to fork their consciousnesses into solving two problems at once independently, there's one I'd like!

    But the point I'm trying to make is that the stacking approach might be NECESSARY to compose a mind capable of general intelligence that we'd recognize. It might not need ALL our special purpose skills, but it's not obvious to me that a composition isn't necessary.
