  • Courtesy of Roger Ailes and the invention of political talk radio, The United States was the breeding ground for media manipulation tactics that later arrived in Europe, and those have been most heavily utilized by right-wing actors – think Sky News/The Daily Mail/The Sun in the UK, or instance. When you poll most people about what they want out of government here in the US, they tend to be in alignment with “liberal” values in the US or center-left parties in Europe, but when you ask them if they support implementations of those values by name (i.e., “Social Security” or “Medicaid” or “food stamps” instead of just asking “should the government help needy people stay fed and healthy?” people who consume right-wing media suddenly flip to be against those policies, because they are brainwashed by their media diet to oppose them even though in principle they express support for them.

    Bottom line, after almost forty years of Rush Limbaugh and his ilk and thirty years of Fox News deliberately manipulating the American right to become hateful and reactionary in spite of their own natural impulses, the gap between left and right has become incredibly difficult to bridge in any meaningful way. IMO, the only hope for reconciliation is to push those extreme voices out of the mainstream in order to limit their ability to influence the gullible, and there’s just not many viable mechanisms to do that.


  • Any time you see perovskite-based cells mentioned, you can assume for the time being that it’s just R&D. Perovskites are cool materials that open up a lot of neat possibilities, like cheaply inkjet-printing PV cells, but they have fundamental durability issues in the real world. When exposed to water, oxygen, and UV light, the perovskite crystals break down fairly rapidly.

    That’s not to say that the tech can’t be made to work – at least one lab team has developed cells with longevity similar to silicon PVs – but somebody’s going to have to come up with an approach that solves for performance, longevity, and manufacturability all at once, and that hasn’t happened yet. I imagine that when they do, that will be front-and-center in the press release, rather than just an efficiency metric.



  • This is actually becoming somewhat commonplace. For example, in many cutting-edge cancer therapies, blood is drawn from the patient, processed in tissue-culture suites on site to extract the patient’s immune cells and sensitize them to some marker expressed by their specific cancer cells, and then the modified immune cells are returned to the patient room and transfused back into their bodies. It’s not cheap per se but it’s something that most top-tier cancer centers can do, and to do the similar process of extracting stem cells, inducing them to transform into pancreatic islet cells, and transplanting those into the patient’s pancreas isn’t that big of a jump – and it’d be cheaper than a lifetime of insulin in any case. It also points the way towards treating other kinds of organ failure without the risk of rejection, too.


  • My two favorite things about this car are the split windscreen (actually not an unreasonable choice at the time, as laminated safety glass has to be custom-molded for regular car windscreens, and the tooling for that would have been cost-prohibitive for a projected run that might not reach double digits) and the backwards-facing NACA ducts arranged as extractors for airflow through the radiators (they don’t actually work in reverse like that, but I guess in 1993 a low-volume manufacturer was probably doing aerodynamics by seat of their pants).



  • Data center cooling towers can be closed- or open-loop, and even operate in a hybrid mode depending on demand and air temps/humidity. Problem is, the places where open-loop evaporative cooling works best are arid, low-humidity regions where water is a scarce resource to start.

    On the other hand, several of the FAANGS are building datacenters right now in my area, where we’re in the watershed of the largest river in the country, it’s regularly humid and rainy, any water used in a given process is either treated and released back into the river, or fairly quickly condenses back out of the atmosphere in the form of rain somewhere a few hundred miles further east (where it will eventually collect back into the same river). The only way that water is “wasted” in this environment has to do with the resources used to treat and distribute it. However, because it’s often hot and humid around here, open loop cooling isn’t as effective, and it’s more common to see closed-loop systems.

    Bottom line, though, I think the siting of water-intensive industries in water-poor parts of the country is a governmental failure, first and foremost. States like Arizona in particular have a long history of planning as though they aren’t in a dry desert that has to share its only renewable water resource with two other states, and offering utility incentives to potential employers that treat that resource as if it’s infinite. A government that was focused on the long-term viability of the state as a place to live rather than on short-term wins that politicians can campaign on wouldn’t be making those concessions.

    The Wikipedia article for these little monsters describes the males aggressively fighting over females mid-mating, to the point of killing some as they attempt to tear them away from one another, and then squeezing the eggs out of their dead bodies to fertilize them… Gonna guess it’s the same one.

    I live in an old, once-redlined streetcar suburb, and my folks are about a half hour away in a new, nearly-exurban tract home development. They love to see their grandson and are happy to babysit him when my wife and I want a date night, but we’ve just about stopped taking them up on that offer because every restaurant in a reasonable distance from their neighborhood is some mediocre, mid-market national chain that’s utterly devoid of charm, serving plates that have been ruthlessly value-engineered to minimize the need for specialized equipment or skilled talent in the kitchen. The area is quiet, I guess, and I’m sure the land was cheap, but there’s no there there.



  • I’m a lab planner, and sometimes getting researchers to describe what sort of containment device they need for a given process is like pulling teeth.

    • Chemical fume hood? That’s a hood.
    • Class II, Type B2 BSC? Also a hood.
    • Class II, Type A2 BSC? Believe it not, hood.
    • Laminar flow bench? Yep, that’s a hood too.
    • PCR dead air box? Somehow also a hood.

    Like, surely you’re not doing BSL-2 work in a LAF? Please tell me you’re not doing that.
