  • Three-year-old girl is 'scarred for life' after she was left with chemical burns...

    Article was trying to make a good point about what's commonly referred to as 'black henna.' It got the true culprit, para-phenylenediamine, right, but not much else technically. This was NOT a chemical burn, rather it was an allergic reaction perfectly analogous to a strong reaction to poison ivy/oak/etc. Although it's conceivable to scratch enough to produce permanent scarring that is relatively rare. The child most likely is NOT 'scarred for life.' She likely has residual hyper pigmentation which will fade over some months on its own.

    Para-phenylenediamine is the chemical basis for most 'permanent' hair dyes, regardless of their color. The exceptions are temporary dyes that are fully removed with the next washing (eg. your kid wants blue hair for the day), semipermanent wash in colors (most famously the old 'Grecian Formula') and henna used alone. The temporary dyes are free of PPD; their only risk is to one's fashion sense. The semipermanent ones classically worked by gradually adding lead acetate to your hair. Used for decades and blessed as safe by the FDA as recently as 1980, lead acetate has been banned by the Trump FDA in the last month or so. Its former products have switched to other chemicals, most often bismuth citrate, but a quick internet search suggests the alternatives don't work as well. This dermatologist just learned of that ban today. Henna is a plant based 'natural' product and it permanently colors the hair without washing out. However, by itself, it only produces one color, famously the trademark color of that natural blond, Lucille Ball!

    PPD is one of the more common causes of allergic contact dermatitis and can produce strong reactions. It's only a problem as a liquid, until it's set. Once set and dyed the colored hair doesn't cause allergic reactions. Allergic contact dermatitis to henna has been reported, but is rare. Dying your hair with henna works well — if you want to look like Lucy. Henna has long been used to temporarily stain the skin (a 'temporary tattoo'). Used alone it gives a reddish brown color, which isn't very dark and wears off fairly soon. Adulterating 'henna' with PPD produces a darker color which lasts longer, which those wanting a 'temporary tattoo' prefer... unless they become allergic and this happens. 'Dark Henna' really isn't a different form of henna, it's henna PLUS dark (PPD) and in many cases most of color is from PPD. As PPD allergies are common, reactions like this are common to dermatologists. They're normally treated like similar amounts of poison ivy rashes, combined with avoiding PPD in the future. Which for many eventually means embracing their eventually grey hair.

  • “Sun in a box” [in theory] Stores Renewable Energy & Delivers It on Demand

    Yup, hot graphite is bad stuff to have around O2. Burned tons of the stuff at Chernobyl too, IIRC. It’s an engineering problem to keep the O2 out and certainly isn’t a unique problem on Earth. Simple on the moon. At least if this burns here there’s no radioactivity to deal with. The resulting pollution would be CO2, some CO, and rock dust. Need air filters or respirators in the smoke, just a broom outside it.

    What’s new is they’ve developed a way to store heat energy at much higher temperatures than previously possible, which makes the process much more efficient. And are making the bulky part of it out of rock cheap raw materials. There are engineering issues to work out yet, although they appear to have solved some, Some are mentioned up thread. Having your working material turn solid during maintenance is an issue this shares with the liquid salt thorium reactors, whose proponents don’t seem to think of that as a major problem. If the eventual solutions don’t add too much cost this has the potential to scale up better than an other mass energy storage proposed yet. If so there’s bound to be some practical use for it even if greenie dreams are worthless.

    Halley’s orbit provided its worst view in 5k years IIRC the last time whereas prior visit was glorious. I did see it, but it took a friend to show it with a 16” telescope.

    >If released from its container, molten silicon will react with oxygen rather dramatically.

    Their container, at least the inner layer contacting the molten silicon, is all graphite. That will also burn dramatically. Keeping atmospheric O2 out of the system would be a key engineering requirement.

    Using 'renewable energy' on earth is a dumb liberal pipe dream, but this might make sense for a moon base. Plenty of real estate to site a solar mirror site there without killing any birds or turtles. Collect energy for two weeks, store half in molten silicon and recoup that the next two weeks. May need to import the graphite and some of the other working parts from the earth, but the silicon can be sourced from moon itself, saving megabucks. And no O2 worries with the lunar vacuum. The moon there has no hydropower and no fossil fuels (and wouldn't want to waste O2 on latter even if they existed) so the main alternative to solar would be nuclear, which has its own cost issues.

    The federal false claims act and RICO both allow triple damages to take back what the Lefty Green elite have stolen and fraudulent academics have misrepresented over the years. Defund the left and refund the country.

    They’ll try to count all the illegals and everyone else they can invent on the next census. How about ruling that the CA census results are completely unbelievable, and unauditable so award them the number of House seats they deserve for certain, one. Let them all have Mad Maxine! Constitution specifies they must have two Senate seats. So 3 electoral votes for the state.

    >No one can view the Ark except for the guardian monk, who is confined to the chapel looking after the golden crate until his death.

    Have seen multiple shows on this claim, all much the same. All add that said monk can’t be interviewed and no one can gointo the Church. Which are flagrantly impossible over generational time scales. When the old monk dies who picks the next one? Who trains him? How do they know the old one died? Who brings out his body? Who maintains the building? One monk can only do so much. How is food delivered? How, do they know when randomly wearing out items like robes need replacing. There has to be some communication between the monk and the bureaucracy of the Ethiopian church that maintains him. But the shows never ask those questions.

    >It’s an internal water.

    Saith Bully Putin. But the Sea can't be internal water just of Russia when much of it borders part of what, even Putin admits, is still part of the the Ukraine. International law says the Kerch Strait is a strait and navigation through it must be permitted. So send through a ship named for a Nobel Peace Laureate, laden with media who thinks that prize was deserved, and backed by the real politic strength of a President who knows better. Would Putin arrest the CNN embeds? Would he sink a scow named for Obama? He understands PR to well to do either.

    And if Putin wants to sail up Niagara falls he's free to try it, but should be aware our environmentalist lawyers will quick to sue him for any damages done to them. And the locks around the falls are clearly not natural straits.

    Time for the US Navy to send a ship to make an unscheduled port call to those 'blockaded' Ukranian ports. But we need to send the ship that will send the correct message. We need to divert this one from its usual duties. And be sure to embed a full CNN news team to record all its received honors.

    Intentionally blocked by the 24th amendment back in the early '60s. I understand why it was enacted, but I'm still not sure it was the correct fix for that problem. At least we cannot blame this one on the courts.

    Add to inventory fireproof remote sensors to say how long is enough, and a periscope. Consider possibility of debris falling over your exit in your design. Dom’t waste O2 or CO2 capacity using generator while air tightened during the fire, use batteries then.

    Fireproof shelter 20 feet under won’t do much good unless also have an air lock with adequate O2 and CO2 scubber supplies. Otherwise they’ll merely represent self-entombment.

  • California’s Typhus Surge Is Linked to Fleas, Feces, and Bad Economic Policies

    JohnBovenmyer to InABunkerUnderSF

    Iirc the variety of Typhus associated rat’s fleas historically kills relative,y small numbers of prople. Its cousin, spread by human body lice, is the real big fast killer. Unlike head or crab lice, which live on the hairs of humans, body lice actually live on the unwashed clothing of people. That the people inside unwashed clothing are often also unwashed is merely coincidental. CA hasn’t reached that tipping point — yet — but current policies are pushing them in that direction. Where the traditional fixes will be forced up9n them: round up all the problematic people into camps, burn all their clothing, dust them all down with DDT powder. Sufficiently terrified libs can and will employ the first two measures, even while being accused of liberal apostasy by those libs further removed from the reckoning. But the third will stymy them. Their favorite mass killer and their once favorite boogeyman, Rachel Carson and Trickey Dick Nixon, conspired to rid us of DDT. Trump needs to push lib BPs even higher and restart its production!
