Those concerns are for unrealistically high doses though. The last sentence of the abstract you linked:

In conclusion, based on the totality of currently available scientific evidence, the present review does not support the presumption that fluoride should be assessed as a human developmental neurotoxicant at the current exposure levels in Europe.

Calling concerns about the safety of fluoridated water “founded” is a bit of a stretch.

It’s the editorial board that makes endorsements. The opinions section is completely separate from the news section - the news reporters don’t contribute to the editorial decisions or endorsements.

I don’t know what to call them, kind of an in between between what you would call fast food and what you would expect from a “slow” fancier restaurant

Fast casual? Typical chains considered to be “fast casual” are Chipotle and Five Guys. A local taco/burrito/burger/sandwich place would probably fall in that category.

The yield is small enough that it isn’t a threat to the soldiers launching it. Still, I wouldn’t want to be the one tasked with firing it.

Yeah, it’s quieter so there’s fewer overall responses even in “popular” posts, but it doesn’t feel like anything gets ignored. If a post is interesting, you’ll get at least a few replies even if it takes a few days.

That part is kinda nice - the lower turnover on the “front page” means you’ll have people reading and commenting on discussions for days. If you reply to a 1-day old post on Reddit the only person who might see/reply to you is the person you replied to.

The US Department of Energy…

As annoying as it is to lug a bag around and find room for it, I much prefer this to checking it. There’s the small but nonzero chance your bag doesn’t make it to your destination, plus the added time waiting at baggage return.

I will run this thing until it dies.

Good luck with that. My 2011 MacBook Pro still works. I’m pretty sure it’ll outlive me.

It’s already been published. But it’s superconducting at 10 K. This is a new high temperature record, but pretty far from room temperature.

They’ve been doing studies of what would be required for ignition for a while, but have never demonstrated ignition using the Z machine.

If they did have ignition, there’s no way they would’ve let LLNL claim to be first and enjoy all the media attention.

Nah, the Z machine never achieved ignition. That doesn’t mean it’s not a really cool facility though!

If they need to raise prices by 18% to pay their workers, then they need to actually raise the prices on the menu. Right now this is just bait and switch, it’s dishonest and possibly illegal depending on the location.

The article is reporting on a published journal article. Surely that’s a good start?

Seek by iNaturalist

The app uses AI to identify the species of plants, animals, insects and fungi. In video mode you scan around something you want to ID as the AI narrows it down to the species. Then you can take a pic. The app keeps track of each unique species you’ve found (along with your photo of it). There’s also badges and achievements for identifying different numbers of species, if you want to gamify your nature sightseeing.

It’s basically real life Pokémon. Oh and it’s completely free.

Having YouTube premium means I can use it on any platform. I can use YouTube music on my phone with CarPlay and listen while driving, use the built-in YouTube app that hotel TVs have when I travel for work, watch things on my work computer, on my phone, or using my PS5.

You can use the YouTube music app with a standard (free) YouTube account, at least on iOS. But the audio only keeps playing in the background if you pay for YouTube music. And I think you can’t download music to play offline.

For what it’s worth, YouTube Premium ($14/ month) includes YouTube music and removes ads for YouTube.

Nah, that was ARPANET. The internet (www) was invented because particle physicists were too lazy to carry magnetic tapes with experimental data around CERN.

With betavoltaics it’s more a matter of physics than lack of engineering refinement. Even assuming 100% efficiency, you would need something like 250 gallons (1000 liters) of tritium gas at atmospheric pressure to power a 100 Watt lightbulb.

Nuclear reactors, however, absolutely should be supplying a larger fraction of our electrical grid. Traditional, large reactor facilities have such a high cost and long timescale for permitting/construction that it’s difficult to get newer, more modern reactors built in the US. There are some exciting developments in small, modular reactors that would sidestep these issues. I believe a few designs are in the process of being built for full scale testing.

If you’re interested in a particular charity organization, you can look them up on Charity Navigator. They pull information from the charity’s IRS filings as well as their website to rate various aspects. They give a breakdown of things like the fraction of funds spent on administrative costs, privacy policies, fundraising efficiency, etc.

They also provide the contact information and website for the charity. This way you know you’re donating to the actual charity and not a scammer impersonating them.

Betavoltaic devices are exactly what you’re describing. They convert beta radiation (energetic electrons) into electricity in the same way that photovoltaic cells (solar panels) convert photons into electricity. You can create a nuclear battery by putting some radioactive material that decays via beta emission in one of these.

The downside of these devices is that they generate very little power. It takes a dangerous amount of radioactive material to generate the power needed for say a phone or laptop. Commercial betavoltaic devices generate ~tens of microwatts. They’re useful if you need a low power battery somewhere that you don’t want to replace, like in a remote sensor.
