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…

Is that actually the church’s stance? Like, has the pope ever said this?
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.
It still is a blurry orange ball, where the orange is the location of radio wave emission. The team did a new image where they measured the polarization of the light, which is the result of strong magnetic fields where the light was emitted. The lines are drawn over the image to depict the polarization orientation of the light as a function of location.
I want to be clear that this is an incredible feat, both the fact that they can produce an image of a black hole from the center of our galaxy AND determine the polarization of the light. But they don’t have a super crisp image of matter swirling into a black hole.
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.
Settle down, Jayden
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!
The article is reporting on a published journal article. Surely that’s a good start?
Where did you hear that? CFCs can linger in the atmosphere for 50-100 years, so recovery is a slow process. It took more than a decade after the Montreal Protocol went into effect before the hole in the ozone layer stopped growing. Additionally, different parts of the ozone layer will recover at different rates:
Lots of doom and gloom in the comments here. As the article describes, the hole in the ozone layer varies in size over time. It is slowly recovering, but the annual variability means it sometimes is larger than before.
The variability of the size of the ozone hole is largely determined by the strength of a strong wind band that flows around the Antarctic area. This strong wind band is a direct consequence of Earth’s rotation and the strong temperature differences between polar and moderate latitudes.
If the band of wind is strong, it acts like a barrier: air masses between polar and temperate latitudes can no longer be exchanged. The air masses then remain isolated over the polar latitudes and cool down during the winter.
Although it may be too early to discuss the reasons behind the current ozone concentrations, some researchers speculate that this year’s unusual ozone patterns could be associated with the eruption of the Hunga Tonga-Hunga Ha’apai in January 2022.
And
Claus concludes, “Based on the Montreal Protocol and the decrease of anthropogenic ozone-depleting substances, scientists currently predict that the global ozone layer will reach its normal state again by around 2050.”

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.
