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!

Not very active, but you can change that!
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?
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.”
There’s an entire book dedicated to answering your question: The World Without Us.
The Wikipedia article I linked summarizes a lot of the book, but I recommend reading it since the details are fascinating.
TL;DR:
