  • This was almost certainly an older style of MRI that didn't use superconductors. You could turn these off and on, but the strength of the magnetic field was much lower that what can be achieved with superconductors.

    I also looked up the wind down time and I was mistaken. It's a day long process to wind down and wind back up and MRI and do all of the testing and adjustments, but the loss of the magnetic field happens in a few hours. I edited my post.

  • Radiologist here. There are multiple safety zones (four to be precise) around the machine and extensive screening procedures are required to access the inner zones. The magnet of an MRI is always on and extremely strong. However, you need to be pretty close for it to pull a gun from your hands. Like, less than a few meters. That would be zone 4. He should never have been that close.

    The button he pressed is called a quench. It's for life threatening emergencies only. Think "patient trapped between the machine and a metal object." It vents the liquid helium used to keep it superconductive and basically destroys the machine, but the magnetic field dissipates in minutes. There is a way to wind the machine down without destroying it in situations that aren't life threatening or for servicing, but it takes hours for the magnetic field to dissipate and even longer to bring it back.

  • Screen durability and the distracting crease are the two biggest problems with foldables, so they are making a phone where a third of the screen is always unprotected, added an additional crease, and sharpened the radius of both creases. Hard pass for me (and most people), but this is more of a statement piece for their manufacturing and engineering prowess than a mass market product. Hopefully the advances they make will improve single fold devices.

  • I'm honestly surprised by this. They want him to self destruct on live television. If they make fun of him like they've been doing in every press release it will probably work.

    This will require Harris to still command the room and come across as professional and presidential though, which might be harder than it sounds when Trump can tell as many outrageous lies as he wants. I think she can do it, but it's a risk.

  • The uncle Sam image is clearly AI, but the pictures with people in "Swifties for Trump" shirts look real. But there is a "satire" tag on one of them...

    Either he believes the images are real, or he knows they are fake and is trying to meme a little. Either way he is a moron. If this forces Taylor's hand to either disavow Trump or just straight endorse Harris, he's cooked.

  • He was in a tough situation. We need to remember the extent of right wing vitriol and hate. Anyone who speaks out against Trump gets death threats. Their concerts would have had protestors outside. Continuing the tour could have been a safety risk for their fans. I'm not saying cancelling everything was the right move, but it's not as simple as "dick riding for Donald Trump."

  • They've been around awhile. During the pre-MAGA, "friends across the aisle" times I could see the value of creating a group that generally aligns with the Republican platform (low taxes, small government, etc.) but supports gay rights and pushes for progress on that issue from within the party.

    Today though, anti-LGBT sentiment is so strong within the party that it's hard to understand why the Log Cabin Republicans continue to exist, especially when they are openly shunned by the party.
