The submitted title is incorrect. The actual article title is "Pressure-induced high-temperature superconductivity retained at ambient". The abstract doesn't make the claim of superconductivity at room temperature at 1 ATM.

It looks like it lets you organize and comment on URL's? Is it of any use if you have content that isn't already on the web and isn't neatly tagged by URL? E.g. your own photos.

How about we recognize that SMS should be secure and make it so? If the FCC would require mobile providers to add crypto features to SMS that prevent spoofing, would it not be possible to do so?

I cannot imagine such a swindle being attempted in the US today, much less successfully. I feel a little sadness for that. There is something attractive about a place where so many crazy things are possible. Not that I would trade my existe

Not the OP but my kids (8,9) spend allowance on robux. Mostly it lets them build a big house for their friends to come over (in game) and play with them. They pair Roblox with video chat as their online hangout.

I am amazed in an article about bog oak no mention of dendrochronology. Scientists have been collecting and matching up tree rings from samples including especially bog oaks. This builds an unbroken chain of ring width measurements back

I think a negligible fraction of Roblox games are child created. The focus is either Roblox-created games like Bloxburg or indie adult-created games. Children (with their parent's credit card info) are the target consumers, not targe

I got some code related to VICE emulator. It looked pretty real, referring to concepts that make sense in the context of a C64 emulator, but the results said it was GPT not real code. It even had the correct GPL license matching that proj

Has anyone tried to stack and super-res the video frames? It is awfully small to see details but it seems like there might be a few clips where a multi-frame-based enhancement could do something.

I think there is a plausible mechanism for causation here. It adds to the expensiveness of children -- many smaller vehicles are not even compatible with the big car seats required, or with having more than two car seats in use. There is
