They have quantitative magnetization-versus-temperature data taken using a PPMS (an automated physical property measurement system). It shows strong evidence of some kind of diamagnetic transition at ~ 320K. It seems very likely now that th

Yeah it looks to me like either a replication failure or even evidence AGAINST a superconducting phase. A superconductor's resistance curve is supposed to show a sharp drop to zero at the transition temperature. If it's a dirty in

They theoretically agree that the material's properties could be nice for making some kind of superconductor, but present no clear indication that it would/should be a room temperature superconductor. The critical temperature depe

Don't get too excited --- theorists have predicted nine of the last five physics breakthroughs (pace Paul Samuelson).

Looking through report issued by Stanford's scientific panel, it seems quite clear that (i) Tessier-Lavigne and/or people in his group have been very naughty indeed, and (ii) most of their image manipulations might have escaped no

There are tons of everyday use-cases where it's preferable to sacrifice fraud protection to achieve instantaneous money transfer. Credit card companies have normalized using credit cards (with their attendant fees) for all sorts of sma

In my country (Singapore), the instant payments system was rolled out in 2017 but took several years to get traction. The pandemic seems to have marked a turning point: it's now accepted pretty much everywhere, and it's great. You

Reminder that Google killed Google Reader, which was a wonderful front-end to the web, to try to funnel users toward Google+. As everyone knows, Google+ never gained the traction Google wanted, but it did have a decent commenting/discu

Of course it doesn't contain the word TikTok. Legislation can't single out an individual company or person, it wouldn't pass legal muster. So you write it in general terms, and ta-da! The ban hammer that you wanted to apply t

Scientists used to use anagrams to register scientific discoveries without revealing them. Hooke registered his law of elastic extension using the letters "ceiiinosssttuv”, which he later revealed to unscramble into "ut tensio, si
