BREAKING: The U.S. House of Representatives just advanced a bill to reinstate the China Initiative, which would devastate the lives of so many Asian American scholars in our country! See @AASForumOrg statement with @StopAAPIHate & @AAAJ_AAJC aasforum.org/2024/09/11/stop…

Blackthorne: you tell them this is some of the most small-minded and shallow feedback i've ever received and i'm NOT adding a section about that Mariko: the Anjin says he would like to thank two anonymous reviewers, whose thoughtful feedback greatly improved this article.

NEW: We have the University of Rochester's 124-page investigation report. A committee of external reviewers made an unequivocal finding: Dias falsified and fabricated data, and he committed serial plagiarism—including in his 2020 NSF proposal. nature.com/articles/d41586-0…

One year ago today, Ranga Dias published an extraordinary claim: a room temperature superconductor at moderate pressure. The paper was retracted, amid allegations of scientific misconduct. For Nature’s news team, I investigated how it all transpired. nature.com/articles/d41586-0…

Interested in 3D magnetic nanostructures? We studied the magnetic switching behavior of tetrapods (fabricated by FEBID, see image) experimentally and numerically. Here is the arXiv link if you want to learn more: arxiv.org/abs/2402.17594 – at Hamburg, Germany

Paper's been around on arXiv for two years. 0 citations. Give it a rest.
"Global Room-Temperature Superconductivity in Graphite", peer reviewed and published in Applied Quantum Materials, presents strong evidence for T=300K superconductivity in cleaved, highly oriented pyrolytic graphite, with an underlying physical theory. Check out the data (1/4):

Members of the U.S. Congress, of Congressional Asian Pacific American Caucus @CAPAC, wrote a letter to urge congressional leadership to halt the potential reinstatement of the China Initiative. Here is the letter. meng.house.gov/sites/evo-sub… Please kindly repost.

This exciting paper shows AI design of materials, robotic synthesis. 10s of new compounds in 17 days. But did they? This paper has very serious problems in materials characterisation. In my view it should never have got near publication. Hold on tight let's take a look 😱
🚀 Exciting News! Our A-Lab has revolutionized inorganic materials discovery! Combining ab-initio calculations, historical data from literature, and robotic testing, we're rapidly uncovering new compounds. 🤖 nature.com/articles/s41586-0…

In 2017 when neo nazis marched in Charlotteville yielding Tikki torches, spokespeople at every university raced to denounce them. My own chancellor wrote: “There was only one side that provoked the hate-fueled violence…” and “We cannot allow our institutions of higher learning to become centers for ideologies repugnant to everything our nation stands for.” On Saturday Oct 7 2023, I woke up to the biggest slaughter of civilian Jews since the holocaust. The atrocities were plainly documented by Hamas terrorists in snuff porn cascading through my twitter feed, a modern day pogrom. While anti-Israel bias is a well known problem on university campuses, I somewhat naively expected the administration (of any university) to unequivocally disavow this violence and recognize the victims and aggressors as such, just as they had opined on every major event in recent memory. With the facts so starkly laid out, how could they say anything else? Days passed. Governments worldwide, celebrities, and even major league sports released perfectly sensitive and appropriate statements. Meanwhile, universities worked in lockstep, just as they did 3 years ago to send your kids to zoom university after the tuition check cleared, and they posted identical mealy mouthed garbage essentially saying that “there are fine people on both sides.” No mention of Israel, Jews, or Hamas. What was stopping them from making an unequivocal statement that this was a terrorist slaughter targeting civilian Jews? Are they scared of what a fraction of their students would do? Are they so captured that they think that these atrocities are justified? Do they have intel that Iran would hack them if they said the wrong thing? If it is the latter, please send me an e-mail; I promise I won’t post it on twitter. But it is almost certainly the former two reasons. Let me be perfectly clear. As a Jew in urban California, I am not likely to encounter the Charlottsville flavor of nazi. Those people are shunned from society and the individuals at that rally had lost their job at the hotdog stand by Monday morning. But I am surrounded by modern day Nazis who fill the halls and administration of academia, who celebrate in the streets of major western cities before the blood of the pogrom is dry, who sit on the city council of the city where I live. Their propagandized safe spaces have taught them that the slaughter of Jews is acceptable, if there is some justification, just like the Germans in WW2. People of the same ideology were operating in Israel on the morning of Simchat Torah yielding machine guns (not Tikki torches). The only missing piece in the United States is a charismatic leader, and we are just one octogenarian election cycle away from that happening. I do not think that universities should opine on every issue; I actually think they should stay all the way out of making political statements to not tip the scales of free speech. But the fact of the matter is that they have been opining and picking sides for years, and it makes a statement when they suddenly choose to stop doing this.

My department is hiring a tenure track professor this year and almost certainly hiring another one next year, growing our physics program. Watch this space for a job posting! EKU has incredible resources for a PUI, with great optics and nuclear instrumentation labs.

We'll be updating our story shortly. Notably, all authors but Dias agreed to retract. nature.com/articles/d41586-0…

It's over #LK99
I was able to closely mimic the “levitation” behavior of LK-99 with a ferromagnetic sample. For comparison, see the original LK-99 video in the tweet below.

With a great deal of sadness, we now believe that the game is over. LK99 is NOT a superconductor, not even at room temperatures (or at very low temperatures). It is a very highly resistive poor quality material. Period. No point in fighting with the truth. Data have spoken.

Suppose we take the original resistivity data of LK99 at face value. The plot from arXiv 2307.12037 is pasted below with digitized resistivity values at characteristic temperatures, in more conventional units for metals, written to the right.
