“There’s going to be a fundamental rebalancing in terms of how we think about indoor spaces," Allen says. "I think people won’t tolerate sick buildings. That era is over. Rightly so, and good riddance.”

Cornell University has agreed to pay $60 million and accept the Trump administration’s interpretation of civil rights laws in order to restore federal funding and end investigations into the Ivy League school.
The pivot. Wow that was fast.
I think it's idiotic to overreact to a couple of elections in blue states, but a few thoughts:
1) Scot Pressler, TPUSA, and a bunch of others have been working hard to register voters. I said it in 2022, and I've said it repeatedly since: our coalition is "lower propensity" and that means we have to do better at turning out voters than we have in the past.
2) We need to focus on the home front. The president has done a lot that has already paid off in lower interest rates and lower inflation, but we inherited a disaster from Joe Biden and Rome wasn't built in a day. We're going to keep on working to make a decent life affordable in this country, and that's the metric by which we'll ultimately be judged in 2026 and beyond.
3) The infighting is stupid. I care about my fellow citizens--particularly young Americans--being able to afford a decent life, I care about immigration and our sovereignty, and I care about establishing peace overseas so our resources can be focused at home. If you care about those things too, let's work together.
Boston wastewater for SARS-CoV-2 over the past month
“I think there’s a collective amnesia right now about COVID-19”
SARS-CoV-2 infections have been rising in the past month, and limited surveillance is hampering health strategies

Notable.
Congratulations to Majority Democrats @SpanbergerForVA and @MikieSherrill for their decisive victories to govern Virginia & New Jersey. They focused on affordability & they refused to be baited by tired MAGA tactics. I know they will lead with courage. @MajorityDems

Perspective
We need more of this. Excellent back-and-forth on the U.S. and China (and economics and history and tariffs), from people with different perspectives.

The situation is serious. Please pray for the families affected. I’m headed to Louisville now.

ARREST MADE in Harvard explosion
“Earlier this morning, acting on a tip received by law enforcement, investigators positively identified and arrested two suspects. The arrests were made by a multi-jurisdictional team that included the Harvard University Police Department, the Federal Bureau of Investigation, and local and state police departments.
There is no ongoing threat to public safety in connection with this incident or the individuals involved.”
The corruption is the constant.
"...Mr. Means may have violated federal conflict of interest laws by undertaking acts otherwise prohibited by law while retaining a financial stake in his company."
While serving as a White House advisor, @calleymeans helped craft the MAHA agenda to financially benefit his company, True Medicine Inc.
@SenAdamSchiff and I are demanding answers from @SecKennedy on why the White House encouraged this grift.
Not sure what’s going on or what changed, but the last 8 Acelas I’ve been on BOS <—> NYC have been delayed. Either I’m on a bad unlucky run, or something changed in last two months
Jake: “free trade w free people”
Trump: “we’ll give away our most advanced technology to our competitors and place tariffs on our allies”
Alt conclusion: 5% of companies are about to crush 95% of their competitors.
An M.I.T. study found that 95% of companies that had invested in A.I. tools were seeing zero return. It jibes with the emerging idea that generative A.I., “in its current incarnation, simply isn’t all it’s been cracked up to be,” @JohnCassidy writes. nyer.cm/FUZwzw8
.@NorahODonnell was excellent. She got the whole country to hear him say he thinks he has the authority to - and is prepared to - deploy the U.S. Army to American cities. Never thought I’d ever hear an American President say that in my lifetime. It’s was an important journalistic win to get him to say it directly - and in normal times would go down as an historic interview for what it exposed.
(She also caught him in a lie about the corrupt Binance pardon…)

UPDATE from Harvard:
thankfully no one was injured. The small section of the fourth-floor hallway where the explosion took place has been cleared and is fully operational.
There was no structural damage to the building, and all labs and equipment remain intact. Cleaning crews are on site to help ensure everything is ready for the beginning of the work week tomorrow.
HUPD’s investigation is active and ongoing. Yesterday afternoon HUPD released photos of two suspects seen fleeing from the building at the time of the incident. HUPD has confirmed there is no continued public safety threat, and it is safe to return to campus.
The Goldenson Building will be fully open and accessible to all who work in the building. HUPD will maintain an increased presence on the Longwood campus, which we hope will provide an added sense of comfort and security to our community.
If Satya just announced MSFT already has more GPUs in-hand than it can even deploy, and Andy announced AMZN is using 1M of its own chips at its massive AI cluster, why is NVDA stock still so high?
About a year ago, this site near South Bend, Indiana was just cornfields. Today, it’s 1 of our U.S. data centers powering Project Rainier – one of the world’s largest AI compute clusters, built in collaboration with @AnthropicAI.
It is 70% larger than any AI computing platform in #AWS history, with nearly 500K Trainium2 chips, and is now fully operational with Anthropic actively using it to train and run inference for its industry-leading AI model, Claude (providing 5X+ the compute they used to train their previous AI models). We expect Claude to be on more than 1 million Trainium2 chips by the end of year.
Will help enable the next generation of AI innovation as we further extend our infrastructure leadership. aboutamazon.com/news/aws/aws…
