1/ New rare earth restrictions mark escalation in China’s weaponization of interdependence — adopting US extraterritorial permission structures. This is not just an export ban but regulated how global firms use Chinese equipment and material.

Terrible on its own terms, and also poisoning the waters in congress for any kind of bipartisan deal on transmission/permitting issues.

SCOOP: The Bureau of Land Management says the largest solar project in Nevada — the Esmeralda 7 mega-farm — has been canceled

The news was quietly dropped via a sudden website update with no public word from any of the companies involved or a statement from the agency

In my book Partial Hegemony, I wrote about the Oil-For-Security deals that the USA has extended to petrostates in the Persian Gulf for decades. Any state threatening those petrostates, even Israel, risks American ire.

🚨NEW PAPER🚨
We all know the 2022 energy price shock fueled the cost of living crisis. It also caused a profit bonanza for the very rich. We show the US reaped the largest profits ($377bn) of any country. 50% went to the richest 1%, only 1% to the bottom 50%. A🧵 www.sciencedirect.com/science/arti...
River or sankey diagram showing the allocation of profits from global oil and gas companies to quantiles of the US wealth size distribution via financial system intermediaries, such as asset managers, and categories of ultimate beneficiaries, such as business owners, pension funds and shareholders in listed companies. The scale is hundreds of billions of US dollars, and ultimately 50.4% of profits reaching the US personal wealth distribution go to the richest 1% of households.

Academics! Take comfort. However badly your academic year is going, it's still probably going better than Bill Belichick's.

Bill Belichick's move to college football has gone spectacularly wrong. UNC is last in the ACC in offense; last in sacks; last in 3rd down offense; and been outscored by P4 opponents (all of them unranked teams) 120-33. Why has it go so wrong? Start with this: www.nytimes.com/athletic/668...
Where did Bill Belichick’s UNC roster go wrong? What we’re hearing entering Week 6
At North Carolina, six-time Super Bowl winner Bill Belichick appears to have simply assembled a poor roster.

International student arrivals to the US dropped 19% this year, the biggest drop on record aside from the 2020 pandemic low.
upshot.nytimes.com
The decline is occurring as the Trump administration has delayed visa processing, instituted travel bans or restrictions for 19 countries, threatened to deport international students for pro-Palestinian speech, and heightened the vetting of student visa applicants.

Happy Anniversary of the Battle of Cable Street, to all decent people.
Plaque "THE BATTLE OF CABLE STREET
The people of East London rallied to Cable Street on the 4th October 1936 and forced back the march of the fascist
Oswald Mosley and his Blackshirts through the streets of the East End.

Sure, they can break. Like all electrical equipment, they can short in spectacular ways. But explode like a refinery? C'mon.

These so-called "DEMOCRAT AGENCIES"...

-Ensure our food is safe to eat
-Keep our air and water clean
-Alert us to natural disasters
-Protect us from financial fraud and scammers

Remember what Trump is actually attacking.

The great @kschake.bsky.social does not mince words about what Trump and Hegseth did yesterday in that packed auditorium.

Kori Schake: “Yesterday morning, Trump and Hegseth behaved reprehensibly. Their speeches…were tantamount to incitement—a genuinely dangerous effort to suborn the military’s oath and condition them for using violence against their fellow Americans.” foreignpolicy.com/2025/10/01/t...
