The deforestation of the Amazon surged under Bolsonaro. Now under Lula it has fallen to the lowest on record. Bolsonaro's son, now running for president, threatens to reverse that. trib.al/75BfbU8

Brazil’s election is likely the most unfollowed global event. Do you like breathing oxygen? Then you should care who wins next week, bc one guy wants you to keep breathing and the other wants to burn trees

A Fields Medal is basically the Nobel Prize of math. One of the guys who won it cried so hard Tuesday night that he woke up his daughter. The reason? OpenAI dumped 719 AI-written proofs onto the internet in one night, claiming to solve math problems that have stumped humans for decades. 16 of them were problems Hugo Duminil-Copin spent his career working on. He told Le Monde they annihilated his field of research. Here's the part the headlines are missing though. Nobody actually knows if the proofs are right. Not one of the 719 has been peer reviewed. Three already got pulled within a week because of a single sign error, and 14 more got quietly revised. The model spent about 3 hours of compute per result, but a human checking the 3,500 pages covering just Hugo's 16 problems would need years. So every working mathematician wakes up to the same lousy choice. Spend the next decade grading a machine's homework, or ignore the dump and risk burning years on a problem that's secretly already solved. And the reaction might do more damage than the papers. Some mathematicians are already saying they'll share fewer of the problems they work on. Duminil-Copin says the whole culture of circulating ideas is shattering. That culture is the engine of the field. Hilbert posted 23 open problems in 1900 and they steered a century of research. Posting an open problem is how a young mathematician finds their life's work. If posting one now means handing a lab a target, people stop posting. Which means OpenAI could be wrong about every single proof and still break mathematics. A field where people stop sharing problems stops being a field.

Il s’inquiète particulièrement de l’avenir des jeunes chercheurs et évoque un « démantèlement » de sa discipline. (Le Monde)

Last week, California Governor Gavin Newsom signed legislation requiring large businesses to try to connect you with a human within 15 minutes of asking, or schedule a callback—taking effect in 2027. It's part of a wave of state measures targeting the administrative and financial burden of the "annoyance economy.”

Basically, what Canadians have heard from President Trump (and his Cabinet) since January 2025 is the following: “you are the equivalent of a piece of s**t. We don’t need you; you are nothing without us. We will use economic pressure to force you into submission. It doesn’t matter that we have a free trade agreement between us, setting out the rules. It doesn’t matter that that agreement was my idea. It doesn’t matter that I praised the agreement as being “the best one ever.” No matter what those rules say, I’ll do whatever I want to you whenever I feel the urge to do so. It kind of gives me pleasure to hurt you economically; I especially enjoy humiliating you. You should sit back and welcome that. You absolutely shouldn’t complain about it. If you dare hit back, I’ll strike you even harder. We can retaliate; you cannot! And don’t even think about looking for any new relationships. If you try that, I’ll scorch the earth under you – and I’ll make any country entering into agreements with you regret doing so.” This meets the classic definition of an abusive relationship. It still shocks us that the U.S. now behaves this way. Canadian businesses and individuals treasure the connections we have to Americans. These bonds have been formed over centuries and have greatly benefitted both Americans and Canadians. We wish more Americans were acting to stop their Administration from destroying what we’ve built together. Sadly, the only predictability – for the time being – is more of the same from the Trump Administration. All threats, all the time. Our government understands that Canadians, overwhelmingly, see no plus sides in succumbing to this grotesque harassment. We can’t have confidence that this menacing behavior will stop anytime soon; we know, based on common understandings of how bullies behave, that ignoring or tolerating such abuse simply invites more of it. In recent times, albeit in different ways, Russia & China have been the most consistent big power “aggressors” in international relations. Under President Trump, the U.S. has chosen to join that group. Canadians are coming to understand the costs we’re likely to bear from preserving our self-respect and our sovereign rights as a country to pursue our collective interest. It’s all very unfortunate (to put it mildly). Weaning ourselves from disproportionate dependence on buying from and selling to Americans will be hard. But our leaders have been left with few options. Mercifully, there are still many jurisdictions in this world that behave ‘normally’. That aren’t predators. That are interested in partnership, not dominance. We need to deepen our relations with as many of those as we possibly can. Who knows what “Associate Membership” in the EU will mean, if it ever comes to pass. Canada isn’t interested in being governed by Brussels any more than we’re interested in being governed by Washington. So, this may lead only to deepened trade relationships, maybe only in certain sectors. If so, that’s still better than being so heavily exposed to the whims of an ever-more-hostile U.S. Administration.

Fmr U.S. Ambassador Susan Rice: "If you're sitting in Canada, whether you're a farmer or a citizen or in the PM's office, the only rational conclusion is that Canada has to reduce its reliance on the US. It's got to diversify its economic partnerships, its security relationships. It's got to look out for its own interests, and it can no longer count on a mutually beneficial, enduring relationship with the US."

Maria Popova is famous for her personal blog, The Marginalian, where she's published more than six million words. All the nights I've spent reading her writing were like an entry point into intellectual curiosity. She's introduced me to more writers and ideas than just about anybody, and this conversation is about how she does it.

'Blue Heron' is the most acclaimed film of 2026, and director Sophy Romvari says its existence can be credited to grants provided by the Canadian government at both the script and production stages. “I really did make exactly the movie I wanted to make.... When I started making work in Canada, I was not aware of the privilege of living in a country that has access to arts funding. The version of this film that I would’ve made within the American system would be very, very different — and I don’t know if that one would’ve gotten distribution.” bit.ly/4ekNFn5

Massive geopolitical shift in conservation. Canadian Prime Minister Mark Carney just announced a staggering 3.8 billion dollar strategy to protect 30 percent of the nation's lands and waters by 2030. A monumental step against corporate destruction of the environment.

I’m devastated. A good friend and dormmate of mine, Amin Pourfarhang, has been sentenced to death after protesting in Iran 😭 He’s one of the kindest people I’ve ever known. Please share. Visibility raises the cost for the Islamic Republic and may stop this execution!

Of course speech is sometimes violence. Ask the Tutsis who were murdered by their neighbours after being called cockroaches and vermin on radio for weeks. Dehumanizing people via speech is part of murder.
Speech is not violence. Violence is not speech.

We’re expanding the Canadian Dental Care Plan. Starting today, Canadians aged 55-64 can apply. In the coming weeks, applications will open to Canadians aged 18-54.   Because of this plan, millions of people can now afford to see a dentist — some for the first time in decades. Soon, millions more will get that same care.
