And Brazil defeated extremism, guns, environmental destruction, militarization, democratic threat, and organized crime ruling politics. It’s not going to be easy for Lula, he will need to do a very different government, but what a beautiful mobilization of civil society

O pessoal das “instituições não correm perigo” já começou a passar pano para os democratas bolsonaristas?
Arthur Carvalho retweeted
Qualquer que seja o resultado, o bolsonarismo já obteve uma vitória na sua cruzada de desmoralizar o sistema eleitoral brasileiro e enfraquecer a nossa democracia. Parabéns aos envolvidos.

Oscar Schmidt sadly never played in the NBA after being drafted by the Nets, but he was one of the giants of the game on the Olympic stage and beloved by Kobe Bryant for his high-scoring exploits in Italy.
The Brazilian great’s passing is a huge, huge loss for the whole sport.
A NBA lamenta profundamente o falecimento de Oscar Schmidt, lenda eterna do basquete brasileiro e um dos maiores nomes da história do esporte que tanto amamos.
Oscar chegou a ser selecionado no Draft da NBA de 1984, mas optou por seguir defendendo a Seleção Brasileira, pela qual conquistou diversos títulos, entre eles o histórico Ouro no Pan-Americano de 1987.
Nesse momento de profunda tristeza, os pensamentos estão com a família, amigos e milhões de fãs do nosso eterno Mão Santa.

Brazil just raised the tariffs of GPUs, CPUs, and RAM from 0-2% to 10-20%. The country produces zero (0) of these, but has abundant clean electricity to host datacenters. Couldn't think of a more self-defeating policy at this time.

On homogeneous production functions:
"The two most important 'degrees' in economics are the zeroth and first degree."
Footnote: "However, it is sometimes thought that the Masters and the Ph.D. are even more important"

Will US tariffs affect the geography of innovation and technological hegemony? Shall the EU retaliate to protect its high-tech industries? In this new @voxeu column, we present a framework to address these questions, and to think about the US-EU technology gap.

Jannik Sinner is not even the best player of *this* generation. The Novak comparisons are officially over. If there’s a future GOAT, it’s Carlos and not some player who is just a Medvedev who hits hard.

🚨 New paper on #JAMAHealthForum 🚨
If you walk into a random dialysis facility in the US, there’s
🔹 An 80% chance it’s owned by DaVita or Fresenius
🔹 A 30% chance it has physician owners
Both horizontal and vertical integration in this market have intensified over the past decade. And with greater market power, unsurprisingly, come higher prices. (A thread, 1/8)
Our latest work on consolidation in the dialysis industry, led by @xuyang_xia and joint with @PaulEliason2 @rileyleague et al.
