I just learned that Threads has approximately 141.5 million to 150 million daily active users, X has around 125 million daily mobile users (with total daily active users estimated higher), and Bluesky has roughly 1.5 million to 3.5 million daily active users What happened to Bluesky?

This is a disaster Funding from the National Science Foundation's directorate of Social, Behavioral and Economic Sciences (SBE) has dropped by 90%. This is doing massive damage to crucially important scientific fields and is going to ruin many young scientific careers in these fields.

But no part was hit as hard as SBE, which went from an average of 800 new grants to just 91, a precipitous, 90% decline. SBE spent just 95 million on new grants, far less than its average of 247 million.

The government *still* isn’t tracking how often immigration agents detain U.S. citizens. We are. 500+ Americans have been handcuffed, held at gunpoint or held against their will in Trump’s second term. Our tally is almost certainly an undercount. THREAD (content warning: violence) ⬇️

The most common outcome of a report to Title IX is that nothing happens. That’s by design. According to school policies (and now, Trump’s 2020 federal regulation), a report is just a way for schools to receive information about violence. It does not require any action from the school.

"Americans are more likely to have placed a bet than to have read a book in the past year" Online sports betting increases the likelihood of bankruptcy and cientists view gambling addiction as a public health issue, linked to anxiety, depression & suicidal ideation www.npr.org/2026/10/02/n...

After bankruptcy, he was banned from sports betting sites. Then he discovered Kalshi

The dark side of the prediction market boom is becoming more clear: Experts say the sites have become go-to outlets for gambling addicts to relapse as the companies avoid state consumer protections.

Devistating. And against Congress's directive. SBE was included in the 26 budget and the NSF section states that "no directorate shall receive more than a 5 percent reduction relative to the fiscal year 2024 enacted level."

The fiscal year is over. The dying Social, Behavioral, and Economic division of NSF ended up awarding 90 total grants this year, as opposed to ~700-800 in recent past years. Source: grantwitness.org/nsf/analyses...

The graph shows the cumulative number of awards made by month across this fiscal year, as compared to the last 6 fiscal years. The line for this year is total flat until June, but then finally gets up to 91 by October. In prior years the increase starts building earlier and ends on average in the 700-800 range (with variability, last year was only between 400-500).

Happiness is plummeting, especially among young people. When I see demoralizing data like this over and over again (e.g., test scores dropping, loneliness on the rise, etc), I just think we need to change course. Defending the status quo seems like such a bad option.

The Cornell case reveals a serious problem with social norms & institutions: 1) When people refuse to intervene when harassment or an assault is happening, that is a failure of norms 2) When universities fail to take action, this is a problem with our institutions www.bbc.com/news/article...

Cornell case spotlights 'confusing' web of systems for reporting campus assaults

Victims often have to navigate both university and local law enforcement processes to find justice.

AI bots are flooding researchers with requests for money and time AI agents are spamming researchers with emails wanting to collaborate or offering services for money I'm getting these emails and they make it less likely that I will respond to real people www.nature.com/articles/d41...

AI bots are flooding researchers with requests for money and time

Many scientists use artificial intelligence in their work, but agents are increasingly soliciting researchers for collaborations.
