An NIH stop-work order threatened the lives of monkeys involved in a Harvard-led study. Then came a $500,000 donation. - The Boston Globe The rhesus macaques were at risk of being prematurely euthanized after the $60 million research project, led in part by a Harvard scientist, was cut off from its NIH funding this week.

Last year, our science team stepped in with emergency funding to save TB vaccine research that was about to be shut down due to NIH cuts. Cool to see this new paper from some of those researchers randomly cross my desk (and cite my colleague Abie Rohrig)!

Blocking new housing doesn't stop rich people from moving in. Instead, it means unleashing them on the existing housing stock.

In SF, increased demand from the tech boom was not met with new supply, so landlords withdrew their rentals to sell to tech workers.

"Models keep getting more impressive at the rate the short timelines people predict, but more useful at the rate the long timelines people predict."

In a year of steep challenges, there were still shining moments in global health The Trump administration's deep cuts in U.S. foreign health aid had a devastating impact. Yet there were achievements of note in spite of it all.

Despite unprecedented cuts to global aid, there were still bright spots for global health in 2025, including progress on reducing lead exposure.

Anti-Portfolio Honoring the companies we missed.

I think we likely should have funded OWID earlier, but b/c they focus on many different areas, they didn't easily slot into one of our funds. (I ended up funding them through a discretionary grant.)

I’m excited to bring them from our β€œanti-portfolio” to our portfolio.

... and lastly, we've updated how we compare their cost-effectiveness measures to ours; we now think this additional funding roughly equalizes GiveWell’s funding bar with ours.

The main reasons for increasing our support:

Our Planned Allocation to GiveWell’s Recommendations for the Next Few Years | Coefficient Giving This post outlines our plans for funding GiveWell's recommended charities from 2023-25, how we decided on those plans, and why we still view GiveWell as the gold standard for donors seeking evidence-backed giving opportunities.

In 2023, we committed $300m over three years to GiveWell’s evidence-backed, cost-effective global health recommendations.

We’ve now decided to renew that support early and increase it.
