Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success.

The data is in: the NIH goalposts have shifted.

What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards.

Another manifestation of how HHS policies have led to fewer awards and less science.

UNC-Chapel Hill Concludes Civics School Investigation, Won’t Release Findings A law firm's external investigation into UNC-CH's civics school is complete, but the university won't provide details.

unc has concluded it's investigation into the school of civic life and leadership and it's standing behind jed atkins as dean.

beyond that, we didn't learn anything specific about what they found or what they're doing about it

USAID’s Emergency Food Security Program spent $4 billion in FY2022 to feed 114 million people in 55 countries. We just blew that much money in four days of this war.

"Fuqua classrooms are equipped with cameras and microphones. Under the new system, students would check in by scanning NFC tags at their seats. This would be used to ascertain the exact position of speakers. Transcripts are then fed to an in-house AI system that "objectively" grades participation."

If anyone is friends with any Georgian air traffic controllers, buy them a nice bottle of wine. As guardians of pretty much the only narrow gap still available between Europe and Asia that avoids both Iran, the Gulf, Ukraine and Russia, they are under some substantial pressure.

The decline of child stunting in 122 countries: a systematic review of child growth studies since the 19th century Introduction Child stunting, a measure of malnutrition, is a major global health challenge affecting 148.1 million children in 2022. Global stunting rates have declined from 47.2% in 1985 to 22.3% in ...

Eradicating child stunting was a central feature of the modern health transition. A new paper reviews 923 child growth studies in 122 countries 1814-2016 to show massive decline in child stunting in the 20th century even in hi income countries & surprising heterogeneity in the regional trajectories.

Do disaster-relief cash transfers trap people in risky areas, or help them adapt? Disaster relief can discourage people from adapting to future disasters – for example, by reducing incentives to relocate. But in low-income settings, cash relief can also ease liquidity constraints and enable adaptation. Evidence from Pakistan’s 2010 floods shows that both of these forces exist but that they offset each other, so that cash relief does not cause more people to stay in disaster-prone areas.

πŸ†• Do disaster-relief cash transfers trap people in risky areas, or help them adapt?

Today on VoxDev, Muhammad Bin Khalid (Harvard) & Martin Mattsson (NUS) discuss how disaster relief enabled climate adaptation in Pakistan: https://ow.ly/XAgU50YiFE7

See those two dots with arrows pointing to them?

They're giant gas planets orbiting their star, located 307 lightyears away.

These are directly imaged exoplanets.
