Big Science vs. Little Science: How Scientific Impact Scales with Funding Agencies that fund scientific research must choose: is it more effective to give large grants to a few elite researchers, or small grants to many researchers? Large grants would be more effective only...

Research also shows that spreading smaller amounts of funding out over more researchers generally delivers better scientific outcomes per dollar spent than focusing bigger grants on fewer researchers.

He did it! Almost 400K ft elevation gain in 31 days. Imagine that!!

A meme using the "Distracted Boyfriend" template showing a man in a blue plaid shirt (labeled "GRADUATE STUDENTS") looking back at a woman in a red dress (labeled "HANDS-ON GHIST COMPETITION EXPERIENCE") while walking with his girlfriend in light blue (labeled "THEORETICAL POP GEN COURSES"). The image satirizes graduate students being tempted by practical competition experience over theoretical population genetics coursework.

We all know hand-on learning is best. If you're a student interested in population genetics inference, compete in GHIST! ghi.st . You can even get started without installing any software using our webapps: ryangutenkunst-dadi-two-epoch.hf.space and ryangutenkunst-sweep-detection-dpi.hf.space .

The rise of historical epigenomics and temporal analysis of gene regulation - Genome Biology Complex diseases driven by gene-environment interactions impose a heavy burden on human and animal health. Addressing these challenges requires innovative research. The emerging field of historical epigenomics offers a promising opportunity to link genotypes with phenotypes using preserved biological material. New methods such as historical chromatin profiling in museum specimens provide valuable insights into vertebrate genome regulation. Building on successful work with formalin-fixed paraffin-embedded (FFPE) samples, we expect growing interest in using historical specimens for biomedical, evolutionary, and ecological research. Applied to historical collections, these tools can provide critical baselines for understanding modern diseases, environmental stressors, and human adaptation.

Israel has just arrested Greta Thunberg and many others.

Statement from the Global Sumud Flotilla:

“People of conscience have been abducted. The flotilla broke no laws. What is illegal is Israel’s genocide, Israel’s illegal blockade of Gaza, and Israel’s use of starvation as a weapon.”

Me giving a talk, barely visible behind a giant podium. About five minutes later, the fire alarm went off, and we all had to go outside for a while. But hey, at least the audience were awake after that! Photo by Dorothea Mylopotamitaki.

And that's a wrap on Bone Diagenesis 2025! What a lovely conference, full of kind and brilliant scientists. Also the first time my talk has been so 🔥🔥🔥 it set off the fire alarm (I'm choosing to assume that was the reason) 😅

I wrote my new Nature World View in this transition — one last reflection before leaving Colombia. It explains why inequities persist in science, even when dressed up as inclusion, and why we must stop mistaking access for change. 👉 rdcu.be/eGEun

Ecology and evolution of virulence Silva and King discuss the concept of virulence and the ecological and evolutionary factors that shape it.
