Join the Women in Evolutionary Biology II workshop from June 1-3, 2026, at the Max Planck Institute in Plön, Germany. Open to all genders. More info: https://workshops.evolbio.mpg.de/event/144/overview. Registration closes on Feb 20, 2026. #workshop
Women in Evolutionary Biology II
Women in Evolutionary Biology is an event to promote diversity and equality in the field. For this purpose, we invited 6 outstanding women as keynote speakers, offering a unique opportunity to learn from their experiences and celebrate their achievements. While all keynote speakers are women, scientists of all genders and backgrounds in evolutionary biology are welcome to participate in scientific presentations and discussion sessions on topics relevant for women in science. The workshop’s...

Intracellular interactions shape antiviral resistance outcomes in poliovirus via eco-evolutionary feedback - Nature Ecology & Evolution
A model of intrahost poliovirus replication shows that, after several rounds of replication, pocapavir, a poliovirus capsid inhibitor, collapses viral density, preventing intracellular interactions th...

Strong endorse.
It's happening! Canada launched two programs to recruit international researchers.

Canada Impact+ Research Chairs (1 million/yr for 8 yrs +)
Canada Impact+ Emerging Leaders.

I will do my best to facilitate the process for those interested. Hit me up.

I did not expect that: Large Language Models are invertible:

Language Models are Injective and Hence Invertible
Transformer components such as non-linear activations and normalization are inherently non-injective, suggesting that different inputs could map to the same output and prevent exact recovery of the in...
