This morning in Biddeford, Maine, a 26-year-old man said goodbye to his wife and daughter and left for work. Moments later he was dead, shot in the head by ICE agents, the second man ICE has killed in six days. ICE is killing our neighbors. ICE cannot be reformed. Abolish ICE.

My coauthor Jay Falk's postdoctoral fellowship was terminated by the Trump administration for documenting the hummingbird example in this paper.

Operational biological sex definitions applied to hummingbirds (Bleiweiss 1992; Bleiweiss 1999; Bleiweiss 2001; Diamant et al. 2021; Falk et al. 2022; Falk et al. 2021) where sex is operationally defined by binary plumage phenotypes in the field. Each row depicts a wild individual hummingbird with morphological traits (beak length, plumage coloration), behavioural traits (territoriality) and their unobserved gamete type. This example illustrates how the same individual can be operationally defined as one sex in the field (based on external phenotypes) but classified as a different sex based on their gametes (which cannot be easily observed in the field), highlighting how definitional choices shape scientific reporting of sex.

In our Viewpoint (onlinelibrary.wiley.com/doi/abs/10.1...) we synthesize the gametic definition (outlined by Janicke et al below) and other definitions of sex (e.g., multivariate definition). We contend that is NO consensus on “biological sex” (maybe a consensus isn’t actually necessary…)

Hey team - it’s looking very likely that I’ll be hiring not one but two four year postdocs! We’re a fun lab with tons of theoretical and applied pop gen projects - broadly in polyploid, conservation, and human evo. Competitive salary, sunny San Diego! Do share with your about to defend grads!

There's an OMB rule change that would require political oversight of scientific grants, and could pull any that don't "reflect presidential priorities" Another country has tried this before! It was the USSR and it was called Lysenkoism. By @thsaey.bsky.social www.sciencenews.org/article/omb-...

Here’s what happens when you put politicians in charge of science

Proposed federal rules would rely on political appointees to decide how a lot of U.S. science gets done. History shows the consequences of such actions.
