New paper: Reflecting on the multiple biases and predispositions observed in young animals with no previous experience, we modelled a new idea on the strategic role of biases to guide adaptive choice and reduce errors: royalsocietypublishing.org/rspb/article... In collab with @debivort.bsky.social
Please check out our proposed hypothesis about how naive animals might integrate multiple noisy signals to produce adaptive responses pre-learning.

There's also programs like 'Stop Passing the Harasser' where candidates can waive confidentiality and allow prospective employers to request info from prior/current employers on harassment/misconduct investigations. U Wisc and UC-Davis both do this, not sure how widespread it is yet

Now, ICE wants to build a new 400-bed facility in New Hampshire?
Governor Ayotte should be doing everything in her power to block this. Enough is enough.

The acting ICE director said federal officials previously told Governor Ayotte about the economic impacts of controversial facility. Ayotte said the director’s comments were “simply not true.”

Massachusetts has spent months delaying & denying @boltsmag.org’s public records requests on how many people it has transferred ICE during Trump as part of its formal contract with ICE.
A supervisor of records ruled last week that the state’s denials are improper; we hope to get records soon.

We know a lot more about #Fungi now that the science of genetics has advanced so much. Often it was discovered that 2 or more different fungi, were infact one species. With the 1 fungi 1 name push, we needed ways to divide. So #Anamorph is generally described as the asexual reproductive stage

Scientists thought they understood global warming. Then the past three years happened.
The fastest warming period since 1880 occurred in the past 30 years, according to a Washington Post analysis of NASA data.
