Exercise-induced activation of ventromedial hypothalamic steroidogenic factor-1 neurons mediates improvements in endurance
Kindel et al. show that repeated exercise potentiates the activity of ventromedial
hypothalamic SF1-expressing neurons. SF1 neural activity is required for mice to achieve
the endurance benefits of ex...

We use signal correlations and noise correlations in chronic imaging data to show that representational drift is shaped by a balance between Hebbian and stochastic changes.

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?

Same, I read that NYT heading and thought, "What? you can't repeal a finding."
You can't... repeal... a scientific finding. At that point it's just called lying about it.

Another thing that in normal times would be on the front page of all those things we used to read called newspapers
A Reuters photographer captured this image of a page from Pam Bondi's "burn book," which she used to counter any questions from Democratic lawmakers during an unhinged hearing today.
It looks like the DOJ monitored members of Congress’s searches of the unredacted Epstein files.
Just wow.
