How does life evolve to adapt to modern cities?

Out now in Science, my PhD work with @lindymcbr.bsky.social uncovers the ancient origin of the “London Underground mosquito” – one of the most iconic examples of urban adaptation.

Ground breaking work here from my esteemed colleague @kelseytea.bsky.social !

Natural behavior + neural mechanism + genetics tell a beautiful story about the evolution of an adaptive behavior in wild mice

Read it!

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity!

We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵

When part of a word is replaced by noise, humans still hear the whole word. How do brains do this?

The zebra finch auditory cortex reconstructs occluded syllables in conspecific song - Nature Communications
Neural mechanisms underlying auditory restoration are not fully understood. Here authors show that, neural populations of the zebra finch in the equivalent of auditory cortex respond to song with deleted syllables as if the missing syllables were actually present, indicating that information about the temporal structure of song is stored in this area. Their findings suggest that the internal model has a generalized representation of species-typical syntax.

In mice, rats, and monkeys, a lack of serotonin in the brain leads to impaired maternal affiliation. @tianhuawang.bsky.social now showed that early social enrichment has ameliorating effects but leaves prominent reduction in pup ultrasonic calling untouched.
