My lab studies oxytocin and cooperation, hormonal and neurochemical effects on communication, social bonding, behavioral synchrony and division of labor, and we dabble in neuroplasticity and the immune system. Science is fun! Animal behavior is my passion.

Why is same-sex sexual behaviour turning out to be so common among animals? It's often assumed to be a disadvantage in evolutionary terms, but it's looking more and more as if that assumption is entirely wrong 🧪

Is there an evolutionary reason for same-sex sexual behaviour?
Sexual behaviour among same-sex pairs is common in apes and monkeys, and a wide-ranging analysis suggests it does boost survival

The natural world is a wonderful place. This is timelapse video from a few years ago of a marine sponge sneezing. It has mucus inside that traps the sort of particles that might clog it up, and expels them in periodic contractions every 3-8 hours. Atchoo!

🍂 🏛️ 👿 🧪 US Congress Bill to Prohibit Funding for Research with China

Proposal bars funding for US scientists working with Chinese partners or training Chinese students; bill is retroactive - interactions in previous 5 yrs could cause ineligibility for future Federal funding
This has gotten surprisingly little attention — it's not even on the front page of @science.org right now — but it's really hard to describe what the SAFE Research Act would do to US science and scientists without sounding insane

*Please be patient.
During a shutdown NSF employees cannot open computers or respond to emails.

*Merit review will continue. However panels won’t resume until after Dec 8th.

*POs remain excited and committed to advancing science and the scientific workforce.

BREAKING: NSF will be relocating to the "Randolph Building," about half a mile from its current location in Alexandria, where they will co-locate with the US Patent and Trademark Office. The lease will begin January 1, 2026.

As NSF GRFP is in the news, PLEASE spread the word about the new EGFP program they have for past GRFP honorable mentions. Universities in eligible states can apply to get funding for HMs in the same amount as GRFP. My impression is that many depts don't know this exists and so don't apply.
