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.

The editorial cartoonist's pen is one of the sharpest tools in journalism, whittling issues down to basics for satire or rage. I'm proud to say that my long-ago colleague, Milt Priggee, is unafraid to shock with a tough point of view.

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 🧪 www.newscientist.com/article/2511...

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

Minneapolis, Minnesota
For Renee Nicole Good
Killed by ICE. on January 7, 2026
by Amanda Gorman
They say she is no more, That there her absence roars, Blood-blown like a rose.
Iced wheels flinched & froze.
Now, bare riot of candles, Dark fury of flowers, Pure howling of hymns.
If for us she arose,
Somewhere, in the pitched deep of our grief, Crouches our power,
The howl where we begin,
Straining upon the edge of the crooked crater Of the worst of what we've been.
Change is only possible, & all the greater, When the labour
& bitter anger of our neighbors
Is moved by the love
* better angels of our nature.
