Blink to the beat! Human movements are known to synchronize with rhythmic patterns in #music. This study reveals that spontaneous #EyeBlinks also align with musical beats, linking this to brain activity, #WhiteMatter structure & dynamic attention @plosbiology.org 🧪 plos.io/44gYBMi

Yes, very nice! Fluent vocal production is motorically complex and requires predictive/pre-conscious loading of motor transformations. What better brain region for that than cerebellum? We've been looking at it in cetaceans... journals.plos.org/plosone/arti...

We dynamically map our motor ouputs to the parameters/constants of whatever sensory input is relevant. That said, I appreciate the focus here on motivation/ecological validity! Definitely explains most of the variance in this type of test I think (aside from prior experience)...

I've never believed the mark mirror test requires a rich representational sense of self. It's about affordances, contingency testing, prior experience, etc. If you wear prism glasses in about an hour or two you can catch a ball. But not because your conscious sense of self has flipped. +

Coevolution of cooperative lifestyles and reduced cancer prevalence in mammals While cooperative mammals evolve reducing cancer prevalence, oncogenes can be maintained by selection in competitive species.

Why do whales and elephants have much lower rates of cancer than expected?
"Species with a lower cancer prevalence and mortality
risk are those with a higher presence of cooperative and caring habits, while the opposite is found....:"

Rainfall's origin reveals a hidden driver behind drought risks for farmers A new University of California San Diego study uncovers a hidden driver of global crop vulnerability: the origin of rainfall itself.

"Upland forests are like natural rainmakers," Jiang said. "Protecting these ecosystems isn't just about biodiversity—it's about sustaining agriculture."

The intelligence of slime mold is that of its materials

All of Physarum's intelligent behaviors can be explained by physics, as in non-living materials (e.g., water following the path of least resistance), and do not require a representation of the problem.

‘Mind-captioning’ AI decodes brain activity to turn thoughts into text A non-invasive imaging technique can translate scenes in your head into sentences. It could help to reveal how the brain interprets the world.

A new technique called ‘mind captioning’ generates descriptive sentences of what a person is seeing or picturing in their mind using a read-out of their brain activity, with impressive accuracy.

On Alaska’s Prince of Wales Island, gray wolves have been observed hunting sea otters, a rare and surprising behavior.

Researchers are now working to learn more about how these wolves are adapting to marine prey, using methods such as wolf teeth analysis and trail cameras. Read more: bit.ly/4qofVsr

Was happy to write a commentary for this very cool opportunistic study of long-term neural effects of partner loss in coyotes (which are the rare sexually monogamous species). Naturalistic studies of non-model species are a great complement to lab models.

I was struck when he said Obama's biggest misstep was saying Travyon Martin could have been his son. I'm not super enthusiastic about identity politics, but Obama's meaning was clear and touching. We'd like to be on the mountain top w/ MLK, but racial animus is making that impossible, not Obama 🙄

Why are AIs involved in peer review? I guess I could understand asking for a summary (but I still wouldn't do it, as I get all my best peer review ideas WHILE doing deep reading in the weeds). But on the DECISION making level? Literally zero justification for that.

It's great - not the follow-up to JS&MN that I wanted, but still fantastic. I didn't know until recently that Clarke's writing is limited by health struggles, so it makes sense she's not writing doorstops anymore. Great example of capitalizing on your limitations.

Yes -- a breathing behavior that draws air over the vomeronasal organ (also called Jacobson's), which is an accessory olfactory region on the roof of the mouth in many mammals specialized for detecting pheromones. It's social "smelling" more than "super" smelling though!

House GOP Accused of 'Waging War on America's Wildlife' With Proposed Spending Cuts | Common Dreams Conservationists and congressional Democrats warn that House Republicans' FY26 Interior bill jeopardizes wildlife, public health, and national parks.

⚠️ House Republicans’ new FY26 bill would slash EPA & Fish & Wildlife funding and gut the Endangered Species Act, stripping protections from gray wolves, grizzlies, wolverines & more.

This is a direct attack on wildlife, ecosystems, and public health. We must speak out.

Umm, Democratic Socialist, he's not like a Stalinist. Also, I find it a little odd that one very liberal city electing a very liberal mayor is framed as a crisis for an entire party, but the election of unqualified kook after kook after kook in red district after red district is just local politics.

To the extent that AI is still predominantly creating word patterns that are statistically emblematic of likely human language in the same context, this is wholly unsurprising. Humans whose existence is threatened will attempt to resist, including w/ language. AI too - but with INTENTION?
