I was looking for a game to practice my portugese a while back and got recommended this series, but never actually tried any. This looks cool! A vida encontra um caminho..

Learned use of an innate sound-meaning association in birds - Nature Ecology & Evolution Over 20 species of geographically and phylogenetically diverse bird species produce convergent whining vocalizations towards their respective brood parasites. Model presentation and playback experiments across multiple continents suggest that these learned calls provoke an innate response even among allopatric species.

This is an awe-inspiring and fascinating study that I thoroughly enjoyed reading. However, the overall framing in terms of "innate versus learned” is unnecessary. The innate versus acquired dichotomy is outdated and has been for a long time. www.nature.com/articles/s41...

It's wild coming from cognitive science to comparative cognition. In cogsci, cognitivism is largely seen as dead and has been for some 20+ years.

It is common to view cognition as being for action. In psychology too.

Yet, this is where they put the blame? The field needs more cogsci, not less.

Octopuses respond to the rubber hand illusion. Check out the video abstract. Cool work by Sumire Kawashima and Yuzuru Ikeda--these are the kinds of questions we can be asking to investigate the nature of consciousness www.cell.com/current-biol...

Which Kind of Science Reform What hope is there for science reform, if we can't agree on what to reform? Right now, principles are more important than practices.

How can we reform science? I have some ideas. But I am not sure you’ll like them, because they don’t promise much. elevanth.org/blog/2025/07...

Now, some thoughts on seeing Aquilops on the big screen! "Our" little dino was one of the stars of Jurassic World, and that was quite an experience as one of the scientists behind the research. (1/n)

Why did cephalopods develop intelligence? And why, being so intelligent and cognitively complex, do they die so young? In this @cp-trendsecolevo.bsky.social ‪paper, the authors explore this paradox from an ecological and evolutionary perspective. www.cell.com/action/showP...

Our letter is out in @cp-trendscognsci.bsky.social

We argue against a recent claim that animals cannot make mental simulations because they supposedly do not reliably memorize sequences. The evidence for model-based animal cognition is too overwhelming. 🧪

Temporal integration and decision-making in crocodiles Summary: Crocodiles' attraction to two sensory stimuli (water vibration and airborne sound) is independent of the order of arrival of these stimuli, within the limit of a certain time window.

A 2.5 meters long female alligator which kept her juvenile colouration. She has a dark back and a yellow underside, notably with yellow lower jaw and throat and yellow stripes on her flank. She lies serenely on the green, fake grass of an indoor enclosure, with a wall and doors in the background.

A close-up on the head of the alligator in the previous picture. She has a juvenile colouration with a dark back and a light yellow lower jaw and throat. We can see the big teeth coming out of her upper jaw and the black pupil in her dark brown eye. She lies serenely on green, fake grass of an indoor enclosure.

I did some data collection with the alligators yesterday and I took a couple of pictures of Sigi after her feeding. She was probably feeling very satisfied.

The field of behaviour genetics has turned out to be something of a damp squib: “genomic information is a statistically non-zero but all in all relatively minor contributor to behavioral differences”

Forelimb reduction and digit loss were evolutionarily decoupled in oviraptorosaurian theropod dinosaurs | Royal Society Open Science Theropod forelimbs exhibit wide morphological disparity, from the elongated wings of birds to the diminutive arms of T. rex. A wealth of work has sought to understand the evolution of bird flight via ...

Many theropods shortened their arms and lost fingers. How did they do it?
Our Edinburgh student Milly Mead, in her first paper, looks into oviraptorosaurs. Arm shortening and finger loss were decoupled!
