The special sounds and gestures made by infant bonobos also known as pygmy chimpanzees when they are tickled suggest that the origins of laughter may pre-date human evolution, according to a new report

Zimmerman believes that her findings confirm a hypothesis that laughter originated in primates, as a universal signal of wellbeing in a playful situation to help regulate social interactions, the report says.

A number of recent hypotheses have attempted to explain the ultimate evolutionary origins of laughter and humor. However, most of these have lacked breadth in their evolutionary frameworks while neglecting the empirical existence of two distinct types of laughter—Duchenne and non‐Duchenne—and the implications of this distinction for the evolution of laughter as a signal. Most of these hypotheses have also been proposed in relative isolation of each other and remain disjointed from the relevant empirical literature. Here we attempt to remedy these shortcomings through a synthesis of previous laughter and humor research followed by (i) a reevaluation of this research in light of theory and data from several relevant disciplines, and (ii) the proposal of a synthetic evolutionary

I'm just starting out with Clojure and I was trying to implement vim's keywordprg, which displays documentation for the word under the cursor. I want to call the doc() function on the value of a variable, but I'm not having any luck:

user=> (let [x "println"] (doc x))
-------------------------
user/x
nil

In Perl, I think I could use the eval() function, but I'm not seeing anything comparable in Clojure. Any suggestions? Thanks!

It all started back in 2019 before I was working at Skyscanner. I remember sitting in a cafe in Budapest reading the latest conversations online about the new brand update.

Perhaps more than any other person in history, Leonardo da Vinci showed the kind of magic that can happen in the overlap between art and science, where much of web development lives. His methods and outlooks are just as applicable to the web today as they were in Renaissance Italy.

If you made it big in seventeenth-century Bavaria, you showed it by creating a garden with all the plants in the known world. That's what Johann Konrad von Gemmingen, Prince-Bishop of Eichstätt did, anyway, and he wasn't about to let his botanical wonderland die with him.

A vintage Stanley Bedrock model, even unrestored, will cost you more than a new TayTools version. Vintage planes are only good if you know how to properly restore and tune one. A new woodworker who has never used a good plane has no idea how one is supposed to feel. I have seen many folks "restore" planes, only to put them on a shelf because they still don't work properly. I used to blame them for that. Rob Cosman was the one who helped me see things differently. He said when he put a premium plane in a student's hands, the difference was night and day. After they had experience with a good plane, they were more equipped to go the "vintage" router for their next one.
