We really ♥️ this piece from John Hawks on humans looking at the stars, especially how he picks up African cosmologies on the link of the to 🩸

Right now I'm involved in one of the MOST important papers of my life with Hadza hunter-gatherer experts on Hadza beliefs and practice around menstruation, hunting and the moon.

The key here is no one understands Hadza --their moon-scheduled ritual for healing and good hunting--unless they also understand menstrual beliefs and practice.

[Dark matter really does exist!] Data acquired by the space mission reveals that the speed of stars in our galaxy, the Milky Way, decreases at great distances from the galactic center.

Two IRAP researchers have shown that only a model that includes dark matter can accurately reproduce the observed decrease. Gone is the MOND (MOdified Newtonian Dynamics) theory ...

This is very well said. I'm spreading the word. I want to know Freedom before I die. I'm not participating in collective suicide. You should commit suicide individually if you don't heed this.

Spent the week trying to attend (or watch remotely) all or most of our internal talks by students:
a total of 37 (!!) for the PhD course in and in our Department...and only considering the students of year 1 and 2 (i.e. not the final year ones).

Time demanding, but also a nice way to explore what's boiling in all open research fields in and know what are the challenges and the mysteries around!
