The spread of tool technology is interesting in its own right. Beginning at 3 million years ago nothing much happened for 2 700 000 years then we get some real innovation happening. The photo in the article has some multi-views of the same tool and it gives it a mass produced look yet the repeats are just multiple images of the same tool. The key thing here is that our modern Homo sapiens are late comers to the innovation party.
The article on termite mounds is actually quite amazing, to think an insect covering a size of land the area of the UK and not being able to find one central queen chamber. I would like it if they published a kmz of the area.
The article on the ultra diffuse galaxy seems to be riddled with contradictions and is rather hard to follow. At 9500 light year span it is less than 10 percent the width of the Milky Way. The real story here, and the star of the show is European space telescope GIA which is just nailing all the distances using parallax. My concern is that the variable light distance estimates using variables require relative magnitudes that would be near impossible to pin down through the central fog of our galaxy.
