A plant fossil from 1.6 bya pushes back the date when complex life first evolved. So now it’s about a billion years between complex life and the Cambrian explosion – which only raises more questions. Here’s the popular press, and here’s the original article.
Slightly dubious, but maybe North American mass extinctions 12 kya, along with the disappearance of Clovis people, are due to an extraterrestrial impact?
Interesting profile of a controversial scientist, who is accused of unethical scientific conduct. I think it’s a good example of how hard it is to establish that a scientist has falsified data. This could be useful for my Biology & Politics class, but it might be unnecessary or tangential.
It kinda looks like Donald Trump and his organization profited from a corrupt real estate deal in Azerbaijan that helped funnel money to Islamic extremists.
Terrestrial-style eyes evolved before legs! The hypothesis now is that having the good eyesight would let fish sit in the shallows and eat terrestrial invertebrates.
It’s important to be vigilant about infringements upon civil liberties. But I find that I have to continually remind people that not all speech is protected speech.

Exoplanets! Don’t get carried away, though, we have no idea what they look like.
