Eight-armed buffet: Divers record video of an octopus eating one of its own

Flock to this: A new analysis of anatomical features shows birds evolved gradually from dinosaurs

On Tuesday I wrote about my experience diving in a deep-sea submarine, but going on right now are two live-streaming deep-sea expeditions that allow you incredible access to the deep sea from the comfort of your own home.

Bob Dylan asked: "Are birds free from the chains of the skyway?" Sure, this is a metaphor (in Dylan's case, for a lost love) but it works because the complexities of avian flight—from migration and navigation to group dynamics—have long been a mystery, one with a preponderance of ideas, but few firm answers.

I'm still not sure whether I blog about Mesozoic archosaurs - specifically dinosaurs and pterosaurs - too often, or too infrequently. As I always say, the problem as I see it is that dinosaurs and pterosaurs have so much presence in the blogosphere that writing about them always feels like jumping on a bandwagon.

CAMBRIDGE, Mass.—What happens in the brains of people who see Jesus in a piece of toast? What are the physics of slipping on a banana peel?

After the Chicxulub meteorite, more than half the plant species in temperate North America perished along with the dinosaurs, and the composition of post-impact vegetation changed markedly. Christopher Intagliata reports

I'm an unashamed fan of cryptozoology - this being (for the two of you that don't know) the field of study that revolves around those creatures thought to exist by some, but which remain unrecognised by mainstream science in general.

When an endangered species stops breeding, you know its days are probably numbered. In China the countdown has apparently begun for the critically endangered Chinese sturgeon (Acipenser sinensis).

On this blog, in my book The End of War and elsewhere (see Further Reading and Viewing), I have knocked the deep roots theory of war, which holds that war stems from an instinct deeply embedded in the genes of our male ancestors.

Longer-lived creatures, from fish to shellfish, would not be able to evolve their way out of trouble
