Time again for another week’s roundup of Twitter #weirdscifacts! This week we reached the dubious milestone of fact #666! To celebrate, we provide a bonus fact, and two of the facts this week are my own posts on WEIIIIIIRD OPTIIIIIIICS!!!
663. Jan 05: A camera fast enough to watch light move? The link leads to my own post on the “picosecond camera”, which can record images — with some caveats — as such a rate as to track the motion of a pulse of light!
664. Jan 06: What happens when your brain is split in two — and you survive? With the connection between the left/right halves severed, many bizarre “split personality” behaviors have been observed. (h/t @jenlucpiquant)
665. Jan 07: So, what is a “temporal cloak“, anyway? Another of my posts, on the recent announcement of a cloak that can hide an event in time! Again, not quite as shocking as it initially sounds, but quite remarkable research.
666. Jan 08: Sharks contain urea (normally a component of urine) in their body tissue. Many species of fish are constantly losing water to the salt-rich seawater surrounding them, and much replenish it. Sharks, however, use urea to help keep the ion balance in their body comparable to that of the sea. (h/t @whysharksmatter)
