M Samuel Avery of Kansas City, Mo., was charged with killing his neighbor by shooting him in the head on his front porch after an argument over lawn-mowing noise stemming from what Avery described as a decade of hostility between the two.

A new discovery about jumping spiders could challenge some pretty hefty human assumptions about the cognitive abilities of arthropods.

Researchers in Germany monitored jumping spiders as they snoozed, and saw characteristic traits of REM sleep never observed before in invertebrates.

It's a question that keeps some scientists awake at night: Do spiders sleep? Daniela Roessler and her colleagues trained cameras on baby jumping spiders at night to find out.

During observation, the spiders’ overnight movements looked a lot like REM in other species — like dogs or cats twitching in their sleep. And they happened...

Nighttime video footage of baby jumping spiders showed patterns that looked a lot like REM sleep cycles seen in humans.

Other animals, including some birds and mammals, have been shown to experience REM sleep. But creatures like the jumping spider haven’t gotten as much attention so it wasn’t known if they got the same kind of sleep, said Roessler, an evolutionary biologist at the University of Konstanz in Germany.

Biologist: ’It was just the most unusual thing I’ve ever seen’
