Snakes are known for their iconic S-shaped movements. But they have a less noticeable skill that gives them a unique superpower.

Snakes can crawl in a straight line.

University of Cincinnati biologist Bruce Jayne studied the mechanics of snake movement to understand exactly how they can propel themselves forward like a train through a tunnel.

“It’s a very good way to move in confined spaces,” Jayne said. “A lot of heavy-bodied snakes use this locomotion: vipers, boa constrictors, anacondas and pythons.”

His study titled “Crawling without Wiggling” was published in December in the Journal of Experimental Biology.

This is fascinating, and in other news: find yourself a man who looks at you the way Dr Bruce Jayne looks at snakes.

Did giant mushrooms rule the Devonian land?

As the first land plants colonised the land around the early Devonian period (419 to 359 million years ago), and the tallest trees were only a metre high, enigmatic fossils up to 8 metres tall and 1 wide were the globe’s largest surface organism, and possibly largest life form. These fossils, found worldwide and called Protoaxites, have puzzled palaeontologists since their first discovery in 1843.

Octopus and squid evolution is officially weirder than we could have ever imagined

Just when we thought octopuses couldn’t be any weirder, it turns out that they and their cephalopod brethren evolve differently from nearly every other organism on the planet.

In a surprising twist, scientists have discovered that octopuses, along with some squid and cuttlefish species, routinely edit their RNA (ribonucleic acid) sequences to adapt to their environment.

This is weird because that’s really not how adaptations usually happen in multicellular animals. When an organism changes in some fundamental way, it typically starts with a genetic mutation - a change to the DNA.

The findings have been published in Cell.
