The year 2023 has seen incredible science around the world - including some very weird and wacky findings.

Here we look back at some of the most amazing studies from researchers and scientists unveiled during the last 12 months.

They range from zombie bird drones to frogs naturally disguised as poop.

Researchers developed quirky drones made from the bodies of dead birds, all the better to aid wildlife monitoring by blending in a natural environment.

Meanwhile, a newly discovered frog species was observed to mimic bird droppings, an evolutionary camouflage tactic to evade predators.

Among unique body enhancements is a quirky navigation aid that directs walkers by shocking their feet.

Elsewhere, Jizai Arms were unveiled as a robotic limb system that can be attached when needed, with robo-arms able to be exchanged between friends.

Astronomers are making huge leaps in exploring the universe with the James Webb Space Telescope. However, one of the most head-scratching sights was a distinct question mark shape in a pair of actively forming stars 1,470 light-years away.

In the realm of nature, revelations emerged that starfish possess all head and no body, bottlenose dolphins navigate oceans using an electric super sense, and rebellious Dutch birds construct nests out of anti-bird spikes.

Other notable innovations saw bioengineers growing skin in the shape of hands, while researchers are improving the beer brewing process by having mini robots swim around in it.

And finally, who could fail to chuckle when the star of a live stream of a rocket launch was a photobombing sloth?
