But though Scientific American has been providing in-depth protection of the coronavirus pandemic, devastating natural disasters and the presidential election’s implications for science, we have also shared stories that exhibit how the enjoyment aspect of science nonetheless thrives. Listed here, we’ve collected some of our favorites from the 12 months, from the certainly wonderful to the downright strange and quirky. We hope you appreciate them and arrive back again for much more coverage of slicing-edge science in 2021.
Combat! Battle! Fight!
Acorn woodpeckers fiercely protect territories of granary trees stuffed with provides, and when a vacancy opens up, rival groups swoop in to combat for it. Biologists delight in looking at these types of fierce spectacles, but they are not the only ones—other acorn woodpeckers rapidly master of the fights, and they fly in from kilometers away to observe the motion.
Robo-Curler Receives in South Korean Athletes’ Hair
AI is quite fantastic at chess and Go. It’s the serious earth, and the problem of translating a simulation to fact, that throws a robot for a loop—until now. A robot named Curly gained three of 4 games towards major human rivals from South Korean curling groups.
Amphibians Would Make Great Ravers
Some frogs and other amphibians activity bright shades and placing designs, while many others have a drabber visual appearance. But it turns out many of them are hiding a secret that was uncovered when scientists turned on blue and ultraviolet lights: They glow. Technically talking, they biofluoresce. We really do not know why, but just one chance is to entice mates (presumably with out the EDM).
Voice of the Lifeless
Sophisticated imaging techniques support researchers study historic continues to be, these types of as the 3,000-12 months-previous mummy of an Egyptian scribe, without the need of damaging them. But why just glance when you can pay attention? Experts used CT scans to graphic the mummy’s vocal tract, 3-D print a duplicate and operate air via it, therefore resurrecting the corpse’s voice.

A Snack-Bag’s-Eye View

I Consider, Hence I Am Section of a Simulation?
Is truth authentic? Or are we unwitting individuals in a computer simulation, à la The Matrix? A study this yr set the odds either way at 50–50. So have enjoyable bending your brain all around that one for a though.
Kentucky Fried Pheasant?

Blow Out the Candles, Hubble!
