Listen to this recording. It sounds a little like Sputnik, but it's actually a noise that's not been heard in 165 million years.
This is the song of an extinct species of bush cricket, the fossils of which have been found in China's Inner Mongolia region. Researchers recreated the sound by studying the fossil remains of the crickets' sound-producing organs. From the BBC:
A "plectrum" on one wing was dragged along a microscopic comb-like structure on the other. This produces a continuous "chirp" as the male insects rub, or "stridulate" their wings in a scissor-like motion. Dr Zapata described this stridulation as similar to playing a tiny violin.
Dr Zapata then set out to calculate the frequency of the tone, which denotes how high- or low-pitched it sounded. To to this, he simply compared the size and shape of its music-making or "stridulatory" instruments to those of living cricket species
There are modern bush crickets, but their songs are played at a higher pitch. The low tones produced by this extinct cricket imply that it might have been best adapted to do its singing on the ground, rather than elevated on branches or tall stalks of grass. Lower pitched sounds travel further from that elevation than a high-pitched one would.

In the year 2,000, Susan Potter, then 72, donated her body to medicine. After Potter died, scientists froze her corpse, sliced it into 27,000 slivers thinner than a human hair, photographed each slice, and created “the world’s most advanced virtual cadaver using the highest-quality imagery of an entire human body in existence.” Not only is […]
Leon Hong writes, "I made this science-y animation for my wife Elaine Hsiao's research — with the hopes that people will learn something new about how all the microbes that live in and on us affect our brains and behavior."
Everybody’s flown a paper airplane. But what if you could fly on a paper airplane? Until we invent shrink-ray technology, the PowerUp X FPV Video Paper Airplane Kit will have to do – but it’s as fun as that sounds and more. The original version of this creative toy added drone tech to the old, […]
Adobe’s design software catalog is essential to any graphics program, as much for their simplicity as their versatility. Anyone can be an effective graphic designer with tools like Illustrator and InDesign – and the right training in their potential. That’s where the Adobe CC A-Z Lifetime Bundle comes in. Whether you’re getting your feet wet […]
Businesses of any size continue to use PDFs despite – and perhaps because of – their stubborn resistance to simple editing. But for those who need a little flexibility on their documentation, the search is over for alternative software. PDF Expert for Mac is the catch-all solution for wrangling those PDFs, and it’s available at […]
