Hey @Tusky , please could you make it so you remember where I was in the timeline when I accidentally double back right out of the app about 50 times a day. Thank you.
@RememberUsAlways Sorry. My weakness is sometimes not buttoning my lip. It's just when there's actual text in an image it seems the minimum to include. I think the web interface does OCR.
Big news in bug math. This is the first year since 1803 when both 13-year cicadas and 17-year cicadas will emerge from the ground simultaneously in the US!
13 and 17 are both prime. It's believed cicadas evolved to have prime-number life cycles, thus avoiding predators that emerge more frequently, like once every 4 years or 5 years or... whatever. By showing up infrequently, with a prime number life cycle, cicadas can starve out those predators.
And since 13 and 17 are both prime and 13 × 17 = 221, both kinds of cicadas emerge simultaneously only once every 221 years. And
1803 + 221 = 2024
so now they'll both emerge simultaneously and we'll have 𝑙𝑜𝑡𝑠 of cicadas!
Also, this year the two kinds can interbreed! Maybe they're be fruitful and multiply... and we'll get 221-year cicadas. 😆
The last time the Northern Illinois Brood’s 17-year cycle aligned with the Great Southern Brood’s 13-year cycle, Thomas Jefferson was president.
@johncarlosbaez My hunch would be that it's not the primeness per se that outsmarts the predators. Rather just the long, fixed period with there being something in the genes that makes those numbers easier to code.

There was a young singer called Rick
Whose rise to great fame was quite quick
His success came so fastIy
With music so ghastly
That he soon got on everyone's wick.
I love the excitement of seeing a new world for the first time. Yesterday, NASA's Lucy Mission flew past an unexplored asteroid named Dinkinesh. Today, it sent back images showing that Dinkinesh is a double asteroid!
@coreyspowell Fascinated to see gravity working at small scale.The NASA article says the images are taken 13 seconds apart. Orbit radius maybe 1km if compared with the body sizes given? I make it 5 shots (~1min) to do about half an orbit (unless it does more than a whole orbit each time). 3km/min=50m/s (180km/h). Could fairly easily estimate their densities.
End of days sogginess here right now. BBC weather site showing only three hours without a rain icon in the next more than 200. two hundred hours of rain! #Brighton
Scientists build traps to manage the UK’s rising number of Chinese mitten crabs.
The Chinese mitten crab was first sighted in the UK in 1935. Since then its population has exploded.
It is classified by conservationists as one of the 100 worst invasive alien species in the world. Now, a group of scientists are hoping they have found a way to deplete the UK’s rapidly growing Chinese mitten crab population.
@TheEuropeanNetwork "The Chinese mitten crab, so-called because it originated in south-east Asia"
Err, and also because it seems to be wearing a ruddy great pair of mittens.
