So what is a #Supermoon? Well, the Moon is typically ~¼ million miles away (30 Earths in a row), but thanks to its elliptical orbit, that distance changes. Tonight the Full Moon is 2-Earths closer than normal (221,823 miles away), making it appear ~15% brighter than usual hence #Supermoon! 🔭🧪

Was delighted to discover this titbit about Tom Lehrer, the mathematician who put the chemical elements to music: (Original article here: www.economist.com/prospero/201...)
A screenshotted part of an article that reads: When 2 Chainz, a rapper, asked to sample “The Old Dope Peddler” in one of his tracks, Mr Lehrer was keen to help. “I grant you motherfuckers permission to do this,” he supposedly answered. “Please give my regards to Mr Chainz, or may I call him 2?”

Asian elephants work out we’re paying attention to them by observing how our face and body are oriented: www.nature.com/articles/s41... #scicomm 🧪
Two images sit side by side: one shows a TV screen with the word “Netflix” on it with a male viewer in the foreground and a brick wall in the background, while the other shows an advancing Asian elephant with vegetation in the background. Each has the caption: “big, long memory, knows when you’re watching”.

#OTD 19 September 1991, walkers in the high Ötztal alps on the Italian border, found a body melting out of the ice. It turned out to be the remains of a c.5200 year old man preserved with all his kit. Of course, it was essential to replicate him in Playmobil. 1🧵 #PlaymobilÖtzi #PlaymobilInfestation

#Onthisday in 1888, Bertha Benz took the first ever long-distance car journey. She solved snags as they arose, using a hat pin to clear a blockage, and replacing the brake blocks with leather, effectively inventing brake pads. More here: kicksfromscience.beehiiv.com/p/live-from-... #histsci

Hahaha! This preprint! 🔭🧪 Chance of event happening to you or the planet, and if so, chance it will be lethal? Turns out .... we are more likely to be hit by an impactor 140m and greater than: - being struck by lightning - getting killed by elephants and coyotes arxiv.org/abs/2508.02418
Plot that shows a one-in-X chance of an event occuring to someone or the planet over a human lifetime on x-axis and then the one in X chance of a fatality if that event occurs. Several events are plotted such as contracting rabies, influenze, being hit by a car, being attacked by a coyote or elephant, being struck by lighting, carbon monoxide poisinging and the Earth being struck by an impactor greater than 140m in diameter

What is common knowledge in your field, but shocks outsiders? Water is such a weird substance. Just absolutely bizarre. It's used as a standard or reference point for so much because it's so ubiquitous, but it's very different than pretty much every other liquid and every molecule of similar size.

Found a baby songbird? Here's a newly updated chart!
A chart that explains what to do If You Find A Baby Songbird Out Of The Nest. Is it hurt or did a cat get it? (Cat bites & scratches cause deadly infections.) or, Has a person kept it for over a day, given it food or water, or gotten it wet? If yes, Contact a licensed wildlife rehabilitator 
or wildlife care center near you. An online search can help. If no, what does it look like? Eyes not yet open. You have a hatchling. It's very young. Eyes open; feathers few & may be in tube-like sheaths. You have a nestling. Feathered; awkwardly hops or flutters; tail & wings short. You have a fledgling. Many sharp teeth; large claw on second toe. You have a velociraptor. If a hatchling or nestling, can you see the nest? If yes, Return it to its nest. The parents won’t care if they can smell you. If no, Make a nest from a basket & dried grass. Wire it to a tree. (Note: A few species, like Juncos, need a nest on the ground.) If a fledgling, is it in immediate danger? If yes, carefully move it to a safer spot nearby. If no, DO NOT INTERVENE! Though the bird looks awkward, it’s in a natural stage & the parents are still feeding it. If a velociraptor, has it seen you? If yes, back away slowly. Do not show fear. If no, run. Watch for others that may attack from the sides. FYI: Some babies (eg. swifts, most woodpeckers) only sit on the ground if in trouble. When in doubt, keep watch & contact a wildlife rehabilitator if needed!
