Awww Cougars, like this youngster from the Oregon Zoo, start life spotty. They eventually grow in to the sleek golden mountain lions (Puma concolor) we're all familiar with. While they can certainly be dangerous, cougars far prefer to avoid humans altogether.😮 These could be the oldest known tattooing tools! ✏️ They're made from turkey bones from as far back as 3500 BCE. Tattooed ancient American remains date back to over 5,000 years ago, suggesting the practice was rather common. 📷 Deter-Wolf et al, J Archaeol Sci Rep, 2021ESA’s Mars Express reveals details of Mar's Pyrrhae Regio. ☄️️ The objects that created the impact craters (left) also flung hot molten rock into the air, which landed and cooled into the scar-like features present nearby (right). :😍 Far-infrared light reveals magnetic fields in galaxy NGC 1068, aligning along the entire 24,000 light years of length of its massive spiral arms - suggesting gravitational forces that created the galaxy’s shape are also compressing its magnetic field. 📸 :This 50p coin celebrates self-taught paleontologist Mary Anning. Discovered by Anning in 1828, the Dimorphodon was the first pterosaur skeleton to be found outside of Germany. :Ghostly blue chromosomes are joined by green kinetochores to supporting red spindles that will drag each of the duplicate genetic molecules into opposite directions, to be encased into newly formed cells, during cell division. 📷 Jane Stout/Indiana University/ZEISS MicroscopyThese river dolphins are playing with an anaconda!

Entiauspe Neto/Steffen Reichle/Alejandro dos RiosPeople trust nonsense from scientists even more than spiritual gurus - a phenomenon called the Einstein Effect. Researchers found participants were more likely to believe nonsense statements it told they were said by a scientist.

The Cartwheel Galaxy, 500 million light-years away, likely owes its striking, spiraling nautilus shell shape to a collision with a smaller galaxy. https://t.co/srKDIQQtNp 📷 NASA/ESA/CSA/STScIThis revolting weirdo carries its own poop on its back Poop backpacks are not uncommon for leaf beetle larvae (Cassidinae). Some are still gooey, while others encase theirs like this one, for camouflage, or parasite deterrent purposes.  Gilles San Martin/Wiki/CC BY-SA 3.0Why was this horse buried without a head? 😱 It was found close by a skeleton buried for 1,400 years at an ancient cemetery in Germany. It's a little spooky, but the team haven't managed to find the head... Read more: https://t.co/igEszgVfkV 📷: F. DammingerHoney crystals look just as stunning as they tastes under 25 times magnification. Bees break down complex sugars in nectar and remove most water to produce a super-saturated liquid which is unstable, so over time the glucose in the solution crystallizes. 📷 Zeiss MicroscopyThis poor cormorant is covered in oil.

Maratus nemo is a newly discovered species of Australian peacock spider named for its dazzling orange and white coloration - reminiscent of clown fish.  : Joseph Schubert/@arachno_joeThis creepy fossil was called Hallucigenia, because it looks like, well, a hallucination. Many fossils were discovered without this head, which baffled scientists. Why were so many Hallucigenia getting decapitated?

Only about 0.25 mm long, they eat moss and algae. 📷 eyeofscience/InstagramLook mom, no hands!! 😆 This baby naked mole rat is somehow even more alien-looking than its parent. This little one was born in August, and can live up to 32 years - an incredibly long life for a rodent - so it'll have a long, exciting life ahead! 😱 📷:A new controversial study has suggested that these beads unearthed in Arctic Alaska may predate Columbus' arrival. 🤔 The researchers think that the beads were created in Venice and then traded eastward, ending up in what is now Alaska. 📷: Lester Ross/Charles AdkinsBaby Boudica is an endangered golden lion tamarin, a species vital for seed distribution and regeneration in the Atlantic Forest.

These cells eventually divide into different tissues that compose our complex airways. Visualizing them allows researchers to map how lungs grow. Casey Ah-Cann/@wehi_researchTrilobites scuttled along Earth's ocean floor in search for tasty carrion or prey, 530 to 252 million years ago. 🏹 This one, Cheirurus ingricus, was found in what's now Russia. It lived in during the Middle Ordovician period. 📷You're looking at a 1,200-year-old man with a knife for a hand. 🔪 The skeleton in question was found in a Longobard necropolis in the north of Italy, dating back to around the 6th to 8th centuries CE.
