A small, seemingly unremarkable fern that only grows on a remote Pacific island was on Friday crowned the Guinness World Record holder for having the largest genome of any organism on Earth. The New Caledonian fern, Tmesipteris oblanceolata, has more than 50 times more DNA packed into the nucleus of its cells than humans do. If the DNA from one of the fern's cells -- which are just a fraction of a millimeter wide -- were unraveled, it would stretch out to 106 meters (350 feet), scientists said in a new study. Stood upright, the DNA would be taller than the tower that holds London's famous Big Ben bell. The fern's genome weighed in at a whopping 160 gigabase pairs (Gbp), the measurement for DNA length. That is seven percent larger than the previous record holder, the Japanese flowering plant Paris japonica.

"The world's coral reefs are close to 25 percent larger than we thought. By using satellite images, machine learning and on-ground knowledge from a global network of people living and working on coral reefs, we found an extra 64,000 square kilometers (24,700 square miles) of coral reefs – an area the size of Ireland.
That brings the total size of the planet's shallow reefs (meaning 0-20 meters deep) to 348,000 square kilometers – the size of Germany. This figure represents whole coral reef ecosystems, ranging from sandy-bottomed lagoons with a little coral, to coral rubble flats, to living walls of coral.
Within this 348,000 km² of coral is 80,000 km² where there's a hard bottom – rocks rather than sand. These areas are likely to be home to significant amounts of coral – the places snorkelers and scuba divers most like to visit.
You might wonder why we're finding this out now. Didn't we already know where the world's reefs are?
Previously, we've had to pull data from many different sources, which made it harder to pin down the extent of coral reefs with certainty. But now we have high resolution satellite data covering the entire world – and are able to see reefs as deep as 30 meters down.
Pictured: Geomorphic mapping (left) compared to new reef extent (red shading, right image) in the northern Great Barrier Reef.
[AKA: All the stuff in red on that map is coral reef we did not realize existed!! Coral reefs cover so much more territory than we thought! And that's just one example. (From northern Queensland)]
We coupled this with direct observations and records of coral reefs from over 400 individuals and organizations in countries with coral reefs from all regions, such as the Maldives, Cuba, and Australia.
To produce the maps, we used machine learning techniques to chew through 100 trillion pixels from the Sentinel-2 and Planet Dove CubeSat satellites to make accurate predictions about where coral is – and is not. The team worked with almost 500 researchers and collaborators to make the maps.
The result: the world's first comprehensive map of coral reefs extent, and their composition, produced through the Allen Coral Atlas. [You can see the interactive maps yourself at the link!]
The maps are already proving their worth. Reef management agencies around the world are using them to plan and assess conservation work and threats to reefs."

Errors, “Errors,” and Sci Fi
@strawberry-crocodile
tvtropes calls stuff like the wolf example "science matches on" which I think is a pretty fair shake
This. This is what’s got me thinking so much about errors. There’s a certain danger, here. A certain way that this particular effect — delicious dramatic irony — tempts the mind when reading old stories, even true ones.
What do you know about R.M.S. Titanic? I ask my class every year, and the first hand rises. “It was unsinkable,” the student inevitably says, and everyone is nodding, “or so they thought.” I write the word UNSINKABLE on the board, underneath my crude drawing of a ship with four smokestacks. It will be crossed out before the end of the hour, but not for the reason they expect.
“I find no evidence,” Walter Lord, preeminent biographer of the ship’s survivors, wrote, “that Titanic was ever advertised as unsinkable. This detail seems to have entered the collective mind so as to create a more perfect irony.” Indeed, historians’ examinations of White Star Line documents show the shipbuilders themselves worried it would be so large as to risk collision; they stocked several more lifeboats than 1910s regulations required.
The War to End All Wars (deep breath, satisfied exhale), also known as World War ONE. Chuckle. Shake of the head. What if I told you that this phrase, used primarily in American newspapers after the fact, wasn’t meant to be literal? Nowadays we’d say The Mother of All Wars, or One Hell of a Fucking War, but we wouldn’t mean literal motherhood, literal intercourse. ��What if I said the armistice and the Lost Generation and the Roaring 20s were all braced for another outbreak of European conflict, and yet we still failed to prevent it?
Did you know they were so confident in the safety of the S.S. Challenger that they put a civilian schoolteacher onboard? I do, because I’ve heard that one repeated many times. Only, see, it’s got the cause and effect reversed. Challenger launched on a day the shuttle’s engineers knew to be dangerously cold, because the first civilian in space was on board. And NASA knew its shuttle project would be cancelled entirely, if they couldn’t get that civilian’s much-delayed entry into space in the next two weeks. So they launched on a cold day, and killed her instead.
These are all what cognitive science calls Hindsight Bias on the personal level, what sociology calls Presentism on the cultural level. Social psychology’s a little of both, is primarily interested in why you’re sitting on your couch in a Colonize Mars shirt watching PBS and chuckling at the fools who believed in El Dorado. It wants to know why the mind flees straight from “marijuana will kill you” to “marijuana will cure cancer” without so much as a pause on the middle ground of its real benefits and drawbacks, its real (mild) risks and rewards.
And they can paralyze the sci-fi writer, if you think too much about them. Jetsons is futurist one decade, retro the next. “There are no bathrooms on the Enterprise,” the creators of Serenity say smugly, as if Gene Roddenberry should’ve simply known that decades later it’d be acceptable to show a man peeing in full view of the camera, nothing but the curve of the actor’s hand to protect his modesty. “No sound in space,” the Fandom Menace says, “No explosions in space,” and “A space station can’t collapse in zero-G.” Only then NASA burns a paper napkin outside of atmosphere, transmits music using only the ghost of nearby planets’ gravities, and logs onto Reddit long enough to point out the Death Star would implode in its own gravity field. And now we’re the ones pointing, the ones laughing, at those earlier point-and-laughers. Self-satisfied, smug in superiority. As if we did the work to find out ourselves, instead of just happening to be born a little later than George Lucas.
#errors#continuity#sci fi#presentism#star wars#titanic#world war i#science marches on#history#started a new post because i got waaaaaay off topic here#if you think the dinosaurs in Jurassic Park (1993) should've had feathers#you're a lot more ignorant about paleontology than the people you're trying to criticize#science was not handed down to us in its perfect complete form circa 1943#stop for a second before you call out someone else's reptilian denonychus#someone else's oxygenated moon#and ask: am i better read#or am i just more recently born?

Happy Resonance Cascade Day, Cave Johnson is laughing at Black Mesa from beyond the grave
#He would so roast Breen for being the combine’s puppet and black mesa for doing science that really messed up the world#He’s like “sure I’m a horrible bastard but I didnt open a portal that let aliens take over the earth”#“Or be the figurehead for humanity’s new miserable existence”#“Resonance cascade. You’re supposed to be scientists!”#Portal#portal 2#Cave Johnson#Black Mesa#Half-life#hl#half life#Resonance cascade

Well, we now have evidence of parthenogenesis in birds *and* crocodiles. That forms the phylogenetic bracket around non-avian dinosaurs. Any nonavian - any dinosaur - could have undergone parthenogenesis under the right conditions. We can officially get rid of the frog dna.
