Международная группа исследователей проанализировала и описала механизм полета микронасекомых — мельчайших жуков из семейства перокрылок. Оказалось, все дело в облегченных крыльях и особом стиле полета.
Миниатюризация — уменьшение размеров тела животного в процессе эволюции — одно из основных направлений эволюции насекомых, в процессе которого они могут уменьшиться до размеров одноклеточных организмов. При этом таким микронасекомым удается сохранить сложное строение и поведение и даже приобрести уникальные характеристики.
В 2020 году группа исследователей из МГУ обнаружила, что некоторые виды из семейства перокрылок (лат. Ptiliidae) способны преодолевать 975 длин собственного тела в секунду — на сегодня это самая высокая относительная скорость среди всех животных, для которых измерен такой показатель.
Кроме того, перокрылки не уступают по развиваемой скорости втрое более крупным представителям родственных групп жуков и развивают большее ускорение, чем на порядок более крупные жуки. В чем их секрет, исследователи из МГУ и Сколтеха совместно с коллегами из Германии и Японии решили выяснить на примере одного из самых маленьких жуков-перокрылок Paratuposa placentis, длина тела которого составляет всего 395 микрометров.
Жуков для изучения отлавливали во Вьетнаме, а затем помещали в специальный бокс и снимали их полет на две высокоскоростные видеокамеры. На основе видео ученые создали трехмерную реконструкцию движения крыльев, надкрылий и тела насекомых. Это позволило провести точные аэродинамические расчеты. Строение крыльев анализировали с помощью сканирующего электронного и конфокального лазерного микроскопов.
Исследование показало, что секрет быстрого полета перокрылок — в строении крыльев и траектории их взмахов в виде широкой восьмерки. Узкая крыловая пластина крыла перокрылок обрамлена по периферии длинными щетинками, выполняющими ту же функцию, что птичьи перья. В результате крыло п

AITA for demanding that my son's stepdad pay for the Xbox he threw in the pool? >That man is abusive. Get the custody agreement changed, and take your ex's husband to small claims if he doesn't pay up. I would also go to the police and rapport the damages done to the Xbox so you have a paper trail. > >Protect your son. NTA

That’s weird. Any ideas on what this is? >This is Lycogala epidendrum or a related species, a plasmodial slime mold and not a fungus. It would be more accurate to simply call it Lycogala as ID is actually quite complicated. The genus contains over 20 species but only has 2 that are identifiable as individual, while the rest look like this, more or less, and all of them have been considered Lycogala epidendrum historically and traditionally. > >Anyway, plasmodial slime molds (I call them slimes) are in the genetic supergroup Amoebozoa with other amoebas like Amoeba proteus and Arcella. Fungi are in the genetic supergroup Obazoa with the animals, which means Tony award winning Broadway lyricist, composer, an...

... keep reading on reddit ➡I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.
Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.
I guess the concept didn't work
Alot of great jokes get posted here! However just because you have a joke, doesn't mean it's a dad joke.
THIS IS NOT ABOUT NSFW, THIS IS ABOUT LONG JOKES, BLONDE JOKES, SEXUAL JOKES, KNOCK KNOCK JOKES, POLITICAL JOKES, ETC BEING POSTED IN A DAD JOKE SUB
Try telling these sexual jokes that get posted here, to your kid and see how your spouse likes it.. if that goes well, Try telling one of your friends kid about your sex life being like Coca cola, first it was normal, than light and now zero , and see if the parents are OK with you telling their kid the "dad joke"
I'm not even referencing the NSFW, I'm saying Dad jokes are corny, and sometimes painful, not sexual
So check out r/jokes for all types of jokes
r/unclejokes for dirty jokes
r/3amjokes for real weird and alot of OC
r/cleandadjokes If your really sick of seeing not dad jokes in r/dadjokes
Punchline !
Edit: this is not a post about NSFW , This is about jokes, knock knock jokes, blonde jokes, political jokes etc being posted in a dad joke sub
Edit 2: don't touch the thermostat
Do your worst!
How the hell am I suppose to know when it’s raining in Sweden?
Ants don’t even have the concept fathers, let alone a good dad joke. Keep r/ants out of my r/dadjokes.
But no, seriously. I understand rule 7 is great to have intelligent discussion, but sometimes it feels like 1 in 10 posts here is someone getting upset about the jokes on this sub. Let the mods deal with it, they regulate the sub.

Now that I listen to albums, I hardly ever leave the house.
Don't you know a good pun is its own reword?
Two muffins are in an oven, one muffin looks at the other and says "is it just me, or is it hot in here?"
Then the other muffin says "AHH, TALKING MUFFIN!!!"
For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.
I said "hey look, an escaPEA"
No one near me but it didn't half make me laugh for a good hour or so!
Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂
It really does, I swear!

Heard they've been doing some shady business.
but then I remembered it was ground this morning.
Edit: Thank you guys for the awards, they're much nicer than the cardboard sleeve I've been using and reassures me that my jokes aren't stale
Edit 2: I have already been made aware that Men In Black 3 has told a version of this joke before. If the joke is not new to you, please enjoy any of the single origin puns in the comments
They’re on standbi
