Sperm can “age” independently of the male, when stored in male or female reproductive tracts. Our meta-analysis finds widespread evidence across animals (including abstinence in men). Important consequences for fertility, sexual selection, haploid selection!

I need to remember to use this instead of my fandom account more

(I'm pretty sure I know what the confounding factor is, but still. Man)

Indeed. I myself am autistic, and my life has only improved after my late diagnosis, as it's thrown a lot of my world into context. I've gained a great deal of help from the online autistic community.

However, as a researcher, it's an absolute pain in the ass.

Wow! Where was this specifically? I'd love to walk over and see if I can spot them after work

Illustrated image divided into four panels, each showing a head of a bat with a text label. Top left: little guy, a regular looking back with a dark face and light colored fur, top right: little guy deluxe, a bat with a mask and large ears alongside a bat with a leaf shaped nose, bottom left: what is even going on here, a visored bat with a large forehead next to a bat with a large, wrinkly nose, bottom right: o hi doggie, a fruit bat with its tongue sticking out.

Contrary to popular belief, there are only four kinds of bats.

A wooly chafer beetle depicted lying on its side. Unusually for a beetle, it has teats and is nursing three grubs.

Three panel black and white comic. Panel 1. A smiling eel-like primitive fish shows off it's new iPhone in front of it to two trilobites. Fish dialogue: check out my new phone! It's got 16 gigabytes it can hold! Trilobite dialogue: oh yeah? How many trilobites can it hold? Panel 2: the fish looks on, concerned, as the two trilobites crawl onto the phone and others join. Panel 3: the fish looks upset, its phone is buried in several trilobites. Fish dialogue: please stop

A realistic tiger beetle illustration against a beige canvas texture background. The beetle has a mostly white abdomen with a brown stripe down the middle, its thorax and head are iridescent green. It has large, jagged mandibles and fairly thin long legs, as well as fur on its underside. Text: Utah's most special guy.

Utah's most special guy, the Coral Pink Sand Dunes tiger beetle, only occupies a 1800m x 300m area in the state park of the same name. This guy is NOT going places!

A black and white image depicting a skinny wide-eyed hair nibbling on a patch of flowers. Below it, engulphed in dark soil, is a mirror image of a hair skeleton. The roots of the plant tangle around its jaws.

OPABINIA ENCOUNTER

A smiling chubby cartoon quail sits in an ornately decorated Christmas sweater wearing a little Santa Claus hat. He is holding a mug and some worms striped to look like candy canes. In front of him are a cactus with a bow and a scorpion wearing a festive hat.

Commission for a friend. Merry Quailsmas! (The scorpion is named Sandy Claws btw)

Just found out there's a group on Inaturalist, "Observational Comedy" dedicated to showing only the silliest observations

Lower image: Round isopod with angel wings and a halo labeled "innocent cinnamon roll-y poly" on the left end of a sliding scale, followed by two somewhat round isopods, and a very flat pointy isopod with a devil's pitchfork labeled "flat freak friday" to the right.

Just making sure that everyone is aware of this crab that NOAA scientists found

A white, semitransparent isopod with a bright purple drink. The purple drink is partially visible though the isopod's body as it consumes it. It is surrounded by mosses and lichen.

Five isopods on an old, lichen-covered log. Caption reads: Isopod culture.

An isopod in sunglasses skateboards down a log cut to look like a ramp. A crowd of isopods wearing sunglasses and caps cheer it on. Caption: isopod counterculture.

A pill bottle tipped over with its lid off, letting its contents, live isopods, spill out. Some are fully curled while others crawl around. Text: I've got a pill problem.

An illustration of an anthropomorphic mouse woman and her offspring. Upper left she is in a hospital gown with frizzy unkempt hair, holding her five pink hairless newborns in her arms. Lower right her children have open eyes and thin fur, her arms are full with three of them while the other two crawl and tumble around her feet.

A close up painting of a rhino beetle, a large shiny black beetle with a powerful horn, illuminated from the back. It is crawling over a craggy piece of bark with a hazy forest behind it.

Rhino beetle oil painting from a while back. I need to do more oil painting...

A dazzling bird with iridescent green, blue, and gold plumage perches on a delicate branch adorned with soft lichen. Its feathers shimmer in the light, displaying an intricate mosaic of colors.

Panel 1 of a three panel comic. An isopod digs at a pile of dirt, text: scrape scrape.

Panel 2: The isopod digs more quickly, a human arm with tattoos and a spiked bracelet emerges from the soil. Text: dig, dig, accompanied by a speech bubble "Mph!"

Panel 3: The isopod stands next to three radical rock stars poking up from the ground. Rock star dialogue: Gasp! Thank you, A. Vulgare! Being trapped underground for weeks was putting mad strain on the band! Isopod dialogue: No problem, Isopods are great at removing heavy metal from soil.
