my favorite feature is that it's a smart device—you connect it with your phone via proprietary app and it tells you the temperature of your counter top. Also for a low monthly subscription fee it will also recite the screen play of a random episode of friends in 4 languages simultaneously, none of which are English, Spanish, Arabic, or Mandarin.

Let's unpack this.

Do you mean that convicted baby-eater and Facebook founder Mark Zuckerberg, who died 17 days ago at the age of 153, had rat's penis transplanted onto him?

Or do you mean that Mark Zuckerberg, sole founding member of Rat Penis Enthusiasts' Quarterly, had a rat transplanted onto his penis?

I'm asking because the details matter in these trying times.

Adding to this: XX and XY works for mammals, but not for other vertebrates (fish, birds, reptiles, amphibians). Birds and reptiles have Z and W chromosomes, and unlike in mammals where females are homozygotes, males in these groups are homozygotes. Some reptiles have temperature dependent sex determination, where ambient temperature above some value will produce males or females (depends on species). Some reptiles are composed entirely of females.

Some fish will straight up change sexes depending on age and male-female ratio in a social group.

In other groups it's not even different chromosomes but simply copy number of specific genes.

Plants can do all sorts of whacky things like produce seeds and pollen in the same individual.

Fungi are an entirely different cluster fuck because they have mating types which are not simple binaries.

Eukaryotic sex determination isn't a binary and it isn't even a nicely categorizable spectrum. It's a grab-bag of whatever doesn't perma-fuck your genome.

Source: me, I'm a biologist. Though admittedly I work on animals so my understanding of fungi and plant stuff is fuzzy at best.

Hemipenes (and penis/intermittent organs) are really diverse in terms of size and shape. A lot of lizards and snakes have little nodules and barbs that vary from species to species. Not sure what the ornaments do, but it's interesting. Also interesting is that having two (i.e. one on each side) potentially means that there's a handedness in terms of the preferred side used for mating.

Other fun facts about penises and other intermittent organs: cats and other felids have barbed penises that force ovulation in the female. Tangentially related are the pseudo penises of female hyenas.

More fun facts: damselfly males have intermittent organs that are spoon shaped so they scrape out the sperm of rival males.

Respond 'cock facts' to learn more about penises and intermittent organs.

Respond 'stop' if you don't want to learn cool shit.

Not always—it depends on the publisher for sure, and possibly the field (e.g., physics, chemistry).

In biology, you have several models for peer review. Completely blind reviews where both reviewers and authors are anonymized. You also have semi blind models where the reviewers know the identities of the authors, but the authors don't know reviewers' identities. You also have open reviews where everyone knows one another's identities.

In completely blind and semi-blind models, you occasionally have reviewers that reveal their identity.

This is my rock. There are many like it, but this one is mine.

The otter in the OP is a river otter (probably american river otter)—I'm like 90% sure they do not have pockets. The otter in the comment is a sea otter (in case the watermark didn't give that away)—they have skin folds that's often described as pockets near-ish to the armpit.

Neither of them are marsupials—they both belong to the family Mustelidae (which also include badgers, weasels, etc).

Following this metaphor, I see it as: US Left: car's in neutral on a steep incline, foot is off the brake and they aren't sure if they're moving backwards or everyone outside is moving forward. Regardless they think they're doing a great job.

Center: same as above but they're complaining that everyone outside is going too fast that they may have even gone past their destination.

Right: same car, same place, but the car's in reverse and the foot is on full throttle. The center is still complaining about the speed but they're enjoying the view. The US Left is now fully aware of the backwards movement but it doesn't want to take the seatbelt off for the sake of self preservation at the cost of everyone else outside. The rest of the world is either steering clear or has been reversed in to like in one of rear-end insurance scams.

What's your favorite unbelievable fact?

I'm going to qualify this—all vertebrate eyes have a blind spot. Cephalopods also have eyes that are like vertebrates (this type of eye is called 'camera eyes'), but their eye anatomy is such that no blind spot exists for them.

Piggybacking on your fact about the brain effectively editing what we visually perceive, we don't see our nose (unless you made a concerted effort to look at it) because the brain ignores it.
