there's so much bad in the world but there's also people who lift up and carry an elderly bat around every day so he can pretend he's flying again, and that's the part of the world I think is worth fighting for

Ugh I did neuro and have seen instances where E is the least important person on the paper AND where E and F are co-supervisors.

Australia's 10 most dangerous snakes Australia is known for its dangerous snakes, and we have many – but in reality few people die from bites. Here are Australia's most dangerous snakes.

Absolutely adore this Australian Geographic article that describes the coastal taipan (one of the most venomous snakes in the world) as "extremely nervous." Like, me too, buddy. πŸ§ͺ

When someone says β€žScientists do not want you to knowβ€œ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

Urinary concentrations of a direct ethanol metabolite indicate substantial ingestion of fermenting fruit by chimpanzees Abstract. Frugivorous animals routinely ingest fruit sugars and the associated products of microbial fermentation. Yeast-derived ethanol within fruit is a

Out of 20 chimps, 17 males and females tested positive for EtG ("above a clinically meaningful cutoff")

Researchers suggest further investigations into the effects of alc consumption on chimps' intergroup aggression and the timing of estrous.

"Urine from individually identified chimpanzees was collected opportunistically and non-invasively using a pipette from fresh and dry leaf litter. Chimpanzees predictably urinate just prior to leaving a fruit crop and can often be seen preparing to do so by climbing to a lower branch of a tree."

To show that the chimps were actually consuming the ethanol (& not somehow choosing the lowest-alcohol fruits to eat), researchers measured EtG, an alcohol metabolite, in their pee.

How did they collect pee from wild chimps?? you ask. I had the same question & luckily the methods section explains:

Urine tests reveal "substantial" consumption of ethanol by wild chimpanzees.πŸ§ͺ
Previously, researchers assessed ethanol levels in ripe fruits & how much of these fruits the chimps typically ate to estimate that they consumed ~1.5 drinks a day. BUT directly demonstrating alc consumption was trickier.

The strange animals that control their body heat Some creatures can dramatically alter their internal temperature β€” a strategy called heterothermy β€” and outlast storms, floods and predators

In humans, body temperature is strictly controlled, deviating only a degree or two from the standard 98.6 (although today's average human temp may actually be slightly lower), but many mammals are more flexible. I loved learning about heterothermy in lots of weird little mammals for this piece πŸ§ͺ🦊

While searching for a bird evolution paper, I came across @currentbiology.bsky.social's amazing Quick Guide to Bird Genitalia. In my mind a quick guide is like how to change a tire, so I love the idea of an emergency requiring immediate instruction on bird genitalia. Don't @ me ornithologists πŸ§ͺ

In the summer, they never observed this behavior, but in winter, poo-eating happened in more than half of "events." Since natural food resources are scarce in the winter, this may help the choughs get more nutrition or help their gut microbiomes adjust to human food sources (bird feeders & garbage)

These birds eat poop, but only sometimes. Why?
Poop-eating, or coprophagy, is super common in the animal world, but it's not well understood in birds.

Evaluating inhibitory control in captive raccoons (Procyon lotor) using the cylinder task - Learning & Behavior Inhibitory control is an executive function that allows humans and non-human animals to suppress a prepotent response and continue in goal-directed behavior when outcomes are delayed.

Delightfully, the researchers have included videos of the raccoons in the paper's supplementary information:

this could be due to raccoons' high levels of persistence, which contributes to their problem-solving abilities, but may be linked to worse performance in inhibitory control. Research on raccoons and other city species helps reveal the cognitive skills that facilitate adaptation to urban life.

This puts them in the middle of the pack among the species tested so far - they're much better than chicken, but not nearly as good as a chimp. This was somewhat surprising to researchers since raccoons generally perform well in other tests of behavioral flexibility. Researchers hypothesized that

That contained a jumbo marshmallow. They had to suppress the impulse to go right for the treat (since they couldn't get to it through the plastic) and instead had to reach down with their lil hands to grab it through the top of the tube. The raccoons did... just okay, passing about 60% of the time.
