Koalas and Crime Scenes
Here’s a wild one for your next trivia night: koalas have fingerprints that are nearly identical to humans. Seriously, if you put a koala and a human fingerprint under a microscope, even the most seasoned forensic scientist might scratch their head in confusion. These furry eucalyptus enthusiasts developed dermal ridges so similar to ours that they’ve actually been considered a potential crime-scene contaminant in areas where koalas roam. Imagine the plot twist: your DNA clears you, but the police have a koala in custody. “It wasn’t me, officer; I’ve been framed by a cute marsupial!”
What’s even crazier is that scientists believe this fingerprint similarity evolved independently in koalas, likely to help them grip trees and munch on leaves with precision. For doctors, it’s a fascinating reminder of how nature can converge on similar solutions for completely different reasons. In humans, fingerprints serve to enhance touch and dexterity; in koalas, they help ensure their eucalyptus feast stays firmly in paw. Either way, it’s hard not to appreciate how evolution pulled this sneaky, CSI-worthy trick. Who knew our furry friends might one day outfox us in the world of forensic science?

Never Push Paralytics, Unless...
Hot take, but I believe healthcare providers should only use paralytic medications for rapid sequence intubation if they can also perform a surgical airway. This is because I know that first-pass intubation isn't always successful, and if I can't ventilate the patient due to an upper airway issue or similar problem, a surgical airway is essential. Waiting for help isn't good enough in such a critical situation. While I understand my stance is controversial, I'd like to hear your thoughts, particularly when ventilation is impossible after giving paralytics.
