The cats graciously put on a magic show for us last night. I figured out how they did most of the tricks, but I didn’t say anything, because that would have been rude.
Two cats on a platformed tower. One is on the lower level, head hidden behind the middle section. The second is on the top tier with only their head showing.

While my hair is hanging in there, I'm of the age where my social media feeds get targeted ads for hair loss products, e.g. Amazon's #1 bestselling "Nutrafol" As I study host-pathogen interactions, I wondered what other immune cell-themed grooming products might be envisioned .. Any other ideas?

A #ROADRUNNER I came across this AM It's the world's fastest bird also capable of flight: top ground speed = to that of Usain Bolt The "racing stripe" on its cheek with a vivid mix of dark blue, white, and bright red-orange is actually a patch of bare, featherless skin rather than colored feathers

It hunts by pouncing on prey, wrapping its dozens of legs around the target, and injecting a potent neurotoxic venom that paralyzes and kills its meal. It's bite is extraordinarily painful to humans as this thrillseeker(?) video shows:

Hiking near Donghaksa in Gyeryongsan National Park, Korea, I came across this GIANT ASIAN CENTIPEDE (Scolopendra subspinipes), a species can grow 8 to 10+ inches long. It is an APEX PREDATOR that feeds on insects, spiders, and scorpions, as well as small vertebrates like lizards, frogs, and mice.
