Carnivorous Caterpillars

Carnivorous caterpillars lurk between spider strands in Hawaii. The newly identified species disguises itself with spare body parts.

  • Species name = bone collector

  • Scavenges webs to craft the perfect cloak

  • Only found in the Wai'anae Mountains

Bone collectors grow solely from spidey leftovers before metamorphosing into an otherwise typical moth. Our time to enjoy/fear these mini-carnivores may be short lived as they appear close to extinction. No bones about it.

Hmm...

Which is the better caterpillar costume?

Gold-in Eye

Injecting gold into your eye could protect your vision. Researchers are developing a nanoparticle to shield light-induced damage.

  • Act as micro-filters to shield photoreceptor cells

  • Compatible w/ eye tissue thanks to silica coating

  • Reduced light exposure-vision loss in mice

Stabbing your eye with gold may seem drastic, but researchers compare the procedure to gene therapies which can be harder to scale. Before you update your ID to reflect your new “gold” eye color, human trials are not yet in sight.

Nocturnal Pink

Owls are pink! That is, if you see in ultraviolet.

  • Pink pigment = porphyrin

  • Especially prominent after molting

  • Degrades when exposed to sunlight

Scientists haven’t confirmed if owls can perceive the shades of pink, though UV communication has been observed in other bird species. Future research will determine how prevalent pink perception is among the wise birds. What a hoot!

Last week: “What does the dolphin say??”

33% squeak, 67% click

Some may say “squeak” was wrong. But in the industry, we call this a “right click”.
