Micro insects

I haven't been feeling up to writing much lately. Most of my free time has been occupied with working on an academic project in meta-genomics. I'm aiming for this to be published in a science journal, so I won't be discussing the details of it here (for now). I'm also experiencing some anxiety surrounding what my job currently is, where it is going, and where I want it to go.

All together, this is leading to a pretty solid writer's block. I've got a collection of interesting topics that I haven't managed to pull together into full posts, so I'll probably be posting a few of these over the next several weeks. Today, I want to point you towards some readings about extremely, bizarrely, tiny insects.

Micro-wasp with aneucleate nerves
Micro beetle.
Features found in both micro-insects.
  1. Reduced number of neurons, but a relatively larger nervous system.
  2. Reduction in number of organ parts. Reduction in Malpigian tubules, spicules, etc.
