We can, must, and will simulate nematode brains (asteriskmag.com)
Scientists have spent over 25 years trying — and failing — to build computer simulations of the smallest brain we know. Today, we finally have the tools to pull it off.

Glutamate Unlocks Brain Cell Channels to Enable Thinking and Learning (neurosciencenews.com)
In an effort to understand how brain cells exchange chemical messages, scientists say they have successfully used a highly specialized microscope to capture more precise details of how one of the most common signaling molecules, glutamate, opens a channel and allows a flood of charged particles to enter.

10 Lizards were smuggled into Cincinnati in a sock. Now there are thousands (nationalgeographic.com)
For more than 70 years, thousands of common wall lizards, known as Lazarus lizards, from Europe have made Cincinnati their home. Even through record-low temperatures and snowfall, they’ve managed to survive—and multiply. But how did these Mediterranean reptiles gain such a foothold in a Midwestern city? It all started with a 10-year-old boy and a sock full of lizards.

The Biology of B-Movie Monsters (2003) (lib.uchicago.edu)
Size has been one of the most popular themes in monster movies, especially those from my favorite era, the 1950s. The premise is invariably to take something out of its usual context--make people small or something else (gorillas, grasshoppers, amoebae, etc.) large--and then play with the consequences. However, Hollywood's approach to the concept has been, from a biologist's perspective, hopelessly naïve. Absolute size cannot be treated in isolation; size per se affects almost every aspect of an organism's biology.

Plants can take up CWD-causing prions from soil in lab. What happens if eaten? (cidrap.umn.edu)
When Christopher Johnson, PhD, set out to study whether lab mice fed prion-contaminated plants developed neurodegenerative disease, he expected the plants to take up only small prion clusters, but they absorbed large clusters characteristic of prion diseases in deer and other animals.

The mysterious flow of fluid in the brain (quantamagazine.org)
Encased in the skull, perched atop the spine, the brain has a carefully managed existence. It receives only certain nutrients, filtered through the blood-brain barrier; an elaborate system of protective membranes surrounds it. That privileged space contains a mystery. For more than a century, scientists have wondered: If it’s so hard for anything to get into the brain, how does waste get out?
