Eye movements in Drosophila. Flies have two retinal muscles per eye, which can generate optokinetic reflexes and small saccades. Each eye can perform these movements independently.

Proposed structure for the mechanotransduction complex that detects sound and head motion in the vertebrate inner ear. Studies used an equivalent protein complex in C. elegans (where it detects light touch). 60,000,000 worms yielded 50 ng of protein.

Fortunately, there is an official standard for pigeon-based Internet Protocol: RFC 1149. It has also been actually implemented with real pigeons! (At 0.08 bps, but still)

But wait: this paper shows pigeons carrying memory cards can reach 28 gigs per sec! https://t.co/WpNEASLMJu

The first single cell RNA-Seq characterizations of the avian cochlea establish some genetic bases for cellular identity in this fascinating structure. Excellent papers.

From NYT:

"The E.P.A. has proposed allowing as much as 650,000 pounds of streptomycin to be sprayed on citrus crops each year. By comparison, Americans annually use 14,000 pounds of aminoglycosides, the class of antibiotics that includes streptomycin."

A new Twitter account that tracks media reports of medical studies that were conducted on mice, but written as though the outcomes apply to humans. It’s been active only two days, but already has nearly 7,000 followers.
