Programmed ribosomal frameshifting has translational costs that may influence codon usage bias. The genetic code has some redundancy—the same amino acid is often encoded by...


What inspired Mendel?

October 8, 2018

Newly uncovered newspaper articles shed light on Mendel’s motivations. Gregor Mendel is considered by many to be the father of genetics. Yet, because his work...


A new collection of inbred flies provides a tool for studying genetic control of sleep. Sleep is vital for a healthy life, but some of...


Low-cost sequencing closes gaps in fly genomes. Genetic sequencing technologies have revolutionized biological science, and regular advances in these tools continue to deliver better genomic...


Mitochondria on the mind

September 14, 2018

Mitochondria cell-autonomously regulate the secretion of neuropeptides in C. elegans. Neurons are hard-working cells that need a lot of energy to do their jobs, so...


Holes in the plasma membrane trigger the activation of the Torso receptor tyrosine kinase. As a general rule, cells don’t do well when holes are...


A new genome assembly for Antarctic fur seals sheds light on their historic comeback after 19th century hunting. In the late 19th century, the Antarctic...


Food-deprivation inhibits the stress-induced sleep response in C. elegans. For many animals, the essential physiological drives of sleep and food are intimately linked. You might...
