A Wnt protein involved in the formation of the human ovary plays an important role in female zebrafish sex development.    Even though zebrafish are...


An opportunistic human pathogen makes itself at home on old oaks. At one point or another, most people have played host to the common yeast...


The gene Ade2 links metabolism and sleep in the fat bodies of Drosophila. All animals need to eat and sleep. In fact, these critical behaviors...


Machine learning and access to ever-expanding databases improves genomic prediction of human traits. In theory, a scientist could predict your height using just your genome...


Parent-of-origin effects help determine how lab rats respond to stress. Although your father and mother each contribute a copy of your genes, these copies don’t...


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...

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...
