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...


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...


Biology students who participated in a one-on-one homework activity with a classmate showed increased learning gains. The huge sizes of many undergraduate science courses make...


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...
