Holiday Images: Genetic Mismatch
Haomin Huang • Fox Chase Cancer Center

Like bright berries on a holly bush, proteins (red) attach to chromosomes being pulled apart by microtubules (green). Hover over the image to the next slide, though, and our perfect holiday image blurs because of mutations in an enzyme that helps control proper chromosome segregation. More...

Fertility Trait Determined by piRNAs
Gregory Hannon • Cold Spring Harbor Laboratory

We usually think of biological traits as stemming from DNA, but a new study shows that fertility in flies depends on another, maternally inherited factor. More...
