How a Protein “Cancer Cop” Targets UV Damage in DNA

Wednesday, June 4th, 2014 | Tags: , , , ,

Ah, summer. People are outside enjoying the warm weather, swimming, playing, or just soaking up that glorious, skin-damaging, high-energy UV radiation from the sun. We know that prolonged sun exposure damages skin – the sun is a nuclear reactor, after all. But how does our body respond to and repair this damage at the DNA

Small Number of Genes Have Big Impact on Fish Egg Quality

Thursday, May 15th, 2014 | Tags: , , , ,

NC State researchers have taken a big step toward solving a puzzle that has long vexed vertebrates – predicting egg quality, or the viability of embryos in eggs. Using gene expression data and computer modeling, the researchers examined farmed striped bass (Morone saxatilis) and showed that the coordinated interactions of less than 2 percent of

Living in extreme environments often entails taking extreme measures to survive. Live-bearing fish mothers in toxic North and South American waters try to give their offspring the best chance at surviving the harsh environment by giving birth to big babies, according to research published in Ecology Letters. The study examining nine different live-bearing fish species
