Ebola virus evolution tracked by genetic data
Analysis of Ebola genomes shows how the virus has evolved and some of the mutations that may thwart treatments.

Tiger swallowtail genome gives clues to insect’s stinky defense
Clues within the genetic code of the Eastern tiger swallowtail butterfly (Papilio glaucus) explain how it developed a smelly defense against predators.

Ancient East Asians mixed and mingled multiple times with Neandertals
East Asians’ ancestors interbred with Neandertals more than once, explaining why modern East Asians carry more Neandertal DNA than Europeans do, two studies suggest.

The genetic evolution of Darwin’s finches
A genetic analysis divides Darwin’s finches into more species and uncovers a gene involved in determining beak shape.

Baby brains undergo dramatic changes in utero
Developing human brains experience more than 28,000 changes in a molecular process that governs gene activity.

Pregnancy in mammals evolved with help from roving DNA
DNA that “jumped” around the genome helped early mammals shift from laying eggs to giving birth to live young.
- Science & Society
Big data studies come with replication challenges
As science moves into big data research — analyzing billions of bits of DNA or other data from thousands of research subjects — concern grows that much of what is discovered is fool’s gold.
