Jenny Graves has spent her life mapping genes and comparing genomes. Now she’s created a musical opus about evolution of life on this planet — bringing the same drive and experimentalism she brought to the study of marsupial chromosomes.
More than 70 years ago, mathematician Alan Turing proposed a mechanism that explained how patterns could emerge from bland uniformity. Scientists are still using his model — and adding new twists — to gain a deeper understanding of animal markings.
Some make nests inside seashells, others tote bubbles of air on their backs. The spiders that went back to water evolved lots of slick survival strategies.
With the first medical therapy approved and systems like CRISPR-Cas showing up in complex cells, there’s a lot going on in the genome editing field. Here’s our primer.
They have held our fascination ever since we first identified their remains. Today, thanks to new artifacts and technologies, findings about our closest relatives are coming thick and fast.
Scientists agree that eons ago, a bacterium took up residence inside another cell and became its powerhouse, the mitochondrion. But there are competing theories about the birth of other organelles such as the nucleus and endoplasmic reticulum.
Social insects and humans share the trait of divvying up tasks, as do some fish. Researchers find that it emerges naturally, and it often doesn’t take a boss to keep things in order.
PODCAST: Archaeopteryx forever changed our understanding of dinosaurs and the origin of birds, but it took a century after its discovery and a one-page paper to shift scientific consensus (Season 3, Episode 2)
Bt crops keep many agricultural pests at bay and have drastically reduced the use of pesticides. But scientists warn that these valuable tools are in jeopardy due to overuse and abuse.
Ecologist Sandy Milner has traveled to Alaska for decades to study the development of streams flowing from melting glaciers. He’s seen insects move in, alders and willows spring up, and spawning fish arrive in thousands.
Some researchers suspect these bacterial ancestors living within our cells may contribute to a wide range of neurological and psychiatric disorders
