Australia’s iconic marsupial has been viewed as a food source, pest, mascot and, now, a conservation concern. Scientists are breaking down myths — using genetics, robots and citizen science — and finding new ways to protect the animals.
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.
Polygenic risk scores — a patient’s chance, based on tiny DNA variants, of developing cardiovascular disease, breast cancer and more — are coming to clinics. But there are kinks to iron out and accuracy remains an issue.
As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? Key controls happen well before replication even starts.
Researchers are investigating medicines that selectively kill decrepit cells to promote healthy aging — but more work is needed before declaring them a fountain of youth
The beloved animal has shaped human history over millennia, just as people have influenced its evolution — but only recently have scientists discovered exactly when and where it went from wild to tame
Researchers helped mice stay mighty with an experiment to counter the effects of microgravity. The gene treatment might also enhance muscle and bone health on Earth — and in humans.
Scientists are finding that microscopic membranous bubbles called extracellular vesicles transmit messages from cells and do big jobs in many areas of biology — plus they might be useful for therapies.
The cryobank is a rich source of genetic knowledge of hundreds of creatures. It may one day be used to bring endangered species back from the brink and deepen the gene pool of wild populations.
Five new things we’re learning about the extinct animals and their ancient kin
