With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.
Stem cells in culture; engineered cancer biomarkers; small molecule improves stem cell homing; reproducible bacterial evolution; how human adaptive immunity develops
Water bears can survive extreme temperatures, oxidative stress, UV radiation, and more, but as work in climate change biology shows, they’re not invulnerable to everything.
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
DNA passed to and from all kinds of organisms, even across kingdoms, has helped shape the tree of life, to a large and undisputed degree in microbes and also unexpectedly in multicellular fungi, plants, and animals.
