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.
Diverse lines of evidence point to humans’ presence in the New World long before the dawn of Clovis culture. But rewriting this chapter of human history raises many questions about how these early people came to inhabit these continents.
Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.
Researchers found the relatively high proportion of DNA from a hominin cousin—nearly 5 percent—when they scanned more than 1,000 genomes from 118 distinct ethnic groups.
Phylogenomics data place the enigmatic plankton in the middle of the algal family tree, despite their apparent lack of plastids—an organelle characteristic of all other algae.
