Microfluidic systems redefined biology by providing platforms that handle small fluid volumes, catalyzing advancements in cellular and molecular studies.
The Sloan Kettering researcher used mutagenic screening to probe genes and molecular pathways, including Toll and Hedgehog, essential to development in fruit flies and mice.
Immunoglobulin genes might have evolved much earlier than previously expected, perhaps even in the common ancestor of Cnidarians and Bilateria, a study suggests.
