Microfluidic systems redefined biology by providing platforms that handle small fluid volumes, catalyzing advancements in cellular and molecular studies.
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.
Distantly related, lookalike Heliconius species arrive at the same appearance using the same few genes, but regulated differently, according to recent studies.
A single gene called BMP11 regulates not only the size and proportions of a water strider’s massively long third legs, but also how it uses the limbs in fights.
