epigenetics

Scientists report that biological changes can be passed down through many generations without any alteration to the DNA sequence itself, pointing to epigenetic mechanisms that carry traits beyond genetic code. The finding adds to ongoing debate about how much of inheritance depends on DNA alone, and what it means for evolution and disease research.

A scientific journal has launched a new section examining epigenetics through the lens of ethics and society, according to Bioengineer.org. The section is framed as putting the field 'on trial', weighing how epigenetic research intersects with questions of responsibility, social policy and scientific interpretation. The report drew little visible engagement so far, but signals growing editorial interest in the social implications of epigenetics.
