Researchers report that 'epigenetic' editing — altering gene activity without cutting DNA — can silence and eliminate hepatitis B virus. The approach targets the virus's genetic material in infected liver cells, raising hopes for a functional cure for the hundreds of millions living with chronic hepatitis B, a leading cause of liver cancer.

Epigenetic editing, which alters gene activity without changing DNA sequence, is reportedly approaching clinical application as bioengineering tools mature. Advances in gene-regulation technologies are making it feasible to target epigenetic marks precisely, opening the door to therapies for diseases rooted in gene expression rather than genetic mutations. The development signals a shift from laboratory research toward translational medicine, with researchers watching how safety and delivery challenges are addressed.
- 3AI reads chemical instructions guiding embryo cell development●AI can read the chemical instructions that tell embryo cells what to become
Researchers have developed artificial intelligence capable of interpreting the chemical signals, or epigenetic instructions, that determine what type of cell an embryo cell will become. The advance could deepen understanding of early development and birth defects, and raises ethical questions about how far AI should go in decoding the origins of human life.
