Ancient viral DNA helps human embryos develop

00:50 How ancient viruses drive modern human development

Research suggests that ancient viral-DNA embedded in the human genome is playing a key role in early embryo development. Around 8% of our genome consists of endogenous retrovirus DNA — the remnants of ancient infections, but knowledge of their activity is limited. Now, a team show that these sequences are required for the correct development of lab-derived embryo analogues, and for the switching on of human-specific genes.

13:05 How heat can fuel DNA computers

Researchers have developed a way to use heat to recharge DNA-based computer circuits, which could help overcome one of the stumbling blocks preventing this technology from being scaled up. Although DNA strands have been used to perform computational tasks for some time, current methods can run out of energy or build up waste products, preventing their continued use. Now, using just heat a team have demonstrated a reuseable neural network based on DNA. They hope that ultimately this could be a step in the development of bigger and more powerful DNA computers that could be used to power targeted clinical therapies.
