Creation of synthetic yeast genome nearly completed
Scientists are close to creating synthetic yeast and could have it completed by the end of this year. The artificial genome has been completely designed and is about one-third complete, and once constructed, […]

DNA-based computer could solve problems faster
A theoretical DNA-based computer called a nondeterministic universal Turing machine could work out difficult problems faster than both conventional and quantum computers. The machine works by endlessly rearranging DNA via gene editing.
