DNA can store information for millions of years without any energy input, but scientists have lacked reliable energy sources to enable DNA computations. Credit: Kateryna Kon/SPL Researchers have found a new way to power DNA computers — tiny biological devices that perform calculations using biochemical properties of DNA bases rather than conventional silicone chips, which use electricity to carry out …

Scientists have created egg-like cells capable of fertilization using DNA from ordinary skin cells in what could be a major breakthrough for infertility research. Using a newly developed technique to remove excess chromosomes, a team led by clinical biologist Nuria Marti-Gutierrez of Oregon Health & Science University has created human eggs that can undergo successful fertilization and start to develop …

James GallagherHealth and science correspondent OHSU/Christine Torres Hicks US scientists have, for the first time, made early-stage human embryos by manipulating DNA taken from people’s skin cells and then fertilising it with sperm. The technique could overcome infertility due to old age or disease, by using almost any cell in the body as the starting point for life. It could …

When a woman becomes pregnant, the outcome of that pregnancy depends on many things — including a crucial event that happened while she was still growing inside her own mother’s womb. It depends on the quality of the egg cells that were already forming inside her fetal ovaries. The DNA-containing chromosomes in those cells must be cut, spliced and sorted …

Scientists have been using ancient DNA to investigate questions about extinct animals since 1984, when researchers recovered two pieces of DNA from a museum specimen of a quagga, a zebra-like species that went extinct in the 19th century. Over the past 40 years, advancements in technology have allowed scientists to sequence older and older DNA from animals and plants, with …

Mitochondria (illustration) have their own DNA, which they expel into their environment if the molecules don’t meet their standards.Credit: Kateryna Kon/Science Photo Library The cellular batteries known as mitochondria sometimes dump DNA into their surroundings, which can contribute to inflammation during ageing. Now a study in mice reveals why this dumping occurs: mitochondria are expelling ‘tainted’ DNA1. Scientists found that, …
