Professor Jürgen Englert describes the aging process. It’s known that genes play a crucial role but there are several other factors at play too.
US regulators have approved a breakthrough treatment that genetically engineers patients' own blood cells to fight childhood leukemia. Experts say it may open the way to treating other cancers with a similar procedure.
Researchers in the US have used an experimental gene-editing technique to correct a mutation in dozens of embryos. Some hailed the development as illuminating and surprising; others say it crossed a moral line.
Harvard researchers have taken a step closer to implanting pig organs in humans by using gene-editing to clone piglets free of harmful viruses. The CRISPR genetic splicing process remains controversial, however.
An FDA advisory panel has unanimously approved a leukemia treatment that could become the first gene therapy approved in the US. The panel hailed the drug as a "major advance" in the battle against childhood cancer.
