Into the photic zone: does a darkening ocean threaten marine life?
5 June - 14 minsVast areas of the ocean are getting darker, according to research based on satellite imaging. Marine ecosystems are governed by faint light changes – from mass nightly migrations to coral spawning cycles – so what happens when that light begins to fade? Ian Sample talks to Prof Tim Smyth from the Plymouth Marine Laboratory about why this darkening is happening and how life in the ‘photic zone’ – the sunlit upper layer that is home to 90% of marine organisms – could be profoundly affected Planet’s darkening oceans pose threat to marine life, scientists say.

The extraordinary promise of gene editing
Doctors in the US have become the first to treat a baby with a customised gene-editing therapy after diagnosing the child with a severe genetic disorder that kills about half of those affected in early infancy. Ian Sample explains to Madeleine Finlay how this new therapy works and how it paves the way for even more complex gene editing techniques. David Liu, a professor at the Broad Institute of MIT and Harvard and the inventor of these therapies, also describes the barriers that could prevent them reaching patients, and how he thinks they can be overcome.
