Depending on which study you look at, research suggests that e-cigarettes are both good for your health because they stop you smoking cigarettes, or bad – or at the very least potential harms are yet unclear. So what’s the truth? Should smokers be using them to help kick the tobacco habit? Or do they pose a risk in themselves? Sarah Mitchell, Martin Clift and Shareen Doak explain the latest.
The evidence that there could be life on Mars after all seems to be getting stronger every day. Now, a surprising new study shows that briny water below the planet’s surface can contain molecular oxygen – meaning it could support microbial life or even simple animals like sponges. Andrew Coates writes about what it all means for space exploration.
Theresa May’s former aide Nick Timothy suggested that the UK prime minister needed to “discover her inner Boudica”. Surely that’s a terrible idea, says Martha Vandrei. While the ancient British queen’s fighting spirit has long been summoned by politicians, her battle ended in bloody slaughter at the hands of the Romans and is a warning to all those tempted to become embroiled in party in-fighting while their country’s future hangs
precariously in the balance.
