The dinosaurs were really, really unlucky. As if getting struck by a 10km-wide asteroid wasn’t bad enough, the terrible lizards were virtually wiped out by the global climate change that followed – but only because of where the giant space rock landed, according to new research. Matthew Wills explains how the precise location of the impact was a crucial factor in the dinosaurs’ demise and the eventual rise of humanity.
Twitter’s decision to extend the length of tweets to 280 characters has attracted a lot of criticism, including from Harry Potter creator JK Rowling, who tweeted that “the whole point, for me, was how inventive people could be within that concise framework”. Academic and novelist Catherine Wilcox also enjoys crafting perfectly edited tweets but believes there’s a whiff of elitism about insisting on brevity for brevity’s sake.
Lord Robert Winston told a reporter on the BBC’s Today programme that freezing human eggs for later use is “extremely unsuccessful”. We asked two fertility experts, John Appleby and Sarah Martins da Silva, to check the facts.
