From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

A well-projected and energetic croak is the male frog's most important asset in the quest to attract mates to his pond, said a Melbourne University ecologist, Kirsten Parris. But competition from traffic noise in Melbourne could be why frog numbers have declined in Australia's second-largest city since her survey of more than 100 ponds began in 2000, she said. "If there are a number of different males calling, the one that sounds the best often gets the girl," said Dr Parris. "You have to be pretty clear about your assets if you're a male frog." Dr Parris found the distance at which a frog suitor can be heard by a potential mate is slashed by city noise.
