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.

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 metal-eating earthworm that can survive the toxic environment of heavily contaminated soils is being recruited in the fight to clean up the polluted land of former industrial sites.

Scientists believe earthworms have undergone rapid evolutionary changes at abandoned mines in Britain, which have enabled them to survive and even thrive in an environment rich in toxic heavy metals. The researchers hope it may be possible to breed the worms and distribute them around contaminated sites in the hope they can help rid the soil of heavy metals.

"A combination of laboratory, field and synchrotron X-ray experiments have led to the finding that metal-tolerant populations of super earthworms are evolving," said Mark Hodson of the University of Reading.

Earthworms can consume 30 times their own body weight each day and the super worms ingest large quantities of potentially toxic metals such as arsenic, lead, zinc and caesium, Dr Hodson told the science festival.
