Your support helps us to tell the story

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.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

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.

After months of trials, a contender for the title of World's Strongest Insect was named by scientists today.

The dung beetle species Onthophagus taurus can pull a load 1,141 times its own body weight - the equivalent of an average person pulling six fully laden double decker buses.

Dr Rob Knell, one of the researchers from Queen Mary, University of London, said: "Insects are well known for being able to perform amazing feats of strength, and it's all on account of their curious sex lives.

"Female beetles of this species dig tunnels under a dung pat, where males mate with them. If a male enters a tunnel that is already occupied by a rival, they fight by locking horns and try to push each other out."

Dr Knell's team tested the ability of beetles to resist a rival by measuring how much force was needed to pull them from their holes.

The findings are published in the journal Proceedings of the Royal Society B.

Dr Knell said: "Interestingly, some male dung beetles don't fight over females. They are smaller, weaker and don't have horns like the larger males. Even when we fed them up they didn't grow stronger, so we know it's not because they have a poorer diet.

"They did, however, develop substantially bigger testicles for their body size. This suggests they sneak behind the back of the other male, waiting until he's looking the other way for a chance to mate with the female. Instead of growing super-strength to fight for a female, they grow lots more sperm to increase their chances of fertilising her eggs and fathering the next generation."
