Fly-sized robots aimed at surgery
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.

A prototype "millibot" is being built to see if scientists can miniaturise to the scale of a nanometre – a millionth of a millimetre – to build intelligent materials and microscopic machines.
James Ellenbogen of the Mitre Corporation told the association that the first insect-like robot – a motorised silicon chip with six legs – could be built by the end of 2004. "Once we decide on the right fit, I'd be pleased as punch if we had one next year that would scuttle across the table and avoid objects," he said.
The aim is to build computers that could fit on a grain of salt, composed of memory devices as small as a human cell. "We have prototype circuits for this, it is very real... The system we are building is a memory system. What we are really worried about is increasing the density of mass storage," said Dr Ellenbogen."What you would have done essentially is to shrink the memory of an old PC into the space of about eight human cells."
One of Dr Ellenbogen's aims is to design robots that could perform surgery within the human body.
