Mini microchip raises hope of tiny computer
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 breakthrough in microchip technology has opened up the prospect of computers that are hundreds of times smaller and more powerful than existing models.
Scientists have made a transistor that is roughly a million times smaller than a grain of sand, using a single layer of carbon molecules – a feat that could one day lead to the development of "organic" computers that could communicate directly with the human brain.
Never before have scientists been able to build a transistor – the basic on/off switches within a computer's electronic circuit – from a single layer of molecules. Hendrik Schon, who led the research team from the Bell Labs at Lucent Technologies in New Jersey, said organic computers made out of carbon chips rather than silicon could be built within 10 to 15 years.
The discovery meant that thousands of times more transistors could be packed on to each microchip.
One of the possible benefits of the study, which is published today in the journal Nature, is that the brain – whose circuits are carbon-based – will eventually be able to control computers by thought alone.
