Mind-Controlled Nanobots Used to Release Chemicals in Living Cockroaches

This is wild: a team of Israeli scientists developed a contraption that uses a person’s brain waves to remotely control DNA-based nanorobots  — while the nanobots were inside a living cockroach. When prompted by a human thought, the clam shell-like robots opened up, revealing a drug-like molecule that tweaked the physiology of the cockroach’s cells. Though “merely a demonstration and proof of concept,” the technology represents a new era of brain-nanomachine interfaces that links a… read more

How to Make Molecular Devices? Microscopic DNA Tools May Be Key

DNA codes for life as we know it, but in recent years, scientists have discovered more uses for the molecule. Because DNA is foldable and “sticky,” they’ve begun making microscopic shapes called DNA origami. Over the last decade or so, researchers have improved at this DNA art, and now, Caltech scientists say they used DNA to sketch a glowing masterpiece — a replica of Vincent van Gogh’s famous painting “The Starry Night”— on a canvas the size… read more

From Living Computers to Nano-Robots: How We’re Taking DNA Beyond Genetics

DNA is one of the most amazing molecules in nature, providing a way to carry the instructions needed to create almost any life form on… read more

Nanorobots: Where We Are Today and Why Their Future Has Amazing Potential

This post is a status update on one of the most powerful tools humanity will ever create: nanotechnology (or nanotech). My goal here is to give you a quick overview of the work going on in labs around the world, and the potential applications this nanotech work will have in health, energy, the environment, materials science, data storage and processing. As artificial intelligence has been getting a lot of the attention lately, I believe we’re going to start to see and hear about incredible breakthroughs in the nanotech world very soon. Origins of Nanotechnology Most historians credit the concept of nanotechnology… read more

How Scientists Are Hacking Biology to Build at the Molecular Scale

The long vision of nanotechnology suggests tiny robot “assemblers” will swarm unseen in the air, water, and even our bodies, building anything from the atoms up. It’s a wild thought and still (mostly) a dream. But looked at a bit differently, these nanoassemblers are already here, and we call them “life.” Basic organic machinery is ceaselessly pulling in raw materials and building (molecule by molecule) cells, organs, and bodies—from hearts to brains, ants to blue whales. Of course, we love to draw analogies between our inventions and the natural world. Today, DNA is software and our brains computers. These analogies help us visualize and even develop… read more

Exponential Medicine: The Most Advanced Nanotechnology Today Is Already Inside You

For me, the word nanotechnology evokes a specific image. Maybe you’re the same. It’s a machine. Perhaps a little futuristic. But something that wouldn’t seem out of place on the… read more

Can DNA Nanobots Successfully Treat Cancer Patient? First Human Trial Soon

“No, no it’s not science fiction; it’s already happening,” said Ido Bachelet to a somewhat incredulous audience member at a London event late last year. Bachelet, previously of Harvard’s Wyss… read more
