A team of Israeli scientists devised a system by which a person can use their thoughts alone to trigger tiny DNA-based nanorobots inside a living creature to release a drug.
The researchers from Herzliya's Interdirisplinary Center and Bar Ilan University previously developed origami-like nanorobots out of DNA that open their "gate" when exposed to electromagnetic energy. In the new work, a computer algorithm detected the change in a person's brainwaves when doing arithmetic and then switched on a magnetic coil trained on a cockroach that had been injected with the nanobots, causing the gates to open. From New Scientist:
The algorithm could be trained to track other types of brain activity, says Sachar Arnon, a member of the team at the Interdisciplinary Center. “It could track brain states that underlie ADHD or schizophrenia, for example. It could be modified to suit your needs.”
The idea would be to automatically trigger the release of a drug when it is needed. For example, some people don’t always know when they need medication – before a violent episode of schizophrenia, for instance. If an EEG could detect it was coming, it could stimulate the release of a preventative drug.
“People could take this in all different directions,” says Arnon. “Imagine if you could deliver the exact amount of alcohol that you wanted to keep you in a happy state but not drunk. Kind of stupid, but this could happen. I think we’ve just scratched the surface.”

Ebola is now a treatable disease.
Between 2010 and 2016, the FDA approved 210 new medicines and every single one was produced at public expense, part of a $1T US government investment project in medical research. Despite this massive public subsidy, the pharma industry has only grown more concentrated and rapacious, raising prices and diverting the profits to their execs and […]
Approximately 14 percent of the world’s population suffer from dry eye disease (DED) but treatments are limited because it’s difficult to model the complex human eye for drug development. Now though, University of Pennsylvania bioengineers developed an “eye-on-a-chip” complete with a motorized blinking eyelid. The hope is that the artificial eye will lead to a […]
If you’re marketing on the web, your Google-fu needs to be strong – and up to date. Without a firm grasp on what drives traffic, you’ll never be able to take the wheel. That’s why even if you know where to put your keywords, a little extra effort goes a long way on any marketer’s […]
Want to keep the dentist away? A little tooth care at morning and night isn’t bad, but it won’t keep the stains from smoking or fried foods at bay for long. If you enjoy your food and want to avoid the consequences, an upgrade from that old analog toothbrush can make a huge difference. Among […]
If your office works at all, it uses Microsoft Office. Those icons for Word, PowerPoint, and Outlook are as familiar around some workplaces as the coffee machine. So familiar, in fact, that they get taken for granted – and rarely used to their full potential. Whether you need a crash course in the essential tools […]
