This is a flexible mesh circuitry that Harvard nanotechnologists have injected via syringe into the heads of live mice to test a new way of monitoring brain signals from the inside.
Eventually, such technology could lead to new treatments for Parkinson's disease or mind-controlled prosthetic limbs. From Smithsonian:
Autopsies of injected mice revealed that the wires had woven themselves into the tangled fabric of neurons over the course of weeks. Tight connections formed as plastic and brain matter knitted together with seemingly little negative impact.
The neurons’ activities could be monitored using microscopic sensors wired into the circuit. Voltage detectors picked up currents generated by individual brain cells firing. Those electrical signals were relayed along a wire running out of the head to a computer...
“We have to walk before we can run, but we think we can really revolutionize our ability to interface with the brain,” says (lead researcher Charles) Lieber.

Is your brain a machine? Are your thoughts and feelings just malware of the mind? (And what “really” is a machine, anyway?) John and Eva referee the transhumanist fight of the century. In the blue corner, we have Eva meeting founder and Bryan Johnson, CEO of Kernel, straight from his office in LA. And in […]
For some children with severe epilepsy, the best treatment may be a very rare surgical procedure in which a large portion — even half — of the child’s brain is removed or disconnected. Amazingly, many of these individuals can relearn motor, language, and cognitive skills. How? The brain reorganizes itself and builds new connections. To […]
This video depicts light speed in contexts where it appears to be slow. The moon is 1.2 light seconds from Earth; Mars several light minutes. This is, of course, why humans aren’t moving out of this solar system any time soon.
We all know those gifts we get “for the kids,” the ones that parents are secretly more excited to open. Drones are a perfect example, but there’s a model out there that really doubles down on that appeal. Introducing the Space Fighter Building Block Drones, a series of space fighter drones that are a blast […]
The hardest part of web design can be nailing down the look. These days, even non-designers can easily spot a stale stock photo or lazily-made icon. What’s the solution? No matter what kind of artist you are, it’s always a good idea to widen your palette. And with more than a million vector images to […]
For all that tech that gets squeezed into them, the best wireless earbuds are ones we barely have to think about. That’s the whole point, right? We get wireless because we just want to hit play and have a hands-free, cordless soundtrack for the rest of the commute. If that’s your philosophy, definitely give these […]
