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.

Just for kicks, Paul Rule, 66, participated in a study launched by the Cambridge Natural History Society that enlisted citizen scientists and nature-lovers to help deepen knowledge of the flora and fauna in Cambridge, England. Rule recorded nearly 600 different animal species in his “ordinary” city garden, including an elephant moth like the one seen […]
Astronaut David Scott re-created, in 1971 during the Apollo 15 mission, Galileo’s “falling bodies” experiment by dropping a hammer and feather on the moon at the same time. Simply, both fell at the same rate because there was no air resistance. screengrab via Wonders of Physics/YouTube (Digg)

It’s impossible for anyone to truly escape the effects our COVID-19 lifestyle changes have made, but if you’re a web developer, there’s a decent chance your work life might be virtually unchanged. Even before the quarantines and work-from-home orders, over 16 percent of web developers were already self-employed. And with a growing number of tech […]
Even though life is emerging following our COVID-19 lockdown, it’s not exactly time to celebrate defeating the insidious virus just yet. CDC officials warn that once a resurgence of the virus hits this winter, it could prove even more disastrous for the U.S. healthcare system than the opening salvo. That would follow the pattern suffered […]
When you were 10 and your mom demanded you finish your vegetables or go to your room, you were mad. Even as kids, we hated it when we were ordered to do something. Car insurance is a federal mandate, yet that’s only one of the reasons why most Americans would rather do just about anything […]
