Welcome to the Cool Stuff Ride Home podcast. Yes, this is a new episode. If you're listening, I suppose you might be wondering where we've been. Well, I apologize again for not being a better communicator here, but sometimes life happens and it forced us away from the mics

0:21.1

for a bit. We are back here with you now. And with all apologies to our detractors, this non-AI

human voices back with some more cool stories for you all to enjoy. Hopefully that is. So with that,

0:32.7

let's get right to it. Turning to ZME science and author Rupendra Brahambat. For decades above the knee amputees

0:41.1

have had to live with stiff, uncomfortable prosthetics that felt more like rigid tools than natural

0:47.3

limbs. As a result, climbing stairs, stepping over objects, or even just walking at a decent pace

0:53.3

becomes a constant struggle.

0:55.5

However, MIT researchers have developed a bionic knee so well integrated with the body

1:01.2

that users begin to feel it as part of themselves, not just mechanically but neurologically, too.

1:08.0

In early clinical trials, users with this new prosthesis walked faster, navigated obstacles more

1:14.4

naturally, and even reported a sensation of owning the limb as if it were truly their own.

1:20.2

Per Hugh Heurr, one of the researchers and a professor at MIT, quote,

1:25.5

a prosthesis that's tissue integrated, anchored to the bone, and directly

1:30.0

controlled by the nervous system is not merely a lifeless separate device. It's not simply a tool

1:36.0

that the human employs, but rather an integral part of self, end quote. This innovation could

1:41.8

mark a turning point in bionics, a field that is long promised

1:45.4

to life-like prosthetics, but often failed to match the human body's complexity. Now, the MIT team

1:51.5

developed a system called the Osseo-integrated mechanoneural prosthesis, or OMP, which is the result of

1:58.5

years of effort to restore not just movement, but the feeling of having a real leg again.

2:04.0

Traditional prosthetic limbs rely on sockets that wrap around the residual limb.

2:08.7

These sockets are often uncomfortable, can cause skin infections, and offer limited stability or control.

2:14.8

More importantly, they do not tap into the nervous system's natural signals,
