Summary
Today, you’ll learn about a new groundbreaking bionic leg, the problem with first impressions, and new tech that can detect microplastics in water in milliseconds.
Bionic Leg
- “Bionic leg makes walking quicker and easier for amputees, trial shows.” by Hannah Devlin. 2024.

- “Agonist-antagonist Myoneural Interface (AMI).” MIT Media Lab. N.D.
- “Continuous neural control of a bionic limb restores biomimetic gait after amputation.” by Hyungeun Song, et al. 2024.
First Impressions
- “How first impressions can trap us into making suboptimal decisions.” by Eric W. Dolan. 2024.
- “Missing out by pursuing rewarding outcomes: Why initial biases can lead to persistent suboptimal choices.” by Chris Harris, et al. 2023.
Nanoplastic Detection

| 0:44.9 | you're new we are so excited to have you here with us today I'm Cali. |
| 0:48.0 | Today you'll learn about a new groundbreaking bionic leg the problem with first impressions, and new tech that can detect |
| 0:55.9 | microplastics in water in milliseconds. I'm excited for these, let's jump in. |
| 1:00.4 | In the United States alone there are well over 2 million people living with the loss of one or more of their limbs and while it's difficult to know exactly which limbs are the most commonly amputated, some say it's likely that most of those amputations involve legs. |
| 1:15.0 | In fact, some 70% of all prosthetic limbs are below the knee prosthetics. |
| 1:19.0 | Leg prosthetics have come a long way over the years, but here's the thing. |
| 1:23.0 | Even with hydraulic, spendable joints, motors, and carbon fire composite rods, |
| 1:27.0 | prosthetic legs still basically work on the same principle as they're wooden predecessors. |
| 1:32.0 | They're a tool that you can attach to a portion of your |
| 1:34.0 | leg that allows you to approximate walking. I guess I'd never really thought about it like that. |
| 1:39.1 | Like a prosthetic isn't a leg exactly but more of an approximation of one that allows for mobility. |
| 1:46.0 | And again, there's no denying that they are wildly more advanced than ever before. |
| 1:50.0 | But there's still a missing piece to the prosthetic puzzle and a team of researchers at MIT thinks they may have found it. |
| 1:56.9 | They have developed a brain-controlled bionic leg that enables amputees to walk faster and |
| 2:01.8 | navigate stairs and other obstacles way more efficiently |
| 2:05.5 | just by using their thoughts. |
