Nanotechnology just got a little bit smarter.
At the Institute of Nanotechnology and Advanced Materials at Israel’s Bar-Ilan University, Ido Bachelet led a team of scientists in building tiny robots that can respond to chemical cues and operate inside a living animal. More than that, they can operate as logic gates, essentially acting as real computers.
That gives the nanobots — on the order of nanometers, or one-billionth of a meter — the ability to follow specific instructions, making them programmable. Such tiny robots could do everything from target tumors to repair tissue damage.
The experimenters used a technique called “DNA origami” to make the robots. DNA comes in a double-helix shape, making long strings. And like yarn, the strings can be linked together to make different shapes. In this case, the researchers knitted together DNA into a kind of folded box with a lid, a robot called an “E” for “effector.” The “lid” opened when certain molecules bumped into it.

Best Easter picture book ever. So many childhood memories.
I loved this book. I have vivid memories of being madly in love with these illustrations. That egg was the greatest thing in the universe at the time.
K, You know that project that I said I was working on for you? The one that I said I was going to have to take classes for so I could finish? I’m still going to have to do that, but I was going to give you a snippet of it for Today, but then I realized that I didn’t have enough data to do a decent job.
So all you get is this.
(Also, this is why I feel bad for the people sitting behind me on rollercoasters…)
I’m trying to think of a clever way to explain how delighted I am at the idea that you would need to take more classes to finish a project for me. I am failing. But trust me, I am delighted. Also, that there is currently insufficient data.
Next time we ride a rollercoaster together, then, I fully expect you to begin singing “Yes, Captain Hammer’s here, hair blowing in the breeze…”
"…if you’d look at how he related to everyone — Coulson loves projects. Here is a guy who didn’t have people skills. So Garrett says, can you help this guy Ward round off some of the rough edges? So he comes onto the team. Coulson is now vested, because he’s got a project. Who is Ward’s greatest threat? May. What does he do? He seduces her. Who is the one unknown on the team? Skye. He becomes her S.O. How do you get everyone rally around and trust you? You jump out of a plan trying to save someone else. Now, he had a parachute. Let’s say he failed to save Simmons, he would’ve been fine. Everything he’s done has solidified how people feel about him over the course of the season."
"…what was the next thing he had to do after he saved Simmons? He had someone on the plane who was jealous of him: Fitz. And what did they do? They went on a mission together and they had a really good time together. And a bromance was started. And that took care of that." x
"…then in "Seeds," there’s a really nice moment where Skye is standing at the wall of valor, and we hear Coulson’s voice off-camera saying that the world is full of evil, pain, lies and death — and the camera pans and lands on Ward when he says "lies" and "evil."" x
