Scientists Develop ‘Cellular Glue’ That Could Heal Wounds, Regrow Nerves

One day, these special synthetic molecules could also help mitigate the organ shortage crisis.

Researchers from the University of California, San Francisco announced a fascinating innovation on Monday. They call it «cellular glue» and say it could one day open doors to massive medical achievements, like building organs in a lab for transplantation and reconstructing nerves that’ve been damaged beyond the reach of standard surgical repair.

Basically, the team engineered a set of synthetic molecules that can be manipulated to coax cells within the human body to bond with one another. Together, these molecules constitute the so-called «cellular glue» and act like adhesive molecules naturally found in and around cells that involuntarily dictate the way our tissues, nerves and organs are structured and anchored together.

Only in this case scientists can voluntarily control them.

«The properties of a tissue, like your skin for example, are determined in large part by how the different cells are organized within it,» Adam Stevens, a researcher at UCSF’s Cell Design Institute and first author of a paper in the journal Nature, said in a statement. «We’re devising ways to control this organization of cells, which is central to being able to synthesize tissues with the properties we want them to have.»

Doctors could eventually use the sticky material as a viable mechanism to mend patients’ wounds, regrow nerves otherwise deemed destroyed and potentially even work toward regenerating diseased lungs, livers and other vital organs.

That last bit could lend a hand in alleviating the crisis of donor organs rapidly running out of supply. According to the Health Resources and Services Administration, 17 people in the US die each day while on the waitlist for an organ transplant, yet every 10 minutes, another person is added to that list.

«Our work reveals a flexible molecular adhesion code that determines which cells will interact, and in what way,» Stevens said. «Now that we are starting to understand it, we can harness this code to direct how cells assemble into tissues and organs.»

Ikea cells

Right after babies are born (and even when they’re still in the womb) their cells essentially find it easy to reconnect with one another when a bond is lost. This is primarily because kids are still growing, so their cells are still actively coming together. But as a consequence, that’s also why their scratches and scrapes tend to heal quite quickly.

In other words, think of children’s cell molecules as having lots of clear-cut instructions on how to put themselves together to make tissues, organs and nerves. They’re like sentient little pieces of Ikea furniture with the store’s building booklet in hand.

As people get older, however, those biological Ikea instructions get put in the attic, the team explains. That’s because, for the most part, the body is pretty solidified — and this is sometimes a problem. For instance, when someone’s liver gets really damaged, their liver cell molecules may need to refer back to those Ikea instructions but can’t find them.

But that’s where «cellular glue» molecules come in. These rescuers can essentially be primed with those Ikea instructions before being sent into the body, so their blueprint is fresh. Scientists can load them up with information on which cell molecules to bond with and even how strongly to bond with them.

Then, these glue molecules can guide relevant cells toward one another, helping along the healing and regeneration processes.

«In a solid organ, like a lung or a liver, many of the cells will be bonded quite tightly,» explains a UCSF description of the new invention. «But in the immune system, weaker bonds enable the cells to flow through blood vessels or crawl between the tightly bound cells of skin or organ tissues to reach a pathogen or a wound.»

To make this kind of customization possible, the researchers added two important components to their cellular glue. First, part of the molecule acts as a receptor. It remains on the outside of the cell and determines which other cells the molecule is allowed to interact with. Second, there’s the bond-strength-tuner. This section exists within the cell. Mix and match those two traits and, the team says, you can create an array of cell adhesion molecules prepped to bond in various ways.

«We were able to engineer cells in a manner that allows us to control which cells they interact with, and also to control the nature of that interaction,» Wendell Lim, director of UCSF’s Cell Design Institute and senior author of the paper, said in a statement.

In fact, the team says the range of potential molecules is wide enough that they could inform the academic stage of medical studies, too. Researchers could make mock tissues, for example, to deepen understanding of the human body as a whole.

Or as Stevens put it, «These tools could be really transformative.»

I Got Up Close and Personal With Boston Dynamics’ New Atlas Robot

Before Atlas takes its first steps into the world of work later this year, I found myself face-to-face with CES 2026’s most talked-about robot on the show floor.

When I say that I went hands-on with the new Boston Dynamics Atlas robot, I mean that I actually held hands with it. This humanoid robot, which CNET just awarded the Best Robot of CES Award, is one of the most advanced in the world, and I couldn’t pass up the opportunity to get up close and personal with it.

This product version of the robot, which is set to be shipped to Hyundai factories imminently to start working, has been the talk of CES this year. The specific Atlas robot I encountered was a static model that wasn’t turned on or fully operational. Our interactions were, therefore, sadly one-sided. Still, I ran my hands over its soft-touch plastic shell and gently prodded at its finger joints, wondering how it would feel if they gripped me back.

People tend to have varying feelings about humanoid robots — understandable given that they are built to some degree in our image, while also usually being stronger than us, with «brains» that we don’t fully understand. Atlas definitely evokes contradictory emotions for me — even more so when I stood face-to-face with it.

I’m in awe of the engineering, a little fearful of its capabilities, hesitant about what it could mean for the future of humanity and charmed by its design and styling. The periwinkle blue iteration of Atlas that I met on the show floor at CES 2026 almost bears more resemblance to a Dyson product than it does the industrial robots that defined Boston Dynamics’ early days, when it was best known for its work with DARPA.

«There’s a lot of really specific things about this robot that probably look a little weird,» said Zachary Jackowski, Boston Dynamics VP and general manager of Atlas. He pointed to the legs, which he described as «like nothing anyone else was doing.»

Atlas’ thighs are narrow set and in line with the torso, while the calves are wider set, attached to their upper counterparts with a circular joint. This robot is, in fact, all subtle curves and soft lines. There are no harsh edges or stark angles.

During a year when CES has been flooded with humanoid robots, Atlas definitely does stand out due to its design. It appears both less classically human and less industrial than some of its peers, while also lacking the often intimidating, featureless faces they tend to exhibit. Instead, it has two low-set cameras resembling eyes placed where you’d usually expect a mouth to be. Its face is a perfect flat circle, defined by an LED halo that gives it a somewhat Pixar lamp effect.

I asked Jackowski why Boston Dynamics decided to skew so relatively unhuman with this version of its humanoid. «Well, it’s not a human,» he said. «It projects the wrong first impression about a robot to have it pretend to be something that it’s not.»

Particularly in the early days of humanoids, he added, robots won’t have anything like human-like intelligence. People should look at it and see it for what it is — a tool for performing tasks safely and efficiently.

In fact, most of the design decisions were made to keep Atlas as simple, scalable and safe as possible, Jackowski said. I remark that there’s some irony in thinking of a humanoid robot as simple, given the complexity of the technology and development process to bring Atlas to life.

The key to making it simple, Jackowski said, is having a strong enough grasp of the technology to «accomplish the complex thing of building a humanoid robot,» but then being able to take it apart and understand that you can use fewer computers and actuators in it while achieving the same results.

And it’s essential to Boston Dynamics that Atlas is perceived as simple. After all, it’s a general-purpose humanoid, which might eventually be sent far and wide to fulfil all manner of roles. Jackowski calls it the «ultimate generalist.»

Simplicity aside, there are aspects of Atlas that Jackowski believes set it apart from other humanoids at the show. «The repairability of this robot is crazy good,» he said. «The runtime is crazy good. The strength is unlike anything.»

From working in Hyundai’s manufacturing plants, Atlas’s job trajectory is to eventually graduate to many of the same industrial environments where Boston Dynamics’ Spot robot works, before moving to bussing tables in the service industry and eventually into the home. The robot will evolve between now and then, Jackowski said. However, this could be an early glimpse of the type of humanoid that will eventually be our housemate.

That’s some way away, though, which is probably for the best. As I gaze up at Atlas, which I’d guess is around the same height as my husband, my feeling is that, however impressive Atlas is, I’m still not ready for it to move in.

This Star Wars Dartboard Has a Secret That Will Stop You From Using the Force to Win

This cool dartboard has cameras to track your score and keep you honest

Right in the middle of the high-tech show floor at CES 2026 sits a pub called the Bull and Barrel with some of the coolest dartboards I’ve seen. Target Darts was showcasing its collaboration with both Star Wars and Xbox. Darts may not be for everyone, but I love «shooting some arrows» in my basement with the family. I also love anything Star Wars themed, so these tick a lot of boxes.

The basic Star Wars set comes with a branded board and wall protector that resembles the cockpit of the Millennium Falcon and costs $200. The board is of very high quality, with a tight-knit sisal fiber face, and the protector is thick enough to keep stray shots out of your drywall. The graphics are cool too, with nods to the original Falcon and even have the gold dice hanging above.

The big tech twist to this board, though, is the Omni light ring around the outside. It uses four cameras to track your dart’s position, then sends that info to an app that keeps score. The scoreboard is crisp and clear and uses the voice of legendary darts announcer John McDonald to narrate your game. It’s pretty great to hear his voice announce my terrible scores.

The Omni also allows you to connect with other players worldwide via shared scoreboards. I love the idea of my dad having a board at his house or playing a match with me at my house. It adds a feeling of community to home darts that you don’t normally get outside a pub or bar.

The Omni is a much more expensive proposition than the Star Wars set, coming in at $650, but if you’re serious about the game and a Star Wars fan, it looks to be a great investment.
