Finding ways to integrate electronics into living tissue could be crucial for everything from brain implants to new medical technologies. A new approach has shown that it’s possible to 3D print circuits into living worms.

There has been growing interest in finding ways to more closely integrate technology with the human body, in particular when it comes to interfacing electronics with the nervous system. This will be crucial for future brain-machine interfaces and could also be used to treat a host of neurological conditions.

But for the most part, it’s proven difficult to make these kinds of connections in ways that are non-invasive, long-lasting, and effective. The rigid nature of standard electronics means they don’t mix well with the squishy world of biology, and getting them inside the body in the first place can require risky surgical procedures.

A camel cannot go through the eye of a needle. But researchers at ETH Zurich have now achieved something that—figuratively speaking—comes quite close. They have developed a new approach to minimally invasive surgical instruments, allowing large objects to be brought into the body through a narrow catheter. Their demonstration study has been published in the journal Nature Communications.

This works as follows: The researchers disassemble such devices into individual parts and then slide them through the catheter in a row, like a string of pearls. At the end of the , the parts assemble themselves into a predefined shape thanks to built-in magnets.

In its research, the team—led by ETH doctoral student Hongri Gu, who is now a at the University of Konstanz—was primarily concerned with demonstrating the many possibilities of this new approach. In a relatively simple way and using 3D printing, the scientists also constructed an endoscopic grasper. Moreover, they showed that the new approach makes it possible to assemble an endoscope head consisting of three parts.

The space agency teamed up with university researchers to investigate the best methods for 3D printing space batteries.

A team of researchers at the University of Texas at El Paso (UTEP) and Youngstown State University (YSU) are collaborating to develop 3D-printed batteries for future lunar astronauts.

Relativity Space, a 3D-printing specialist, launched the inaugural flight of its Terran 1 rocket late on Wednesday night, which successfully met some mission objectives before failing to reach orbit.

Terran 1 lifted off from LC-16, a launchpad at the U.S. Space Force’s facility in Cape Canaveral, Florida, and flew for about three minutes. While the rocket cleared a key objective — passing the point of maximum atmospheric pressure during an orbital launch, known as Max Q — its engine sputtered and shut down early, shortly after the second stage separated from the first stage, which is the larger, lower portion of the rocket known as the booster.

Relativity launch director Clay Walker confirmed that there was an “anomaly” with the upper stage. The company said it will give “updates over the coming days” after analyzing flight data.

“The goal is for community groups or individual citizens anywhere to be able to measure local air pollution.”

As per an estimation by WHO, air pollution causes around 4 million annual premature deaths all over the globe. Considering this issue, an MIT research team launched an open-source version of an economical, mobile pollution detector through which individuals can track the air-quality more broadly.

The detector, named Flatburn, can be fabricated through 3D printing or by ordering cheap parts. The researchers have now conducted tests and calibrated the detector concerning existing ultra-modern machines and are making people aware of how to assemble, use, and interpret the data.


Flatburn is an open-source, mobile pollution detector from the MIT Senseable City Lab intended to let people measure air quality cheaply.

Up until now, it was still infamously difficult to include sensors in 3D designs.

Engineers might be able to create smart hinges that can detect when a door has been opened or gears inside motors that can communicate their rotational speed to a mechanic by integrating sensors into rotational systems.

Even while improvements in 3D printing allow for the quick manufacture of rotational devices, it is still infamously difficult to include sensors in the designs.

A team of engineers at the University of New South Wales in Sydney, Australia, has developed a tiny, flexible robotic arm that’s designed to 3D print material directly on the surface of organs inside a living person’s body.

The futuristic device acts just like an endoscope and can snake its way into a specific location inside the patient’s body to deliver layers of special biomaterial to reconstruct tissue, clean up wounds, and even make precise incisions — an amazing jack-of-all-trades they say could revolutionize certain types of surgery.
