Scientists have successfully grown liver tissue capable of functioning for 30 days in the lab as part of NASA’s Vascular Tissue Challenge.

In 2016, NASA put forth this competition to find teams that could “create thick, vascularized human organ tissue in an in-vitro environment to advance research and benefit medicine on long-duration missions and on Earth,” according to an agency challenge description. Today (June 9), the agency announced not one, but two winners of the challenge.

Article I just wrote about how going to Mars is actually good for protecting life on Earth, too.

People often lump going to Mars or the Moon into a this/that fight when it comes to bettering the life of the Earth and its inhabitants. But, it’s not that simple.

The technology we master in the pursuit of space colonization (starti n g at the Moon and Mars / space stations) will serve to advance that on Earth. The things we learn will help provide a guide for what to do on this future planet, and not just life beyond it. Sure, in-situ resource utilization/production will generate rocket fuel on extraterrestrial bodies. But, things like the NASA Kilopower nuclear reactor can lay the groundwork for alternative energies deployed on Earth at scale. I imagine thorium reactors will follow suit while we still try to deploy fusion at a consumer scale and not just a research basis.

3D printed food is no longer the domain of sci-fi fantasy. It’s here and it’s real: but is it really a big deal, or is it just a passing fad?

In science fiction television shows and movies such as those in the Star Trek universe, the food synthesizers or replicators were electronic devices that took base elements and transformed them into any type of food that was desired. This seemingly miraculous device could only exist in the world of science fiction — at least for now. However, thanks to the advances in 3D printing, it is now possible to create food that mimics the taste, shape, and color of familiar dishes.

Over the past few years, 3D printers have become more commonplace in commercial industries and are used to create all types of items that range from small models and jewelry up to large construction items used to create buildings. But what about 3D printed foods? Is it the future of gastronomy, or just a quirky fad?

3D printing, also called additive manufacturing, has become widespread in recent years. By building successive layers of raw material such as metals, plastics, and ceramics, it has the key advantage of being able to produce very complex shapes or geometries that would be nearly impossible to construct through more traditional methods such as carving, grinding, or molding.

The technology offers huge potential in the health care sector. For example, doctors can use it to make products to match a patient’s anatomy: a radiologist could create an exact replica of a patient’s spine to help plan surgery; a dentist could scan a patient’s broken tooth to make a perfectly fitting crown reproduction. But what if we took a step further and apply 3D printing techniques to neuroscience?

Stems cells are essentially the body’s raw materials; they are pluripotent elements from which all other cells with specialized functions are generated. The development of methods to isolate and generate human stem cells, has excited many with the promise of improved human cell function understanding, ultimately utilizing them for regeneration in disease and trauma. However, the traditional two-dimensional growth of derived neurones–using flat petri dishes–presents itself as a major confounding factor as it does not adequately mimic in vivo three-dimensional interactions, nor the myriad developmental cues present in real living organisms.

University at Buffalo (UB) researchers have developed a novel 3D printed water-purifying graphene aerogel that could be scaled for use at large wastewater treatment plants.

Composed of a styrofoam-like aerogel, latticed graphene and two bio-inspired polymers, the novel material is capable of removing dyes, metals and organic solvents from drinking water with 100% efficiency. Unlike similar nanosheets, the scientists’ design is reusable, doesn’t leave residue and can be 3D printed into larger sizes, thus they now aim to commercialize it for industrial-scale deployment.

“The goal is to safely remove contaminants from water without releasing any problematic chemical residue,” explained study co-author and assistant professor of environmental engineering at UB, Nirupam Aich. “The aerogels we’ve created hold their structure when put into water treatment systems, and they can be applied in diverse water treatment applications.”

Watch this studio 3D print a castle. 🤯 👍

Turns out bones and 3D printing have a lot in common 🤔.

Learn how a young team of additive manufacturing engineers helped bring 3D printed parts to the design of the GE9X, the world’s largest jet engine.

Stefka Petkova enjoys building things. It’s a passion she’s had since she was a small child when her dad, an electrician who liked to work on cars, kept the door to his workshop open. “I was exposed to that as a very young child and just got a lot of encouragement,” says Petkova, who she spent many afternoons watching him weld and wire automobiles.
