Up until now, everything we’ve ever used in space has been brought there from Earth. Planetary Resources Inc. has long-term ambitions to mine the infinite resources space provides. In the mean-time, they’ve proven its possible by 3D printing material derived from an asteroid.
Imagine if your clothing could, on demand, release just enough heat to keep you warm and cozy, allowing you to dial back on your thermostat settings and stay comfortable in a cooler room. Or, picture a car windshield that stores the sun’s energy and then releases it as a burst of heat to melt away a layer of ice.
According to a team of researchers at MIT, both scenarios may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat, whenever it’s needed. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.
Although the sun is a virtually inexhaustible source of energy, it’s only available about half the time we need it—during daylight. For the sun to become a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding could provide a highly efficient method for storing the sun’s energy through a chemical reaction and releasing it later as heat.
For years, the term “Anthropocene” has been used to informally describe the human era on Earth. But new evidence suggests there’s nothing informal about it. We’re a true force of nature — and there’s good reason to believe we’ve sparked a new and unprecedented geological epoch.
A team of international geoscientists say the time has come for us to formally recognize the Anthropocene as a new epoch, one as significant as previous geological eras like the Holocene and Pleistocene. According to the new study, which appears in the latest issue of Science, it began sometime around the midpoint of the 20th century, and is fueled by a number of unquestionably human influences — including elevated greenhouse gas levels and the global proliferation of invasive species, along with the spread of materials such as aluminium, concrete, fly ash, and even fallout from nuclear testing.
3D printed ceramics are still something of a rarity, compared to other materials. The material has several limitations; it’s generally printed by sintering powder materials that result in porous, relatively weak end products with low heat resistance. This greatly limits the size and shape of objects that can be printed; 3D printed ceramic objects have thus far been pretty much limited to relatively small decorative items or tableware. But that’s all about to change, thanks to a new material developed by research and development company HRL Laboratories, LLC.
HRL, which is owned by Boeing and General Motors, has developed a ceramic resin that can be printed through stereolithography. The company actually calls it a “pre-ceramic” resin that prints like a typical plastic resin, and is then fired in a high temperature kiln, which turns it into a dense ceramic. The resulting objects are about ten times stronger than other 3D printed ceramics, have virtually no porosity, and can withstand temperatures higher than 1700°C.
After the acquisition of Phenix Systems, 3D Systems has been slow to roll out its metal 3D printing technology, an issue raised in a class action lawsuit against the company. Nevertheless, the company has been making progress and, today, 3D Systems announced the availability of their newest system, the ProX DMP 320.

DARPA funds the Atoms-to-Products program that aims to maintain quantum nanoscale properties at the millimeter scale of microchips.
The main goal of the atoms-to-products program is to create technology and processes needed to create nanometer-scale pieces, with dimensions almost the size of atoms, into components and materials only millimeter scale in size. And to spur developments in the program DARPA has now posed the challenge to 10 laboratories across the nation.
To get the full benefits of nanoscale engineering at the millimeter scale, the organization has partnered with Intelligent Materials Solutions. “Our initial project will be to control infrared light by assembling nanoscale particles into finished components that are one million times larger,” explains Adam Gross, the team leader working closely with Christopher Roper to bring the Atoms-to Products project to fruition.
It’s a new resin.
Researchers at Panasonic PCRFY −0.78% in Japan have developed a new kind of resin that has the potential to make personal health electronics leaner and comfier.
The stretchy tech, announced by the company on Dec. 28, can be used as a base for electronic materials. Its physical properties makes electronics easier to apply to skin or clothing—like a Band-Aid or a tattoo, rather than a watch or a strap.
Scientists have developed a way to produce soft, flexible and stretchy electronic circuits and radio antennas by hand, simply by writing on specially designed sheets of material.
This technique could help people draw electronic devices into existence on demand for customized devices, researchers said in a new study describing the method.

If you haven’t heard of the bionic pancreas, it’s likely you soon will. With diabetes on the rise and the demand for insulin therapies becoming a real pain point for the medical establishment, the need for innovative solutions has spiked. Back in April, we reported on the Do-It-Yourself Pancreas system, a closed-loop artificial pancreas scavenged from a Medtronic pump, Dexcom CGM, a Raspberry Pi, and CareLink USB. Now a fully bionic pancreas similar in design to the Do-It-Yourself model is being developed by doctors at Massachusetts General Hospital and Boston University, with the goal of winning FDA approval. If it succeeds, this will likely be the first bionic organ to see widespread adoption.
Let’s examine some of the previous attempts at bionic organs to see if we can catch a glimpse of where things are heading and some of the societal repercussions that lay in wait. The holy grail of bionic organs is without question the human heart. Coronary artery disease being one of the principal causes of the death worldwide, a fully functioning bionic heart could radically change life expectancy and alter the demographic landscape.
The first bionic hearts, designed over 70 years ago, were plagued by problems that often resulted in thromboembolism and hemorrhage, and made this even more of a gamble than donor transplants. Recent technological advances, however — specifically the advent of bio-prosthetic materials that fool the human immune system into believing the bionic heart is an organic part of the body — could indicate a new era of artificial organs is upon us.
Catching sunlight at every angle.
One of the limitations of current solar panel technology is the panels need to be facing in a certain direction to make the most of the Sun’s rays, otherwise the amount of energy they can absorb drops off dramatically. A newly invented material could make the direction of solar panels much less of a concern in the future.
The material has been produced by electrical engineers at the King Abdullah University of Science & Technology (KAUST) in Saudi Arabia and Taiwan’s National Central University. Not only does the glass coating they’ve come up with soak up sunlight from multiple angles more effectively, it’s also able to keep itself clean — the newly treated panels were able to maintain 98.8 percent of their efficiency after six weeks outdoors.
