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.

​Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have identified a new way to make a semiconductor laser that operates at terahertz frequencies. The breakthrough could lead to development of a new class of high-quality, powerful lasers for use in space exploration, military and law enforcement efforts and other applications.

The terahertz range of frequencies occupies the space on the electromagnetic spectrum between microwave and infrared. Terahertz waves can be used to analyze plastics, clothing, semiconductors and works of art without damaging the materials being examined; for chemical sensing and identification; and to investigate the formation of stars and composition of planetary atmospheres.

Researchers led by Benjamin Williams, a UCLA associate professor of electrical engineering, have created the first vertical-external-cavity surface-emitting laser, or VECSEL, that operates in the terahertz range. VECSELs that use visible light have been used extensively to generate high-powered beams, but the technique has not previously been adapted for terahertz frequencies.

Graphene is a super strong, two-dimensional material with atom-thick layers. But now, a team of scientists have developed a new material with a similar structure that they’re calling borophene, and it may have graphene beat.

Borophene, a one atom thick sheet of boron, is being introduced by scientists as the next big thing after graphene, another two-dimensional material that made headlines back in 2004. If you aren’t aware, graphene is basically a supermaterial. A single layer of this is about 100 times stronger than steel and it is extremely flexible.

How does water on the surface of this bizarre material control UV light emission and also its conductivity? (credit: Mohammad A. Islam et al./Nano Letters)

In a remarkable chance landmark discovery, a team of researchers at four universities has discovered a mysterious material that emits ultraviolet light and has insulating, electrical conducting, semiconducting, superconducting, and ferromagnetic properties — all controlled by surface water.

It happened while the researchers were studying a sample of lanthanum aluminate film on a strontinum titanate crystal. The sample mysteriously began to glow, emitting intense levels of ultraviolet light from its interior. After carefully reproducing the experimental conditions, they tracked down the unlikely switch that turns UV light on or off: surface water moisture.

China wants to be the leading force in manned space exploration, and is exploring sending people to the far side of the moon, Mars, asteroids, and further into deep space.

Becoming the second largest economy in the world and an emerging superpower of its own, China wishes to add deep space exploration into its achievement portfolio. Besides the ongoing moon exploration, its scientists are considering going deeper into the solar system, including Mars, asteroids, and even manned deep-space mission. Liu Jizhong, director of the lunar exploration program and space engineering center, pointed out that China has to be more pioneering, tackling problems such as high speed deep space exploration, energy and power generation, space robot development, and more. He also said that China must cooperate with others as space exploration is an undertaking shared by the entire human species.

China currently intends to explore the far side of the moon, something that has never been done before. It would require a relay satellite for communication and navigation on Lagrange point, where the satellite could orbit within the combined gravitational pull of the Earth-moon system, as said by Zhang Lihua of China Spacesat Co. While China believes that robots are critical to the mission, it also believes that these trips must be manned in order to effectively leverage human decision-making. China also says they are designing footed robots to explore asteroids and better understand their material composition.

Throughout many remote villages in Ethiopia, water gathering is quite an ardous and dangerous task. With the burden typically falling on matriarchs of the family, the trip to the nearest water source can take hours if not all day. More often than not, that water fetched on these long journeys is commonly contaminated with dangerous elements such as human and animal waste. Additionally, many women have little choice but to bring their young children along, which not only puts them in harm’s way, but also keeps them out of school.

The WarkaWater Towers were inspired by the local Warka tree, a large fig tree native to Ethiopia that is commonly used as a community gathering space. The large 30 foot, 88 pound structures are made out of juncus stalks or bamboo woven together to form the tower’s vase-like frame. Inside, a plastic mesh material made of nylon and polypropylene fibers act as micro tunnels for daily condensation. As droplets form, they flow along the mesh pattern into the basin at the base of the towers. By harvesting atmospheric water vapor in this way, it’s estimated that at least 25 gallons of potable water can be sustainably and hygienically collected by the towers every day.
