As we explore opportunities in space to colonized or even expand business opportunities in space such as mining, and discovering materials that could be brought back to earth to use; it will be important for scientists and researchers to look at ways in how technologies like CRISPR, nanobots, synthetic implants, etc. can assist in mitigating the impacts on humans in space.
A new report commissioned by NASA highlights many of the risks connected with one of the agency’s major goals: putting more humans in space for longer periods of time.
Today, a group of scientists — John A. Rogers, Eric Seabron, Scott MacLaren and Xu Xie from the University of Illinois at Urbana-Champaign; Slava V. Rotkin from Lehigh University; and, William L. Wilson from Harvard University — are reporting on the discovery of an important method for measuring the properties of nanotube materials using a microwave probe. Their findings have been published in ACS Nano in an article called: “Scanning Probe Microwave Reflectivity of Aligned Single-Walled Carbon Nanotubes: Imaging of Electronic Structure and Quantum Behavior at the Nanoscale.”
The researchers studied single-walled carbon nanotubes. These are 1-dimensional, wire-like nanomaterials that have electronic properties that make them excellent candidates for next generation electronics technologies. In fact, the first prototype of a nanotube computer has already been built by researchers at Stanford University. The IBM T.J. Watson Research Center is currently developing nanotube transistors for commercial use.
DNA is similar to a hard drive or storage device, in that contains the memory of each cell of every living, and has the instructions on how to make that cell. DNA is four molecules combined in any order to make a chain of one larger molecule. And if you can read that chain of four molecules, then you have a sequence of characters, like a digital code. Over the years the price of sequencing a human genome has dropped significantly, much to the delight of scientists. And since DNA is a sequence of four letters, and if we can manipulate DNA, we could insert a message and use DNA as the storage device.
At this point in time, we are at the height of the information age. And computers have had an enormous impact on all of our lives. Any information is able to be represented as a collection of bits. And with Moore’s law, which states that computing power doubles every 18 months, our ability to manipulate and store these bits has continued to grow and grow. Moore’s law has been driven by scientists being able to make transistors and integrated circuits continuously smaller and smaller, but there eventually comes a point we reach in which these transistors and integrated circuits cannot be made any smaller than they already are, since some are already at the size of a single atom. This inevitably leads us into the quantum world. Quantum mechanics has rules which are, in many ways, hard for us to truly comprehend, yet are nevertheless tested. Quantum computing looks to make use of these strange rules of quantum physics, and process information in a totally different way. Quantum computing looks to replace the classical bits which are either a 0 or a 1, with quantum bits, or qubits, which can be both a 0 and a 1 at the same time. This ability to be two different things at the same time is referred to as a superposition. 200 qubits hold more bits of information than there are particles in the universe. A useful quantum computer will require thousands or even millions of physical qubits. Anything such as an atom can serve as a quantum bit for making a quantum computer, then you can use a superconducting circuit to build two artificial atoms. So at this point in time we have a few working quantum transistors, but scientists are working on developing the quantum integrated circuit. Quantum error correction is the biggest problem encountered in development of the quantum computer. Quantum computer science is a field that right now is in its very early stages, since scientists have yet been able to develop any quantum hardware.
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.
