President Obama Signs Bill Recognizing Asteroid Resource Property Rights into Law

Posted by in categories: Peter Diamandis, space

Redmond, Wash. – November 25, 2015 – Planetary Resources, the asteroid mining company, applauds President Obama who signed the U.S. Commercial Space Launch Competitiveness Act (H.R. 2262) into law. This law recognizes the right of U.S. citizens to own asteroid resources they obtain and encourages the commercial exploration and utilization of resources from asteroids.

“This is the single greatest recognition of property rights in history,” said Eric Anderson, Co-Founder and Co-Chairman, Planetary Resources, Inc. “This legislation establishes the same supportive framework that created the great economies of history, and will encourage the sustained development of space.”

Peter H. Diamandis, M.D., Co-Founder and Co-Chairman, Planetary Resources, Inc., said, “A hundred years from now, humanity will look at this period in time as the point in which we were able to establish a permanent foothold in space. In history, there has never been a more rapid rate progress than right now.”

Toshiba Machine Announces a Metal 3D Printer Ten Times Faster Than Others on the Market

Posted by in categories: 3D printing, innovation

It’s rare to see technology sectors advance as quickly as metal 3D printing has. Until very recently, the technology was lagging a bit behind other forms of 3D printing. Its cost, plus the size of the printers required, limited it mostly to large industrial companies, but just in the last few months there’s been a burst of innovations making metal printers smaller, cheaper and more accessible. From startups like Desktop Metal to major corporations like Additive Industries, this year’s major focus seems to be on advancing metal 3D printing.

The latest company to announce a new metal printer is Toshiba Corporation, which has, in conjunction with its machine tools unit Toshiba Machine, developed a prototype for a metal printer that promises to be ten times faster than most powder bed fusion sintering printers.

Mining the Solar System –Will it Spawn the Next Google?

Posted by in categories: materials, space

Asteroids are primordial material left over from the formation of the Solar System. They are scattered throughout it: some pass close to the Sun, and others are found out beyond the orbit of Neptune. A vast majority have been collected by Jupiter’s gravity into a belt between it and Mars – an area known as the Main Belt. As it turns out, we have been discovering thousands of asteroids that do not belong to the Main Belt, but instead pass near Earth’s orbit – nearly 9,000 to date, with almost a thousand more are discovered every year.

New technology makes metal wires on solar cells nearly invisible to light

Posted by in categories: solar power, sustainability

A solar cell is basically a semiconductor, which converts sunlight into electricity, sandwiched between metal contacts that carry the electrical current.

But this widely used design has a flaw: The shiny metal on top of the cell actually reflects sunlight away from the semiconductor where electricity is produced, reducing the cell’s efficiency.

Now, Stanford University scientists have discovered how to hide the reflective upper contact and funnel light directly to the semiconductor below. Their findings, published in the journal ACS Nano, could lead to a new paradigm in the design and fabrication of .

Inkjet hologram printing now possible

Posted by in categories: chemistry, materials, security

Vivid holographic images and text can now be produced by means of an ordinary inkjet printer. This new method, developed by a team of scientists from ITMO University in Saint Petersburg, is expected to significantly reduce the cost and time needed to create the so-called rainbow holograms, commonly used for security purposes — to protect valuable items, such as credit cards and paper currency, from piracy and falsification. The results of the study were published 17 November in the scientific journal Advanced Functional Materials.

The team, led by Alexander Vinogradov, senior research associate at the International Laboratory of Solution Chemistry of Advanced Materials and Technologies (SCAMT) in ITMO University, developed colorless ink made of nanocrystalline titania, which can be loaded into an inkjet printer and then deposited on special microembossed paper, resulting in unique patterned images. The ink makes it possible to print custom holographic images on transparent film in a matter of minutes, instead of days as with the use of conventional methods.

Rainbow holograms are widely used to fight against the forgery of credit cards, money, documents and certain manufactured products that call for a high level of protection. Even though the technology of obtaining holographic images was already developed in the 1960s, there still exist numerous technical difficulties that impede its further spread and integration into polygraphic industry.

‘Material universe’ yields surprising new particle

Posted by in categories: computing, materials, particle physics, quantum physics

An international team of researchers has predicted the existence of a new type of particle called the type-II Weyl fermion in metallic materials. When subjected to a magnetic field, the materials containing the particle act as insulators for current applied in some directions and as conductors for current applied in other directions. This behavior suggests a range of potential applications, from low-energy devices to efficient transistors.

The researchers theorize that the particle exists in a material known as tungsten ditelluride (WTe2), which the researchers liken to a “material universe” because it contains several , some of which exist under normal conditions in our universe and others that may exist only in these specialized types of crystals. The research appeared in the journal Nature this week.

The new particle is a cousin of the Weyl fermion, one of the particles in standard theory. However, the type-II particle exhibits very different responses to electromagnetic fields, being a near perfect conductor in some directions of the field and an insulator in others.

Russia and Europe Want a Moon Colony—Why Is NASA So Focused on Mars?

Posted by in category: space travel

Only 12 people—all Americans—have put their boots on the Moon. Today, however, NASA has no plans to send humans back to our pockmarked satellite. Instead, its space pioneers will shoot straight to Mars (and wave to the Moon as they pass it by).

Company Plans To Resurrect Humans With Artificial Intelligence By 2045

Posted by in categories: computing, nanotechnology, robotics/AI

A company has announced its intention to resurrect the dead by storing their memories and using artificial intelligence to return them to life. In the future, of course.

Yeaaaaaah. What?

The company is called Humai, and at the moment, it is pretty sparse on details – and we’re still not sure it’s not a marketing ploy or a hoax. At any rate, the company says they want to store the “conversational styles, behavioral patterns, thought processes and information about how your body functions from the inside-out” on a silicon chip using AI and nanotechnology, according to their website.

Q&A With A Space Artist — By Sarah Keartes | Popular Science

“Instead of buying photos of our solar system, artist Michael Benson decided to create his own—and to do it better. The longtime space aficionado learned to piece together mosaics by combining hundreds of NASA images into one planetary landscape. Spacecraft typically record in various color filters to see different elements of the same view. By overlaying them, Benson creates a detailed, true-color picture of the cosmos.”
