For decades now we’ve been teased with hoverboard concepts, either from science fiction or highly limited real-life versions, but now aerospace company Arca is taking orders for what it claims is the real deal. The ArcaBoard appears to be the closest thing to the technology from Back to the Future: Part II that we’ve seen so far.
The dream of melding biological and man-made machinery is now a little more real with the announcement that Columbia Engineering researchers have successfully harnessed a chemical energy-producing biological process to power a solid state CMOS integrated circuit.
According to study lead professor Ken Shepard, this is the world’s first successful effort to isolate a biological process and use it to power an integrated circuit, much like the ones we use in phones and computers.
The researchers developed the system by using an artificially created lipid bilayer membrane containing naturally occurring ion pumps, which are powered by the biological world’s “energy currency molecule,” ATP (adenosine triphosphate). ATP is the coenzyme that transfers chemical energy between living cells. It is an end product of processes such as photosynthesis and cellular respiration, and it powers the mechanical work of living systems such as cell division and muscle contraction.

Hydras, simple fresh-water animals, have the ability to live forever if kept in ideal conditions, a recent study shows.
The organisms are made mostly of stem cells that have the ability to continually divide, thus constantly renewing the body.
“The differentiated cells of the tentacles and the foot are constantly being pushed off the body and replaced with new cells migrating from the body column,” Daniel Martinez, a biologist at Pomona College, said in a statement.
Looks pretty sweet, although maybe make it look more like a surf board.
With Arca Space’s hoverboard prototype the world has finally came closer to inventing a somewhat flying “board” capable of lifting a person above any type of ground and transporting them over “distances.”
This week on the GeekWire radio show and podcast, we’re joined by Alan Boyle, GeekWire’s aerospace and science editor, who catches us up on the biggest news from space this year, literally putting the universe in perspective. We also look ahead to 2016 and bring things closer to Earth with an explanation of the FAA’s new registration requirements for that recreational drone under your tree for the holidays.

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.
Self-driving cars could mean a lot of free time for drivers.
We won’t have to drive soon, so what’re we going to do in cars? Nissan has an answer: http://voc.tv/1P6L9zh
In the third century BCE, King Hiero II of Syracuse asked Archimedes to devise a number of death traps to thwart Roman invaders. Among the many designs the great inventor drew up was a solar death ray. The basic idea was to build an array of mirrors that could reflect rays of light into a central blast, causing Roman ships to burst into flame. It’s unlikely the weapon ever made it past the blueprint stage, but it became an incredibly influential model nonetheless. Archimedes was perhaps the first solar power convert, searching for a way to take advantage of the inconceivable amount of energy our friendly neighborhood star barfs up every second.
The only thing that would make Archimedes’ solar death ray more fascinating is if it was technically feasible, socially benevolent, and in space. That’s where John Mankins comes in. A NASA veteran, aerospace entrepreneur, and space-based solar power (SBSP) expert, Mankins designed the world’s first practical orbital solar plant. It’s called the Solar Power Satellite via Arbitrarily Large PHased Array, or SPS-ALPHA for short. If all goes to plan, it could be launched as early as 2025, which is sooner than it sounds when it comes to space-based solar power timelines.
Scientists have been aware of the edge the “space-down” approach holds over terrestrial panels for decades. An orbiting plant would be unaffected by weather, atmospheric filtering of light, and the sun’s inconvenient habit of setting every evening. SBSP also has the potential to dramatically increase the availability of renewable energy.
