We have seen 3D printed buildings before but most of them were prototypes, built off-site or not used afterwords, but nothing compares to this house built by Apis Cor.

Apis Cor used a unique house 3D printing machine they developed and made an on-site house in 24 hours for the cost of some 10000 USD. It has surface of 38 square meters (409 square foot) and has been built in Stupino town, Moscow region, Russia.

The finished house is fully livable with all the appliances. Very cool!

Never before have businesses been able to build billion-dollar valuations in so little time. Never before have incumbent enterprises been able to go out of business so quickly. Disruption is now commonplace, and augmented reality (AR) is emerging as yet another avenue to turn industries on their heads. But what direction will this new technology take?

AR overlays digital information on the physical world using a smartphone (think Pokémon Go) or a headset. In its simplest form, AR is simply a rectangular display floating in front of the eyes, à la Google Glass. More advanced forms will drop video game characters or useful information seamlessly onto physical objects, from homes to industrial warehouses.

While virtual reality is moving into a more commercial phase, AR is a little earlier in its development. But AR’s potential practical applications are significant. So, what’s in store for AR in the coming years?

Forget the moon. The next giant leap for mankind could be building a habitat on Mars.

The fourth planet from the sun may be cold — Martian winters can reach -190 degrees Fahrenheit (−87 degrees Celsius) — full of deserts and lacking in oxygen, but for Behrokh Khoshnevis it’s humans’ next destination.

The pioneering professor in engineering at the University of Southern California has been working with NASA on the possibility of building a colony on Mars since 2011.

NASA has enlisted a professor from the University of Central Florida (UCF) in order to find a way of 3D printing structures on Mars.

Pegasus Professor Sudipta Seal, interim chair of UCF’s Materials Science and Engineering program is looking at how metals can be extracted from Martian soil. Speaking about the project, Seal said,

It’s essentially using additive-manufacturing techniques to make constructible blocks. UCF is collaborating with NASA to understand the science behind it.

Real estate is a valuable commodity aboard a CubeSat, a compact satellite about the size of a shoebox, so the smaller each component can be made, the better. To that end, scientists at NASA’s Kennedy Space Center and the University of Miami are developing a thin, solid-state battery, which could not only save space for more important instruments aboard satellites, but also provide power on other planets, in cars or within the walls of a home.

At less than 3 mm (0.1 in) thick, the new batteries could be incorporated into the structure of pint-sized satellites, rather than taking up room in the area designated for research instruments. The batteries are made by sandwiching a solid-state battery layer between two layers of compressed carbon fiber.

“Creating a structural battery material could revolutionize the way NASA operates small payloads,” says senior principal investigator, Luke Roberson. “Rather than placing a battery in the experiment taking up 20 to 35 percent of the available volume, the battery now resides in the payload structure, thereby opening up additional free space for researchers to perform more science.”

We will need a good dose of healthy stoicism if we are to survive in the world after work. Luxury items will be significantly reduced in the world we’re imagining. Stoics like Marcus Aurelius and Seneca recommended that we adjust our desires to simple, reliable pleasures, like fresh water, decent bread, modest clothing, and good friends. Luxury pleasures are rare and unreliable so we suffer more when they fail to materialize.

But chocolate cake is delicious and diamonds are beautiful. When Plato sketched a Spartan lifestyle in the Republic, his friends accused him of designing a city for pigs not humans — and they demanded that he add spices and luxury to the imagined utopia. While I’m sensitive to this worry, I hasten to point out that many Americans are currently, and by their own initiative, downsizing their sense of the good life. The contemporary “tiny house movement” — which builds elegant housing around 1/10th the size of average homes — is already the kind of stoic adjustment that Americans will need to make when we’re all unemployed.

New research details how to use the radiation and gravity of the stars to decelerate a high-velocity interstellar projectile.

In April last year, billionaire Yuri Milner announced the Breakthrough Starshot Initiative. He plans to invest 100 million US dollars in the development of an ultra-light light sail that can be accelerated to 20 percent of the speed of light to reach the Alpha Centauri star system within 20 years. The problem of how to slow down this projectile once it reaches its target remains a challenge. René Heller of the Max Planck Institute for Solar System Research in Göttingen and his colleague Michael Hippke propose to use the radiation and gravity of the Alpha Centauri stars to decelerate the craft. It could then even be rerouted to the red dwarf star Proxima Centauri and its Earth-like planet Proxima b.

In the recent science fiction film Passengers, a huge spaceship flies at half the speed of light on a 120-year-long journey toward the distant planet Homestead II, where its 5000 passengers are to set up a new home. This dream is impossible to realize at the current state of technology. “With today’s technology, even a small probe would have to travel nearly 100,000 years to reach its destination,” René Heller says.
