Researchers at the Massachusetts Institute of Technology have created a double-armed, laser-guided robot that can basically 3D print a 50-foot-wide house in less than 14 hours with almost no human intervention. The Digital Construction Platform, described today in Science Robotics, consists of a large hydraulic arm mounted on a platform with motorized treads, plus a smaller electric-powered arm for finer movements. The MIT team programmed the solar-powered machine to spray out foam construction material, layer by layer, to form a 12-foot-high, igloo-like structure big enough to house a family. The researchers hope such robots could someday be sent to the moon, Mars or Antarctica to build “print-in-place” habitats from the materials at hand … or at manipulator.

Off-grid housing that actually works for families is hard to come by, but that’s what ReGen Villages is striving towards with their concept for new self-sustaining communities.

The startup real estate company has a dream to create regenerative communities that not only produce their own food but also generate their own power, meaning what’s usually only possible for rural areas with renewable energy sources would be a reality for people that want these luxuries while having close neighbors.

This idea is more than just a dream, however, as the development company has its sights on their first site in Almere, Netherlands with the goal of opening it in 2018.

Boeing, the world’s second-largest defense firm, has detailed the hardware it thinks humanity will need to stage a piloted mission to Mars — and outlined plans for lunar bases, which will serve as a jumping off point for deep space missions, and assist in exploration of the Moon.

Boeing, and five other companies, are already collaborating with NASA to develop the Space Launch System (SLS), which it is hoped will power a trip to Mars. Now, the firm has offered up conceptual designs for other accessories it will be useful for the mission, and a more general vision of how it could be achieved — and made easier on repeat visits. Of particular note are a deep space habitat design, and transport vehicle.

Sometimes people bring up overpopulation scenarios where the population can fit inside Texas. But they ask, what about all the stuff that supports that population? Here is one answer.


Located in an abandoned 70,000-square-foot factory in Newark, New Jersey, the world’s largest vertical farm aims to produce 2,000,000 pounds of food per year. This AeroFarms operation is also set up to use 95% less water than open fields, with yields 75 times higher per square foot. Their stacked, high-efficiency aeroponics system needs no sunlight, soil or pesticides. The farm’s proximity to New York City means lower transportation costs and fresher goods to a local market. It also means new jobs for a former industrial district.

Around the world, urban farms are sprouting up at the intersection of new growing technologies and localvore movements. They vary in scale and focus, but their goals are generally similar: produce fruits and vegetables in more efficient, cheaper and greener ways. Growing in controlled environments also reduces environmental variables, like pests, weather and even seasons (allowing for more predictable year-round yields). Factory farm tenants can also take over and adaptively reuse structures in depressed areas with disused industrial building stock, creating employment opportunities in the process.

In a way, these endeavors are a natural extension of long-standing trends in farming. Small farms gave way to large farms, but the latter still involved open fields and variable environments. Urban farms take things to the next level, making the farm-to-table distance shorter, controlling conditions and further optimizing around available space.

Depression, anxiety, grief, despair, stress—even suicide: The damage of unfolding climate change isn’t only counted in water shortages and wildfires, it’s likely eroding mental health on a mass scale, too, reports the American Psychological Association, the preeminent organization of American mental health professionals.

Direct, acute experience with a changing climate—the trauma of losing a home or a loved one to a flood or hurricane, for example—can bring mental health consequences that are sudden and severe. After Hurricane Katrina, for example, suicide and suicidal ideation among residents of areas affected by the disaster more than doubled according to a paper led by Harvard Medical School, while one in six met the criteria for PTSD, according to a Columbia University-led paper. Elevated PTSD levels have also been found among people who live through wildfires and extreme storms, sometimes lasting several years.

But slower disasters like the “unrelenting day-by-day despair” of a prolonged drought, or more insidious changes like food shortages, rising sea levels, and the gradual loss of natural environments, will “cause some of the most resounding chronic psychological consequences,” the APA writes in its 69-page review of existing scientific literature, co-authored by Climate for Health and EcoAmerica, both environmental organizations. “Gradual, long-term changes in climate can also surface a number of different emotions, including fear, anger, feelings of powerlessness, or exhaustion.”

EVER since ENIAC, the first computer that could be operated by a single person, began flashing its ring counters in 1946, human beings and calculating machines have been on a steady march towards tighter integration. Computers entered homes in the 1980s, then migrated onto laps, into pockets and around wrists. In the laboratory, computation has found its way onto molars and into eyeballs. The logical conclusion of all this is that computers will, one day, enter the brain.

This, at least, is the bet behind a company called Neuralink, just started by Elon Musk, a serial technological entrepreneur. Information about Neuralink is sparse, but trademark filings state that it will make invasive devices for treating or diagnosing neurological ailments. Mr Musk clearly has bigger plans, though. He has often tweeted cryptic messages referring to “neural lace”, a science-fictional concept invented by Iain M. Banks, a novelist, that is, in essence, a machine interface woven into the brain.

A webpage today is often the sum of many different components. A user’s home page on a social-networking site, for instance, might display the latest posts from the users’ friends; the associated images, links, and comments; notifications of pending messages and comments on the user’s own posts; a list of events; a list of topics currently driving online discussions; a list of games, some of which are flagged to indicate that it’s the user’s turn; and of course the all-important ads, which the site depends on for revenues.

With increasing frequency, each of those components is handled by a different program running on a different server in the website’s data center. That reduces processing time, but it exacerbates another problem: the equitable allocation of network bandwidth among programs.

Many websites aggregate all of a page’s components before shipping them to the user. So if just one program has been allocated too little bandwidth on the data center network, the rest of the page—and the user—could be stuck waiting for its component.

In a bid to get around terrestrial height restrictions, Clouds Architecture Office has proposed suspending the world’s tallest skyscraper from an asteroid, leaving residents to parachute to earth.

New York-based Clouds Architecture Office drew up plans for Analemma Tower to “overturn the established skyscraper typology” by building not up from the ground but down from the sky by affixing the foundations to an orbiting asteroid.

“Harnessing the power of planetary design thinking, it taps into the desire for extreme height, seclusion and constant mobility,” said the architects, who have previously drawn up proposals for space transportation and a 3D-printed ice house on Mars.
