As heat and humidity soared and New Yorkers slowed their famously fast strides to cope, a small miracle happened in Midtown: A single-family house was assembled in three days.

The tiny 22-square-meter (237-square-foot) prototype, on display on United Nations Plaza, is designed for a family of four. It’s self-sustaining, producing drinkable water from the air, energy from the sun and food from a vertical vegetable garden embedded in the exterior walls. And at an expected price of about $35,000, it may provide an affordable answer to a global housing shortage.

“In this climate, this home would produce enough food for a family of four for about 260 days” out of a year, said Anna Dyson, a professor of architecture and forestry and environmental studies at Yale University. “In better climates — in Africa, for example — it could actually produce a surplus of food.”

An ambitious smart-city project spearheaded by Alphabet subsidiary Sidewalk Labs has run into local resistance, causing delays.

The backstory: Waterfront Toronto, a development agency founded by the Canadian government, partnered with the Google sister company in October 2017 to create a futuristic neighborhood on the Toronto waterfront. Sidewalk Labs plans to fill the 12-acre plot with driverless shuttle buses, garbage-toting robots, and other gadgets to show how emerging technologies can improve city life.

The problem: Sidewalk Labs’ connection to Google and vague descriptions of its business model alarmed privacy advocates and urban planners from the start. Local pushback has increased since, causing a key supporter to resign from the project and delaying the release of its final development plan to spring 2019.

This video takes the viewer on a tour of a 3D image of the supernova 1987 A, created using data collected by the international astronomy facility ALMA. The p urple area indicates emission from SiO molecules and the yellow area indicates emission from CO molecules. The blue ring is NASA/ESA Hubble Space Telescope data that has been artificially expanded into 3D.

The 21st century’s longest lunar eclipse has passed, eclipse doomsday fever has subsided, and all that’s left are the memories and pictures, which you can find everywhere online. But one image really stood out to us—not because of the way the Moon looked, but because of how it made the Earth look.

Australian amateur astronomer Tom Harradine had always wanted to create an image of the Earth’s umbra, the darkest inner region of the shadow. But during an eclipse, the Moon doesn’t pass through the whole of the Earth’s shadow. He needed a trick in order to show the whole thing.

“One way, I thought, to get the full circle of the umbra from a single eclipse event is to artificially locate and rotate successive eclipse images so as the shadow boundary forms a circle,” he said. “The trick is to keep the curvature of the shadow matching up as precisely as possible. Which images to choose is up to artistic license and I chose a spiral effect, not only to show the umbra but to also show the progression of the eclipse as time went on.”

Grow-your-own organs could be available for desperately ill patients within five years, after scientists successfully transplanted bioengineered lungs into pigs for the first time.

The team at the University of Texas Medical Branch (UTMB) showed that lab-grown organs were quickly accepted by the animals, and within just two weeks had developed a network of blood vessels.

Previous attempts have failed with several hours of transplantation because the organs did not establish the complicated web of vessels needed for proper oxygen and blood flow.

Scientists have identified a group of planets outside our solar system where the same chemical conditions that may have led to life on Earth exist.

The researchers, from the University of Cambridge and the Medical Research Council Laboratory of Molecular Biology (MRC LMB), found that the chances for life to develop on the surface of a rocky planet like Earth are connected to the type and strength of light given off by its .

Their study, published in the journal Science Advances, proposes that stars which give off sufficient ultraviolet (UV) light could kick-start life on their orbiting in the same way it likely developed on Earth, where the UV light powers a series of chemical reactions that produce the of life.

“We should not start from steam and railways, or the old technologies—that is already done,” Assefa argues.

That makes sense to academics like Singh — though he also cautions that political forces are often slow to see the bigger picture. There is definitely an opportunity for developing countries, he says. “But any time we have a technological revolution, the political institutions have to catch up.”

A 2017 report (pdf) by the World Wide Web Foundation suggested that Ethiopian “intelligence services are using machine intelligence techniques to break encryption and find patterns in social media posts that can be used to identify dissidents.” And while mobile phone and internet penetration in Ethiopia is comparatively poor—a situation made worst amid widespread anti-government protests, which prompted an internet crackdown in February — the report added that government surveillance and oppression could increase as the use of smartphones expands.
