Summer. Blue sky. Sunshine. But you don’t notice much of it in the office or in your home, because the blinds block the view so that the heat stays outside. This scenario could soon be a thing of the past: EPFL researchers are working with Empa on a window glass that keeps out the heat in summer and at the same time allows a clear view of the outside world.

Depending on the season, windows must have a different function in order to provide sufficient comfort in offices and apartments. In summer they should keep heat away and prevent glare from the sun. In winter they should distribute the little light optimally in the room. A team led by Andreas Schüler from the Laboratory for Solar Energy and Building Physics at EPFL has recently developed a window that meets all these criteria. In cooperation with Empa researchers led by Patrik Hoffmann from the Laboratory for Advanced Materials Processing in Thun, work is currently underway on their manufacture—which could soon make sun blinds redundant. Seasonal window glass reduces summer overheating and glare in buildings and ensures high solar energy and daylight input in winter. All this without impairing the view outwards through dimming or blinds.

Jing Gong, a Ph.D. student at EPFL, used Empa’s highly complex laser system in Thun to produce a so-called master form with a microstructured surface with the precision laser. Micro mirrors are then evaporated into these micro-grooves and encapsulated in a polymer film. This film can then be easily inserted into a conventional double-glazed window. The arrangement of so-called “Compound Parabolic Concentrator” (CPC) lenses is used to optimally reflect sunlight with low restrictions in visibility. While the first prototypes have been developed in the laboratory, the researchers are already working on up-scaling. In a pilot project in cooperation with BASF Switzerland, the team is working on a manufacturing process that should make it possible to produce the window glass coating consisting of millions of micro mirrors with high precision, quickly and cost-effectively. This poses a major challenge due to the very high optical quality requirements.

America’s water is under threat from many sides. It faces pollution problems, outdated infrastructure, rising costs, and unprecedented droughts and rainfall patterns as the climate changes. Yet at a recent event hosted by the Columbia Water Center, the tone was cautiously optimistic, and the conversation centered on solutions.

“If we have aging infrastructure that’s falling apart, and we’re dealing with climate variability and change, isn’t that a good opportunity to actually do something?” suggested Upmanu Lall, director of the Columbia Water Center.

For decades, the U.S. has been a leader in water management. Now we’re falling behind; in the latest infrastructure report card, dams, drinking water and wastewater all received D ratings. But Lall thinks the country could get an A. Here are some of the solutions, presented at the event, that could help to get us there.

A Purdue University-affiliated startup that seeks to redefine “farm-to-table” when it comes to garden vegetables by delivering its first orders of an appliance that fits under a kitchen counter and grows produce year-round.

Heliponix LLC, founded by two Purdue University graduates, has begun taking orders on its GroPod, a dishwasher-sized device its creators believe will disrupt the landscape of how food is produced in the face of looming worldwide food shortages and increasing concerns about chemical runoff polluting water sources, rampant food waste and water supplies diminishing on a global scale.

“It’s great for consumers and for the environment,” said Scott Massey, CEO of Heliponix.

Viewing the body as a chemical system and treating maladies with pharmaceuticals is so 20th century. In 21st century medicine, doctors may consider the body as an electrical system instead, and prescribe therapies that alter the electrical pulses that run through the nerves.

The defense agency announces funding for 7 projects under its new ElectRx program.

Astronomers have speculated for decades that the giant waves that meander through the Earth’s atmosphere and oceans, driving the weather, might also exist on the Sun. Now those waves have been unambiguously detected inside the Sun, and found to be very similar to those on Earth.

These Rossby waves, or planetary waves, naturally occur in rotating fluids. It is the rotation of the Earth that causes Rossby waves to propagate through the atmosphere and ocean, affecting the climate and weather.

The Sun rotates, too — so, theoretically at least, a similar phenomenon should be taking place in the gases and plasma that make up its layers. Indeed, it should be taking place in all rotating fluid systems.

Space entrepreneur Robert Bigelow’s interest in exotic subjects was as obvious as his company logo. He’d spent years — and millions of dollars — on his own scientific study of UFOs and related topics. For the DIA contract, he created BAASS, a seperate entity housed within his aerospace plant. He hired a team of 46 scientists and investigators, along with dozens of other support personnel.

LAS VEGAS — UFO investigators are hoping to obtain a treasure trove of Pentagon documents that were generated by a once-secret military study of flying saucers and other weird aircraft.

The government confirms there was a UFO program. It supposedly ended in 2012, but the Pentagon has not yet released any reports or files.

A high-energy survey of the early Universe, an infrared observatory to study the formation of stars, planets and galaxies, and a Venus orbiter are to be considered for ESA’s fifth medium class mission in its Cosmic Vision science programme, with a planned launch date in 2032.

The three candidates, the Transient High Energy Sky and Early Universe Surveyor (Theseus), the SPace Infrared telescope for Cosmology and Astrophysics (Spica), and the EnVision mission to Venus were selected from 25 proposals put forward by the scientific community.

Theseus, Spica and EnVision will be studied in parallel and a final decision is expected in 2021.

The facility, which was originally used by the US military to spy on Soviet satellites during the Cold War, is undergoing a major overhaul to attract tourists and researchers alike. In search of inspiration, Snøhetta’s designers took astronomy classes and were captivated by the architecture of the galaxy.

“We learned about the eight shaped analemma diagram that the moon and the sun makes if you watch them from the same point over 365 days,” says Skaare. “We were especially inspired by the ‘ugly moons’ of Mars, with its funny shape,” she says referring Phobos and Deimos, the red-planet’s two lumpy satellites.

Mars’s lumpy-potato moons, in fact, inspired the shape of Solobservatoriet’s visitor cabins. Surrounding the planetarium are several imperfect-sphere rooms for stargazers who want to spend the an evening in the forest—perhaps to catch the spectacular Northern Lights. Designed to accommodate groups of two to 32, the cabins will be loosely scattered around the planetarium, by design.
