Earthquake Resistant Concrete

University of British Columbia (UBC) researchers have developed an eco-friendly concrete that can be sprayed onto the exterior of buildings to make them as strong as steel and capable of withstanding many unforeseen disasters. Called Eco-friendly Ductile Cementitious Composite (EDCC), it's mainly comprised of an industrial by-product called fly ash, which makes it durable, malleable and much more ductile than normal concrete. The research team sprayed EDCC on concrete block walls one-half inch thick, and then simulated a magnitude 9 earthquake. "The results of these tests have been amazing. We can shake the wall extensively without it failing," said UBC engineering Ph.D. candidate Salman Soleimani-Dashtaki. Click here to view the first image in today's viral picture gallery.

Treepex

Treepex is not a concept, but rather a real device that claims to use living tree cells compressed in replaceable cartridges to transform carbon dioxide into oxygen, emulating a tree's ability to filter polluted air into mineral-enriched air. It was developed by a Georgian, Tbilisi-based, startup using a new technology called CRISPR, which is allegedly able "to extract the DNA of actual trees to recreate the living cells that are responsible for photosynthesis" by simply inserting a cartridge into the tubular Treepex.

Moon Base Alpha

SpaceX founder Elon Musk announced today that his company's plans now include living on not just Mars, but also the moon. The next-generation BFR rocket will make it possible to establish a moon base, and has unveiled the first concept image of the future rocket landing on the rocky surface to drop off supplies.

Two Asteroids Orbiting

Astronomers have observed an object in space unlike anything they've seen before: 288P, a binary asteroid - or two asteroids orbiting one other. Just like a comet, it boasts a long tail and bright coma, or cloud of dust and gas surrounding a comet's nucleus. It's officially the first binary asteroid they have ever observed that can also be classified as a comet. Continue reading for another video and more information.

Invisibility Cloak Rochester Cloak

A team of researchers, lead by physicist John Howell, have created a real-life invisibility cloak. Called the Rochester Cloak, it's made from a combination of optical lenses, and basically, any object that passes behind a certain line of sight can be made to disappear from view. More specifically, a simplified four-lens system is used to bend light around any objects you put into the middle of the chain, or in other words, you're able to see the area in the background as normal, but not the item in the foreground.

Water-Powered Trike

Scientist Francois Gissy now has a project that tops his Ferrari-beating jet-powered bicycle with a 207-mph top speed, and it's a water-powered trike that does 0-62 mph in just 0.55 seconds, while topping out at 162-mph top speed in just the 1/8th mile. This homemade creation was made from a motorcycle front fork, go-kart rear wheels, and a carbon-fiber-wrapped aluminum tank that holds 35 gallons of rainwater at 6000 psi of pressure.

Solar Eclipse 4K



Video credit: Peta Pixel

Photographer JunHo managed to capture the Great American Eclipse up-close, and in 4K quality, using a 2160mm f/12 telescope, Panasonic GX85, and a RST-150H robotic mount by RainbowAstro to trace the edge of totality. "RST-150H weighs only 3.5kg (7.7 lbs) but carries up to 15kg (33 lbs) of optical equipment without any counter weight. RST-150H mount is specially programmed to trace Sun's peripheral during total eclipse period to match C2 and C3 contact moments. This allows us to catch breath stopping moments of Sun set and rise over the Moon's horizon," said JunHo. Continue reading for two more videos and information.

North Korea Hydrogen Bomb


North Korea conducted its most powerful nuclear test to date earlier today, and it's claimed to be an advanced hydrogen bomb for a long-range missile. This prompted the threat of a "massive" military response from the United States if it or its allies were threatened. As opposed to the relatively simple atomic bomb, the hydrogen bomb can be 1,000 times more powerful, because it uses fusion - or atomic nuclei coming together - to produce explosive energy, rather than fission.

SkinGun Stem Cells


You've probably seen, or at least heard of, RenovaCare's SkinGun over the past few years, but now, it's finally available to medical professionals worldwide - still awaiting approval in US. Simply put, it sprays a patient's own self-donated (autologous) stem cells to treat burns and other wounds. It's used in conjunction with a technique that isolates adult stem cells from a postage stamp-sized sample of the patient's own skin for application to the wound site, where they differentiate into normal skin. This treatment can replace conventional methods of treating severe wounds, such as skin grafting. Studies demonstrate that damaged skin tissue regenerates after skin gun treatment significantly more quickly than after traditional treatment methods.

Glass Building Blocks

Forget solar panels, researchers from Exeter University have invented glass building blocks embedded with small solar cells. This means they not only generate their own energy, but also provide thermal insulation, while allowing natural light to enter buildings. Called "Solar Squared," the solar cells are embedded during the manufacturing process with an array of optical elements. Continue reading for another picture and more information.
