Remote Control Drone Buoy

Here’s a nifty lifesaving idea from Noras Performance out of Portugal. U-Safe is a lifesaving buoy that can drive itself around in the water by remote control, meaning it can reach a victim quickly, and transport them to safety if need be.

The U-shaped U-safe is a battery powered device you can use in place of any lifesaving “donut.” When it’s thrown in the water, it propels itself using a pair of electric turbines that take in water and fire it out the back. read more

Boeing has lifted the lid ever so slightly on its entry in the US Navy’s MQ-25 Stingray unmanned tanker competition. The company released a partial image of the swept-wing drone that is currently completing engine runs before starting deck-handling demonstrations next year. read more

Flying Segway?

The Zapata Ezfly looks for all intents and purposes like a Segway of the sky. You stand on a small platform equipped with a series of jet thrusters, holding two handgrips that come up from the base, then rise up into the air and zoom around, steering with your bodyweight. read more

Vietnamese Stilt House

Vietnamese architect Chu Van Dong has completed a tiny house project that offers a cheap and easy solution for temporary housing or tiny living. Dubbed Forest House, the 12-sq m (129-sq ft) home rests on two stilts and is one of three wooden cabins planned for a vast forest landscape in the Sóc Sơn District, 30.6 km (19 mi) outside of Hanoi, Vietnam.

In designing the home Van Dong wanted to create a basic building model, with an accessible and low cost construction method. “It is hoped that the project will inspire temporary housing projects by its simple construction and low cost,” says Van Dong, who is also a designer at Handyman decor and furniture.

The cabin features a large floor-to-ceiling glass wall at the front ofthe home, capitalizing on its...
 “Designed as a small wooden box lying on the sloping hill, each house has a solid structure,” says Handyman. “The interior is arranged reasonably, compact and full of facilities, including glass windows throughout the home, which look straight out over the woods. It’s extremely poetic.”

Growing Potatoes on Mars

Gee – I wonder where they got this idea. If you’ve seen the movie, The Martian, you obviously know!

With dangerous amounts of radiation, a thin atmosphere and frigid temperatures, the first people to land on Mars will have a fight on their hands to survive. And if we do figure out how to endure these harsh conditions, what will we do when dinner time rolls around? To explore ways these pioneers might be able to live off the land, scientists have been trying to grow potatoes on Earth in Mars-like conditions. The early results are now in and are described as positive. read more

ARCA Space Corporation has announced its linear aerospike engine is ready to start ground tests as the company moves towards installing the engine in its Demonstrator 3 rocket. Designed to power the world’s first operational Single-Stage-To-Orbit (SSTO) satellite launcher, the engine took only 60 days to complete from when fabrication began. read more

Say Goodbye to Fillings

There’s not a whole lot to like about fillings, what with the prodding, scraping and jabbing and all. And that’s before the drill even comes out (followed by the bill at the end). Tending to our cavities might one day be a much more comfortable experience, with scientists discovering that a type of Alzheimer’s drug can actually stimulate stem cells within the tooth pulp to promote natural repair instead.

The drug in question is a small molecule called a glycogen synthase kinase (GSK-3) inhibitor. read more

In 1996, scientists discovered what may be the strangest stone ever found, in an equally strange section of the Sahara desert that’s littered with unique yellow glass. Nicknamed the Hypatia stone, the relic was later found to be extraterrestrial in origin, but was unlike any known kind of meteorite or comet. A new study has deepened the mystery even further, finding that Hypatia could predate the formation of the Solar System, or have interstellar origins. read more

Lobsters are the Key To Jellyfish Blooms

Jellyfish blooms are regarded by some as an ecological menace, but they may sound the dinner gong for the commercially valuable Norway lobster. Recently, a team of scientists from Heriot-Watt University in Edinburgh have photographed the tasty crustacean in the waters off western Norway chowing down on jellyfish carcasses, suggesting that they could form a major part of its diet.

The 25-cm (10-in) Norway lobster (Nephrops norvegicus), also known as the Dublin Bay prawn, langoustine, or scampi, is the most important commercial crustacean in Europe, responsible for revenues of £78 million (US$105 million) to Scotland alone. They’re remarkably abundant in the north-eastern Atlantic and parts of the Mediterranean, and they’re cheaper than the larger common lobster. Each year 60,000 tonnes of them are hauled in with half taken in British waters. read more
