This smart toothbrush will clean all your teeth in just 6 seconds

Screenshot 2018-11-14 00.27.22

There are plenty of things in life that are a part of our routine. We’ve gotten used to them. They’re comfortable and familiar. And brushing your teeth is a perfect example. You expect to block out three to four minutes every morning and every night to brush every tooth one at a time until they’re squeaky clean.

But not anymore.

The creators of Unobrush have reinvented the way we brush our teeth. And, turns out, they’re absolutely crushing it on KickStarter., where the project is being crowdfunded.

This super-reflective coating keeps buildings cool so we don’t need as much AC

IMG_9186

Buildings are already being painted white to help keep them cool. As temperatures increase, this new addition to the paint could help lower our massive air conditioning energy use.

One of the ironies of climate change is that as heat waves become more common, people use more air conditioning–and those air conditioners help drive more climate change, and make things hotter. By the middle of the century, as more people around the world can afford air conditioners, the number of units could more than triple and end up using as much electricity as China uses today for its entire economy.

Engineers at the University of British Columbia have developed a new ultrasound transducer, or probe, that could dramatically lower the cost of ultrasound scanners to as little as $100. Their patent-pending innovation—no bigger than a Band-Aid—is portable, wearable and can be powered by a smartphone.

New “Super Wood” is as strong as steel

IMG_8569

Wood is great. It looks nice as a building material. It grows right out of the ground. But compared to things like concrete, marble, and steel, it’s not all that strong. Well, it didn’t used to be, anyway. Scientists have now created a “super wood” that’s strong enough to stop a bullet.

Cracked smartphone screens are about to become a thing of the past

IMG_8424

Changes in design and materials are good news for those of us with slippery fingers.

One of the biggest problems with smartphones is that they break. Screens are the most common culprit—smashed and cracked displays make up roughly 50 percent of all smartphone repairs. Water damage, malfunctioning charging ports or connectors, or nonfunctioning buttons are also popular reasons smartphone owners head to the repair shop. While talk of planned obsolescence—the idea that smartphone-makers purposefully design their products to eventually fail, forcing you to upgrade to a newer model—often comes up, these issues just happen with use over time. Over the past few years, smartphone companies have been taking small steps to make their phones more durable. Now, it seems we may be commencing an era of nearly unbreakable phones as hardware-makers develop less fragile display and body materials and continue to shore up devices against threats like dust and water.

Amazing solar panel device is now open source

Anyone who has wanted to generate their own energy and filter their own water can now do so with an amazing open source device.

Speaking on stage at Inspirefest 2018, Chinese-Canadian mechanical and electrical engineer Eden Full Goh described what inspired her to develop a cheap, easy-to-build solar panel device called the SunSaluter.

You don’t even need waves to ride this electric hydrofoil surfboard

IMG_7802

One of the biggest trends in surfing over the past few years has been the adoption of hydrofoil surfboards by some of the sports biggest names. Adding a hydrofoil to the bottom of the board creates lift and more speed, turning even ordinary waves into something that is a lot more fun and interesting to ride. But a new surfboard could eliminate the need for waves altogether, thanks to an onboard electric motor that generates all the thrust riders need.

The Fliteboard looks a lot like other hydrofoil surfboards already on the market, with one important distinction. Attached to the bottom of the foil is a small propeller that is engaged when riders fire up the built-in electric motor. When turned on, the Fliteboard is capable of reaching speeds of nearly 25 mph, while the removable battery pack — dubbed the “Flite Cell” — can give the board a range of up to 15.5 miles on a single charge. The engineers who designed the Fliteboard say that the battery is so powerful that it can actually keep the board moving for as much as an hour, depending on water conditions and the weight of the surfer.

A German student has invented an airbag for your phone: a case that detects when it’s falling and deploys springs to prevent breaks

IMG_7650

The active dampening (AD) phone case, patented by German student Philip Frenzel, is a slim alternative to bulky phone cases, but comes with a nifty trick.

So far it’s only a prototype — but the AD case can detect when the phone is falling and protract springs to make the phone bounce when it hits the ground, which should prevent any scratches or cracks on flat surfaces.

Once you pick the phone back up, you just fold the springs back in.

New wearable, high-precision brain scanner allows for patients to move around

IMG_7590

A radical new wearable magneto encephalography (MEG) brain scanner under development at the University of Nottingham allows a patient to move around, instead of having to sit or lie still inside a massive scanner.

Currently, MEG scanners* weigh around 500 kilograms (about 1100 pounds) because they require bulky superconducting sensors refrigerated in a liquid helium dewar at -269°C. Patients must keep still — even a 5mm movement can ruin images of brain activity. That immobility severely limits the range of brain activities and experiences and makes the scanner unsuitable for children and many patients.

Bose’s new $250 Sleepbuds play soothing sounds instead of music

IMG_7488

Is quality sleep worth that much cash?

After a couple years of development and early prototype testing through an Indiegogo campaign, Bose is commercially releasing its noise-masking Sleepbuds. They go on sale tomorrow, June 21st, for $250 from Amazon, Best Buy, Bose, and other retailers. The Sleepbuds are truly wireless earbuds designed to stay in your ears overnight. As you go to sleep, they play audio tracks that drown out typical evening disturbances like street noise, loud neighbors, or a snoring partner.

They don’t play music or any other audio from external devices. Period. So forget about streaming Spotify, audiobooks, or podcasts. Nor do the Sleepbuds utilize Bose’s incredible noise-cancelation tech that’s the magic ingredient in products like the popular QuietComfort headphones.

This diving system lets you stay submerged for 2 hours, no tank needed

Do you want a diving system that bridges the gap between scuba diving and snorkeling, minus the limitations of both? If so, a new Kickstarter campaign could be for you. Described by its creators as the smartest and safest hookah-diving system around, Supa Huka possesses neither the complications of scuba diving nor the restrictions of snorkeling. In its place, you get a device which allows you to dive up to 30 feet underwater for up to two hours on a single charge. No back tank required.

Record-breaking paper water purifier operates at near 100% efficiency

IMG_6918

Researchers at the University at Buffalo have created a highly efficient device that uses sunlight and black carbon-dipped paper to clean water. The paper is placed in a triangular arrangement, which enables it to vaporize and absorb water with nearly 100 percent efficiency. The simple, inexpensive technology could be deployed in regions where clean drinking water is chronically unavailable or areas that have been acutely affected by natural disasters.
