Design student Amos Dudley has always been self-conscious of his teeth, and didn't want to shell out thousands for orthodontic treatment. So, he decided to use a 3D printer to make his own braces, similar to the Invisalign system. After researching how to formulate teeth realignment calculations over 12-months, he eventually made 12 sets of aligners. Continue reading for more pictures and information.
Software engineer Asier Marzo has lead a research team that created a working tractor beam with sound. They discovered a way to levitate and manipulate small objects using only a single set of speakers that are silent to the human ear. This invention could eventually be used in developing tangible, 3D holograms made of tiny particles. "I personally think this would be very useful as a centrifuge. You can imagine spinning a living cell to separate the different components," said Marzo. Click here to view the first image in today's viral picture gallery.

Backyard scientist Ziggy Zee and friends have created a massive 27,000 joule mag-cannon that consists of two parts: the 50-pound barrel firing mechanism, and a 200-pound bank of 56 400-volt, 6000-microfarad capacitors. This makes it the most powerful DIY railgun to date. How long did it take? Just over two years, and their recent test firings include car doors and fine china.

Scientists have developed a way to grow living heart tissue - containing muscle and "blood vessels" - that beat rhythmically like a real heart on a microchip of sorts, called "AngioChip". University of Toronto Professor Milica Radisic and her research team aim to use the technology to grow various kinds of "mini organs" that function the way real human tissues do inside the body, enabling them to be used for drug testing or even for replacements. "We can create artificial heart muscles in the lab and could potentially use it to replace the damaged tissue from the patient," said Boyang Zhang, a PhD student in Radisic's lab.

A mysterious 13-foot-long sea creature washed ashore on Bonfil Beach, in the city of Acapulco, in the south-west Mexican state of Guerrero, and it's baffling researchers. Civil Guard and Fire Brigade, Rosa Camacho, reports that the animal appears that it has just died, but oddly started to rapidly decay. "We have no idea what type of animal this is, but I do know that it does not smell bad or have a fetid aroma. It is four meters long and was found on Bonfil Beach," said Camacho.

Thanks to Roll-Array, we'll soon see alternative energy in places you'd never expect, like a deserted beach. Renovagen's photovoltaic array rolls out like carpet, and can be easily transported by a standard 4x4 vehicle. When attached to the back of the vehicle, these flexible solar panels - capable of generating up to generate up to 100kWp - are pulled out of a spool and cover the ground in minutes.

Forget bringing a heavy grill to your next outdoor party, the PhotonGrill is entirely solar-powered, and designed to fold down into a backpack. It uses NASA-inspired technology to reach 500°F in just 5-minutes. Simply remove the grill from its bag when ready, inflate it, and then use the reflective parabolic mirror to concentrate the energy into a small area to begin cooking.

Vantablack is currently the world's blackest substance - made of carbon nanotubes - absorbing a maximum of 99.965% of radiation in the visible spectrum. It's comprised of a forest of vertical tubes which are "grown", which when light strikes, instead of bouncing off, it becomes trapped and is continually deflected between the tubes before eventually becoming heat. Continue reading for two more videos and additional information.
This isn't a giant geothermal spa, but rather a strange river that flows deep through the Amazon rainforest in Mayantuyacu, Peru. It has been known to boil small animals instantly, with temperatures ranging from 50-90 °C (122-194 °F), and in at least one area, it almost reaches the boiling point of 100 °C (212 °F). The locals have known about the "Boiling River" for centuries, and ancient legend has it that the hot water is unleashed by a giant serpent named Yacumama (mothers of the waters). The river's existence was officially documented in 2011 by geothermal scientist Andres Ruzo. Click here for more pictures of the boiling river.

MIT researchers have created the world's thinnest and lightest solar cell yet. It's so thin that it can be placed on a soap bubble without causing it to burst. The goal is to use these cells in wireless cell phone charging technologies, as well as adding solar arrays to mobile devices. The team decided to use flexible parylene film - similar to the cling-wrap, but at 1/10 the thickness - on glass for the first layer of the solar cell. This film is placed on top and below the ultra-thin solar cell, protecting it from dirt and damage to enhance performance.
