With the advancements in 3D printing, it only seems like a matter of time until it starts to actively affect our lives. Especially prosthetics may be revolutionized by 3D printing, as we’ve already seen time and time again. Now, a group of dentists believe they can 3D print teeth using a simple and cheap technique, only taking a few minutes for it.

Two students created a device that extinguishes fires with soundwaves

Fire-main

What do fires and deep sounds have in common? Not much right now, but they might have a lot in the future.Two George Mason University students have designed a device that uses sound waves to put out fires, thus potentially eliminating the need for carrying around huge quantities of water and costly cleaning operations. Here’s how it works:

Tesla Motors are out to change the world – and they’re doing it fast, and in style. Like many other of their projects, this one seemed to pop up out of nowhere: Tesla have designed a battery that can power your home and even larger utility buildings. In other words – it could take your house out of the grid.

China is the largest polluter in the world at the moment, and they’re also reaping what they sew. But you can’t accuse the Chinese for not trying to right their ways – at least some of them; in an effort to mitigate the ridiculous amounts of smog that clouds some of China’s cities, scientists have developed the first hydrogen-powered tram.

Boeing develops force field reminiscent of Star Trek

web africa

Boeing, a major aircraft and military manufacturer, just secured a patent that describes a Star Trek-like force shield, meant to protect vehicles operating in war zones. I love it when engineers are inspired by science fiction – it means that the authors really did a great job, not only at foreseeing the future, but also in offering the incentive to bring these sort of contraptions to real life.

Darwin’s ‘strangest animals’ finally classified thanks to protein sequencing

While in South American during his 1830 expedition with the HMS Beagle, Charles Darwin came across the fossils of two peculiar hoofed species which he was unable to classify properly. One was Macrauchenia, which looked like a camel with the head of an ant eater, and the other was Toxodon which had the body of rhino, the head of a hippo and the teeth of a rodent. So, was the Macrauchenia related to the camel or the ant eater? Who was Toxodon’s closet cousin, the hippo or the rhino? Darwin was puzzled and to no avail concluded these were “perhaps one of the strangest animals ever discovered”. But Darwin didn’t have the tools we have today. Now, using a ground breaking technique researchers have sequenced the collagen of a myriad of South American mammals, including Darwin’s ‘strangest animals’ and finally found their real taxonomy.

Long before T-rex claimed the top dog spot among terrestrial predators, a vicious crocodile ancestor that walked on its hind legs was at the top of the food chain during the Triassic. The fossils of the Carnufex carolinensis, also known as the the “Carolina Butcher,” were discovered decades ago in the Pekin Formation, a geological formation in North Carolina’s Chatham County. It was only recently that researchers reanalyzed the fossils and concluded they were dealing with an all new predator that roamed the Earth several million years before dinosaurs were even around.

Perfection is overrated: Flawed graphene sheets may lead to better fuel cells

crownethersf

A rather surprising study found that graphene’s imperfections can actually be used to improve fuel cell efficiency. Researchers from Northwestern University worked together with scientists of five other institutes to show that defective graphene actually works as the world’s thinnest proton channel—only one atom thick.

In a rather intriguing tweet, Tesla Motors and SpaceX CEO Elon Musk announced that he will end ‘range anxiety’ by the end of the week for the entire S series. The electric Tesla Model S is already able to travel up to 265 miles before its battery runs out of power – one of the longest driving ranges of any electric car currently on the market. Now, it seems they are preparing to take things even further.
