Electric chopsticks that make low-salt food taste salty developed by Meiji University

One of the big drags of getting older is not being able to eat with abandon any more. Nowadays just looking at the amount of salt my kids pour onto their food is enough to give me heart palpitations, but it sure would be nice to indulge in those strong flavors without risking a lifestyle disease.

Food producer Kirin and Meiji University seem to agree and through extensive research have developed a pair of chopsticks that can stimulate the taste of salt in foods with low salt content. This still unnamed device does this simply by sending a weak electric current right into your food.

Concrete is a very popular building material, enough so that one of its key ingredients – sand – is in increasingly short supply. Scientists are thus now exploring the possibility of replacing that sand with glass waste that would otherwise end up in landfills.

Scientists have created new artificial microbes by combining two very different organisms into one functioning entity. The hybrid of a yeast and a bacterium adds evidence to a long-standing hypothesis on how advanced life may have evolved.

Inside the cells of complex lifeforms are tiny, separate organs called organelles, some of which have their own separate genomes to that of the larger organism. That includes the mitochondria in animals and chloroplasts in plants, both of which generate energy for the organism. A leading theory suggests that these organelles were originally separate microorganisms that were engulfed by other cells, and the two eventually entered a symbiotic relationship that paved the way for complex life to evolve.
And now a new study has recreated this process, known as endosymbiosis. Researchers from the University of Illinois Urbana-Champaign designed and engineered artificial hybrids of two microbes – a budding yeast and photosynthetic cyanobacteria.

The resulting chimera was able to photosynthesize like the bacteria to generate energy, and reproduced through budding like the yeast. The organisms were able to propagate for at least 15 to 20 generations, and the team says that the achievement lends weight to the hypothesis that complex life got its start through endosymbiosis.

Hyundai is actually building those wild unstoppable 4x4s on robot legs

The goal here is to build the most unstoppable rough-terrain vehicles on the market. As such, these things will have four electrically driven wheels, each mounted on bizarre articulating legs. These powerful robotic legs can bend or swivel at the hip, bend again at the knee and ankle, and fully rotate the wheels before they touch down as well. They're capable of lifting these vehicles or lowering them, stepping over things, stepping up and down off sheer ledges, and precisely placing the wheels on the toughest of driving surfaces.

How Much Would It Cost to Build the Great Pyramid Today?

Even with cranes, helicopters, tractors and trucks at our disposal, it would be tough to construct the Great Pyramid of Giza today. Its construction 4,500 years ago is so astounding in some people's eyes that they invoke mystical or even alien involvement. But the current theory of the building of the Great Pyramid — the notion that it was assembled from the inside out, via a spiraling internal ramp — is probably still the best construction plan.

Following that plan, we could replicate the Wonder of the Ancient World for a cool $5 billion.

Hawaii's White Sand Beaches Are Made From Parrotfish 💩
In Hawaii, where beaches are constantly ranked the best in the world, a significant portion of that pristine, white, beautiful sand is actually poop.

Yep, 💩..
Parrotfishes, or uhu in Hawaiian, are key players in regulating algae and reef life. Their parrot-like beaks and fused-together teeth are used for scraping and biting dead coral, while additional teeth in their throats help to break it all down into sand. Snorkelers can actually hear them chomping or see the bite marks they leave on rocks.
Because parrotfishes don’t have stomachs, their meals pass straight through the long intestine, exploding in a cloud of sand out the backdoor. Larger parrotfish are like sand factories, producing as much as 840 pounds of sand per year.
