Fake muscles put new twist on artificial hearts

When you think of a beating heart, you probably just picture it flexing in and out, sort of like a rubber ball being squeezed by an invisible hand. In fact, though, its motion is more similar to that of a dish rag being wrung out, with the top of the organ twisting in a clockwise direction while the bottom contracts counterclockwise. It's known as the left ventricular twist, and scientists have now replicated it using artificial muscles. The research could lead to better-functioning cardiac implants, among other things.

EDAG's Genesis: The 3D printed car of the future

Of all the technologies to have emerged from the digital renaissance, additive manufacturing (3D printing) has the potential to be the most disruptive. A perfect example of the way 3DP will change the way we make things will be displayed at the Geneva Motor Show this week when EDAG, the world’s largest independent engineering partner to the mobility industry, displays an example of a printed automobile. The Genesis is more a conceptual sculpture than an automobile, but it will give you a taste of what the world's leading manufacturers might be producing a decade or two from now.Read More

Study of ant necks could help develop stronger robots

Though ants have long been known to carry loads many times their own weight, a new study has cast light on the extent of this strength and the mechanics responsible for it. Research conducted by a team from The Ohio State University suggests an ant can lift 5,000 times its own body weight, with its neck bearing most of the load, providing a potential blueprint for the development of much stronger robots.Read More

Robot thinks like a bee, to learn from what it sees

Because of bees' small size, maneuverability and almost machine-like swarm mentality, it shouldn't come as a surprise that scientists are developing tiny flying robots based on the insects. In order to navigate autonomously, however, those robots' artificial bee brains will have to be capable of identifying objects in their environment, and reacting accordingly. Well, thanks to research recently conducted in Berlin, they may soon be able to do so. Read More

Cod inspire potentially life-saving cold storage tech for human blood

How is it possible that cold-blooded fish such as cod can live in Arctic waters without just freezing solid? As it turns out, they've got proteins in their bloodstream that act as a sort of antifreeze. British scientists have now copied the fashion in which those proteins work, to create a process by which donated human blood could be frozen for storage, then quickly made available for transfusion.

Super-tough glass based on mollusk shells

In the future, if you drop a glass on the floor and it doesn't break, thank a mollusk. Inspired by shellfish, scientists at Montreal's McGill University have devised a new process that drastically increases the toughness of glass. When dropped, items made using the technology would be more likely to deform than to shatter. Read More

Toxin-detection system inspired by turkeys

Turkeys may not be everyone's idea of beautiful birds, but they certainly have colorful skin on their heads. What's more, that skin changes color with the animal's mood. Scientists at the University of California, Berkeley, have now copied the process by which those color changes occur, and used it to create a biosensor that could be used to detect airborne toxins.
