World’s smallest microphone is made from a single molecule

Posted by in category: materials

A team of scientists from Lund University in Sweden has figured out how to turn a single molecule into a microphone by making it capable of detecting the vibrations produced by sound waves.

This minuscule microphone works by embedding a single molecule of a substance called dibenzoterrylene (DBT) in a tiny crystal of a hydrocarbon material called anthracene. When the crystal is exposed to sound waves, the DBT molecule is disturbed by the vibrations, and it vibrates in response.

“This movement changes the interaction between the electron clouds of DBT and anthracene, which ultimately result in a slight shift in DBT’s fluorescence,” explains Sarah Zhang at Gizmodo. “By tracking the fluorescence of just a single molecule of DBT, the scientists could track the frequency of the sound.”

Aubrey de Grey: Longer lives won’t mean overpopulation

Posted by in categories: health, life extension

Aubrey de Grey wants to save lives. He wants to save as many as he possibly can, as soon as he can, and to do it he is going to fix ageing.

The prominent scientist and futurologist is on a crusade to beat ageing and when he does it will mean that we stay healthy and live longer – possibly for up to hundreds of years.

But, as de Grey emphasises, his primary goal is not just making people live longer; he wants us to live healthily, he wants to restore us to a state of health that is “fully functional in every way”. The ability to live for hundreds of years is just a side effect.

Open Source ‘Solar Pocket Factory’ Can 3D Print a Solar Panel Every 15 Seconds

Posted by in categories: 3D printing, computing, electronics, mobile phones, solar power, sustainability

Shawn Frayne and Alex Hornstein, two young inventors based in the Philippines, are taking their passion for clean free energy and developing a way to make it accessible and cheap for everyone. These guys are working restlessly to provide a product that could be used by practically anyone to make homemade solar panels.

The factory is small enough to fit on a desktop and efficient enough to produce 300k to one million panels per year, up to one every 15 seconds. By cutting out much of the labor intensive process, which represents 50% of the total cost, this machine can dramatically reduce the price of solar. Their pocket solar panel producer can change the way the world views electricity. Image credit: YouTube/SciFri

World’s strongest material acts like a tiny transistor

Posted by in categories: electronics, materials

It’s just one atom thick, but carbyne has twice the strength of its two-dimensional cousin, graphene, and three times the stiffness of a diamond. And researchers have just discovered that it can act like a transistor for new tinier electronics.

Researchers enable robots to see through solid walls with Wi-Fi (w/ Video)

Posted by in categories: internet, materials, mobile phones, robotics/AI

(Phys.org) —Wi-Fi makes all kinds of things possible. We can send and receive messages, make phone calls, browse the Internet, even play games with people who are miles away, all without the cords and wires to tie us down. At UC Santa Barbara, researchers are now using this versatile, everyday signal to do something different and powerful: looking through solid walls and seeing every square inch of what’s on the other side. Built into robots, the technology has far-reaching possibilities.

“This is an exciting time to be doing this kind of research,” said Yasamin Mostofi, professor of electrical and computer engineering at UCSB. For the past few years, she and her team have been busy realizing this X-ray vision, enabling robots to see objects and humans behind thick walls through the use of radio frequency signals. The patented allows users to see the space on the other side and identify not only the presence of occluded objects, but also their position and geometry, without any of the area. Additionally, it has the potential to classify the material type of each occluded object such as human, metal or wood.

The combination of and automated mobility can make these robots useful in situations where human access is difficult or risky, and the ability to determine what is in a given occluded area is important, such as search and rescue operations for natural or man-made disasters.

‘Cool-Burning’ Space Flames Could Make Greener Cars

Posted by in categories: energy, space, transportation

Astronauts typically try to avoid starting fires in space, but new research on the behavior of flames in orbit could have benefits closer to home. In fact, this fiery research could lead to more-efficient car engines that contribute less pollution to the environment, according to a new study.

A series of experiments aboard the orbiting complex is investigating “cool-burning” flames in space — a type of fire that burns at lower temperatures than ordinary flames on Earth. Blazes on this planet typically burn at between 2,240 degrees and 3,140 degrees Fahrenheit (1,225 degrees and 1,725 degrees Celsius). Cooler flames produced in microgravity burn at temperatures of between 440 degrees and 980 degrees Fahrenheit (227 degrees and 527 degrees Celsius).

In the space station experiments, researchers ignited droplets of heptane fuel. These types of fires are possible on Earth, but they are typically short-lived, flickering out almost immediately, the researchers said. In microgravity, though, the flames burned for several minutes. [7 Everyday Things that Happen Strangely In Space].

MIT Invented Magnetic Hairs That Can Make Water Flow Uphill

Posted by in categories: innovation, materials

Inspired by the coats of fur on some animals, researchers at MIT have developed a flexible skin-like material covered in thousands of tiny magnetic hairs that can move in varying directions in the presence of a magnetic field. That might not seem particularly useful, until MIT points out that the new material can be used to control how liquids move across its surface, even causing water to flow against the pull of gravity.

It’s a neat trick, for sure, but there are other more useful applications of this new material. The tiny magnetic micro-pillars that make up the hair can be manufactured from a fiber optic-like material allowing them to change the direction of light passing through, facilitating self-darkening windows, or revolutionary new optics for cameras. The material can also be used to create advanced artificial skins, smart waterproofing, and even a precise way to manipulate individual cells. And let’s not forget a potential radical breakthrough in self-combing toupees and wigs. [MIT].
