Get ready for DNA-based computer chips!

Posted by in categories: chemistry, computing, electronics, materials, nanotechnology

Interesting — DNA Microchips to be released soon.

Researchers presented this incredible work at the national meeting and exposition of the American Chemical Society (ACS) in San Diego, California, on Sunday.

Adam T Woolley, professor of chemistry at Brigham Young University (BYU) said that they are planning to use DNA’s small size and base-pairing capabilities and ability to self-assemble, and direct it to make nanoscale structures that could be used for electronics.

Tiny, artificial trees could form the next generation of windmills

Posted by in categories: energy, materials, sustainability, transportation

Researchers in the US have proposed a new form of wind power: small, artificial, mechanical trees capable of producing energy from their vibrations. Working with the natural breeze, or small movements caused by other factors, the scientists hope that new forms of renewable energy can be developed in the future.

The idea is to create a device that can convert random forces – whether that’s from the footfall of pedestrians on a bridge, or a passing gust of wind – into electricity that can be used to power devices. And the researchers have found that tree-like structures made from electromechanical materials are perfect for the task.

“Buildings sway ever so slightly in the wind, bridges oscillate when we drive on them and car suspensions absorb bumps in the road,” said project leader Ryan Harne from Ohio State University. “In fact, there’s a massive amount of kinetic energy associated with those motions that is otherwise lost. We want to recover and recycle some of that energy.”

Graphene-Infused Bike Tires Automatically Get Softer While Cornering For Better Grip

Posted by in categories: materials, particle physics, robotics/AI

Graphene, that atomic-scale super material that promises to revolutionize everything from batteries to robots, is already improving the cycling world. Vittoria’s new graphene-infused Mezcal and Morsa bike tires are lightweight, thin, grippy, and everything a cyclist wants in a tire without any tradeoffs.

Choosing what tires to put on your bike usually depends on the conditions in which you’ll be riding. Larger tires provide better grip and durability, but add weight to a bike, while smaller tires are lighter and sleeker but wear out faster and provide minimal traction.

But by adding graphene—that wonder new material made of carbon atoms arranged in a strong honeycomb pattern—Vittoria’s new G+, or Graphene Plus, tires exhibit wonderful new properties. When riding on straightaways, the dual-layer makeup of the G+ tires allows them to remain firm for lower rolling resistance and added speed. But when a cyclist is braking or cornering, the tires get soft for added traction and grip.

Gates thinks quantum computing in the cloud may come in a decade

Posted by in categories: computing, internet, materials, quantum physics

I don’t believe that we’re a decade away given the advancements around Quantum infrastructure work such the Quantum Internet and Platform. Too much progress is showing me within the next 7 to 8 years is a possibility especially with the race that we’re all in.

Bill Gates did an Ask Me Anything on Reddit Tuesday and said that there’s a chance within six to ten years that “cloud computing will offer super-computation by using quantum.”

“It could help users solve some very important science problems, including materials and catalyst design,” Gates wrote.

How cancer cells fuel their growth

Posted by in categories: biotech/medical, materials

Pretty cool.

Scientists report that amino acids, not sugar, supply most building blocks for cancerous tumor cells. Cancer cells are notorious for their ability to divide uncontrollably and generate hordes of new tumor cells. Most of the fuel consumed by these rapidly proliferating cells is glucose, a type of sugar.

Scientists had believed that most of the cell mass that makes up new cells, including cancer cells, comes from that glucose. However, MIT biologists have now found, to their surprise, that the largest source for new cell material is amino acids, which cells consume in much smaller quantities.

New ‘meta-skin’ to cloak objects from radars

Posted by in category: materials

New skin for keeping you under the radar.

Because the meta-skin is stretchable, it can be pulled tight to augment the range of radar frequencies trapped by the resonators.

The project set out to prove that that electromagnetic waves — “perhaps even the shorter wavelengths of visible light” — can be adequately suppressed with flexible, tunable liquid-metal technologies. The material is made up of rows of rings, with a radius of 0.1 inches (2.5mm) and gaps of 0.04 inches (1mm). They’re filled with galinstan, a metal alloy that remains liquid at room temperatures and is less toxic than metals who share this property, such as mercury. Each resonator acts like a small curved piece of liquid wire.

The darkest material on Earth has become even darker

Posted by in categories: electronics, materials, transportation

New material improving stealth mode vehicles and planes.

When Surrey NanoSystems introduced the original Vantablack, the company said the carbon nanotube material is capable of absorbing 99.96 percent of light that touches it. It’s so dark, it can fool your eyes into seeing a smooth surface even when the nanotubes were actually grown on crumpled foil (seriously — watch the video below the fold). Well, the new version of Vantablack is darker than that. In fact, Surrey can’t even give us the percentage of light that gets absorbed, because its spectrometers can’t measure it.

In this video below (and the GIF above), you can see the material engulf the laser pointer in darkness when it moves across:
