Making the most of the low light in the muddy rivers where it swims, the elephant nose fish survives by being able to spot predators amongst the muck with a uniquely shaped retina, the part of the eye that captures light. In a new study, researchers looked to the fish’s retinal structure to inform the design of a contact lens that can adjust its focus.

Imagine a contact lens that autofocuses within milliseconds. That could be life-changing for people with presbyopia, a stiffening of the eye’s lens that makes it difficult to focus on close objects. Presbyopia affects more than 1 billion people worldwide, half of whom do not have adequate correction, said the project’s leader, Hongrui Jiang, Ph.D., of the University of Wisconsin, Madison. And while glasses, conventional contact lenses and surgery provide some improvement, these options all involve the loss of contrast and sensitivity, as well as difficulty with night vision. Jiang’s idea is to design contacts that continuously adjust in concert with one’s own cornea and lens to recapture a person’s youthful vision.

The project, for which Jiang received a 2011 NIH Director’s New Innovator Award (an initiative of the NIH Common Fund) funded by the National Eye Institute, requires overcoming several engineering challenges. They include designing the lens, algorithm-driven sensors, and miniature electronic circuits that adjust the shape of the lens, plus creating a power source — all embedded within a soft, flexible material that fits over the eye.

Imagine a world with little or no concrete. Would that even be possible? After all, concrete is everywhere—on our roads, our driveways, in our homes, bridges and buildings. For the past 200 years, it’s been the very foundation of much of our planet.

But the production of cement, which when mixed with water forms the binding agent in concrete, is also one of the biggest contributors to greenhouse gas emissions. In fact, about 5 percent of the planet’s greenhouse gas emissions comes from concrete.

Next to Quantum and Biocomputing, this is one of my favorites. Cloak material to avoid radar. Unfortunatley, we cannot have access to the material for our autos; but it would be nice to have on my car sometimes when I am running late and having to drive quickly somewhere.

Two separate teams of engineers, both conducting research into meta-materials (composites not found in nature) with the intent of developing a flexible, stretchable and tunable meta-skin, are sharing their discoveries with the world. Although the two developments revolve around the same premise—manipulating electromagnetic waves so that the surface that banquets an object becomes invisible—a few exciting differences between the teams’ approaches sets their research apart.

Good news for MRIs; maybe witht he precision we also may not have to do any repeat scans as well.

Precision Glass & Optics recently announced the customization of two thin film optical components for a high-field magnetic resonance imaging (MRI) accessory. They developed the dielectric cold mirror and cylindrical prism mirror for the Real Eye Nano; an advanced visual presentation and eye-tracking system constructed of glass and plastic with a reduced size for operation in confined MRI spaces.

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.

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, 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.
