Making room to manufacture tiny bio-devices
UC IRVINE (US)—The next generation of miniature devices built from sensitive organic materials may be coming from specialized manufacturing facilities, like the new clean room lab at the University of California, Irvine. Scientists at the facility are able to work at a scale that is one-hundredth the diameter of a human hair. (more…)

Feather color linked to structures similar to beer foam
YALE (US)—Most colors in nature—from the color of our skin to the green of trees—are produced by pigments. But the bright blue feathers found in many birds, such as Bluebirds and Blue Jays, are instead produced by nanostructures. Under an electron microscope, these tiny structures—similar to beer foam—look like sponges. (more…)

‘Liquid’ metals could pave way for nano-scale chips
YALE (US)—A novel type of metal that is stronger and more durable than silicon or steel could prove to be the ideal material for manufacturing nano-devices, like computer chips and biomedical sensors. “Amorphous metals” known as bulk metallic glasses (BMGs) seem solid but are more like a very slow-flowing liquid that has no structure beyond the atomic level—making them ideal for molding fine details.

The photon force is with us—and it’s driving our nanomachines
YALE (US)—Science fiction writers have long envisioned sailing a spacecraft by the optical force of the sun’s light. But, the forces of sunlight are too weak to fill even the oversized sails that have been tried. Now a team led by researchers at the Yale School of Engineering & Applied Science has shown that the force of light indeed can be harnessed to drive machines—when the process is scaled to nano-proportions.

Fine print so small it’s subatomic
STANFORD (US)—How tiny is the world’s smallest writing? The letters in the words written by Standford University researchers are assembled from subatomic-sized bits as small as 0.3 nanometers—or roughly one third of a billionth of a meter.

Two-armed nanorobot captures DNA molecules
NYU (US)—Scientists from the United States and China have designed one of the world’s smallest robots. The programmable two-armed device could be used to create new DNA structures, serving as a factory of sorts for assembling the building blocks of new materials. Applications range from developing new synthetic fibers to improving data encryption.

Scanner detects earliest sign of cancer
STANFORD (US)—Early detection can be the difference between life and death for many cancer patients. A new blood scanner shows promising signs of helping doctors detect cancer at its earliest stage, allowing for early treatment and a better chance of survival.
