New technique would allow a petabyte of data on a single disc

Data storage and preservation are no longer restricted to the needs of individual users, or even of companies or governments large and small. Instead they are the only remaining approach to preserving the history associated with the evolution of the digital age, and possibly the post-human era to follow. A research team headed by Prof. Min Gu of Swinburne University of Technology has developed a new data storage method that may be of considerable use for such civilization-sized concerns by putting a petabyte of information on a DVD-sized polymer disk.

Potentially very-useful "polymer opals" change color when stretched

Some of the most vividly colored materials in nature, including things like butterfly wings, don’t obtain their color from pigment. Instead, their internal structure reflects light at a given wavelength, producing a specific color. Opals are another example of something that utilizes this effect. In collaboration with Germany’s Fraunhofer Institute for Structural Durability and System Reliability, scientists from the University of Cambridge have now copied the colorful nanostructure of the opal. The result is a flexible, colorful material that won’t fade over time, that changes color when stretched, and that could have many applications. Read More

Planned Vikings Stadium will have world's largest transparent roof

The Minnesota Vikings American football team has announced the final design for a new stadium to built in the Minneapolis city center that will feature the world’s largest transparent roof. This feat will be achieved using state-of-the-art polymer instead of glass to resist the extremes of Minnesota’s climate, while providing views of the city skyline and a sense of openness for fans and players alike.

Swarms of tiny "microgrippers" used to perform biopsies

When procuring tissue samples for medical diagnosis, doctors have been confined to bulky and invasive forceps. But with recent successful experiments in pigs, we may see doctors switching from the single forceps to hordes of a thousand "microgrippers." These metal discs, each only 300 micrometers in size, are designed to snip bits of tissue when introduced en masse into the body and then be easily retrieved by a doctor. Their small size, added to the fact that they need no batteries, tethers or wires, belies their complexity and autonomy in function, which could allow the microgrippers to provide diagnoses earlier, more easily, and with less trauma.

Sulfur-based polymers open door to a new class of battery

Whether sulfur is a by-product or a waste product of oil refinement and coal combustion depends on how you slice it. Certainly, some of that sulfur can be put to use producing sulfuric acid, fertilizer and other chemicals, but much of it is accumulating into stockpiles that are expensive to maintain (due to the need to neutralize acidic run-off). Researchers at the University of Arizona think more of that sulfur could be put to use thanks to a new chemical process that uses sulfur to make plastics that may one day be used to make a new generation of lighter, more efficient lithium-sulfur batteries.
