Bug's eye inspires hemispherical digital camera
Inspired by the complex fly eye, a University of Illinois at Urbana-Champaign and Northwestern University research team has developed a hemispherical digital camera with nearly 200 tiny lenses, delivering exceptionally wide-angle field of view and sharp images. The new camera -- a rounded half bubble, similar to a bulging fly eye -- has 180 microlenses mounted on it, allowing it to take pictures across nearly 180 degrees. Only a camera shaped like a bug's eye can do this.

Piezoelectric 'taxel' arrays convert motion to electronic signals for tactile imaging
Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.

Recipe for low-cost, biomass-derived catalyst for hydrogen production
Researchers at Brookhaven National Laboratory describe details of a low-cost, stable, effective catalyst that could replace costly platinum in the production of hydrogen. The catalyst, made from renewable soybeans and abundant molybdenum metal, produces hydrogen in an environmentally friendly, cost-effective manner, potentially increasing the use of this clean energy source.

Battery and memory device in 1
Resistive memory cells are regarded as a promising solution for future generations of computer memories. Unlike the building blocks of conventional hard disk drives and memories, these novel memory cells are not purely passive components but must be regarded as tiny batteries. This has been demonstrated by researchers of Jülich Aachen Research Alliance, whose findings have now been published in the prestigious journal Nature Communications.

T2 Bio publishes data supporting diagnostic test T2Candida® in Science Translational Medicine
Deadly blood infections, or sepsis, are one of the top 10 causes of death in the United States. Each hour of delayed treatment increases the mortality of patients by 8%. This new diagnostic technology, T2Candida, achieved a 25X faster time to result, reducing the detection time of the fungus that can cause sepsis, Candida, from at best 48 hours to 3 hours. This research represents the first time Candida has been identified directly from whole blood in patient samples at clinically relevant levels.

What's old is new again
While automotive and medical device manufacturing may seem unrelated, the latter has benefited from the former. For example, manufacturing techniques developed for increasing the wear resistance of metallic camshafts are routinely used in hip implants. In both applications, performance and reliability are enhanced by increasing the strength of a metal part's surface. Now, an engineer in the Bourns College of Engineering at the University of California, Riverside seeks to extend this concept to medical devices.

Nanowires grown on graphene have surprising structure
When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy. The self-assembled wires have a core of one composition and an outer layer of another, a desired trait for many advanced electronics applications.

Insights into deadly coral bleaching could help preserve reefs
Coral reefs are stressed because of climate change. Researchers from Northwestern University and The Field Museum of Natural History have discovered corals themselves play a role in their susceptibility to deadly coral bleaching due to the light-scattering properties of their skeletons. No one else has shown this before. Using optical technology designed for early cancer detection, the researchers discovered that reef-building corals scatter light in different ways to the symbiotic algae that feed the corals.

Screening detects ovarian cancer using neighboring cells
Pioneering biophotonics technology developed at Northwestern University is the first screening method to detect the early presence of ovarian cancer in humans by examining cells easily brushed from the neighboring cervix or uterus, not the ovaries themselves. The results have the potential to translate into a minimally invasive early detection method using cells collected by a swab, exactly like a pap smear.
