To create the innovative camera, which also allows for a practically infinite depth of field, the scientists used stretchable electronics and a pliable sheet of microlenses made from a material similar to that used for contact lenses. The researchers described the camera in an article published today in the journal Nature.

Insect-inspired camera captures wide field of view with no distortion, according to CU-Boulder study
To grow more food more sustainably we need to make plants better at recruiting nutrients and water from soil to seed, according to 12 leading plant scientists writing in Nature.
Essential to this are proteins called membrane transporters. Transporters also effectively carry high-energy molecules to where they are needed, help plants resist pathogens and make plants more tolerant to adverse conditions. One challenge is to make crops do these things simultaneously.
Inspired by the complex fly eye, an interdisciplinary team led by researchers at the University of Illinois at Urbana-Champaign and Northwestern University has developed a hemispherical digital camera with nearly 200 tiny lenses, delivering exceptionally wide-angle field of view and sharp images.
An interdisciplinary team of researchers has created the first digital cameras with designs that mimic those of ocular systems found in dragonflies, bees, praying mantises and other insects. This class of technology offers exceptionally wide-angle fields of view, with low aberrations, high acuity to motion, and nearly infinite depth of field.
PITTSBURGH—Amphibian populations living close to agricultural fields have become more resistant to a common insecticide and are actually resistant to multiple common insecticides, according to two recent studies conducted at the University of Pittsburgh.
A recent study involving the University of Southampton has investigated public perception of how waste disposal sites affect residents living nearby.
Public opinion of waste management facilities can influence where sites are located and how waste management services are delivered. Obtaining the support of communities around municipal solid waste (MSW) facilities is an important part of the successful operation of these services. One common complaint from local communities concerns unpleasant smells emitted from waste disposal facilities, such as from landfill sites.
Just as people have embraced computers and smart phones, they may also give their blessing to talking tissue boxes and other smart objects, according to Penn State researchers.
"Smart objects will become more and more a part of our daily lives," said S. Shyam Sundar, Distinguished Professor of Communications and co-director of the Media Effects Research Laboratory. "We believe the next phase is that objects will start talking and interacting with humans, and our goal is to figure out the best ways for objects to communicate with humans."
A UCLA-led study of adolescents receiving treatment for methamphetamine dependence has found that girls are more likely to continue using the drug during treatment than boys, suggesting that new approaches are needed for treating meth abuse among teen girls.
Results from the study, conducted by the UCLA Center for Behavioral and Addiction Medicine and the community-based substance abuse treatment program Behavioral Health Services Inc., are published in the April edition of the Journal of Adolescent Health.
PITTSBURGH—Technology blogs have been abuzz that smartwatches may soon be on their way from companies such as Apple, Google, Samsung and Microsoft. But as capable as these ultra-small computers may be, how will users enter an address, a name, or a search term into them? One solution is an iterative zooming technique developed and tested by researchers at Carnegie Mellon University.
DURHAM, N.C. -- When it comes to deciding which light bulb to buy, a label touting the product's environmental benefit may actually discourage politically conservative shoppers.
Dena Gromet and Howard Kunreuther at The University of Pennsylvania's Wharton School and Rick Larrick at Duke University's Fuqua School of Business conducted two studies to determine how political ideology affected a person's choice to buy energy-efficient products in the United States.
Writing in Nature Communications, the researchers report the first graphene-based transistor with bistable characteristics, which means that the device can spontaneously switch between two electronic states. Such devices are in great demand as emitters of electromagnetic waves in the high-frequency range between radar and infra-red, relevant for applications such as security systems and medical imaging.
From methanol to formaldehyde - this reaction is the starting point for the synthesis of many everyday plastics. Using catalysts made of gold particles, formaldehyde could be produced without the environmentally hazardous waste generated in conventional methods. Just how the mysterious gold catalyst works has been found out by theoretical and experimental researchers at the Ruhr-Universität Bochum in a cooperation project. In the international edition of the journal "Angewandte Chemie" they report in detail on what happens on the gold surface during the chemical reaction.
Research into the complementary therapies evening primrose oil and borage oil shows little, if any, benefit for people with eczema compared with placebo, according to a new systematic review. The authors, who published their review in The Cochrane Library, conclude that further studies on the therapies would be difficult to justify.
CHAMPAIGN, Ill. — When designing product lines, one important decision marketing and manufacturing managers must consider is whether to use common or product-specific components. While the use of common components can reduce manufacturing costs, firms have traditionally shied away from that strategy over concerns of intensifying what scholars call "product cannibalization."
HOUSTON – (April 29, 2013) – Squeeze a piece of silicone and it quickly returns to its original shape, as squishy as ever. But scientists at Rice University have discovered that the liquid crystal phase of silicone becomes 90 percent stiffer when silicone is gently and repeatedly compressed. Their research could lead to new strategies for self-healing materials or biocompatible materials that mimic human tissues.
A paper on the research appeared this month in Nature's online journal Nature Communications.
