Even low-level PCBs change bird songs
It may not kill them outright, but low-level PCB (polychlorinated biphenyls) contamination disrupts how some birds sing their songs, report Cornell researchers.
Smaller than small: Why we measure the space between atoms
We study the movement of incredibly small things. How small is small? Think smaller than "nano." Think smaller than atoms themselves. We measure the infinitesimally small shifts in the positions of atoms ...

Breakthrough research at RMIT University is advancing transparent bendable electronics, bringing science fiction gadgets – such as unbreakable rubber-like phones, rollable tablets and even functional clothing – closer ...
Graphene could yield cheaper optical chips
Graphene—which consists of atom-thick sheets of carbon atoms arranged hexagonally—is the new wonder material: Flexible, lightweight and incredibly conductive electrically, it's also the strongest material ...
Photonics: Graphene boosts on-chip light detectors
The fabrication of high-performance light detectors—important for computers and mobile devices—using graphene integrated onto a chip is reported in three independent studies published online this week ...
Super spider silk opens way to nano medical devices
Scientists in the United States said on Tuesday they had coated spider silk with carbon nanotubes, creating a fibre that is not only super-strong but also conducts electricity.
New magnetic semiconductor material holds promise for 'spintronics'
Researchers at North Carolina State University have created a new compound that can be integrated into silicon chips and is a dilute magnetic semiconductor – meaning that it could be used to make "spintronic" devices, which ...
New connection between stacked solar cells can handle energy of 70,000 suns
(Phys.org) —North Carolina State University researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar ...
Researchers produce nanostructures with potential to advance energy devices
New types of nanostructures have shown promise for applications in electrochemically powered energy devices and systems, including advanced battery technologies.
New computer model will help design flexible touchscreens
Electronic devices with touchscreens are ubiquitous, and one key piece of technology makes them possible: transparent conductors. However, the cost and the physical limitations of the material these conductors ...
Gel-based audio speaker demonstrates capabilities of ionic conductors, long thought limited in application (w/ Video)
In a materials science laboratory at Harvard University, a transparent disk connected to a laptop fills the room with music—it's the "Morning" prelude from Peer Gynt, played on an ionic speaker.
Tunnel FET having a new architecture with potential for substantial improvement in performance
Researchers from the National Institute of Advanced Industrial Science and Technology (AIST) have demonstrated the operation of a synthetic electric field tunnel field-effect transistor with a new architecture.
New prototype device recognizes electrical properties of infected cells as signatures of disease
Researchers at MIT have found a way to detect early-stage malarial infection of blood cells by measuring changes in the infected cells' electrical properties.
Image-processing 1,000 times faster is goal of new $5M contract
Loosely inspired by a biological brain's approach to making sense of visual information, a University of Michigan researcher is leading a project to build alternative computer hardware that could process images and video ...
