March 18, 2015 12:03 pm | by George Hunka, Tel Aviv Univ. | News | Comments

From computers, tablets and smartphones to cars, homes and public transportation, our world is more digitally connected every day. The technology required to support the exchange of massive quantities of data is critical. That's why scientists and engineers are intent on developing faster computing units capable of supporting much larger amounts of data transfer and data processing.

Minimal device maximizes macula imaging

March 18, 2015 7:49 am | by Mike Williams, Rice Univ. | Videos | Comments

A smart and simple method developed at Rice Univ. to image a patient’s eye could help monitor eye health and spot signs of macular degeneration and diabetic retinopathy, especially in developing nations. The patient-operated, portable device invented at Rice is called mobileVision. It can be paired with a smartphone to give clinicians finely detailed images of the macula, without artificially dilating the pupil.

Data structures influence speed of quantum search in unexpected ways

March 17, 2015 3:25 pm | by Susan Brown, Univ. of California, San Diego | News | Comments

Using the quantum property of superposition, quantum computers will be able to find target items within large piles of data far faster than conventional computers ever could. But the speed of the search will likely depend on the structure of the data. Such a search would proceed as a quantum particle jumps from one node of a connected set of data to another. Intuition says that the search would be fastest in a highly connected database.

“Smart bandage” detects bed sores before they are visible

March 17, 2015 2:23 pm | by Sarah Yang, Univ. of California, Berkeley | Videos | Comments

Engineers at the Univ. of California, Berkeley, are developing a new type of bandage that does far more than stanch the bleeding from a paper cut or scraped knee. Thanks to advances in flexible electronics, the researchers have created a new “smart bandage” that uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes, and while recovery is still possible.

Graphene membrane could lead to better fuel cells, water filters

March 17, 2015 12:32 pm | by Walt Miss, Penn State Univ. | Videos | Comments

An atomically thin membrane with microscopically small holes may prove to be the basis for future hydrogen fuel cells, water filtering and desalination membranes, according to a group of 15 theorists and experimentalists. The team tested the possibility of using graphene as a separation membrane in water and found that naturally occurring defects allowed hydrogen protons to cross the barrier at unprecedented speeds.

New insights into radiation damage evolution

March 16, 2015 3:02 pm | by Nancy Ambrosiano, Los Alamos National Laboratory | News | Comments

Two reports from Los Alamos National Laboratory in Scientific Reports are helping crack the code of how certain materials respond in the highly damaging radiation environments within a nuclear reactor. The goal of these efforts is to understand at an atomistic level just how materials develop defects during irradiation, and how those defects evolve to determine the ultimate fate of the material.

March 16, 2015 8:58 am | by Larry Rivais, Univ. of Massachusetts, Amherst | News | Comments

New modeling and analyses of fault geometry in the Earth's crust by geoscientist Michele Cooke and colleagues at the Univ. of Massachusetts Amherst are advancing knowledge about fault development in regions where one geologic plate slides past or over another, such as along California's San Andreas Fault and the Denali Fault in central Alaska.

Maps predict strength of structures

March 16, 2015 7:36 am | by Mike Williams, Rice Univ. | Videos | Comments

Mother-of-pearl, the iridescent layer in the shells of some mollusks, inspired a Rice Univ. study that will help scientists and engineers judge the ultimate strength, stiffness and toughness of composite materials for anything from nanoscale electronics to buildings.

New technology may double radio frequency data capacity

March 13, 2015 3:34 pm | by Holy Evarts, Columbia Univ. School of Engineering and Applied Science | News | Comments

A team of Columbia Engineering researchers has invented a technology, full-duplex radio integrated circuits (ICs), that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times or at the same time but at different frequencies.
