Portable “paper machine” can diagnose disease on the cheap

July 17, 2015 7:35 am | by American Chemical Society | Comments

In the U.S. and other industrialized nations, testing for infectious diseases and cancer often requires expensive equipment and highly trained specialists. In countries where resources are limited, performing the same diagnostics is far more challenging. To address this disparity, scientists are developing a portable, low-cost “paper machine” for point-of-care detection of infectious diseases, genetic conditions and cancer.

Trapped light orbits within intriguing material

July 17, 2015 7:25 am | by Susan Brown, Univ. of California, San Diego | Comments

Light becomes trapped as it orbits within tiny granules of a crystalline material that has increasingly intrigued physicists, a team led by Univ. of California, San Diego, physics professor Michael Fogler has found. Hexagonal boron nitride, stacked layers of boron and nitrogen atoms arranged in a hexagonal lattice, has recently been found to bend electromagnetic energy in unusual and potentially useful ways.

Satisfying the hunger for a lightweight yet strong material

July 16, 2015 4:00 pm | by New York Univ. | Comments

A team of researchers reports success in pioneering tests of a layered material with a lightweight metal matrix syntactic foam core that holds significant potential for automobiles, trains, ships and other applications requiring lightweight structural components that retain their strength even when bent or compressed.

A most singular nano-imaging technique

July 16, 2015 3:00 pm | by Lynn Yarris, Lawrence Berkeley National Laboratory | Comments

Just as proteins are one of the basic building blocks of biology, nanoparticles can serve as the basic building blocks for next generation materials. In keeping with this parallel between biology and nanotechnology, a proven technique for determining the three dimensional structures of individual proteins has been adapted to determine the 3-D structures of individual nanoparticles in solution.

Toward cheaper water treatment

July 16, 2015 10:46 am | by Rob Matheson, MIT News Office | Comments

Hydraulic fracturing, or “fracking,” produces a lot of wastewater. Drilling one well requires millions of gallons of water that’s injected into the ground to loosen rocks and release oil. While some is reused, much of the produced water is discarded into deep injection wells, and clean water is purchased again and again.

Deciphering the brain’s noisy code

July 16, 2015 7:49 am | by Jade Boyd, Rice Univ. | Comments

By analyzing the signals of individual neurons in animals undergoing behavioral tests, neuroscientists have deciphered the code the brain uses to make the most of its inherently “noisy” neuronal circuits. The human brain contains about 100 billion neurons, and each of these sends signals to thousands of other neurons each second. Understanding how neurons work is important to better understand how humans think.

Old astronomic riddle soon to be solved

July 16, 2015 7:34 am | by Olivia Poisson, Univ. of Basel | Comments

Scientists were able to identify, for the first time, a molecule responsible for the absorption of starlight in space: the positively charged Buckminsterfullerene, or so-called football molecule. Almost 100 years ago, astronomers discovered that the spectrum of star light arrived on earth with dark gaps, so-called interstellar bands. Ever since, researchers have been trying to find which type of matter in space absorbs the light.

Molecular fuel cell catalysts hold promise for efficient energy storage

July 16, 2015 7:26 am | by Libby Dowdall, Univ. of Wisconsin-Madison | Comments

In the quest for better, less expensive ways to store and use energy, platinum and other precious metals play an important role. They serve as catalysts to propel the most efficient fuel cells, but they are costly and rare. Now, a metal-free alternative catalyst for fuel cells may be at hand. A team of chemists from the Univ. of Wisconsin-Madison has introduced an approach that uses a molecular catalyst system instead of solid catalysts.

Breaking the terahertz barrier for graphene nanoelectronics

July 16, 2015 7:11 am | by Max Planck Institute for Polymer Research | Comments

A team of scientists has discovered that electrical conduction in graphene on the picosecond timescale is governed by the same basic laws that describe the thermal properties of gases. This much simpler thermodynamic approach to the electrical conduction in graphene will allow scientists and engineers not only to better understand but also to improve the performance of graphene-based nanoelectronic devices.
