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.
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.
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.
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.
An unknown blast shook the desolate New Mexico desert on July 16, 1945, unsettling the historic Hispanic village of Tularosa.
Car parts maker Magna International Inc. is buying Getrag, a German-based manufacturer of automotive transmissions, in a 1.75 billion euro ($1.9 billion) deal.
Healthy brain, muscle, eye and heart cells would improve the lives of tens of thousands of people around the world with debilitating mitochondrial diseases.
A technique devised by UCLA researchers could help scientists better understand a tiny — but potentially important — component of next-generation electronic devices.
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.
The revolution that optogenetics technology has brought to biology — neuroscience in particular — could be transformed all over again if a new project getting underway at Brown University and Central Michigan University (CMU) is successful.
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.
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.
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.
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.
President Barack Obama set a goal of bringing high-speed Internet to most schools by 2017. Now he's promoting a new program to help close the digital divide even further by bringing that faster Internet to more people, particularly students who live in public and assisted housing.
