Mapping the optimal route between two quantum states

August 4, 2014 4:48 pm | by EurekAlert! | Comments

As a quantum state collapses from a quantum superposition to a classical state or a different superposition, it will follow a path known as a quantum trajectory. For each start and end state there is an optimal or "most likely" path, but it is not as easy to predict the path....

On-chip topological light

August 4, 2014 4:41 pm | by EurekAlert! | Comments

Topological transport of light is the photonic analog of topological electron flow in certain semiconductors. In the electron case, the current flows around the edge of the material but not through the bulk. It is "topological" in that even if electrons encounter impurities ...

Best evidence yet for coronal heating theory detected by NASA sounding rocket

August 4, 2014 4:14 pm | by EurekAlert! | Comments

Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface. The new observations of the small-scale extremely hot temperatures are consistent with only one current theory....


Uncovering the 3-D structure of a key neuroreceptor

August 4, 2014 3:41 pm | by EurekAlert! | Comments

Neurons are the cells of our brain, spinal cord, and overall nervous system. They form complex networks to communicate with each other through electrical signals that are carried by chemicals. These chemicals bind to structures on the surface of neurons that are called neuroreceptors....

Is quantum dot the next step in LCD TV evolution?

August 4, 2014 3:19 pm | by DisplaySearch | Comments

As the LCD industry matures and standardizes, industry players find it harder to differentiate. At the same time, AMOLED is competing in key markets such as smartphone and tablet PC displays, in part due to their color performance. One response to this situation is adoption of quantum dots....

Knowing what to keep and what to trash: How an enzyme distinguishes cellular messages

August 4, 2014 1:03 pm | by EurekAlert! | Comments

Every once in a while, we are forced to sort that stack of papers on the kitchen counter. Interspersed between the expired coupons and dozens of takeout menus are important documents like your car insurance or electric bill. So it isn't an option to simply drop it all....

UMD researchers develop tool to better visualize, analyze human genomic data

August 4, 2014 1:00 pm | by EurekAlert! | Comments

Scientists at the University of Maryland have developed a new, web-based tool that enables researchers to quickly and easily visualize and compare large amounts of genomic information resulting from high-throughput sequencing experiments. The free tool, called Epiviz ...

Scientists unveil unique approach to the basic concepts of solid state physics

August 4, 2014 12:55 pm | by EurekAlert! | Comments

Modern technology is based heavily on solid state devices such as semiconductors and lasers. It is important for future development to have an understanding of the basic physics underlying these types of devices. In their latest book "Crystal Symmetry, Lattice Vibrations ...


How science sizzles in the modern kitchen

August 4, 2014 12:44 pm | by EurekAlert! | Comments

Some of the world's finest chemists don't wear lab coats. Instead, they don aprons and toques, and masterfully meld their passion for cooking with a growing awareness of the science behind the culinary arts. The results are driving an extraordinary expansion....

Creating buzz about science to help solve pressing global challenges

August 4, 2014 12:42 pm | by EurekAlert! | Comments

Leading science communicators will share their latest strategies on how to capture the coveted attention of young students, the public and policymakers to strengthen the scientific enterprise. They will speak at the 248th National Meeting and Exposition of the American Chemical Society (ACS)....

Research institutions announce collaboration for sharing, standardizing neuroscience data

August 4, 2014 12:40 pm | by EurekAlert! | Comments

The Allen Institute for Brain Science, California Institute of Technology, New York University School of Medicine, the Howard Hughes Medical Institute (HHMI) and the University of California, Berkeley (UC Berkeley) are collaborating on a project aimed at making database....

Short-term environmental enrichment exposure induces maturity of newborn neurons

August 4, 2014 12:39 pm | by EurekAlert! | Comments

Many studies have shown that exposure to environmental enrichment can induce neurogenesis of the hippocampal region, thus improving learning and memory. Previous studies have demonstrated that doublecortin-positive immature neurons exist predominantly in the superficial layer....

Functional electrical stimulation improves neuronal regeneration after cerebral infarction

August 4, 2014 12:36 pm | by EurekAlert! | Comments

Previous studies have shown that proliferation of endogenous neural precursor cells cannot alone compensate for the damage to neurons and axons. From the perspective of neural plasticity, Dr. Yun Xiang and co-workers from Sun Yat-sen University in China observed the effects....


Fruit flies going high-tech: How touchscreen technology helps to understand eating habits

August 4, 2014 9:38 am | by EurekAlert! | Comments

A new study reveals surprising similarities between the way mammals and flies eat. What and how we eat is a crucial determinant of health and well-being. Model organisms such as fruit flies have provided crucial insights into how our brain decides what and how much to eat....

Nanoscale details of electrochemical reactions in electric vehicle battery materials

August 4, 2014 9:36 am | by EurekAlert! | Comments

Using a new method to track the electrochemical reactions in a common electric vehicle battery material under operating conditions, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have revealed new insight into why fast charging inhibits this material's performance....
