Watching individual neurons respond to magnetic therapy

June 30, 2014 9:16 am | by EurekAlert! | Comments

Engineers and neuroscientists at Duke University have developed a method to measure the response of an individual neuron to transcranial magnetic stimulation (TMS) of the brain. The advance will help researchers understand the underlying physiological effects of TMS -- a procedure used to treat psychiatric disorders....

Noninvasive brain control

June 30, 2014 9:12 am | by EurekAlert! | Comments

Optogenetics, a technology that allows scientists to control brain activity by shining light on neurons, relies on light-sensitive proteins that can suppress or stimulate electrical signals within cells. This technique requires a light source to be implanted in the brain, where it can reach the cells to be controlled....

Single-pixel 'multiplex' captures elusive terahertz images

June 30, 2014 9:10 am | by EurekAlert! | Comments

A novel metamaterial enables a fast, efficient and high-fidelity terahertz radiation imaging system capable of manipulating the stubborn electromagnetic waves, advancing a technology with potential applications in medical and security imaging, a team led by Boston College researchers reports in the online edition of the journal Nature Photonics....


Bending the rules

June 30, 2014 9:02 am | by EurekAlert! | Comments

For his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota, Yu Chen, now a postdoctoral researcher at UC Santa Barbara, developed a novel way to fabricate superconducting nanocircuitry. However, the extremely small zinc nanowires he designed did some unexpected — and sort of funky — things....

Study finds videoconferencing with family, friends lowers stress for pediatric patients

June 30, 2014 8:55 am | by EurekAlert! | Comments

To ease isolation during extended hospitalizations, UC Davis Children's Hospital offers secure videoconferencing for patients and families. While anecdotal accounts have suggested the Family-Link program enhances quality of life during long hospital stays, clinicians wondered if the technology also offered clinical benefits....

Underwater robot event ends at marine sanctuary

June 30, 2014 8:52 am | by Associated Press | Comments

Student teams controlling underwater robots from the United States, Canada and Russia were the winners Saturday in a global competition at the only federal freshwater marine sanctuary in the United States. The high school and university teams were among 60 from 18 states and 13 countries....

NASA to launch global warming satellite after loss

June 30, 2014 8:49 am | by ALICIA CHANG, AP Science Writer | Comments

Five years after a NASA satellite to track carbon dioxide plunged into the ocean after liftoff, the space agency is launching a carbon copy - this time on a different rocket. The $468 million mission is designed to study the main driver of climate change emitted from smokestacks and tailpipes....


Cosmic caffeine: Astronauts getting espresso maker

June 27, 2014 3:55 pm | by MARCIA DUNN, AP Aerospace Writer | Comments

Talk about a cosmic caffeine jolt. The International Space Station is getting a real Italian espresso machine. Astronauts of all nationalities - but especially the Italians - have long grumbled about the tepid instant coffee served in pouches and drunk with straws 260 miles above Earth....


New form of brain signaling affects addiction-related behavior

June 27, 2014 3:47 pm | by EurekAlert! | Comments

University of Iowa researchers have discovered a new form of neurotransmission that influences the long-lasting memory created by addictive drugs, like cocaine and opioids, and the subsequent craving for these drugs of abuse. Loss of this type of neurotransmission creates changes in brains cells that resemble the changes caused by drug addiction....

Touchless technology in the operating theater

June 27, 2014 12:59 pm | by Lancaster University | Comments

Pioneering work using touchless technology for vascular surgery is now being extended to neurosurgery.Dr Mark Rouncefield and Dr. Gerardo Gonzalez from the School of Computing and Communications at Lancaster University were part of a collaborative team from Microsoft Research....

North Korea tests new precision-guided missiles

June 27, 2014 12:50 pm | by Hyung-Jin Kim, Associated Press | Comments

North Korea said Friday that leader Kim Jong Un has guided the test launches of its newly developed precision guided missiles, in a possible reference to three short-range projectiles South Korean officials say the North fired toward its waters a day earlier....


'Compressive sensing' provides new approach to measuring a quantum system

June 27, 2014 12:47 pm | by EurekAlert! | Comments

In quantum physics, momentum and position are an example of conjugate variables. This means they are connected by Heisenberg's Uncertainty Principle, which says that both quantities cannot be simultaneously measured precisely. Recently, researchers have been developing novel techniques....

Diamond plates create nanostructures through pressure, not chemistry

June 27, 2014 12:44 pm | by EurekAlert! | Comments

You wouldn't think that mechanical force — the simple kind used to eject unruly patrons from bars, shoe a horse or emboss the raised numerals on credit cards — could process nanoparticles more subtly than the most advanced chemistry. Yet, in a current paper in Nature Communications ...


Packing hundreds of sensors into a single optical fiber for use in harsh environments

June 27, 2014 12:34 pm | by EurekAlert! | Comments

By fusing together the concepts of active fiber sensors and high-temperature fiber sensors, a team of researchers at the University of Pittsburgh has created an all-optical high-temperature sensor for gas flow measurements that operates at record-setting temperatures above 800 degrees Celsius....

Capturing CO2 emissions needed to meet climate targets

June 27, 2014 12:28 pm | by EurekAlert! | Comments

This is shown by the most comprehensive study to date on technology strategies to combat climate change, published in a special issue of the journal Climatic Change. It is based on the analysis of 18 computer models by an international team of scientists under the roof of the Stanford Energy Modelling Forum (EMF 27)....
