Link seen between seizures and migraines in the brain
(Penn State) Seizures and migraines have always been considered separate physiological events in the brain, but now a team of engineers and neuroscientists looking at the brain from a physics viewpoint discovered a link between these and related phenomena.

Celebrating the work of the 2014 Nobel Laureates
(Wiley) John Wiley & Sons, Inc., would like to congratulate all of the 2014 Nobel laureates and is proud to have published work by nine of the laureates. To celebrate their achievements Wiley has made a selection of content from the 2014 winners free to access until the end of the year.

They know the drill: UW leads the league in boring through ice sheets
(University of Wisconsin-Madison) Hollow coring drills designed and managed by UW-Madison's Ice Drilling Design and Operations program are used to extract ice cores that can analyze the past atmosphere. Shaun Marcott, an assistant professor of geoscience at UW-Madison, was the first author of a paper published today in the journal Nature documenting carbon dioxide in the atmosphere between 23,000 and 9,000 years ago, based on data from an 11,000-foot hole in Antarctica.

Lord of the microrings
(DOE/Lawrence Berkeley National Laboratory) Berkeley Lab researchers report a significant breakthrough in laser technology with the development of a unique microring laser cavity that can produce single-mode lasing on demand. This advance holds ramifications for a wide range of optoelectronic applications including metrology and interferometry, data storage and communications, and high-resolution spectroscopy.

Study shows vibrating insoles could reduce falls among seniors
(Peters Communications) Findings published in the Archives of Physical Medicine and Rehabilitation show that imperceptible vibratory stimulation applied to the soles of the feet improved balance by reducing postural sway and gait variability in elderly study participants. The vibratory stimulation is delivered by a urethane foam insole with embedded piezoelectric actuators, which generates the mechanical stimulation.

Biology meets geometry
(University of California - Santa Barbara) Architecture imitates life, at least when it comes to those spiral ramps in multistory parking garages. Stacked and connecting parallel levels, the ramps are replications of helical structures found in a ubiquitous membrane structure in the cells of the body.

Harnessing error-prone chips
(Massachusetts Institute of Technology) A new system would allow programmers to easily trade computational accuracy for energy savings.

UTA researcher uses microscaffolding injections to mend cartilage, prevent osteoarthritis
(University of Texas at Arlington) A UT Arlington bioengineering professor has received a $1.04 million grant from the US Army that aims to regenerate cartilage tissue and reduce osteoarthritis using a patient's own stem cells, spurred through the injection of microscaffolding made of biodegradable polymers.

Twenty-first Eastern Pacific tropical depression born on Oct. 30
(NASA/Goddard Space Flight Center) NOAA's GOES-West satellite captured an image of the birth of the Eastern Pacific Ocean's twenty-first tropical depression, located far south of Acapulco, Mexico.

Lawrence Livermore develops infrared camera system to view tokamak from the inside
(DOE/Lawrence Livermore National Laboratory) Lawrence Livermore National Laboratory researchers, in collaboration with General Atomics and the University of Arizona, have developed an infrared and visible camera viewing system that's able to produce wide-angle, tangential views of full poloidal (north-south direction of the magnetic field) cross-sections inside the tokamak. The camera's images provide researchers with data about the interior conditions of the DIII-D, which was built under contract for the Department of Energy. DOE provides funding for its operation.
