To evaluate in vivo physiological functions, electrophysiological signals must be monitored with high precision and high spatial or temporal resolution. Ultraflexible, multielectrode arrays (MEAs) were recently fabricated ...
One day in the not-so-distant future, light sails may hurtle through space at speeds of around 20% of the speed of light (or 60,000 km/sec), propelled not by fuel but rather by the radiation pressure from high-power lasers ...
Currently, most of the magnetic sensors used in today's computers, airplanes, cars, and other systems distort the magnetic fields that they are measuring. These distortions can cause major problems for some applications, ...
(Phys.org) —Optical transistors and switches are fundamental in both classical and quantum optical information processing. A key objective in optics research is determining and developing the structural and performance ...
(PhysOrg.com) -- Ocean waves can be incredibly strong and very difficult to block completely. When a wave moving across the ocean interacts with a buoy, the wave can be slightly dampened, but will still pass by if its wavelength ...
(PhysOrg.com) -- Critics of 3D viewing may call the technology a passing fad, but if engineers can overcome some of the challenges of today's 3D systems, 3D TV could work its way into becoming a common household product. ...
Using the Very Long Baseline Array (VLBA), astronomers have explored a nearby binary stellar system composed of two M dwarfs, known as LP 349−25AB. Results of the study, presented April 25 on the pre-print server arXiv, ...
Astronomers from the Steward Observatory in Tucson, Arizona and elsewhere report the detection of a new massive protocluster. The structure was found around a luminous quasar known as J0910–0414. The discovery was detailed ...
Using the Australian Square Kilometer Array Pathfinder (ASKAP), astronomers have discovered a new pulsar, which has received the designation PSR J1032−5804. The newfound pulsar turned out to be relatively young and highly ...
In 1991, the University of Utah Fly's Eye experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray's energy shocked astrophysicists. Nothing in our galaxy had the ...
