Tech Xplore / Multiscreen social TV would enrich traditional viewing experience
Following the trend of the merging of TV and Internet, researchers have proposed a new way to interact with people over the Internet while watching TV. The new paradigm involves using a second screen (such as a tablet or ...
Phys.org / Non-volatile memory improves energy efficiency by two orders of magnitude
(Phys.org) —By using voltage-generated stress to switch between two magnetic states, researchers have designed a new non-volatile memory with extremely high energy efficiency—about two orders of magnitude higher than that ...
Phys.org / Physicists propose superabsorption of light beyond the limits of classical physics
(Phys.org) —In a well-known quantum effect called superradiance, atoms can emit light at an enhanced rate compared to what is possible in classical situations. This high emission rate arises from the way that the atoms interact ...
Phys.org / New insights into 'switchable water' have implications for water purification and desalination
(Phys.org) —Water is rarely pure; instead, it often contains dissolved ions or is mixed with other liquids. Scientists can change the composition of water by separating its mixtures, which is most commonly performed by distillation. ...
Phys.org / Scientists fabricate defect-free graphene, set record reversible capacity for Co3O4 anode in Li-ion batteries
(Phys.org) —Graphene has already been demonstrated to be useful in Li-ion batteries, despite the fact that the graphene used often contains defects. Large-scale fabrication of graphene that is chemically pure, structurally ...
Phys.org / Color hologram uses plasmonic nanoparticles to store large amounts of information
(Phys.org) —In the 4th century, the Romans built a special glass cup, called the Lycurgus cup, that changes colors depending on which way the light is shining through it. The glass is made of finely ground silver and gold ...
Phys.org / Highly conductive organic metal looks promising for disposable electronic devices
(Phys.org) —Although organic materials are often used as semiconductors, such as in organic LEDs and organic transistors, organic materials that have an electrical conductivity as high as that of metals are still very scarce. ...
Phys.org / Researchers build first 3D magnetic logic gate
(Phys.org) —The integrated circuits in virtually every computer today are built exclusively from transistors. But as researchers are constantly trying to improve the density of circuits on a chip, they are looking at alternative ...
Phys.org / Massive neutrinos may not bring about cosmological concordance after all
(Phys.org) —Scientists have many tools for measuring the cosmic structures of the universe, which includes structures such as galaxies, galaxy clusters, and intergalactic gas. Cosmic structures can be observed directly, such ...
Phys.org / Study explains how Maxwell's demon uses mutual information to extract work
(Phys.org) —Maxwell's demon, the hypothetical doorman that controls how particles travel between two chambers in an attempt to decrease entropy, is at its heart a feedback-controlled system. The demon makes measurements on ...
Tech Xplore / Salinity-gradient-power cell's surprisingly high voltage gives it best cost-per-watt of its kind
Several different methods exist for generating electricity from the mixing of salt water and fresh water, which is also called salinity gradient power (SGP). One method uses concentration cells, in which two semi-cells separated ...
Medical Xpress / Diseases, symptoms, genes, and proteins linked together in giant network
(Medical Xpress)—The first indication that you're sick is typically one or more symptoms: perhaps a cough, fever, abdominal pain, etc. Symptoms are high-level clinical manifestations of a disease that, at a lower level, is ...
Medical Xpress / Binary bacteria "bits" in human intestines associated with health status
The human gut contains hundreds of different types of bacteria, which vary widely among individuals. Understanding these variations is a complex and relatively new area of research. Now in a new study, researchers have found ...
Phys.org / Test of equivalence principle searches for effects of spin-gravity coupling
(Phys.org) —Einstein's equivalence principle states that an object in gravitational free fall is physically equivalent to an object that is accelerating with the same amount of force in the absence of gravity. This principle ...
Phys.org / Entanglement between particle and wave-like states of light resembles Schrodinger's cat experiment (Update)
(Phys.org) —While entangling cats with atoms is not exactly an active area of research in any physics lab today (as far as anyone knows), many physicists are working on a close analogy of Schrödinger's cat experiment. That ...
