Micro-macro entangled 'cat states' could one day test quantum gravity

(Phys.org) —In Schrödinger's famous thought experiment, a cat's quantum state becomes entangled with the quantum state of a decaying nucleus, resulting in the odd situation that the cat is both alive and dead at the same time. The thought...Show More Summary

Solar cells made from polar nanocrystal inks show promising early performance

(Phys.org) —Achieving a balance between low-cost fabrication and high efficiency is key to the future success of solar cells. Over the past several years, researchers have been working on developing low-cost methods to manufacture solar cells. One of the most promising methods is solution processing.

Mechanobiology: Enzyme micropump autonomously delivers insulin in response to glucose levels

(Phys.org) —For next-generation smart devices, autonomy is key. These devices will be able to power themselves, independently respond to stimuli, and perform different kinds of work, all without human intervention. With these abilities, smart devices could potentially have very wide-reaching implications.

What does physics reveal about the sizes of sports fields?

(Phys.org) —From ping pong tables to golf courses, the sizes of sports fields vary widely. Although the sizes of sports fields were originally defined empirically—that is, by simply playing the sport rather than performing calculations—researchers in a new study have found that sports field sizes follow some universal laws.

Color pixels made of nanowires offer new paradigm for digital cameras

(Phys.org) —Most of today's digital cameras achieve color by using red, green, and blue Bayer color filters through which light passes on its way to the camera's image sensors, which then convert the light into electrical signals. Although...Show More Summary

Econophysics: Can antimoney prevent the next financial crisis?

(Phys.org) —Borrowing and lending money are essential interactions in a thriving economy, yet they come with their own set of risks. For instance, the credit money that is often involved in lending is thought to play a major role in causing large-scale financial crises, such as real estate collapses. Show More Summary

A cure for clashing qubits: Researchers successfully entangle different-color photons

(Phys.org) —While two-photon interference is an important way of entangling independent identical photons, it does not handle different-color photons with the same aplomb. Recently, scientists at the University of Science and Technology...Show More Summary

'Optical oracle' could quickly solve complex computing problems

(Phys.org) —The optical fiber network that spans the globe consists of millions of miles of fibers that bring us our Internet, cable TV, and telephone services. Now researchers have shown that this global network offers an untapped computing...Show More Summary

Physicists propose explanation for metals behaving badly

(Phys.org) —One of the defining properties of metals is that, the hotter the metal, the worse it conducts electricity. But while most metals obey this inverse relationship between temperature and conductivity in a straightforward way as predicted by theory, other metals do not. Show More Summary

Of mice and molecules: In vivo photoacoustic imaging using semiconducting polymer nanoparticles

(Phys.org) —Photoacoustic imaging is a hybrid biomedical imaging modality, based on the photoacoustic effect, in which non-ionizing laser pulses are delivered into biological tissues. (More specifically, in the photoacoustic effect sound waves form due to pressure changes when a material absorbs varying-intensity modulated or pulsed light. Show More Summary

Generator uses the human body as an electrode to power portable electronics

(Phys.org) —It's well-known that the human body is a good conductor of electricity, and now researchers have taken advantage of this fact to create a small generator that uses the body as an electrode to power portable devices without the need for batteries. Show More Summary

Nanostructures enhance light trapping for solar fuel generation

(Phys.org) —As the world's dependence on fossil fuels causes ever-increasing problems, researchers are investigating solar fuels as an alternative energy source. To make solar fuels, sunlight is converted into hydrogen or another type of chemical energy. Show More Summary

Proposed graphene cardboard has highly tunable properties

(Phys.org) —Carbon nanomaterials come in many different forms, such as diamond, aerogels, graphene, and soot. Sometimes carbon nanomaterials are even used as building blocks for making more complex nanomaterials. One recent example of...Show More Summary

In quantum theory of cognition, memories are created by the act of remembering

(Phys.org) —The way that thoughts and memories arise from the physical material in our brains is one of the most complex questions in modern science. One important question in this area is how individual thoughts and memories change over time. Show More Summary

Pencil drawing of a sensor actually is a sensor

Using graphite pencils to draw on regular paper, researchers can make some very inexpensive piezoresistive (PZR) sensors. Due to the piezoresistive effect, a sensor's resistance changes under an applied strain, allowing it to sense mechanical stress and pressure. Show More Summary

Ninjabot strikes with force of a mantis shrimp

Although mantis shrimp have captured the public's fascination with their ability to strike and kill their prey with stunning force, the underlying mechanisms involved in the high-speed strike are not fully understood by scientists. So a team of researchers, S. Show More Summary

Fusion, and friction, and fields! Oh, my! The rich and ubiquitous world of fluid dynamics

Fluid dynamics – a subset of the area of physics known as fluid mechanics – is concerned with the motion, or flow, of liquids and gases. Within fluid dynamics, a vortex is a region within a fluid where the flow is essentially a spinning motion about an imaginary straight or curved axis. Show More Summary

Spatial order increases cooperation in quantum prisoner's dilemma game

Although we know that cooperating with others usually brings about the best results for everyone, oftentimes being uncooperative can be more beneficial to an individual who takes advantage of others who do cooperate. One of the mostShow More Summary

Self-charging battery gets boost from nanocomposite film

(Phys.org) —In 2012, a research team at the Georgia Institute of Technology led by Professor Zhong Lin Wang fabricated the first self-charging power pack, or battery, that can be charged without being plugged into a wall socket or other source of electricity. Show More Summary

Scientists discover bulk material that exhibits monolayer behavior

(Phys.org) —Most materials behave very differently in bulk (3D) form than they do in monolayer (2D) form. The difference occurs because of weak forces holding the multiple layers of a bulk material together, which results in electronic and vibrational coupling that alters the material's properties.
