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. Show More Summary

Fractal wire patterns enhance stretchability of electronic devices

(Phys.org) —Fractals—patterns defined by their scale-invariance that makes them look the same on large scales as they do on small scales—are found in nature everywhere from snowflakes to broccoli to the beating of the heart. In a new...Show More Summary

Quantum communication scheme provides guaranteed security without quantum memories

(Phys.org) —Quantum mechanics offers the potential for creating communication technologies with an inherently higher security level than today's classical technologies. Using quantum digital signatures (QDS), for example, messages can be sent to multiple recipients with the guarantee that the messages cannot be forged or tampered with.

Photons' journeys across the universe help unravel cosmological mysteries

(Phys.org) —The faint background glow that exists throughout the Universe, called the Cosmic Microwave Background (CMB), is made of photons that have been scattering since the universe was just 400,000 years old. Now in a new paper,Show More Summary

Optical data storage has virtually unlimited lifetime

(Phys.org) —Data stored on today's CDs and DVDs has a lifetime of several decades before the physical material begins to significantly decay. Researchers are working on prolonging the lifetime of stored data, but so far reaching even 100 years has been challenging. Show More Summary

The twain finally meet: Nanowires and nanotubes combined to form intracellular bioelectronic probes

(Phys.org) —Miniaturized bioelectronic probes stand to transform biology and medicine by allowing measurement of intracellular components in vivo. Recently, scientists at Harvard University and Peking University designed, fabricatedShow More Summary

Spiderman robot spins draglines to cross open space (w/ video)

(Phys.org) —Inspired by spiders' abilities to produce draglines and use them to move across open space, researchers have designed and built a robot that can do the same. Similar to Spiderman shooting a dragline from his wrist, the robot produces a sticky plastic thread that it attaches to a surface, such as a wall or tree branch. Show More Summary

It's alive! Scientists combine liquid crystals and living bacteria

(Phys.org) —The prospect of integrated living organisms into a non-living substrate has long held a compelling appeal for those investigating active matter – the study of a type of easily-deformable out of equilibrium soft matter that...Show More Summary

3-D Air-Touch display operates on mobile devices

(Phys.org) —While interactive 3D systems such as the Wii and Kinect have been popular for several years, 3D technology is yet to become part of mobile devices. Researchers are working on it, however, with one of the most recent papers demonstrating a 3D "Air-Touch" system that allows users to touch floating 3D images displayed by a mobile device. Show More Summary

Unpacking the past: Identifying a key evolutionary step in E. coli metabolism

(Phys.org) —Evolution is a process that takes place over long periods of time over which genetics and ecology may interact, producing novel phenotypic traits. Researchers previously found that after roughly 31,500 generations had passed...Show More Summary

Nanoscale heat engine exceeds standard efficiency limit

(Phys.org) —In 2012, a team of physicists from Germany proposed a scheme for realizing a nanoscale heat engine composed of a single ion. Like a macroscale heat engine, the theoretical nanoscale version can convert heat into mechanical work by taking advantage of the temperature difference between two thermal reservoirs. Show More Summary

The ties that bind: Recreating Darwinian ligand evolution in vitro

(Phys.org) —A key feature of certain chemicals is their ability to bind to other molecules – a property that emerged through evolution – but current chemical theory lacks the ability to design binders from first principles. To resolve...Show More Summary

Future solar cells may be made of wood

(Phys.org) —A new kind of paper that is made of wood fibers yet is 96% transparent could be a revolutionary material for next-generation solar cells. Coming from plants, the paper is inexpensive and more environmentally friendly than the plastic substrates often used in solar cells. Show More Summary
