Running roaches, flapping moths create a new physics of organisms

Sand-swimming lizards, slithering robotic snakes, dusk-flying moths and running roaches all have one thing in common: They're increasingly being studied by physicists interested in understanding the shared strategies these creatures have developed to overcome the challenges of moving though their environments.

Rogue wave analysis supports investigation of the El Faro sinking

A new analysis done to support the investigation into the 2015 sinking of the El Faro cargo ship has calculated the likelihood of a massive rogue wave during Hurricane Joaquin in October of that year - and demonstrated a new technique for evaluating the probability of rogue waves over space and time.

One-way track for microwaves based on mechanical interference

Researchers use interference in the motion of a micrometer-size drum to route microwave signals in a single direction.

Nonlinear physics bridges thoughts to sounds in birdsong

The beautiful sound of birdsongs emerging from the trees is a wonderful example of how much nature can still teach us, even as much about their origins are still mysterious to us. About 40 percent of bird species learn to vocalize when they are exposed to a tutor, a behavior of interest to many neurologists and neurobiologists. The other 60 percent can vocalize instinctually in isolation. The variety across species, and the relationship between the nervous system and biomechanics makes birdsong production a complex process to unravel and understand.

Cost effective quantum moves a step closer

Researchers have taken an important step towards enabling quantum networks to be cost-effective and truly secure from attack. The experiments prove the viability of a measurement-device-independent quantum key distribution (QKD) system, based on readily available hardware.

Novel strategy for chirality controlled synthesis of single-walled carbon nanotubes

Researchers have developed a novel strategy for controlling chirality of single-walled carbon nanotubes.

Optical, electrical bistability study sheds light on next-gen high speed data transfer

Today, electrical bistable devices are the foundation of digital electronics, serving as building blocks of switches, logic gates and memories in computer systems. However, the bandwidth of these electronic computers is limited by the signal delay of time constants important to electronic logic operations. In an attempt to mitigate these problems, scientists have considered the development of an optical digital computer, and one team has gone so far as to demonstrate the optical and electrical bistability for switching in a single transistor.

2-D Electronics' metal or semiconductor? Both

Researchers produced the first 2-D field-effect transistor (FET) made of a single material.

New approach boosts performance in thermoelectric materials

Thermoelectric materials are considered a key resource for the future - able to produce electricity from sources of heat that would otherwise go to waste, from power plants, vehicle tailpipes and elsewhere, without generating additional greenhouse gases. Although a number of materials with thermoelectric properties have been discovered, most produce too little power for practical applications.

New quantum phenomena in graphene superlattices

Researchers have just shown the first new type of quantum oscillation to be reported for thirty years. It is the first of its kind to be present at high temperature and on the mesoscale and sheds light on the Hofstadter butterfly phenomenon.
