For experimental physicists, quantum frustration leads to fundamental discovery      (via sciencedaily.com)     Original source 

A team of physicists recently announced that they have discovered a new phase of matter. Called the 'chiral bose-liquid state,' the discovery opens a new path in the age-old effort to understand the nature of the physical world.

Metamaterials with built-in frustration have mechanical memory      (via sciencedaily.com)     Original source 

Researchers have discovered how to design materials that necessarily have a point or line where the material doesn't deform under stress, and that even remember how they have been poked or squeezed in the past. These results could be used in robotics and mechanical computers, while similar design principles could be used in quantum computers.

New technique in error-prone quantum computing makes classical computers sweat      (via sciencedaily.com)     Original source 

Today's quantum computers often calculate the wrong answer because of noisy environments that interfere with the quantum entanglement of qubits. IBM Quantum has pioneered a technique that accounts for the noise to achieve reliable results. They tested this error mitigation strategy against supercomputer simulations run by physicists, and for the hardest calculations, the quantum computer bested the supercomputer. This is evidence for the utility of today's noisy quantum computers for performing real-world calculations.

MethaneMapper is poised to solve the problem of underreported methane emissions      (via sciencedaily.com)     Original source 

MethaneMapper is an artificial intelligence-powered hyperspectral imaging tool that researchers have developed to detect real-time methane emissions and trace them to their sources. The tool works by processing hyperspectral data gathered during overhead, airborne scans of the target area.

Schrödinger's cat makes better qubits      (via sciencedaily.com)     Original source 

Drawing from Schrodinger's cat thought experiment, scientists have built a 'critical cat code' qubit that uses bosons to store and process information in a way that is more reliable and resistant to errors than previous qubit designs.

Physicists discover an exotic material made of bosons      (via sciencedaily.com)     Original source 

Take a lattice -- a flat section of a grid of uniform cells, like a window screen or a honeycomb -- and lay another, similar lattice above it. But instead of trying to line up the edges or the cells of both lattices, give the top grid a twist so that you can see portions of the lower one through it. This new, third pattern is a moiré, and it's between this type of overlapping arrangement of lattices of tungsten diselenide and tungsten disulfide where physicists found some interesting material behaviors.

Calculation shows why heavy quarks get caught up in the flow      (via sciencedaily.com)     Original source 

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain experimental results showing heavy quarks getting caught up in the flow of matter generated in heavy ion collisions.

Whales not to be counted on as 'climate savers'      (via sciencedaily.com)     Original source 

Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. The team found the amount potentially sequestered by the whales was too minimal to make significant impact on the trajectory of climate change.

The other side of the story: How evolution impacts the environment      (via sciencedaily.com)     Original source 

Researchers show that an evolutionary change in the length of lizards' legs can have a significant impact on vegetation growth and spider populations on small islands in the Bahamas. This is one of the first times, the researchers say, that such dramatic evolution-to-environment effects have been documented in a natural setting.

Finally solved! The great mystery of quantized vortex motion      (via sciencedaily.com)     Original source 

Scientists investigated numerically the interaction between a quantized vortex and a normal-fluid. Based on the experimental results, researchers decided the most consistent of several theoretical models. They found that a model that accounts for changes in the normal-fluid and incorporates more theoretically accurate mutual friction is the most compatible with the experimental results.

The 'breath' between atoms -- a new building block for quantum technology      (via sciencedaily.com)     Original source 

Researchers have discovered they can detect atomic 'breathing,' or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic 'breath' could help researchers encode and transmit quantum information.

Forest birds with short, round wings more sensitive to habitat fragmentation      (via sciencedaily.com)     Original source 

Tropical forest birds, which tend to have wings that are short and round relative to their body length and shape, are more sensitive to habitat fragmentation than the long-, slender-winged species common in temperate forests.

Study identifies boat strikes as a growing cause of manatee deaths in Belize      (via sciencedaily.com)     Original source 

The endangered Antillean manatee faces a growing threat from boat strikes in Belize, according to a new study that raises concerns about the survival of what had been considered a relatively healthy population. Belize hosts a population of around 1,000 manatees. With the growth of tourism in recent decades, however, Belize has seen a substantial increase in boat traffic, making boat strikes an increasingly important cause of manatee deaths and injuries.
