Physicists simulate interacting quasiparticles in ultracold quantum gas      (via sciencedaily.com)     Original source 

In physics, quasiparticles are used to describe complex processes in solids. In ultracold quantum gases, these quasiparticles can be reproduced and studied. Now scientists have been able to observe in experiments how Fermi polarons -- a special type of quasiparticle -- can interact with each other.

Using sound to test devices, control qubits      (via sciencedaily.com)     Original source 

Researchers have developed a system that uses atomic vacancies in silicon carbide to measure the stability and quality of acoustic resonators. What's more, these vacancies could also be used for acoustically-controlled quantum information processing, providing a new way to manipulate quantum states embedded in this commonly-used material.

Light, freshwater sticks to Greenland's east coast      (via sciencedaily.com)     Original source 

Meltwater that runs along the east coast of Greenland, hardly enters the open ocean before reaching the western side of the island.  In the changing climate, fresh water from Greenland and the Arctic could disrupt the circulation in the Atlantic Ocean.

How quantum light 'sees' quantum sound      (via sciencedaily.com)     Original source 

Researchers have proposed a new way of using quantum light to 'see' quantum sound. A new paper reveals the quantum-mechanical interplay between vibrations and particles of light, known as photons, in molecules. It is hoped that the discovery may help scientists better understand the interactions between light and matter on molecular scales. And it potentially paves the way for addressing fundamental questions about the importance of quantum effects in applications ranging from new quantum technologies to biological systems.

Unexpected behavior discovered in active particles      (via sciencedaily.com)     Original source 

Physicists have now shown that, depending on the extent to which the propulsion speed of active particles is dependent on their orientation, clusters in different shapes arise in many-particle systems. This might be a possible key to the realization of programmable matter.

Soft, living materials made with algae glow under stress      (via sciencedaily.com)     Original source 

Researchers have developed soft yet durable materials that glow in response to mechanical stress, such as compression, stretching or twisting. The materials derive their luminescence from single-celled algae known as dinoflagellates, which are embedded within the materials. The work was inspired by the bioluminescent waves caused by dinoflagellates during red tide events at San Diego's beaches.

Ancient sea monster remains reveal oldest mega-predatory pliosaur      (via sciencedaily.com)     Original source 

The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur -- a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs. The findings are rare and add new knowledge to the evolution of plesiosaurs.

Accelerating waves shed light on major problems in physics      (via sciencedaily.com)     Original source 

Researchers at Tampere University and the University of Eastern Finland have reached a milestone in a study where they derived a new kind of wave equation, which applies for accelerating waves. The novel formalism has turned out to be an unexpectedly fertile ground for examining wave mechanics, with direct connections between accelerating waves, general theory of relativity, as well as the arrow of time.

Researchers demonstrate a high-speed electrical readout method for graphene nanodevices      (via sciencedaily.com)     Original source 

Graphene is often referred to as a wonder material for its advantageous qualities. But its application in quantum computers, while promising, is stymied by the challenge of getting accurate measurements of quantum bit states with existing techniques. Now, researchers have developed design guidelines that enable radio-frequency reflectometry to achieve high-speed electrical readouts of graphene nanodevices.

Soil carried on sea freight loaded with dangerous pests and diseases, research finds      (via sciencedaily.com)     Original source 

While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.

DNA shows where Washington culvert replacements helped spawning salmon      (via sciencedaily.com)     Original source 

University and federal scientists used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Authors from the UW and NOAA are studying the use of environmental DNA, or eDNA, in future environmental impact reporting.

Scientists discover deepest known evidence of coral reef bleaching      (via sciencedaily.com)     Original source 

Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.

Waves of change: How sea-levels and climate altered the marine ecosystems at the South Pole 390-385 million years ago      (via sciencedaily.com)     Original source 

New research reveals a chain of environmental disasters. These took place in what is today's South Africa, during an ancient time period called the Early-Middle Devonian. The crises led to the extinction of a unique group of marine animals called the Malvinoxhosan biota.

A miniature magnetic resonance imager made of diamond      (via sciencedaily.com)     Original source 

The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research team has now developed diamond quantum sensors which can be used to improve resolution in magnetic imaging.
