Published Bartering light for light: Scientists discover new system to control the chaotic behavior of light
(via sciencedaily.com) Original source Researchers describe a new platform for controlling the chaotic behavior of light by tailoring its scattering patterns using light itself.
Published Where is a sea star's head? Maybe just about everywhere
(via sciencedaily.com) Original source A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry.
Published Dam removals, restoration project on Klamath River expected to help salmon, researchers conclude
(via sciencedaily.com) Original source The world's largest dam removal and restoration project currently underway on the Klamath River in Oregon and California will aid salmon populations that have been devastated by disease and other factors. However, it will not fully alleviate challenges faced by the species, a team of researchers conclude.
Published Reverse engineering Jackson Pollock
(via sciencedaily.com) Original source Researchers combined physics and machine learning to develop a new 3D-printing technique that can quickly create complex physical patterns -- including replicating a segment of a Pollock painting -- by leveraging the same natural fluid instability that Pollock used in his work.
Published Shifting nesting timing not enough to prevent fewer sea turtle hatchlings
(via sciencedaily.com) Original source New research shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production.
Published Researchers observe wolves hunting and killing sea otters and harbor seals on Alaska's Katmai coast
(via sciencedaily.com) Original source Firsthand observations of a wolf hunting and killing a harbor seal and a group of wolves hunting and consuming a sea otter on Alaska's Katmai coast have led scientists to reconsider assumptions about wolf hunting behavior.
Published Late not great -- imperfect timekeeping places significant limit on quantum computers
(via sciencedaily.com) Original source Quantum physicists show that imperfect timekeeping places a fundamental limit to quantum computers and their applications. The team claims that even tiny timing errors add up to place a significant impact on any large-scale algorithm, posing another problem that must eventually be solved if quantum computers are to fulfill the lofty aspirations that society has for them.
Published Low-income countries could lose 30% of nutrients like protein and omega-3 from seafood due to climate change
(via sciencedaily.com) Original source The nutrients available from seafood could drop by 30 per cent for low-income countries by the end of the century due to climate change, suggests new research. That's in a high carbon emissions and low mitigation scenario, according to the study. This could be reduced to a roughly 10 per cent decline if the world were to meet the Paris Agreement targets of limiting global warming to 1.5 to 2 degrees Celsius -- which recent reports have shown we're not on track to achieve.
Published New species of mosasaur named for Norse sea serpent
(via sciencedaily.com) Original source Scientists have discovered a new species of mosasaur, large, carnivorous aquatic lizards that lived during the late Cretaceous. With 'transitional' traits that place it between two well-known mosasaurs, the new species is named after a sea serpent in Norse mythology, Jormungandr, and the small North Dakota city Walhalla near to where the fossil was found.
Published Wireless device makes magnetism appear in non-magnetic materials
(via sciencedaily.com) Original source Researchers have succeeded in bringing wireless technology to the fundamental level of magnetic devices. The emergence and control of magnetic properties in cobalt nitride layers (initially non-magnetic) by voltage, without connecting the sample to electrical wiring, represents a paradigm shift that can facilitate the creation of magnetic nanorobots for biomedicine and computing systems where basic information management processes do not require wiring.
Published Increasing risk of invasive species colonization on marine debris
(via sciencedaily.com) Original source A groundbreaking scientific study conducted along the Southeast coast of India has unearthed a pressing environmental concern -- the increasing risk of invasive species colonization on marine debris. The research delves into the critical interplay between plastic pollution and the introduction of non-indigenous organisms into Indian waters.
Published Controlling waves in magnets with superconductors for the first time
(via sciencedaily.com) Original source Quantum physicists have shown that it's possible to control and manipulate spin waves on a chip using superconductors for the first time. These tiny waves in magnets may offer an alternative to electronics in the future, interesting for energy-efficient information technology or connecting pieces in a quantum computer, for example. The breakthrough primarily gives physicists new insight into the interaction between magnets and superconductors.
Published Breakthrough synthesis method improves solar cell stability
(via sciencedaily.com) Original source A new process yields 2D halide perovskite crystal layers of ideal thickness and purity through dynamic control of the crystallization process -- a key step toward ensuring device stability for optoelectronics and photovoltaics.
Published New research finds stress and strain changes metal electronic structure
(via sciencedaily.com) Original source New research shows that the electronic structure of metals can strongly affect their mechanical properties.
Published A superatomic semiconductor sets a speed record
(via sciencedaily.com) Original source The search is on for better semiconductors. A team of chemists describes the fastest and most efficient semiconductor yet: a superatomic material called Re6Se8Cl2.
Published Conduction electrons drive giant, nonlinear elastic response in Sr2RuO4
(via sciencedaily.com) Original source The hardness of a material normally is set by the strength of chemical bonds between electrons of neighboring atoms, not by freely flowing conduction electrons. Now a team of scientists has shown that current-carrying electrons can make the lattice much softer than usual in the material Sr2RuO4.
Published Major milestone achieved in new quantum computing architecture
(via sciencedaily.com) Original source Researchers report a significant advance in quantum computing. They have prolonged the coherence time of their single-electron qubit to an impressive 0.1 milliseconds, nearly a thousand-fold improvement.
Published Endangered whales live in area earmarked for gas exploration
(via sciencedaily.com) Original source Endangered whales and dolphins live year-round in an area of the Mediterranean earmarked for oil and gas exploration, new research shows.
Published 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.
Published 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.
