Published Self-correcting quantum computers within reach?
(via sciencedaily.com) Original source Quantum computers promise to reach speeds and efficiencies impossible for even the fastest supercomputers of today. Yet the technology hasn't seen much scale-up and commercialization largely due to its inability to self-correct. Quantum computers, unlike classical ones, cannot correct errors by copying encoded data over and over. Scientists had to find another way. Now, a new paper illustrates a quantum computing platform's potential to solve the longstanding problem known as quantum error correction.
Published Exploring parameter shift for quantum fisher information
(via sciencedaily.com) Original source Scientists have developed a technique called 'Time-dependent Stochastic Parameter Shift' in the realm of quantum computing and quantum machine learning. This breakthrough method revolutionizes the estimation of gradients or derivatives of functions, a crucial step in many computational tasks.
Published Tens of thousands of endangered sharks and rays caught off Congo
(via sciencedaily.com) Original source Tens of thousands of endangered sharks and rays are caught by small-scale fisheries off the Republic of the Congo each year, new research shows.
Published Remains of artificial turf is an important source of pollution of the aquatic environment
(via sciencedaily.com) Original source Every year, around 1,200 and 1,400 artificial turf sports fields are installed in the European Union. These fields are made up of synthetic fibers, mainly plastics, that mimic the appearance of natural grass. Recently, scientists conducted a study that characterizes and quantifies the presence of artificial turf fibers in samples collected from surface waters of the Catalan coast and the Guadalquivir River. The findings indicate that artificial turfs can be an important source of pollution in the aquatic environment, accounting for up to 15% of the plastics larger than 5 mm in length that are found floating in the aquatic environment.
Published A new way to erase quantum computer errors
(via sciencedaily.com) Original source Researchers have demonstrated a type of quantum eraser. The physicists show that they can pinpoint and correct for mistakes in quantum computing systems known as 'erasure' errors.
Published Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats
(via sciencedaily.com) Original source Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.
Published Twisted science: New quantum ruler to explore exotic matter
(via sciencedaily.com) Original source Researchers have developed a 'quantum ruler' to measure and explore the strange properties of multilayered sheets of graphene, a form of carbon. The work may also lead to a new, miniaturized standard for electrical resistance that could calibrate electronic devices directly on the factory floor, eliminating the need to send them to an off-site standards laboratory.
Published Shining a light on tiny, solar-powered animals
(via sciencedaily.com) Original source Acoels have been found to host a wide diversity of symbiotic, photosynthetic microalgae.
Published Machine learning used to probe the building blocks of shapes
(via sciencedaily.com) Original source Applying machine learning to find the properties of atomic pieces of geometry shows how AI has the power to accelerate discoveries in maths.
Published Invertebrate biodiversity is improving in England's rivers, long-term trends show
(via sciencedaily.com) Original source Rivers across England have seen a significant improvement in river invertebrate biodiversity since 1989, shows a new study.
Published Carbon-capture tree plantations threaten tropical biodiversity for little gain, ecologists say
(via sciencedaily.com) Original source The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.
Published Improved mangrove conservation could yield cash, carbon, coastal benefits
(via sciencedaily.com) Original source A shift in the way we think about the benefits mangroves provide to coastal regions could yield significant economic and biodiversity gains and protect millions from flooding, research has revealed.
Published Examining the superconducting diode effect
(via sciencedaily.com) Original source Scientists have reviewed the superconducting diode effect, a quantum effect enabling dissipationless supercurrent to flow in only one direction. The SDE provides new functionalities for superconducting circuits and future ultra-low energy superconducting/hybrid devices, with potential for quantum technologies in both classical and quantum computing.
Published A turtle time capsule: DNA found in ancient shell
(via sciencedaily.com) Original source Paleontologists discover possible DNA remains in fossil turtle that lived 6 million years ago in Panama, where continents collide.
Published Plastic cloud: New study analyzes airborne microplastics in clouds
(via sciencedaily.com) Original source Plastic waste that accumulates on land eventually ends up in the ocean as microplastics. However, it is now speculated that microplastics are also present in the atmosphere, contained in clouds. In a new study, researchers analyzed cloud water samples from high-altitude mountains in Japan to ascertain the amount of microplastics in them. They also shed light on how these airborne particles influence cloud formation and their negative impact on the climate.
Published Powering the quantum revolution: Quantum engines on the horizon
(via sciencedaily.com) Original source Scientists unveil exciting possibilities for the development of highly efficient quantum devices.
Published Protecting lands slows biodiversity loss among vertebrates by five times
(via sciencedaily.com) Original source Protecting large swaths of Earth's land can help stem the tide of biodiversity loss -- especially when those protected areas are in less disturbed landscapes and in countries with effective national governance. A new study looked at how amphibians, reptiles, mammals and birds fared in protected versus unprotected areas worldwide. Vertebrate abundance decreased five times more slowly inside protected areas, offering much-needed support for the United Nations' '30 by 30' conservation initiative.
Published New qubit circuit enables quantum operations with higher accuracy
(via sciencedaily.com) Researchers have developed a novel superconducting qubit architecture that can perform operations between qubits with much higher accuracy than scientists have yet been able to achieve. This architecture, which utilizes a relatively new type of superconducting qubit called fluxonium, is scalable and could be used to someday build a large-scale quantum computer.
Published Ocean acidification makes ecologically important seaweed species fragile
(via sciencedaily.com) Original source Ocean acidification will likely almost triple by the end of the century -- a drastic environmental change that could impact important marine species like fleshy seaweeds, algae that grow vertically and promote biodiversity in more than a third of the world's coastline. To get a better idea of how seaweeds might fare in a rapidly acidifying ocean, a team of marine scientists subjected a common fleshy seaweed species to the acidification levels expected by the end of the century. They report that increased acidification impacted the seaweed's chemical balance, made both its structure and its tissues weaker, and reduced its overall chances of survival.
Published Greenwashing a threat to a 'nature positive' world
(via sciencedaily.com) Original source Researchers have identified the threat greenwashing poses to a 'nature positive' world, one where environmental decline halts and biodiversity outcomes improve.
