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.
Published Tiny spirits roam the corals of Japan -- two new pygmy squids discovered
(via sciencedaily.com) Original source Named after Japanese folklore, two cephalopod species have been discovered in the coastal waters of the Okinawa Islands.
Published 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.
Published 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.
Published 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.
Published Unearthing the ecological impacts of cicada emergences on North American forests
(via sciencedaily.com) Original source New research unveils the cascading effects of periodical cicada emergence events on forest ecosystems ahead of an historic convergence of broods set to emerge spring of 2024.
Published Heat waves harm bird reproduction on agricultural lands
(via sciencedaily.com) Original source The effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home. A new study found that extreme high temperatures significantly diminish bird reproductive success in agricultural landscapes.
Published 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.
Published Electrical control of quantum phenomenon could improve future electronic devices
(via sciencedaily.com) Original source A new electrical method to conveniently change the direction of electron flow in some quantum materials could have implications for the development of next-generation electronic devices and quantum computers. A team of researchers has developed and demonstrated the method in materials that exhibit the quantum anomalous Hall (QAH) effect -- a phenomenon in which the flow of electrons along the edge of a material does not lose energy.
Published Yeast speeds discovery of medicinal compounds in plants
(via sciencedaily.com) Original source Researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.
Published Physicists create new form of antenna for radio waves
(via sciencedaily.com) Original source Physicists have used a small glass bulb containing an atomic vapor to demonstrate a new form of antenna for radio waves. The bulb was 'wired up' with laser beams and could therefore be placed far from any receiver electronics.
Published Orchid without bumblebee on island finds wasp, loses self
(via sciencedaily.com) Original source Because the bumblebee that an orchid relies on for pollination does not exist on a remote island, the plant gets pollinated by an island wasp. Researchers found that this came at the cost of being hybridized with another orchid species adapted to being pollinated by the wasp. The finding showcases how plants in ecological relationships adapt to changing circumstances.
Published Critical step made for managing brushtail possums
(via sciencedaily.com) Original source Researchers say mapping the genetic code of the brushtail possum will benefit those working to both conserve and control the animal.
Published How to help save plants from extinction
(via sciencedaily.com) Original source Now is the time to identify the conditions that cause plants to die. Doing so will allow us to better protect plants by choosing conservation targets more strategically, botanists argue.
Published Study reveals our European ancestors ate seaweed and freshwater plants
(via sciencedaily.com) Original source Researchers say they have found 'definitive' archaeological evidence that seaweeds and other local freshwater plants were eaten in the mesolithic, through the Neolithic transition to farming and into the Early Middle Ages, suggesting that these resources, now rarely eaten in Europe, only became marginal much more recently.
Published AI models identify biodiversity from animal sounds in tropical rainforests
(via sciencedaily.com) Original source Animal sounds are a very good indicator of biodiversity in tropical reforestation areas. Researchers demonstrate this by using sound recordings and AI models.
Published Simulations of 'backwards time travel' can improve scientific experiments
(via sciencedaily.com) Original source Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics.
Published Endemic malaria found in high, dry northwestern Kenya
(via sciencedaily.com) Original source Turkana County in northwestern Kenya was thought to be too dry for the mosquitoes that harbor malaria-causing parasites. But that assumption may have been wrong, according to a new study by malaria researchers. The arrival of a new mosquito and a more pernicious species of parasite could reverse the progress East Africa has made in controlling malaria.
Published Bouldering in south-central Madagascar: A new 'rock-climbing' gecko species of the genus Paroedura
(via sciencedaily.com) Original source A new Paroedura gecko species was reported at two small forest sites, Anja Reserve and Tsaranoro Valley forest, in the south-central plateau of Madagascar. Thanks to the recently collected samples, it was described and named after its preferred habitat, the boulders surrounded by the last remaining forests at these sites. Its conservation status was evaluated as Critically Endangered given its tiny distributional range.
Published Ionic crystal generates molecular ions upon positron irradiation, finds new study
(via sciencedaily.com) Original source The interaction between solid matter and positron (the antiparticle of electron) has provided important insights across a variety of disciplines, including atomic physics, materials science, elementary particle physics, and medicine. However, the experimental generation of positronic compounds by bombardment of positrons onto surfaces has proved challenging. In a new study, researchers detect molecular ion desorption from the surface of an ionic crystal when bombarded with positrons and propose a model based on positronic compound generation to explain their results.
