Published Mountain forests are being lost at an accelerating rate, putting biodiversity at risk
(via sciencedaily.com) More than 85% of the world's bird, mammal, and amphibian species live in mountains, particularly in forest habitats, but researchers report that these forests are disappearing at an accelerating rate. Globally, we have lost 78.1 million hectares (7.1%) of mountain forest since 2000 -- an area larger than the size of Texas. Much of the loss occurred in tropical biodiversity hotspots, putting increasing pressure on threatened species.
Published New study counts the environmental cost of managing Japanese knotweed
(via sciencedaily.com) New research has looked at the long-term environmental impact of different methods to control Japanese knotweed. Different ways of trying to control the invasive species have developed over the years but now, as sustainability becomes increasingly important, understanding the effect of these management methods is vital.This new study examines at the entire life cycle and long-term impacts of different management approaches.
Published How can we tackle the biggest challenges? Ask a plant
(via sciencedaily.com) Without plants, we'd have no air to breathe or food to eat, yet plant science lingers in the shadowy wings while other fields take center stage. With the goal of shining the spotlight on plants, a new study presents the field's top 100 most pressing questions for research to address the greatest challenges facing humanity.
Published How fishermen benefit from reversing evolution of cod
(via sciencedaily.com) Intense fishing and over-exploitation have led to evolutionary changes in fish stocks like cod, reducing both their productivity and value on the market. These changes can be reversed by more sustainable and far-sighted fisheries management. A new study shows that reversal of evolutionary change would only slightly reduce the profit of fishing, but would help regain and conserve natural genetic diversity.
Published Breakthrough in the understanding of quantum turbulence
(via sciencedaily.com) Researchers have shown how energy disappears in quantum turbulence, paving the way for a better understanding of turbulence in scales ranging from the microscopic to the planetary. The team's findings demonstrate a new understanding of how wave-like motion transfers energy from macroscopic to microscopic length scales, and their results confirm a theoretical prediction about how the energy is dissipated at small scales. In the future, an improved understanding of turbulence beginning on the quantum level could allow for improved engineering in domains where the flow and behavior of fluids and gases like water and air is a key question. Understanding that in classical fluids will help scientists do things like improve the aerodynamics of vehicles, predict the weather with better accuracy, or control water flow in pipes. There is a huge number of potential real-world uses for understanding macroscopic turbulence.
Published Humans are altering the diet of Tasmanian devils, which may accelerate their decline
(via sciencedaily.com) New research shows how human-modified landscapes affect the diets of these marsupial scavengers.
Published Modelling superfast processes in organic solar cell material
(via sciencedaily.com) In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. Scientists have now calculated how this happens by combining molecular dynamics simulations with quantum calculations and have provided theoretical insights to interpret experimental data.
Published Genetics as conservation tool for endangered chimpanzees
(via sciencedaily.com) The western chimpanzees of Guinea are threatened by mining activities. Using a novel genetic approach, researchers have collected information on population size and community structure of the endangered species. These data provide an important baseline to assess the impact of mining.
Published Recovering tropical forests offset just one quarter of carbon emissions from new tropical deforestation and forest degradation
(via sciencedaily.com) A pioneering global study has found deforestation and forests lost or damaged due to human and environmental change, such as fire and logging, are fast outstripping current rates of forest regrowth.
Published Thousands of native plants are unphotographed, and citizen scientists can help fill the gaps
(via sciencedaily.com) New research finds almost 4000 Australian plant species have not been photographed before in the wild, which may lead to their extinction.
Published Swan populations grow 30 times faster in nature reserves
(via sciencedaily.com) Populations of whooper swans grow 30 times faster inside nature reserves, new research shows.
Published Magnetism fosters unusual electronic order in quantum material
(via sciencedaily.com) Physicists have published an array of experimental evidence showing that the ordered magnetic arrangement of electrons in crystals of iron-germanium plays an integral role in bringing about an ordered electronic arrangement called a charge density wave that the team discovered in the material last year.
Published Study shows how biodiversity of coral reefs around the world changes with depth
(via sciencedaily.com) Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.
Published Experiment unlocks bizarre properties of strange metals
(via sciencedaily.com) Physicists are learning more about the bizarre behavior of 'strange metals,' which operate outside the normal rules of electricity.
Published Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems
(via sciencedaily.com) An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.
Published Island-inhabiting giants, dwarfs more vulnerable to extinction
(via sciencedaily.com) Island-dwelling mammal species often expand or contract in size, becoming giant or dwarf versions of their mainland counterparts. A new Science study from a global team shows that those giants and dwarfs have faced extreme risk of extinction -- an existential threat exacerbated by the arrival of humans.
Published In the world's smallest ball game, scientists throw and catch single atoms using light
(via sciencedaily.com) Researchers show that individual atoms can be caught and thrown using light. This is the first time an atom has been released from a trap -- or thrown -- and then caught by another trap. This technology could be used in quantum computing applications.
Published Hitting nuclei with light may create fluid primordial matter
(via sciencedaily.com) A new analysis supports the idea that photons colliding with heavy ions create a fluid of 'strongly interacting' particles. The results indicate that photon-heavy ion collisions can create a strongly interacting fluid that responds to the initial collision geometry and that these collisions can form a quark-gluon plasma. These findings will help guide future experiments at the planned Electron-Ion Collider.
Published Researchers take a step towards turning interactions that normally ruin quantum information into a way of protecting it
(via sciencedaily.com) A new method for predicting the behavior of quantum devices provides a crucial tool for real-world applications of quantum technology.
Published Plant roots fuel tropical soil animal communities
(via sciencedaily.com) A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals. However, this recent study is the first to provide proof that resources derived from plant roots drive soil animal communities in the tropics.
