Published Lemur's lament: When one vulnerable species stalks another
(via sciencedaily.com) Original source What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.
Published Energy scientists unravel the mystery of gold's glow
(via sciencedaily.com) Original source EPFL researchers have developed the first comprehensive model of the quantum-mechanical effects behind photoluminescence in thin gold films; a discovery that could drive the development of solar fuels and batteries.
Published Marine microbial populations: Potential sensors of the global change in the ocean
(via sciencedaily.com) Original source Animal and plant populations have been extensively studied, which has helped to understand ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations due to the impossibility of isolating, culturing and analyzing the genetic content of the different species and their individuals in the laboratory. Therefore, although it is known that populations of microorganisms include a great diversity, this remains largely uncharacterized.
Published Atom-by-atom: Imaging structural transformations in 2D materials
(via sciencedaily.com) Original source Silicon-based electronics are approaching their physical limitations and new materials are needed to keep up with current technological demands. Two-dimensional (2D) materials have a rich array of properties, including superconductivity and magnetism, and are promising candidates for use in electronic systems, such as transistors. However, precisely controlling the properties of these materials is extraordinarily difficult.
Published Understanding climate warming impacts on carbon release from the tundra
(via sciencedaily.com) Original source The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon sinks into a carbon source, exacerbating the effects of climate change.
Published Unique field study shows how climate change affects fire-impacted forests
(via sciencedaily.com) Original source During the unusually dry year of 2018, Sweden was hit by numerous forest fires. A research team has investigated how climate change affects recently burnt boreal forests and their ability to absorb carbon dioxide.
Published Two-dimensional nanomaterial sets record for expert-defying, counter-intuitive expansion
(via sciencedaily.com) Original source Engineers have developed a record-setting nanomaterial which when stretched in one direction, expands perpendicular to the applied force.
Published Coral reef microbes point to new way to assess ecosystem health
(via sciencedaily.com) Original source A new study shows that ocean acidification is changing the mix of microbes in coral reef systems, which can be used to assess ecosystem health.
Published Photonic computation with sound waves
(via sciencedaily.com) Original source Optical neural networks may provide the high-speed and large-capacity solution necessary to tackle challenging computing tasks. However, tapping their full potential will require further advances. One challenge is the reconfigurability of optical neural networks. A research team has now succeeded in laying the foundation for new reconfigurable neuromorphic building blocks by adding a new dimension to photonic machine learning: sound waves. The researchers use light to create temporary acoustic waves in an optical fiber. The sound waves generated in this way can for instance enable a recurrent functionality in a telecom optical fiber, which is essential to interpreting contextual information such as language.
Published Creating an island paradise in a fusion reactor
(via sciencedaily.com) Original source In their ongoing quest to develop a range of methods for managing plasma so it can be used to generate electricity in a process known as fusion, researchers have shown how two old methods can be combined to provide greater flexibility.
Published Crucial connection for 'quantum internet' made for the first time
(via sciencedaily.com) Original source Researchers have produced, stored, and retrieved quantum information for the first time, a critical step in quantum networking.
Published Tropical forests can't recover naturally without fruit-eating birds
(via sciencedaily.com) Original source Natural forest regeneration is hailed as a cost-effective way to restore biodiversity and sequester carbon. However, the fragmentation of tropical forests has restricted the movement of large birds limiting their capacity to disperse seeds and restore healthy forests.
Published Quantum precision: A new kind of resistor
(via sciencedaily.com) Original source Researchers have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall effect.
Published Where have all the right whales gone?
(via sciencedaily.com) Original source Marine researchers have mapped the density of one of the most endangered large whale species worldwide, the North Atlantic right whale, using new data to help avoid right whales' harmful exposure to commercial fisheries and vessel strikes. The resulting maps, spanning 20 years of whale observations, are publicly available to inform risk assessments, estimations of whale harm/disturbance, marine spatial planning, and industry regulations to mitigate risk to right whales.
Published 'Surprising' hidden activity of semiconductor material spotted by researchers
(via sciencedaily.com) Original source New research suggests that materials commonly overlooked in computer chip design actually play an important role in information processing, a discovery which could lead to faster and more efficient electronics. Using advanced imaging techniques, an international team found that the material that a semiconductor chip device is built on, called the substrate, responds to changes in electricity much like the semiconductor on top of it.
Published With inspiration from 'Tetris,' researchers develop a better radiation detector
(via sciencedaily.com) Original source A new detector system based on the game 'Tetris' could enable inexpensive, accurate radiation detectors for monitoring nuclear sites.
Published Ants in Colorado are on the move due to climate change
(via sciencedaily.com) Original source Ant species living in Boulder's foothills have shifted their habitat over the last six decades, potentially affecting local ecosystems, suggests a new study.
Published Quantum breakthrough when light makes materials magnetic
(via sciencedaily.com) Original source The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories. Now, researchers have succeeded in demonstrating for the very first time how laser light can induce quantum behavior at room temperature -- and make non-magnetic materials magnetic. The breakthrough is expected to pave the way for faster and more energy-efficient computers, information transfer and data storage.
