Published Flower power: The role of ants in forest regeneration
(via sciencedaily.com) Ants play a key role in forest regeneration, according to a new article.
Published Australia's rarest bird of prey disappearing at alarming rate
(via sciencedaily.com) Australia's rarest bird of prey -- the red goshawk -- is facing extinction, with Cape York Peninsula now the only place in Queensland known to support breeding populations.
Published New superacid converts harmful compounds into sustainable chemicals
(via sciencedaily.com) Researchers have succeeded in producing very special catalysts, known as 'Lewis superacids', which can be used to break strong chemical bonds and speed up reactions. The production of these substances has, until now, proven extremely difficult. The chemists' discovery enables non-biodegradable fluorinated hydrocarbons, similar to Teflon, and possibly even climate-damaging greenhouse gases, such as sulphur hexafluoride, to be converted back into sustainable chemicals.
Published Chaos on the nanometer scale
(via sciencedaily.com) Chaotic behavior is typically known from large systems: for example, from weather, from asteroids in space that are simultaneously attracted by several large celestial bodies, or from swinging pendulums that are coupled together. On the atomic scale, however, one does normally not encounter chaos -- other effects predominate. Now scientists have been able to detect clear indications of chaos on the nanometer scale -- in chemical reactions on tiny rhodium crystals.
Published New material may offer key to solving quantum computing issue
(via sciencedaily.com) A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers.
Published New method creates material that could create the next generation of solar cells
(via sciencedaily.com) Perovskites, a family of materials with unique electric properties, show promise for use in a variety fields, including next-generation solar cells. A team of scientists has now created a new process to fabricate large perovskite devices that is more cost- and time-effective than previously possible and that they said may accelerate future materials discovery.
Published Fastest laser camera films combustion in real time
(via sciencedaily.com) A research team has developed one of the world's fastest single-shot laser cameras, which is at least a thousand times faster than today's most modern equipment for combustion diagnostics. The discovery has enormous significance for studying the lightning-fast combustion of hydrocarbons.
Published New study reveals biodiversity loss drove ecological collapse after the 'Great Dying'
(via sciencedaily.com) By exploring the stability and collapse of marine ecosystems during the Permian-Triassic mass extinction, researchers gain insights into modern biodiversity crisis.
Published Research captures and separates important toxic air pollutant
(via sciencedaily.com) A series of new stable, porous materials that capture and separate benzene have been developed.
Published Electrodes grown in the brain -- paving the way for future therapies for neurological disorders
(via sciencedaily.com) The boundaries between biology and technology are becoming blurred. Researchers have now successfully grown electrodes in living tissue using the body's molecules as triggers. The result paves the way for the formation of fully integrated electronic circuits in living organisms.
Published Plastic upcycling to close the carbon cycle
(via sciencedaily.com) Original source A new method to convert waste plastic to fuel and raw materials promises to help close the carbon cycle at mild temperature and with high yield.
Published Urban ponds require attention to ensure biodiversity
(via sciencedaily.com) New research suggests aquatic plants can be utilized as a tool to enhance the co-existence between aquatic invertebrates and their fish predators in urban ponds.
Published Novel air filter captures wide variety of pollutants
(via sciencedaily.com) Original source An air filter made out of corn protein instead of petroleum products can concurrently capture small particulates as well as toxic chemicals like formaldehyde that current air filters can't. The research could lead to better air purifiers, particularly in regions of the world that suffer from very poor air quality. The more environmentally friendly air filter was able to simultaneously capture 99.5% of small particulate matter, similar to commercial HEPA filters, and 87% of formaldehyde, which is higher than specially designed air filters for those types of toxics.
Published Clever orchard design for more nuts
(via sciencedaily.com) To reduce biodiversity loss in agricultural landscapes, more sustainable and environmentally friendly agricultural practices are needed. A research team has investigated how ecosystem services such as pollination could be improved in macadamia plantations. The scientists showed that a certain design of plantations -- for instance, how the rows of trees are arranged, the varieties, and the integration of semi-natural habitats in and around the plantations -- can increase the pollination performance of bees.
Published A fifth of California's Sierra Nevada conifer forests are stranded in habitats that have grown too warm for them
(via sciencedaily.com) Researchers created maps showing where warmer weather has left trees in conditions that don't suit them, making them more prone to being replaced by other species. The findings could help inform long-term wildfire and ecosystem management in these 'zombie forests.'
Published Rising river temperatures hold important clues about climate and other human impacts
(via sciencedaily.com) An improved global understanding of river temperature could provide an important barometer for climate change and other human activities.
Published Climate 'spiral' threatens land carbon stores
(via sciencedaily.com) The world's forests are losing their ability to absorb carbon due to increasingly 'unstable' conditions caused by humans, a landmark study has found.
Published New research reveals 12 ways aquaculture can benefit the environment
(via sciencedaily.com) Aquaculture, or the farming of aquatic plants and animals, contributes to biodiversity and habitat loss in freshwater and marine ecosystems globally, but when used wisely, it can also be part of the solution, new research shows.
Published Researcher discovers threshold that triggers drought response in forests
(via sciencedaily.com) Missouri is home to an array of natural resources, with forests among the state's most valuable ecosystems. As warmer temperatures fueled by climate change affect ecosystems globally, forests are under stress to adapt to these changes and ensure their survival in a warmer world. Researchers now introduce the 'ecosystem wilting point' concept, which explains how whole forests respond to drought.
Published Detecting the impact of drought on plants with user-friendly and inexpensive techniques
(via sciencedaily.com) Climate change is aggravating the impact of droughts -- one of the factors that only affect plant physiology -- on all plant ecosystems worldwide. Although new tools have been developed to detect and assess drought stress in plants -- transcriptomic or metabolomic technologies, etc. -- they are still difficult to apply in natural ecosystems, especially in remote areas and developing countries.
