Published Large herbivores keep invasive plants at bay
(via sciencedaily.com) Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.
Published Atomically-precise quantum antidots via vacancy self-assembly
(via sciencedaily.com) Scientists demonstrated a conceptual breakthrough by fabricating atomically precise quantum antidots using self-assembled single vacancies in a two-dimensional transition metal dichalcogenide.
Published Farms that create habitat key to food security and biodiversity
(via sciencedaily.com) Diversified farming is an important complement to forest protections for reversing tropical biodiversity declines.
Published Most species are rare, but not very rare
(via sciencedaily.com) Original source More than 100 years of observations in nature have revealed a universal pattern of species abundances: Most species are rare but not very rare, and only a few species are very common. These so-called global species abundance distributions have become fully unveiled for some well-monitored species groups, such as birds. For other species groups, such as insects, however, the veil remains partially unlifted. A new study demonstrates how important biodiversity monitoring is for detecting species abundances on planet Earth and for understanding how they change.
Published Peering into nanofluidic mysteries one photon at a time
(via sciencedaily.com) Original source Researchers have revealed an innovative approach to track individual molecule dynamics within nanofluidic structures, illuminating their response to molecules in ways never before possible.
Published A global observatory to monitor Earth's biodiversity
(via sciencedaily.com) Original source At a time of unparalleled rates of biodiversity loss, a new interconnected system to monitor biodiversity around the world is needed to guide action quickly enough to target conservation efforts to where they are most needed.
Published Researchers develop ultra-sensitive photoacoustic microscopy for wide biomedical application potential
(via sciencedaily.com) Optical-resolution photoacoustic microscopy is an up-and-coming biomedical imaging technique for studying a broad range of diseases, such as cancer, diabetes and stroke. But its insufficient sensitivity has been a longstanding obstacle for its wider application. Recently, a research team developed a multi-spectral, super-low-dose photoacoustic microscopy system with a significant improvement in the system sensitivity limit, enabling new biomedical applications and clinical translation in the future.
Published Want to fight climate change? Don't poach gorillas (or elephants, hornbills, toucans, etc.)
(via sciencedaily.com) Original source A new article found that overhunting of gorillas, elephants, and other large fruit-eating seed-dispersers make tropical forests less able to store or sequester carbon.
Published Soils forming on the branches of trees are an overlooked forest habitat
(via sciencedaily.com) A study on 'canopy soils' on old trees in Costa Rica shows they are important habitats and carbon stores that cannot easily be replaced.
Published New quantum device generates single photons and encodes information
(via sciencedaily.com) A new approach to quantum light emitters generates a stream of circularly polarized single photons, or particles of light, that may be useful for a range of quantum information and communication applications. A team stacked two different, atomically thin materials to realize this chiral quantum light source.
Published Scientists invent micrometers-thin battery charged by saline solution that could power smart contact lenses
(via sciencedaily.com) Scientists have developed a flexible battery as thin as a human cornea, which stores electricity when it is immersed in saline solution, and which could one day power smart contact lenses.
Published DNA chips as storage media of the future: What challenges need to be overcome
(via sciencedaily.com) In the form of DNA, nature shows how data can be stored in a space-saving and long-term manner. Bioinformatics specialists are developing DNA chips for computer technology. Researchers show how a combination of molecular biology, nanotechnology, novel polymers, electronics and automation, coupled with systematic development, could make DNA data storage useful for everyday use possible in a few years.
Published National parks support wildlife inside and outside their borders
(via sciencedaily.com) Fresh research suggests that national parks enhance bird diversity inside their borders. Large parks also support higher diversity of both birds and mammals in nearby unprotected areas.
Published Deforestation limits nesting habitat for cavity-nesting birds
(via sciencedaily.com) A new study of cavity-nesting birds in Ecuador shows the influence of deforestation on their habitat and reproductive success. Nest boxes could help.
Published Researchers unearth a new process by which algae pass on nurtrients to their coral host
(via sciencedaily.com) Researchers have identified a new pathway by which sugar is released by symbiotic algae. This pathway involves the largely overlooked cell wall, showing that this structure not only protects the cell but plays an important role in symbiosis and carbon circulation in the ocean.
Published Biodiversity protects against invasions of non-native tree species
(via sciencedaily.com) Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.
Published Listening to nanoscale earthquakes
(via sciencedaily.com) A recent study presents an exciting new way to listen to 'the crackling' noise of atoms shifting at nanoscale when materials are deformed, providing potential improved methods for discontinuities in novel, new materials, such as those proposed for future domain-wall electronics. 'Crackling noise microscopy' presents a new opportunity for generating advanced knowledge about nanoscale features across a wide range of applications and material systems.
Published The trio -- nickel, palladium, and platinum -- for enhanced hydrogen evolution
(via sciencedaily.com) A research team enhanced hydrogen evolution catalyst through stepwise deposition.
Published Small urban greening projects can dramatically increase number of insect species in cities
(via sciencedaily.com) Original source By increasing the diversity of indigenous plants in urban areas, researchers have seen a seven times increase in the number of insect species in just three years, confirming the ecological benefits of urban greening projects.
Published Fire, disease threatening sanctuary plants for Australian wildlife
(via sciencedaily.com) Original source New research has revealed Australia's iconic grasstrees -- known as 'yaccas' -- play a critical role in protecting wildlife from deadly weather extremes, thereby ensuring their survival. But the grasses themselves are under threat due to back burning, clearing and disease.
