Published Researchers craft new way to make high-temperature superconductors -- with a twist
(via sciencedaily.com)
Original source 
An international team has developed a new method to make and manipulate a widely studied class of high-temperature superconductors. This technique should pave the way for the creation of unusual forms of superconductivity in previously unattainable materials.
Published Superfluids could share characteristic with common fluids
(via sciencedaily.com)
Original source 
Every fluid -- from Earth's atmosphere to blood pumping through the human body -- has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter. If the viscosity is higher, the fluid flows calmly, a state known as laminar. If the viscosity decreases, the fluid undergoes the transition from laminar to turbulent flow. The degree of laminar or turbulent flow is referred to as the Reynolds number, which is inversely proportional to the viscosity. However, this Reynolds similitude does not apply to quantum superfluids. A researcher has theorized a way to examine the Reynolds similitude in superfluids, which could demonstrate the existence of quantum viscosity in superfluids.
Published Asparagus and orchids are more similar than you think
(via sciencedaily.com)
Original source 
How is a beech leaf constructed? What determines the appearance of an asparagus? A new 'encyclopaedia' helps us learn more about the building blocks of plants. The encyclopaedia, probably the largest of its kind, could be used to improve targeted plant breeding efforts, to make them both more climate-resilient and more easily digestible.
Published Small yet mighty: Showcasing precision nanocluster formation with molecular traps
(via sciencedaily.com)
Original source 
Nanoclusters (NCs) of transition metals like cobalt or nickel have widespread applications in drug delivery and water purification, with smaller NCs exhibiting improved functionalities. Downsizing NCs is, however, usually challenging. Now, scientists have demonstrated functional NC formation with atomic-scale precision. They successfully grew cobalt NCs on flat copper surfaces using molecular arrays as traps. This breakthrough paves the way for advancements like single-atom catalysis and spintronics miniaturization.
Published Do tree-planting campaigns follow best practices for successful forest restoration?
(via sciencedaily.com)
Original source 
New research reviewed publicly available information for 99 different organizations that coordinate large-scale tree-planting programs around the globe to see if these organizations seemed to be applying best practices for successful reforestation.
Published Scientists pull off quantum coup
(via sciencedaily.com)
Original source 
Scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place.
Published Endangered seabird shows surprising individual flexibility to adapt to climate change
(via sciencedaily.com)
Original source 
New research finds that individual behavioural flexibility and not evolutionary selection is driving the northward shift of Balearic shearwaters. The findings were revealed through a decade-long study which tagged individual birds. The results indicate that individual animals may have greater behavioural flexibility to respond to climate change impacts than previously thought.
Published Back from the dead: Tropical tree fern repurposes its dead leaves
(via sciencedaily.com)
Original source 
Plant biologists report that a species of tree fern found only in Panama reanimates its own dead leaf fronds, converting them into root structures that feed the mother plant. The fern, Cyathea rojasiana, reconfigures these 'zombie leaves,' reversing the flow of water to draw nutrients back into the plant.
Published Scientists develop novel method to estimate biodiversity loss in Singapore over the past two centuries
(via sciencedaily.com)
Original source 
Scientists have employed novel statistical methods to reveal the extent of biodiversity loss in Singapore over the past two centuries. The study paints the most accurate picture to date of the ecological impact of deforestation and urban development in the tropical city-state. From a comprehensive dataset, the study estimated that Singapore has lost 37 per cent of its species.
Published Use it or lose it: How seagrasses conquered the sea
(via sciencedaily.com)
Original source 
Seagrasses provide the foundation of one of the most highly biodiverse, yet vulnerable, coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully submerged, marine flowering plants. Moving to such a radically different environment is a rare evolutionary event and definitely not easy. How did they do it? New reference quality genomes provide important clues with relevance to their conservation and biotechnological application.
Published Diverse forests are best at standing up to storms
(via sciencedaily.com)
Original source 
European forests with a greater diversity of tree species are more resilient to storms, according to new research.
Published Shining a light on the hidden properties of quantum materials
(via sciencedaily.com)
Original source 
Certain materials have desirable properties that are hidden and scientists can use light to uncover these properties. Researchers have used an advanced optical technique, based on terahertz time-domain spectroscopy, to learn more about a quantum material called Ta2NiSe5 (TNS).
Published Sparrows uniquely adapted to Bay Area marshes are losing their uniqueness
(via sciencedaily.com)
Original source 
How does loss of habitat affect the animals still living there? A genetic study of saltwater-adapted Savannah sparrows around the San Francisco Bay Area shows that the 90% loss of tidal marsh habitat has led to more interbreeding with freshwater-adapted Savannah sparrows, diminishing their genetic adaptation to saltwater, such as enlarged kidneys and larger beak. This could lessen their ability to live in a saltwater habitat.
Published Microplastics may be accumulating rapidly in endangered Galápagos penguins' food web
(via sciencedaily.com)
Original source 
Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.
Published Researchers add a 'twist' to classical material design
(via sciencedaily.com)
Original source 
Researchers grew a twisted multilayer crystal structure for the first time and measured the structure's key properties. The twisted structure could help researchers develop next-generation materials for solar cells, quantum computers, lasers and other devices.
Published The complexity of forests cannot be explained by simple mathematical rules, study finds
(via sciencedaily.com)
Original source 
The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.

(via sciencedaily.com)
Original source 
A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.
Published World's largest database of weeds lets scientists peer into the past, and future, of global agriculture
(via sciencedaily.com)
Original source 
A new database of weeds that can help scientists understand how traditional agricultural systems were managed throughout history, could also provide insights into how global trends like the climate crisis could affect the resilience of our modern day food systems.
Published Study offers rare long-term analysis of techniques for creating standing dead trees for wildlife habitat
(via sciencedaily.com)
Original source 
Ecologists have long known that standing dead trees, commonly referred to as snags, are an important habitat element for forest dwellers and act as a driver of biodiversity. They're so important that in some managed forests, snag creation is part of the conservation tool kit -- i.e., crews sometimes convert a percentage of live trees into dead ones through techniques ranging from sawing off their tops to wounding their trunks to injecting them with disease-causing fungi.
Published When conditions cool down, a bacterial prey species becomes the predator
(via sciencedaily.com)
Original source 
In a new study, two species of bacteria grown in a lab reversed their predator-prey relationship after one species was grown at a lower temperature.
