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 Plant sensors could act as an early warning system for farmers
(via sciencedaily.com)
Original source 
Using a pair of sensors made from carbon nanotubes, researchers discovered signals that help plants respond to stresses such as heat, light, or attack from insects or bacteria. Farmers could use these sensors to monitor threats to their crops, allowing them to intervene before the crops are lost.
Published From defects to order: Spontaneously emerging crystal arrangements in perovskite halides
(via sciencedaily.com)
Original source 
A new hybrid layered perovskite featuring elusive spontaneous defect ordering has been found, report scientists. By introducing specific concentrations of thiocyanate ions into FAPbI3 (FA = formamidinium), they observed that ordered columnar defects appeared in the stacked crystalline layers, taking up one-third of the lattice space. These findings could pave the way to an innovative strategy for adjusting the properties of hybrid perovskites, leading to practical advances in optoelectronics and energy generation.
Published How soil microbes survive in harsh desert environments
(via sciencedaily.com)
Original source 
Prolonged droughts followed by sudden bursts of rainfall -- how do desert soil bacteria manage to survive such harsh conditions? This long-debated question has now been answered by microbiologists. The study reveals that desert soil bacteria are highly adapted to survive the rapid environmental changes experienced with each rainfall event.
Published Paradox of extreme cold events in a warming world
(via sciencedaily.com)
Original source 
The Warm Arctic-Cold Continent (WACC) phenomenon is the puzzling combination of Arctic warming and extreme coldness in specific mid-latitude regions. However, the progression of WACC events remains unclear amidst global warming. Scientists have now predicted a sharp decline in the WACC phenomenon post-2030s, affecting extreme weather events. These findings offer critical insights for communities, scientists, and policymakers to refine climate models and strategies and battle climate change.
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 Researchers shine light on rapid changes in Arctic and boreal ecosystems
(via sciencedaily.com)
Original source 
Arctic and boreal latitudes are warming faster than any other region on Earth.
Published Trash to treasure -- researchers turn metal waste into catalyst for hydrogen
(via sciencedaily.com)
Original source 
Scientists have found a way to transform metal waste into a highly efficient catalyst to make hydrogen from water, a discovery that could make hydrogen production more sustainable.
Published CO2 worsens wildfires by helping plants grow
(via sciencedaily.com)
Original source 
By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a new study.
Published Huge database gives insight into salmon patterns at sea
(via sciencedaily.com)
Original source 
A massive new analysis of high seas salmon surveys is enhancing the understanding of salmon ecology, adding details about where various species congregate in the North Pacific Ocean and their different temperature tolerances. The project integrates numerous international salmon studies from the North Pacific dating back to the 1950s.
Published Researchers advance pigment chemistry with moon-inspired reddish magentas
(via sciencedaily.com)
Original source 
A researcher who made color history in 2009 with a vivid blue pigment has developed durable, reddish magentas inspired by lunar mineralogy and ancient Egyptian chemistry.
Published How blue-green algae manipulate microorganisms
(via sciencedaily.com)
Original source 
A research team discovers previously unknown gene that indirectly promotes photosynthesis Protein regulator NirP1 influences the coordination of the nitrogen and carbohydrate metabolism 'Such protein regulators could in future be deployed in 'green' and 'blue' biotechnology for targeted control of the metabolism,' says geneticist.
Published Switch to green wastewater infrastructure could reduce emissions and provide huge savings according to new research
(via sciencedaily.com)
Original source 
Researchers have shown that a transition to green wastewater-treatment approaches in the U.S. that leverages the potential of carbon-financing could save a staggering $15.6 billion and just under 30 million tons of CO2-equivalent emissions over 40 years.
Published Researchers resolve old mystery of how phages disarm pathogenic bacteria
(via sciencedaily.com)
Original source 
Bacterial infections pose significant challenges to agriculture and medicine, especially as cases of antibiotic-resistant bacteria continue to rise. In response, scientists are elucidating the ways that bacteria-infecting viruses disarm these pathogens and ushering in the possibility of novel treatment methods.
Published Researchers study effects of solvation and ion valency on metallopolymers
(via sciencedaily.com)
Original source 
Researchers analyzed the effects of solvation and ion valency on metallopolymers, with implications for critical materials recovery and recycling, and environmental remediation.
Published Innovative antiviral defense with new CRISPR tool
(via sciencedaily.com)
Original source 
The rise of RNA viruses like SARS-CoV-2 highlights the need for new ways to fight them. RNA-targeting tools like CRISPR/Cas13 are powerful but inefficient in the cytoplasm of cells, where many RNA viruses replicate. Scientists have devised a solution: Cas13d-NCS. This new molecular tool allows CRISPR RNA molecules that are located within the nucleus of a cell to move to the cytoplasm, making it highly effective at neutralizing RNA viruses. This advancement opens doors for precision medicine and proactive viral defense strategies.
Published A new spin on organic shampoo makes it sudsier, longer lasting
(via sciencedaily.com)
Original source 
While there's no regulation in the U.S. for what's in organic shampoos, they tend to contain ingredients perceived as safe or environmentally friendly. However, these 'clean' shampoos separate and spoil faster than those made with synthetic stabilizers and preservatives. Now, researchers demonstrate that a simple process -- spinning organic shampoo at high speeds -- improved the final products' shelf lives and ability to clean hair.
Published Nanoscale movies shed light on one barrier to a clean energy future
(via sciencedaily.com)
Original source 
New research is shedding light on one barrier to a clean energy future: corrosion. Using nanoscale imaging techniques, researchers have captured high-resolution videos of tiny crystals of ruthenium dioxide -- a key ingredient used to produce clean-burning hydrogen -- as they are eaten away by their acidic environment. The research could pave the way to more durable catalysts and dramatically extend the lifetime of devices needed to turn hydrogen green.
Published Oxidant pollutant ozone removes mating barriers between fly species
(via sciencedaily.com)
Original source 
Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to ozone and produce hybrid offspring. Since most of these offspring are unable to reproduce, the results could provide another explanation for the global decline of insects.
