Published Study examines tree adaptability to climate change
(via sciencedaily.com) Original source Many trees could expand their ranges by more than 25 percent based on their potential temperature tolerances.
Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published How a plant app helps identify the consequences of climate change
(via sciencedaily.com) Original source A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
Published Mining rare earth metals from electronic waste
(via sciencedaily.com) Original source A small molecule that naturally serves as a binding site for metals in enzymes also proves useful for separating certain rare earth metals from each other. In a proof of concept, the process extracts europium directly from fluorescent powder in used energy-saving lamps in much higher quantities than existing methods. The researchers are now working on expanding their approach to other rare earth metals. They are in the process of founding a start-up to put the recycling of these raw materials into practice.
Published Study reveals environmental impact of artificial sweeteners
(via sciencedaily.com) Original source A recently published study demonstrates how sucralose affects the behavior of cyanobacteria -- an aquatic photosynthetic bacteria -- and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.
Published New extremely fast carbon storage technology
(via sciencedaily.com) Original source A new way to store carbon captured from the atmosphere works much faster than current methods without the harmful chemical accelerants they require.
Published Weaker ocean circulation could enhance carbon dioxide buildup in the atmosphere, study finds
(via sciencedaily.com) Original source Scientists may have to rethink the relationship between the ocean's circulation and its long-term capacity to store carbon, new research suggests. As the ocean gets weaker, it could release more carbon from the deep ocean into the atmosphere -- rather than less, as some have predicted.
Published Exploring the radiative effects of precipitation on Arctic amplification and energy budget
(via sciencedaily.com) Original source While, in theory, precipitation impacts the Earth's radiation budget, the radiative effects of precipitation (REP) are poorly understood and excluded from most climate models. Hence, a new study examined the role of REP in the global and regional energy budgets and hydrological cycles, finding that REP significantly contributes to temperature and precipitation variations at different geographical scales, especially in the Arctic warming. This highlights the relevance of including REP in climate modeling for improved accuracy.
Published Wastewater is a viable medium for growing lettuce in hydroponic systems
(via sciencedaily.com) Original source Urban agriculture has the potential to improve food security through local, efficient, and sustainable food production. Examples of urban food systems include hydroponics, where plants grow in a nutrient solution without soil, and aquaponics, which combines hydroponics with raising fish in tanks. A new study examines the use of aquaponics wastewater as a growth medium for lettuce in a hydroponic system. This practice can potentially create a circular ecosystem for organic waste recycling and food production.
Published Retreating glaciers: Fungi enhance carbon storage in young Arctic soils
(via sciencedaily.com) Original source Melting Arctic glaciers are in rapid recession, and microscopic pioneers colonize the new exposed landscapes. Researchers revealed that yeasts play an important role in soil formation in the Arctic.
Published Climate change drives tree species towards colder, wetter regions
(via sciencedaily.com) Original source Climate change is likely to drive tree species towards colder and wetter regions.
Published Mechanism of bio-inspired control of liquid flow
(via sciencedaily.com) Original source The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research implied that liquids can only be transported in fixed direction on species with specific liquid communication properties and cannot switch the transport direction. Recently, researchers have shown that an African plant controls water movement in a previously unknown way -- and this could inspire breakthroughs in a range of technologies in fluid dynamics and nature-inspired materials, including applications that require multistep and repeated reactions, such as microassays, medical diagnosis and solar desalination etc.
Published Exploring the chemical space of the exposome: How far have we gone?
(via sciencedaily.com) Original source Scientists have taken on the daunting challenge of mapping all the chemicals around us. They take inventory of the available science and conclude that currently a real pro-active chemical management is not feasible. To really get a grip on the vast and expanding chemical universe, they advocate the use of machine learning and AI, complementing existing strategies for detecting and identifying all molecules we are exposed to.
Published True scale of carbon impact from long-distance travel revealed
(via sciencedaily.com) Original source The reality of the climate impact of long-distance passenger travel has been revealed in new research.
Published Study illuminates cues algae use to 'listen' to their environment
(via sciencedaily.com) Original source New research shows how a small group of single-celled algae are able to use chemical cues to communicate stress information. Understanding this ability, once thought unique to plants, helps illuminate the complex evolutionary history of plants and algae.
Published Organic material from Mars reveals the likely origin of life's building blocks
(via sciencedaily.com) Original source Two samples from Mars together deliver clear evidence of the origin of Martian organic material. The study presents solid evidence for a prediction made over a decade ago that could be key to understanding how organic molecules, the foundation of life, were first formed here on Earth.
Published Shrinking glaciers: Microscopic fungi enhance soil carbon storage in new landscapes created by shrinking Arctic glaciers
(via sciencedaily.com) Original source Shrinking glaciers expose new land in the Arctic, creating unique ecosystems. Researchers studied how microbes colonize these barren landscapes. The study reveals a crucial role for specific fungal species in capturing and storing carbon in the newly formed soil. These findings suggest fungi are essential for future carbon storage in the Arctic as glaciers continue to recede.
Published Novel spectroscopy technique sheds light on NOx reduction
(via sciencedaily.com) Original source The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions have long existed between reaction models within the literature. Catalysis researchers used a technology called modulation excitation spectroscopy, or MES, to finally identify the correct pathway.
Published Choose where to plant energy crops wisely to minimise loss of biodiversity
(via sciencedaily.com) Original source In the fight to protect biodiversity and limit climate change, the world will reap what it sows.
