Published Mapping the future's sweet spot for clean energy and biodiversity
(via sciencedaily.com) Original source A new study of Joshua trees, kit foxes and solar energy developments highlights the need to consider climate-induced range shifts for species as we expand clean energy.
Published A better handle on the emissions budget for the Paris climate targets
(via sciencedaily.com) Original source Scientists have found a new way to calculate the total carbon emissions consistent with the Paris climate targets of 1.5 degrees Celsius and 2 degrees Celsius of global warming.
Published New study reveals insight into which animals are most vulnerable to extinction due to climate change
(via sciencedaily.com) Original source In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.
Published Rock weathering and climate: Low-relief mountain ranges are largest carbon sinks
(via sciencedaily.com) Original source For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'
Published Loss of nature costs more than previously estimated
(via sciencedaily.com) Original source Researchers propose that governments apply a new method for calculating the benefits that arise from conserving biodiversity and nature for future generations.
Published Earth's earliest forest revealed in Somerset fossils
(via sciencedaily.com) Original source The oldest fossilized forest known on Earth -- dating from 390 million years ago -- has been found in the high sandstone cliffs along the Devon and Somerset coast of South West England.
Published Airflow dynamics scrub classroom air
(via sciencedaily.com) Original source Accounting for airflow dynamics rather than just airflow volume helped researchers measure an 85% reduction in airborne pathogens inside a working classroom.
Published Microbes impact coral bleaching susceptibility
(via sciencedaily.com) Original source A new study provides insights into the role of microbes and their interaction as drivers of interspecific differences in coral thermal bleaching.
Published Understanding wind and water at the equator key to more accurate future climate projections
(via sciencedaily.com) Original source Getting climate models to mimic real-time observations when it comes to warming is critical -- small discrepancies can lead to misunderstandings about the rate of global warming as the climate changes. A new study that when modeling warming trends in the Pacific Ocean, there is still a missing piece to the modeling puzzle: the effect of wind on ocean currents in the equatorial Pacific.
Published Micro- and nanoplastics in the body are passed on during cell division
(via sciencedaily.com) Original source The gastrointestinal tract is already known to researchers as a major storage site for micro- and nanoplastic particles (MNPs) in the human body. A research consortium has now investigated the effects of the tiny plastic particles on cancer cells in the human gastrointestinal tract. The study showed that MNPs remain in the cell for much longer than previously assumed, as they are passed on to the newly formed cell during cell division. The first indications were also discovered that the plastic particles could promote the metastasis of tumors.
Published Viscose manufactured solely from recycled materials
(via sciencedaily.com) Original source At present, viscose textiles are made of biomass from the forest, and there is no such thing as fully recycled viscose. Researchers have now succeeded in making new viscose -- from worn-out cotton sheets.
Published The world's most prolific CO2-fixing enzyme is slowly getting better
(via sciencedaily.com) Original source New research has found that rubisco -- the enzyme that fuels all life on Earth -- is not stuck in an evolutionary rut after all. The largest analysis of rubisco ever has found that it is improving all the time -- just very, very slowly. These insights could potentially open up new routes to strengthen food security.
Published Marine algae implants could boost crop yields
(via sciencedaily.com) Original source Scientists have discovered the gene that enables marine algae to make a unique type of chlorophyll. They successfully implanted this gene in a land plant, paving the way for better crop yields on less land.
Published Global warming is affecting bats' hibernation
(via sciencedaily.com) Original source Global change is altering the physiology of the hibernation and behavior of bats, according to a study carried out over a twenty year period. Given the milder winters we are having, bats are accumulating less fat reserves in autumn, they shorten their hibernation periods and they leave their winter shelter sooner. These changes could alter the migration pattern of bats and the phenology of their seasonal displacements.
Published Breakthrough research enables high-density hydrogen storage for future energy systems
(via sciencedaily.com) Original source A research team has reported a groundbreaking development in efficient hydrogen storage.
Published Nanodevices can produce energy from evaporating tap or seawater
(via sciencedaily.com) Original source Researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential.
Published Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows
(via sciencedaily.com) Original source The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.
Published Sinking land increases risk for thousands of coastal residents by 2050
(via sciencedaily.com) Original source A new study provides a new comprehensive look at the potential for flooding in a combined 32 cities along the Atlantic, Pacific, and Gulf coasts. It predicts as many as 500,000 people will be affected by flooding alongside 1 in 35 privately owned properties within the next three decades, and it highlights the racial and socioeconomic demographics of those potentially affected.
Published Key advance toward removing common herbicide from groundwater
(via sciencedaily.com) Original source Chemists are closing in on a new tool for tackling the global problem of weedkiller-tainted groundwater.
Published Research explores the cooling effects of 'scuba-diving' in lizards
(via sciencedaily.com) Original source Anoles are the scuba-diving champions of the lizard world, able to stay underwater for more than 16 minutes. For animals whose body temperature depends on the environment, time spent in a cool running stream can have some tradeoffs, according to new research.
