Published Overcoming barriers to heat pump adoption in cold climates and avoiding the 'energy poverty trap'
(via sciencedaily.com)
Original source 
Converting home heating systems from natural gas furnaces to electric heat pumps is seen as a way to address climate change by reducing greenhouse gas emissions.
Published Mussels downstream of wastewater treatment plant contain radium, study reports
(via sciencedaily.com)
Original source 
Burrowed into streambeds and rarely moving for their decades-long lifespans, freshwater mussels are biomonitors, meaning they indicate how clean their environment is, according to researchers. As the bivalves feed on organic matter and filter the water around them, their inner tissues and hard shells begin to reflect whatever is in their environment -- including radioactive particles.
Published Researchers discover 'trojan horse' virus hiding in human parasite
(via sciencedaily.com)
Original source 
An international team has found a new RNA virus that they believe is hitching a ride with a common human parasite. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis disease.
Published Fjords are effective carbon traps regardless of oxygen levels
(via sciencedaily.com)
Original source 
The fjords on Sweden's west coast act as effective carbon traps regardless of whether the bottom water is oxygen-rich or not.
Published Trout in mine-polluted rivers are genetically 'isolated'
(via sciencedaily.com)
Original source 
Trout living in rivers polluted by metal from old mines across the British Isles are genetically 'isolated' from other trout, new research shows.
Published New coral disease forecasting system
(via sciencedaily.com)
Original source 
Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.
Published Novel mobile air monitoring technology yields greater insight into post-disaster pollution levels
(via sciencedaily.com)
Original source 
A team has found that high resolution mass spectrometry could be a valuable tool for identifying and assessing air-borne contaminants produced by natural and human-made disasters.
Published People are altering decomposition rates in waterways
(via sciencedaily.com)
Original source 
Humans may be accelerating the rate at which organic matter decomposes in rivers and streams on a global scale, according to a new study. That could pose a threat to biodiversity in waterways around the world and increase the amount of carbon in Earth's atmosphere, potentially exacerbating climate change. The study is the first to combine a global experiment and predictive modeling to illustrate how human impacts to waterways may contribute to the global climate crisis.
Published New, modified CRISPR protein can fit inside virus used for gene therapy
(via sciencedaily.com)
Original source 
Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells.
Published Historic iceberg surges offer insights on modern climate change
(via sciencedaily.com)
Original source 
A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater runoff.
Published Every drop counts: New algorithm tracks Texas daily reservoir evaporation rates
(via sciencedaily.com)
Original source 
Researchers have developed a more accurate method for tracking reservoir evaporation rates that will improve water planning and management.
Published New method makes hydrogen from solar power and agricultural waste
(via sciencedaily.com)
Original source 
Engineers have helped design a new method to make hydrogen gas from water using only solar power and agricultural waste such as manure or husks. The method reduces the energy needed to extract hydrogen from water by 600%, creating new opportunities for sustainable, climate-friendly chemical production.
Published Controlling ion transport for a blue energy future
(via sciencedaily.com)
Original source 
Researchers probed the transit of cations across a nanopore membrane for the generation of osmotic energy. The team controlled the passage of cations across the membrane using a voltage applied to a gate electrode. This control allowed the cation-selective transport to be tuned from essentially zero to complete cation selectivity. The findings are expected to support the application of blue energy solutions for sustainable energy alternatives worldwide.
Published Local bright spot among melting glaciers: 2000 km of Antarctic ice-covered coastline has been stable for 85 years
(via sciencedaily.com)
Original source 
A whaler's forgotten aerial photos from 1937 have given researchers the most detailed picture of the ice evolution in East Antarctica to date. The results show that the ice has remained stable and even grown slightly over almost a century, though scientists observe early signs of weakening. The research offers new insights that enhance predictions of ice changes and sea level rise.
Published High groundwater depletion risk in South Korea in 2080s
(via sciencedaily.com)
Original source 
Team utilizes advanced statistical techniques to project the future groundwater depletion risk.
Published Safeguarding urban infrastructure from subsidence and liquefaction risks
(via sciencedaily.com)
Original source 
During an earthquake, soil can weaken through subsidence and liquefaction. These processes can cause buildings to collapse as the soil becomes unable to support their weight. Researchers have now developed a model that predicts soil-bearing strength and thickness to identify stable construction sites and reduce structural risks. Additionally, the model can also predict other soil conditions in real-time and function as an early-warning system to identify potential hazards.
Published Indian Ocean surface temperature could help anticipate dengue outbreaks
(via sciencedaily.com)
Original source 
Although dengue outbreaks cannot be prevented, it is possible to anticipate them. Scientists have recently identified a global climate indicator that may help improve predictions about the magnitude of dengue outbreaks several months in advance. This indicator, which can be used for any world region, is based on temperature fluctuations at the surface of the Indian Ocean. Obtaining reliable long-term predictions could facilitate efforts to tackle this infection, which has been on the rise for several decades and threatens half of the world's population.
Published Antibiotic pollution disrupts the gut microbiome and blocks memory in aquatic snails
(via sciencedaily.com)
Original source 
Antibiotics prevent snails from forming new memories by disrupting their gut microbiome -- the community of beneficial bacteria found in their guts.
Published Researchers expose new symbiosis origin theories, identify experimental systems for plant life
(via sciencedaily.com)
Original source 
Research work on symbiosis -- a mutually beneficial relationship between living organisms -- is pushing back against the newer theory of a 'single-origin' of root nodule symbiosis (RNS) -- that all symbiosis between plant root nodules and nitrogen-fixing bacteria stems from one point--instead suggesting a 'multiple-origin' theory of sybiosis which opens a better understanding for genetically engineering crops.
Published A drying Salton Sea pollutes neighboring communities
(via sciencedaily.com)
Original source 
Dust particles from the Salton Sea's exposed lakebed increased air pollution in local communities, found a new study. The pollution coincides with reduced flows into the lake and diversions to San Diego.
