Published Researchers examine cooling power plants with brackish groundwater
(via sciencedaily.com) Original source Nontraditional water sources can be deployed to help cope with climate-induced water risks and tackle the increasing water demand for decarbonization of fossil fuel-fired power plants, but that could increase the cost of electricity generation by 8 percent to 10 percent.
Published Researchers find new mechanism for sodium salt detoxification in plants
(via sciencedaily.com) Original source A team of researchers has found a mechanism in thale cress (Arabidopsis thaliana) which enables plants to provide protection against salt stress for their sensitive stem cells in the meristem at the root tip.
Published Researchers want to use 'biochar' to combat climate change
(via sciencedaily.com) Original source A new review of research suggests that the nature-based technology biochar -- a carbon-rich material -- could be an important tool to use in agriculture to help mitigate climate change.
Published Montreal protocol is delaying first ice-free Arctic summer
(via sciencedaily.com) Original source New research shows that the 1987 global treaty, designed to protect the ozone layer, has postponed the occurrence of the first ice-free Arctic by as much as 15 years.
Published How a drought affects trees depends on what's been holding them back
(via sciencedaily.com) Original source Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.
Published What you count is not necessarily what counts
(via sciencedaily.com) Original source Seawater is full of bacteria, hundreds of thousands live in every liter. But the sheer number of bacteria living in the water does not necessarily mean a lot. More important is how active they are and how quickly they duplicate.
Published Fine particulate matter catalyzes oxidative stress in the lungs
(via sciencedaily.com) Original source Study sheds new light on the adverse health effects of air pollution: hydrogen peroxide production of fine particles may not be as important as previously assumed. A new study reveals that the adverse health effects of fine particulate matter (PM2.5) are attributable to the conversion of peroxides into more reactive species such as the hydroxyl radical (OH) rather than the direct chemical production of hydrogen peroxide (H2O2) as previously thought.
Published Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world
(via sciencedaily.com) Original source Researchers found that the Hunga-Tonga eruption was associated with the formation of an equatorial plasma bubble in the ionosphere, a phenomenon associated with disruption of satellite-based communications. Their findings also suggest that a long-held atmospheric model should be revised.
Published Earlier snowpack melt in Western US could bring summer water scarcity
(via sciencedaily.com) Original source Mountain snowpack, typically seen as the water tower of the Western United States and Canada, is in decline, according to a new study. Researchers created the Snow Storage Index to assess snow water storage from 1950-2013 and found that storage has significantly declined in more than 25% of the Mountain West, in part because more snow is melting during winter and spring.
Published Microorganisms' climate adaptation can slow down global warming
(via sciencedaily.com) Original source A new study shows that the ability of microorganisms to adapt to climate warming will slow down global warming by storing carbon in soil.
Published Communities should reconsider walking away from curbside recycling, study shows
(via sciencedaily.com) Original source Researchers took a deep dive into the economic and environmental value of community recycling efforts and compared it to the value of other climate change mitigation practices, concluding it provides a return on investment.
Published New supply chain model to empower seabound hydrogen economy
(via sciencedaily.com) Original source A team of researchers has created a new supply chain model which could empower the international hydrogen renewable energy industry.
Published Ancient climate change solves mystery of vanished South African lakes
(via sciencedaily.com) Original source New evidence for the presence of ancient lakes in some of the most arid regions of South Africa suggests that Stone Age humans may have been more widespread across the continent than previously thought.
Published Half of world's largest lakes losing water
(via sciencedaily.com) Original source Fifty-three percent of the world's largest freshwater lakes are in decline, storing less water than they did three decades ago, according to a new study. The study analyzed satellite observations dating back decades to measure changes in water levels in nearly 2,000 of the world's biggest lakes and reservoirs. It found that climate change, human consumption and sedimentation are responsible.
Published New use for A.I.: Correctly estimating fish stocks
(via sciencedaily.com) Original source A newly published artificial intelligence (AI) algorithm is allowing researchers to quickly and accurately estimate coastal fish stocks without ever entering the water.
Published Driving on sunshine: Clean, usable liquid fuels made from solar power
(via sciencedaily.com) Original source Researchers have developed a solar-powered technology that converts carbon dioxide and water into liquid fuels that can be added directly to a car's engine as drop-in fuel.
Published Watch these cells rapidly create protrusions for exploration and movement
(via sciencedaily.com) Original source In order to move, cells must be able to rapidly change shape. A team of researchers show that cells achieve this by storing extra 'skin' in folds and bumps on their surface. This cell surface excess can be rapidly deployed to cover temporary protrusions and then folded away for next time.
Published A better way to study ocean currents
(via sciencedaily.com) Original source Computer scientists and oceanographers developed a machine-learning model that generates more accurate predictions about the velocities of ocean currents. The model could help make more precise weather forecasts or effectively predict how oil will spread after a spill.
Published Assessing emotions in wild animals
(via sciencedaily.com) Original source A new study examines indicators of mental wellbeing in wild animals to improve conservation efforts.
Published Physicists take the temperature of fluid flows and discover new role for turbulence
(via sciencedaily.com) Original source A team of physicists has discovered a new role for a specific type of turbulence -- a finding that sheds light on fluid flows ranging from the Earth's liquid core to boiling water.
