Published Simultaneous atmospheric and marine observations directly beneath a violent, Category 5 typhoon in the North-West Pacific
(via sciencedaily.com) Original source Scientists have successfully conducted a simultaneous marine and atmospheric measurements at multiple locations directly beneath a violent, Category 5, which is the strongest class, typhoon in the North-West Pacific, before it reached land.
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 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 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 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.
Published Chemical exposure may raise your risk for Parkinson's
(via sciencedaily.com) Original source Two years of heavy exposure to TCE, a liquid chemical that lingers in the air, water and soil, may increase the risk of Parkinson's disease by 70%.
Published African smoke over the Amazon
(via sciencedaily.com) Original source Up to two-thirds of the soot above the central Amazon rainforest originates in Africa. Researchers differentiate soot particles using their relative properties and attribute them to their respective points of origin. They found that bush fires and burning savannah in the north and south of Africa make a substantial contribution to air pollution in the central Amazon all year round, thereby playing an important role in the earth radiation budget and water cycle. This is caused by the efficient transatlantic transport of particles through the atmosphere.
Published About 13,000 years ago, the water outflow from the Mediterranean to the Atlantic Ocean was twice that of today’s
(via sciencedaily.com) Original source About 13,000 years ago, a climate crisis caused a global drop in temperatures in the northern hemisphere. This episode of intense cold, known as the Younger Dryas, also caused severe aridity across the Mediterranean basin, which had a major impact on terrestrial and marine ecosystems. But what do we know about the impact of this climate change on water circulation in the Mediterranean?
Published South Africa's desert-like interior may have been more inviting to our human ancestors
(via sciencedaily.com) Original source Lining the Cape of South Africa and its southern coast are long chains of caves that nearly 200,000 years ago were surrounded by a lush landscape and plentiful food.
