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.

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.

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.

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.

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.

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.

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?

Scientists reveal breakthrough that could lead to cleaner hydrogen energy      (via sciencedaily.com)     Original source 

Chemists have taken a big step toward splitting hydrogen and oxygen molecules to make pure hydrogen -- without using fossil fuels. Results from pulse radiolysis experiments have laid bare the complete reaction mechanism for an important group of 'water-splitting' catalysts. The work means scientists are closer to making pure hydrogen from renewable energy, an energy source that could contribute to a greener future for the nation and world.

Metal-filtering sponge removes lead from water      (via sciencedaily.com)     Original source 

Engineers have developed a new sponge that can remove metals -- including toxic heavy metals like lead and critical metals like cobalt -- from contaminated water, leaving safe, drinkable water behind. In proof-of-concept experiments, the researchers tested their new sponge on a highly contaminated sample of tap water, containing more than 1 part per million of lead. With one use, the sponge filtered lead to below detectable levels.
