Published Driving on sunshine: Clean, usable liquid fuels made from solar power



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



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



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



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



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



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



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



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



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.
Published Porous crystals made from plant extracts purify water from pharmaceutical pollutants



Researchers have developed porous crystals made from pomegranate extract to capture and degrade pharmaceutical molecules found in local municipal wastewater.
Published Land use linked to water quality and quantity



Researchers recently published a study that focuses on the Sudbury-Assabet and Concord watershed in eastern Massachusetts, and which links hydrological changes, including floods, drought and runoff, to changing patterns of land use.
Published Metal-filtering sponge removes lead from water



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.
Published 'Improved' cookstoves emit more ultrafine particles than conventional stoves



Improved cookstoves, which are widely used for cooking in developing countries, produce twice as many harmful ultrafine air pollution particles (PM0.1) as conventional stoves, according to a new study.
Published Great Basin: History of water supply in one of the driest regions in the USA



An international team has reconstructed the evolution of groundwater in the Great Basin, USA -- one of the driest regions on Earth -- up to 350,000 years into the past with unprecedented accuracy. The results shed new light on the effects of climate change on water supply and provide important insights for the sustainable use of groundwater resources.
Published Global warming puts whales in the Southern Ocean on a diet



In the autumn, when right whales swim towards the coasts of South Africa, they ought to be fat and stuffed full. But in recent years, they have become thinner because their food is disappearing with the melting sea ice.
Published Hammerhead sharks hold their breath on deep water hunts to stay warm



Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.
Published Dark clouds on the horizon



Our industrialized society releases many and various pollutants into the world. Combustion in particular produces aerosol mass including black carbon. Although this only accounts for a few percent of aerosol particles, black carbon is especially problematic due to its ability to absorb heat and impede the heat reflection capabilities of surfaces such as snow. So, it's essential to know how black carbon interacts with sunlight. Researchers have quantified the refractive index of black carbon to the most accurate degree yet which might impact climate models.
Published Unlocking the power of photosynthesis for clean energy production



Researchers are embarking on a groundbreaking project to mimic the natural process of photosynthesis using bacteria to deliver electrons to a nanocrystal semiconductor photocatalyst. By leveraging the unique properties of microorganisms and nanomaterials, the system has the potential to replace current approaches that derive hydrogen from fossil fuels, revolutionizing the way hydrogen fuel is produced and unlocking a powerful source of renewable energy.
Published Water warming study shows unexpected impact on fish size



The theory that water-breathing animals such as fish will shrink due to global warming has been called into question by a new study.
Published Cleanup of inactive Gulf of Mexico wells estimated at $30 billion



A new article examines the cost to plug 14,000 wells that are inactive, have not produced for five years and are unlikely to be reactivated in the Gulf of Mexico region, which is the epicenter of U.S. offshore oil and gas operations.
