Published Drawing water from dry air (via sciencedaily.com) Original source
A prototype device harvests drinking water from the atmosphere, even in arid places.
Published Better carbon storage with stacked geology (via sciencedaily.com) Original source
According to new research subsurface reservoirs that are covered by a collection of hundreds of smaller lids -- collectively called a 'composite confining system' -- may be the better option for keeping carbon trapped for the long term. That's good news for the carbon storage industry. This type of distributed system is common in a range of geological environments.
Published Researchers develop more environmentally friendly and cost-effective method for soil remediation (via sciencedaily.com) Original source
Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
Published A promising new method uses light to clean up forever chemicals (via sciencedaily.com) Original source
A room-temperature method to decompose perfluoroalkyl substances (PFASs) using visible LED light offers a promising solution for sustainable fluorine recycling and PFAS treatment.
Published Converting captured carbon to fuel: Study assesses what's practical and what's not (via sciencedaily.com) Original source
A new analysis sheds light on major shortfalls of a recently proposed approach to capture CO2 from air and directly convert it to fuel using electricity. The authors also provide a new, more sustainable, alternative.
Published Ecologists discover rare fiddler crab species on Hong Kong coast highlighting the impact of climate change and coastal development (via sciencedaily.com) Original source
Researchers have made an exciting discovery on the Hong Kong coast. They have identified two fiddler crab species: Tubuca dussumieri, previously recorded in old literature but never confirmed in recent times, and Tubuca. coarctata, which has never been seen in Hong Kong. These findings not only confirm the presence of these insular species in Hong Kong but also explore the potential impact of climate change on their distribution.
Published Maximizing hydrogen peroxide formation during water electrolysis (via sciencedaily.com) Original source
When water is split electrolytically, the result is typically hydrogen -- and 'useless' oxygen. Instead of oxygen, you can also produce hydrogen peroxide, which is required for many branches of industry. This, however, requires certain reaction conditions.
Published Fish adjust reproduction in response to predators (via sciencedaily.com) Original source
Some species of fish can evolve their egg-laying habits in response to predators in the area in order to survive, according to new research.
Published New humidity-driven membrane to remove carbon dioxide from the air (via sciencedaily.com) Original source
A new ambient-energy-driven membrane that pumps carbon dioxide out of the air has been developed by researchers.
Published How pollution may remain in water after oil spill cleanups (via sciencedaily.com) Original source
The way oil drops break up at the water's surface means some oil may not get cleaned up after a spill.
Published Solar farms with stormwater controls mitigate runoff, erosion, study finds (via sciencedaily.com) Original source
As the number of major utility-scale ground solar panel installations grows, concerns about their impacts on natural hydrologic processes also have grown. However, a new study by Penn State researchers suggests that excess runoff or increased erosion can be easily mitigated -- if these 'solar farms' are properly built.
Published Rural belts around cities can reduce urban summer temperatures by up to 0.5°C (via sciencedaily.com) Original source
The key to cooling 'urban heat islands' may lie in the countryside, according to a new study.
Published Microbes found to destroy certain 'forever chemicals' (via sciencedaily.com) Original source
An environmental engineering team has discovered that specific bacterial species can cleave the strong fluorine-to-carbon bond certain kinds of 'forever chemical' water pollutants, offering promise for low-cost treatments of contaminated drinking water.
Published Diatom surprise could rewrite the global carbon cycle (via sciencedaily.com) Original source
When it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide swaths of the ocean. These new findings could lead to reduced estimates regarding how much carbon dioxide diatoms pull out of the air via photosynthesis, which in turn, could alter our understanding of the global carbon cycle, which is especially relevant given the changing climate.
Published Aussie innovation spearheads cheaper seafloor test for offshore wind farms (via sciencedaily.com) Original source
Australian engineers have unveiled a clever new device -- based on a modified speargun -- as a cheap and efficient way to test seabed soil when designing offshore wind farms.
Published Smart soil can water and feed itself (via sciencedaily.com) Original source
A newly engineered type of soil can capture water out of thin air to keep plants hydrated and manage controlled release of fertilizer for a constant supply of nutrients.
Published Microplastic pollution increases sea foam height and stability (via sciencedaily.com) Original source
Researchers examine the specific impacts of microplastics on the geophysics of sea foam formation in the critical zone where water meets air in the top layer of the ocean. They devised two simulations for their work -- a column filled with sea water injected with air and a laboratory-scale breaking wave channel to test the impacts of wave height on sea foam in the surface microlayer -- and tested their effects on sea foam formation, stability, and duration.
Published Weather experts discover new effect of storm -- in a teacup (via sciencedaily.com) Original source
A new study reveals that Storm Ciaran cut an invisible path of mayhem across southern Britain last autumn, destroying any possibility that 20 million people could have a proper cup of tea at breakfast. The storm's record-breaking low pressure meant the boiling point of water was below the crucial 100 degrees Celsius required for a decent cuppa.
Published Additional taxes vs. water quotas: Study compares the most effective system to manage water consumption in agriculture (via sciencedaily.com) Original source
A new study finds that the proportional allocation of water, and not additional taxes on the resource, is more effective from the point of view of those engaged in agriculture.
Published Producing hydrogen and fertilizer at the same time (via sciencedaily.com) Original source
This new concept could allow the needs of previously separate industries to be combined: the production of hydrogen and the production of fertilizer.
