Published Surfactants can cause toxic chemicals in aerosols to last longer in the air
(via sciencedaily.com) Original source Research has found that hazardous chemicals commonly encountered in aerosols, such as those produced by cooking and cleaning, can be 'protected' in 3D structures formed by surfactants, causing them to last longer in the air.
Published Fall snow levels can predict a season's total snowpack in some western states
(via sciencedaily.com) Original source Research found that, in some western states, the amount of snow already on the ground by the end of December is a good predictor of how much total snow that area will get.
Published Hot summer air turns into drinking water with new gel device
(via sciencedaily.com) Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.
Published Atmospheric scientists reveal much of Houston's ozone exceedance due to air flows from the north
(via sciencedaily.com) Original source Atmospheric science researchers published findings on Houston's ozone. They found that while local emissions play a role in the rise of Houston's ozone levels, most of the pollutants are carried in from other parts of the country.
Published Urban parks built on former waste incineration sites could be lead hotspots
(via sciencedaily.com) A new study finds that surface soil in parks and playgrounds built on former waste incineration and ash disposal sites may contain levels of lead exceeding EPA safety standards for areas where children play. The contamination, which can persist long after an incinerator is closed, stems from burning paint, pipes and other products that contained lead. Sites in hundreds of U.S. and Canadian cities could be contaminated. Increased monitoring is needed to pinpoint hotspots.
Published High levels of particulate air pollution associated with increased breast cancer incidence
(via sciencedaily.com) Original source Researchers found that living in an area with high levels of particulate air pollution was associated with an increased incidence of breast cancer. The study is one of the largest studies to date looking at the relationship between outdoor air pollution, specifically fine particulate matter, and breast cancer incidence.
Published Super antifreeze in cells: The ability to survive in ice and snow developed in animals far earlier than we thought
(via sciencedaily.com) Original source More than 400 million years ago, an insect-like animal called the springtail developed a small protein that prevents its cells from freezing.
Published New methodology reveals health, climate impacts of reducing buildings' energy use
(via sciencedaily.com) Increasing energy efficiency in buildings can save money -- and it can also decrease the carbon emissions and air pollution that lead to climate change and health harms. But the climate and health benefits of reducing buildings' energy consumption are rarely quantified. Now, researchers have developed a new method for calculating the health and climate impacts of these energy savings.
Published Studies highlight new approaches to addressing climate change
(via sciencedaily.com) Original source Failing to achieve climate mitigation goals puts increasing pressure on climate adaptation strategies. In two new studies, researchers address novel approaches to these issues.
Published New ionic materials boost hydrogen fuel cell efficiency!
(via sciencedaily.com) A research team has made a groundbreaking advancement in improving the efficiency of hydrogen fuel cells, which are gaining significant attention as eco-friendly next-generation energy sources.
Published Researcher helps boost immune system memory against influenza
(via sciencedaily.com) Original source Researchers are one step closer to making the T cell army stronger. In a recent study, researchers found that by manipulating one molecular signaling pathway in the T cells that participate in clearing influenza virus in the lungs, the strength and longevity of immunological memory produced can be improved.
Published Helicopter-based observations uncover warm ocean water flows toward Totten Ice Shelf in Southeast Antarctica
(via sciencedaily.com) Original source An international team of scientists has successfully conducted large-scale helicopter-based observations along the coast of East Antarctica and has identified pathways through which warm ocean water flows from the open ocean into ice shelf cavities for the first time.
Published Lions on the brink -- New analysis reveals the differing threats to African lion populations
(via sciencedaily.com) Original source New results reveal that many of Africa's remaining lions live within small, fragmented populations at risk of disappearing. The researchers developed a new framework which integrates ecological and socio-political risk factors to better understand the fragility of these populations.
Published Researchers charting a sustainable course in oceanic carbon capture
(via sciencedaily.com) Original source As researchers around the world race against time to develop new strategies and technologies to fight climate change, a team of scientists is exploring one possible way to directly reduce the amount of carbon dioxide in the environment: Negative emissions technologies (NETs).
Published Hybrid catalyst produces critical fertilizer and cleans wastewater
(via sciencedaily.com) Original source Synthetically produced fertilizer urea supports half of global population. Using pure metals, researchers develop hybrid catalyst with capacity to convert waste nitrogen and carbon dioxide to urea. The process could denitrify wastewater and runoff while creating a new revenue stream for water treatment facilities.
Published Floating sea farms: A solution to feed the world and ensure fresh water by 2050
(via sciencedaily.com) Original source The sun and the sea -- both abundant and free -- are being harnessed in a unique project to create vertical sea farms floating on the ocean that can produce fresh water for drinking and agriculture.
Published Scientists find evidence of sea star species hybridization
(via sciencedaily.com) A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.
Published Nutrients drive cellular reprogramming in the intestine
(via sciencedaily.com) Original source Researchers have unveiled an intriguing phenomenon of cellular reprogramming in mature adult organs, shedding light on a novel mechanism of adaptive growth. The study, which was conducted on fruit flies (Drosophila), provides further insights into dedifferentiation -- where specialized cells that have specific functions transform into less specialized, undifferentiated cells like stem cells.
Published Table salt could be the secret ingredient for better chemical recycling
(via sciencedaily.com) Original source Researchers have shown that table salt outperforms other expensive catalysts being explored for the chemical recycling of polyolefin polymers, which account for 60% of plastic waste. The research shows that sodium chloride could provide a safe, inexpensive and reusable way to make plastics more recyclable. The team also showed that table salt and other catalysts could be used in the recycling of metallized plastic films -- like those used in potato chip bags -- which are currently not recyclable.
Published These worms have rhythm
(via sciencedaily.com) Original source Researchers have developed a new imaging technique to observe active gene expression in real time. They found that four molecules work together to control the timing of each stage of the C. elegans worm's development. This timekeeping process could provide important clues about the natural rhythm of development in humans and other animals.
