Published Even Sonoran Desert plants aren't immune to climate change
(via sciencedaily.com) In North America's hottest, driest desert, climate change is causing the decline of plants once thought nearly immortal and replacing them with shorter shrubs that can take advantage of sporadic rainfall and warmer temperatures.
Published Eco-efficient cement could pave the way to a greener future
(via sciencedaily.com) Scientists develop process to remove toxic heavy metals from coal fly ash, making for greener, stronger concrete.
Published Tiny yet hazardous: New study shows aerosols produced by contaminated bubble bursting are far smaller than predicted
(via sciencedaily.com) New research has shown that bursting bubbles coated by a thin oil layer produce drops with smaller sizes, greater overall number of drops, and are ejected at a higher velocity, compared to bubbles generated in clean water.
Published Surprise effect: Methane cools even as it heats
(via sciencedaily.com) Most climate models do not yet account for a recent discovery: methane traps a great deal of heat in Earth's atmosphere, but also creates cooling clouds that offset 30% of the heat.
Published Microplastics limit energy production in tiny freshwater species
(via sciencedaily.com) Microplastic pollution reduces energy production in a microscopic creature found in freshwater worldwide, new research shows.
Published Closed loop for circular economy: New polymer recycling strategy ensures both high stability and complete recyclability
(via sciencedaily.com) Large amounts of plastic waste are incinerated or deposited in landfills. This degrades the environment and depletes valuable resources. In this light, recycling plastics such as polymers is promising. However, recycling diminishes their quality. Recently, researchers have proposed a 'closed-loop' recycling process based on polymer microparticles. It produces fully recyclable polymer films with high mechanical stability and fracture energy, which they retain upon recycling.
Published New wood-based technology removes 80% of dye pollutants in wastewater
(via sciencedaily.com) Researchers have developed a new method that can easily purify contaminated water using a cellulose-based material. This discovery could have implications for countries with poor water treatment technologies and combat the widespread problem of toxic dye discharge from the textile industry.
Published Genome of a drought-tolerant plant: Many genes are involved in 'resurrection'
(via sciencedaily.com) Some plants can survive months without water, only to turn green again after a brief downpour. A recent study shows that this is not due to a 'miracle gene.' Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties.
Published Phytoplankton blooms offer insight into impacts of climate change
(via sciencedaily.com) The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.
Published New water treatment zaps 'forever chemicals' for good
(via sciencedaily.com) Engineers have developed a new water treatment that removes 'forever chemicals' from drinking water safely, efficiently -- and for good.
Published Next epidemic could be spotted early in wastewater
(via sciencedaily.com) Original source Researchers behind the UK's first pilot public health surveillance system based on analysis of wastewater say that routine monitoring at sewage treatment works could provide a powerful early warning system for the next flu or norovirus epidemic, alerting hospitals to prepare and providing public health agencies with vital health information.
Published Researchers get to the 'bottom' of how beetles use their butts to stay hydrated
(via sciencedaily.com) Beetles are champions at surviving in extremely dry environments. In part, this property is due to their ability to suck water from the air with their rear ends. A new study explains just how. Beyond helping to explain how beetles thrive in environments where few other animals can survive, the knowledge could eventually be used for more targeted and delicate control of global pests such as the grain weevil and red flour beetle.
Published The devil is in the details: Re-imagining fertilizer precursor synthesis
(via sciencedaily.com) Researchers have improved the Faradaic efficiency of the nitrogen reduction reaction into ammonia by straightforward optimization of chemical process parameters. They found that trace water was the probable source of the high selectivity by facilitating incorporation of lithium oxide into the solid electrolyte interphase. These findings will also aid optimization of other analogous reactions, and thus help the chemicals industry optimize the sustainability of one of the most carbon-intensive reactions globally.
Published Synthesis gas and battery power from sunlight energy
(via sciencedaily.com) Plants use photosynthesis to harvest energy from sunlight. Now researchers have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.
Published 3000+ billion tons of ice lost from Antarctic Ice Sheet over 25 years
(via sciencedaily.com) Original source Scientists have calculated that the fastest changing Antarctic region?-?the Amundsen Sea Embayment?-?has lost more than 3,000 billion tonnes of ice over a 25-year?period.??
Published Nitrate can release uranium into groundwater
(via sciencedaily.com) A team has experimentally confirmed that nitrate, a compound common in fertilizers and animal waste, can help transport naturally occurring uranium from the underground to groundwater. The new research backs a previous study showing that aquifers contaminated with high levels of nitrate -- including the High Plains Aquifer residing beneath Nebraska -- also contain uranium concentrations far exceeding a threshold set by the Environmental Protection Agency. Uranium concentrations above that EPA threshold have been shown to cause kidney damage in humans, especially when regularly consumed via drinking water.
Published Douglas-fir in Klamath Mountains are in 'decline spiral'
(via sciencedaily.com) Increases in mortality among Douglas-fir in the Klamath Mountains are the result of multiple factors that have the iconic tree in a 'decline spiral' in parts of the region.
Published Biodiversity amid climate change
(via sciencedaily.com) Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.
Published Scientists use tardigrade proteins for human health breakthrough
(via sciencedaily.com) Original source Natural and engineered versions of tardigrade proteins can be used to stabilize an important pharmaceutical used to treat people with hemophilia and other conditions without the need for refrigeration -- even amid high temperatures and other difficult conditions.
Published Jellyfish size might influence their nutritional value
(via sciencedaily.com) Researchers confirmed what was already known: jellyfish eat bigger prey as they grow, which means they also occupy a higher position in the food web as they grow. They also found that some of the concentrations of 'healthy fats,' increase as jellyfish grow. These changes might be influenced by their diet, and as they feed on bigger prey with higher levels of fatty acids, the jellyfish accumulate more of these fatty acids.
