Published Mimicking biological enzymes may be key to hydrogen fuel production
(via sciencedaily.com) An ancient biological enzyme known as nickel-iron hydrogenase may play a key role in producing hydrogen for a renewables-based energy economy, researchers said. Careful study of the enzyme has led chemists to design a synthetic molecule that mimics the hydrogen gas-producing chemical reaction performed by the enzyme.
Published Detecting coral biodiversity in seawater samples
(via sciencedaily.com) Researchers have developed a method to measure coral biodiversity through extracting the environmental DNA (or eDNA) from a liter of surface seawater collected from above a reef. The method has been confirmed to work through observations made by scientific divers in the same areas of ocean. This has paved the way for large-scale comprehensive surveys of reef-building coral to take place and removes the reliance of direct observations made through scientific scuba diving or snorkeling.
Published Fermented coffee's fruity aromas demystified
(via sciencedaily.com) Fermented coffee could bring a fruity taste to your morning cup of joe. This new kind of beverage has a raspberry-like taste and aroma, but what causes these sensations has been a mystery. Scientists now report six compounds that contribute to the fermented coffee experience.
Published Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions
(via sciencedaily.com) Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.
Published Pulsing ultrasound waves could someday remove microplastics from waterways
(via sciencedaily.com) Colorful particles of plastic drift along under the surface of most waterways. These barely visible microplastics -- less than 5 mm wide -- are potentially harmful to aquatic animals and plants, as well as humans. Now, a team reports a two-stage device made with steel tubes and pulsing sound waves that removes most of the plastic particles from real water samples.
Published SMART warnings could protect communities at risk from flooding
(via sciencedaily.com) Engaging communities in developing a real-time early warning system could help to reduce the often-devastating impact of flooding on people and property -- particularly in mountainous regions where extreme water events are a 'wicked' problem, a new study reveals.
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 Artificial intelligence discovers secret equation for 'weighing' galaxy clusters
(via sciencedaily.com) Astrophysicists have leveraged artificial intelligence to uncover a better way to estimate the mass of colossal clusters of galaxies. The AI discovered that by just adding a simple term to an existing equation, scientists can produce far better mass estimates than they previously had. The improved estimates will enable scientists to calculate the fundamental properties of the universe more accurately, the astrophysicists have reported.
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 AI finds the first stars were not alone
(via sciencedaily.com) Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.
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 Neutrinos made by a particle collider detected
(via sciencedaily.com) Physicists have detected neutrinos created by a particle collider. The discovery promises to deepen scientists' understanding of the subatomic particles, which were first spotted in 1956 and play a key role in the process that makes stars burn.
