Published 'Find pearls in the soil' unveiling the magic of hydrogen production from municipal sewage
(via sciencedaily.com) Original source Scientists have developed a catalyst for the urea oxidation reaction, enhancing hydrogen generation efficiency.
Published Multiple air pollutants linked to asthma symptoms in children
(via sciencedaily.com) Original source Exposure to several combinations of toxic atmospheric pollutants may be triggering asthma symptoms among children, a recent analysis suggests. The study showed that 25 different combinations of air pollutants were associated with asthma symptoms among 269 elementary school children diagnosed with asthma.
Published New computational strategy boosts the ability of drug designers to target proteins inside the membrane
(via sciencedaily.com) Original source Hitting targets embedded within the cell membrane has long been difficult for drug developers due to the membrane's challenging biochemical properties. Now, chemists have demonstrated new custom-designed proteins that can efficiently reach these 'intramembrane' targets.
Published Sustainable plastics from agricultural waste
(via sciencedaily.com) Original source Scientists have developed a sustainable method to make high-performance plastics from agricultural leftovers, turning them into valuable materials.
Published Federal housing programs protect residents from lead exposure
(via sciencedaily.com) Original source Americans already living in housing supported by federal housing assistance programs have significantly lower blood lead levels than counterparts who would later join these programs, according to new research.
Published Curbing coal-burning emissions translates to health gains for children
(via sciencedaily.com) Original source Research finds a nearly 40% decline in the annual average concentration of respirable particulate matter (PM2.5) in Krakow, Poland, between 2010 and 2019 following the implementation of clean air policies. Air quality improvements translated to substantial benefits for children's outcomes, including fewer cases of asthma and better birth outcomes.
Published Milk to the rescue for diabetics? Cow produces human insulin in milk
(via sciencedaily.com) Original source An unassuming brown bovine from the south of Brazil has made history as the first transgenic cow capable of producing human insulin in her milk. The advancement could herald a new era in insulin production, one day eliminating drug scarcity and high costs for people living with diabetes.
Published Molecular simulations of ammonia mixtures support search for renewable fuels
(via sciencedaily.com) Original source Ammonia is an important molecule with many applications. The end product of the famed Haber-Bosch process, it is commonly synthesized to capture nitrogen for fertilizers, and is used for refrigeration, in cleaning products, and in the production of pharmaceuticals. Recently, this modest molecule has also attracted interest as a potential resource for addressing one of today's most pressing challenges -- the need for reliable and abundant renewable fuels.
Published New high-performance solar cell material
(via sciencedaily.com) Original source A new study reports the discovery of an entirely new stable, earth-abundant, high-performance material for solar absorbers -- the central part of a solar cell that turns light into electricity. While identifying new solar materials is typically very time-consuming, the researchers used a unique high-throughput computational screening method to quickly evaluate around 40,000 candidate materials.
Published AI analysis of historical satellite images show USSR collapse in 1990s increased methane emissions, despite lower oil and gas production
(via sciencedaily.com) Original source An AI-powered analysis of 25 years of satellite images yields the surprising finding that methane emissions in Turkmenistan, a former Soviet republic and major oil-producing region, actually increased in the years following the dissolution of the Soviet Union.
Published A simple and robust experimental process for protein engineering
(via sciencedaily.com) Original source A protein engineering method using simple, cost-effective experiments and machine learning models can predict which proteins will be effective for a given purpose, according to a new study.
Published Giant sequoias are a rapidly growing feature of the UK landscape
(via sciencedaily.com) Original source Imported giant sequoia trees are well adapted to the UK, growing at rates close to their native ranges and capturing large amounts of carbon during their long lives, finds a new study.
Published New study quantifies health impacts from oil and gas flaring in U.S.
(via sciencedaily.com) Original source A new study finds that pollution from oil and gas venting and flaring results in $7.4 billion in health damages, more than 700 premature deaths, and 73,000 asthma exacerbations among children annually. Researchers also conclude that emissions are underreported and controlling emissions is not only profitable for operators, but also can significantly improve public health in surrounding communities.
Published Scientists find weak points on Epstein-Barr virus
(via sciencedaily.com) Original source Studies of interactions between two lab-generated monoclonal antibodies (mAbs) and an essential Epstein-Barr virus (EBV) protein have uncovered targets that could be exploited in designing treatments and vaccines for this extremely common virus.
Published Vehicle brakes produce charged particles that may harm public health
(via sciencedaily.com) Original source Scientists know relatively little about particles released into the air when a vehicle driver brakes, though evidence suggests those particles may be more harmful to health than particles exiting the tailpipe.
Published AI making waves in marine data collection
(via sciencedaily.com) Original source Numerous measurement stations around the world provide us with data about air quality, allowing us to enhance it. Although we are increasingly collecting data from marine areas, access to such data is considerably more challenging. Signals are poorly transmitted through water, differences in both pressure and currents hinder measurement devices and there is an absence of pre-constructed computing infrastructure. Could intelligent technologies help us improve marine data collection?
Published How a natural compound from sea squirts combats cancer
(via sciencedaily.com) Original source Trabectedin, a promising drug derived from the sea squirt Ecteinascidia turbinata, has shown potential in combating cancers resistant to conventional treatments. However, its precise mechanism of action has remained elusive -- until now.
Published Air filters and scheduled window opening can reduce classroom pollution by up to 36%
(via sciencedaily.com) Original source To improve air quality in classrooms, schools should use air purifiers during the school day and open the windows after hours. That's according to a new study.
Published Mars attracts: How Earth's interactions with the red planet drive deep-sea circulation
(via sciencedaily.com) Original source Scientists have used the geological record of the deep sea to discover a connection between the orbits of Earth and Mars, past global warming patterns and the speeding up of deep ocean circulation. The patterns they discover suggest that warming seas could produce deep whirpools in ocean currents.
Published Rainforest's next generation of trees threatened 30 years after logging
(via sciencedaily.com) Original source Rainforest seedlings are more likely to survive in natural forests than in places where logging has happened -- even if tree restoration projects have taken place, new research shows.
