Published How blue-green algae manipulate microorganisms
(via sciencedaily.com) Original source A research team discovers previously unknown gene that indirectly promotes photosynthesis Protein regulator NirP1 influences the coordination of the nitrogen and carbohydrate metabolism 'Such protein regulators could in future be deployed in 'green' and 'blue' biotechnology for targeted control of the metabolism,' says geneticist.
Published Millions of gamers advance biomedical research
(via sciencedaily.com) Original source 4.5 million gamers around the world have advanced medical science by helping to reconstruct microbial evolutionary histories using a minigame included inside the critically and commercially successful video game, Borderlands 3. Their playing has led to a significantly refined estimate of the relationships of microbes in the human gut. The results of this collaboration will both substantially advance our knowledge of the microbiome and improve on the AI programs that will be used to carry out this work in future.
Published Switch to green wastewater infrastructure could reduce emissions and provide huge savings according to new research
(via sciencedaily.com) Original source Researchers have shown that a transition to green wastewater-treatment approaches in the U.S. that leverages the potential of carbon-financing could save a staggering $15.6 billion and just under 30 million tons of CO2-equivalent emissions over 40 years.
Published Researchers resolve old mystery of how phages disarm pathogenic bacteria
(via sciencedaily.com) Original source Bacterial infections pose significant challenges to agriculture and medicine, especially as cases of antibiotic-resistant bacteria continue to rise. In response, scientists are elucidating the ways that bacteria-infecting viruses disarm these pathogens and ushering in the possibility of novel treatment methods.
Published Researchers study effects of solvation and ion valency on metallopolymers
(via sciencedaily.com) Original source Researchers analyzed the effects of solvation and ion valency on metallopolymers, with implications for critical materials recovery and recycling, and environmental remediation.
Published New computer vision tool wins prize for social impact
(via sciencedaily.com) Original source A team of computer scientists working on two different problems -- how to quickly detect damaged buildings in crisis zones and how to accurately estimate the size of bird flocks -- recently announced an AI framework that can do both. The framework, called DISCount, blends the speed and massive data-crunching power of artificial intelligence with the reliability of human analysis to quickly deliver reliable estimates that can quickly pinpoint and count specific features from very large collections of images.
Published 'Surprising' hidden activity of semiconductor material spotted by researchers
(via sciencedaily.com) Original source New research suggests that materials commonly overlooked in computer chip design actually play an important role in information processing, a discovery which could lead to faster and more efficient electronics. Using advanced imaging techniques, an international team found that the material that a semiconductor chip device is built on, called the substrate, responds to changes in electricity much like the semiconductor on top of it.
Published Nanoscale movies shed light on one barrier to a clean energy future
(via sciencedaily.com) Original source New research is shedding light on one barrier to a clean energy future: corrosion. Using nanoscale imaging techniques, researchers have captured high-resolution videos of tiny crystals of ruthenium dioxide -- a key ingredient used to produce clean-burning hydrogen -- as they are eaten away by their acidic environment. The research could pave the way to more durable catalysts and dramatically extend the lifetime of devices needed to turn hydrogen green.
Published Breakthrough promises secure quantum computing at home
(via sciencedaily.com) Original source The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing.
Published Oxidant pollutant ozone removes mating barriers between fly species
(via sciencedaily.com) Original source Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to ozone and produce hybrid offspring. Since most of these offspring are unable to reproduce, the results could provide another explanation for the global decline of insects.
Published Using CO2 and biomass, researchers find path to more environmentally friendly recyclable plastics
(via sciencedaily.com) Original source Researchers have created a potential alternative to traditional petroleum-based plastic that is made from carbon dioxide (CO2) and lignin, a component of wood that is a low-cost byproduct of paper manufacturing and biofuel production.
Published A faster, better way to prevent an AI chatbot from giving toxic responses
(via sciencedaily.com) Original source A new technique can more effectively perform a safety check on an AI chatbot. Researchers enabled their model to prompt a chatbot to generate toxic responses, which are used to prevent the chatbot from giving hateful or harmful answers when deployed.
Published Novel UV broadband spectrometer revolutionizes air pollutant analysis
(via sciencedaily.com) Original source A research team has developed a broadband UV dual-comb spectrometer with which air pollutants can be continually measured and their reaction with the environment can be observed in real time.
Published Waterproof 'e-glove' could help scuba divers communicate
(via sciencedaily.com) Original source When scuba divers need to say 'I'm okay' or 'Shark!' to their dive partners, they use hand signals to communicate visually. But sometimes these movements are difficult to see. Now, researchers have constructed a waterproof 'e-glove' that wirelessly transmits hand gestures made underwater to a computer that translates them into messages. The new technology could someday help divers communicate better with each other and with boat crews on the surface.
Published A microbial plastic factory for high-quality green plastic
(via sciencedaily.com) Original source Engineered bacteria can produce a plastic modifier that makes renewably sourced plastic more processable, more fracture resistant and highly biodegradable even in sea water. The development provides a platform for the industrial-scale, tunable production of a material that holds great potential for turning the plastic industry green.
Published New device gathers, stores electricity in remote settings
(via sciencedaily.com) Original source Wirelessly connected devices perform an expanding array of applications, such as monitoring the condition of machinery and remote sensing in agricultural settings. These applications hold much potential for improving the efficiency, but how do you power these devices where reliable electrical sources are not available? Research points to a possible solution in the form of a novel type of battery.
Published Scientist helps link climate change to Madagascar's megadrought
(via sciencedaily.com) Original source A team reveals a clear link between human-driven climate change and the years-long drought currently gripping southern Madagascar.
Published Subterranean storage of hydrogen
(via sciencedaily.com) Original source Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.
Published Atmospheric and economic drivers of global air pollution
(via sciencedaily.com) Original source Carbon monoxide emissions from industrial production have serious consequences for human health and are a strong indicator of overall air pollution levels.
