Published New way to count microbes speeds research, cuts waste, could lead to new antibiotics
(via sciencedaily.com) Original source Researchers have developed a new way of counting microorganisms that works as much as 36 times faster than conventional methods, cuts plastic use more than 15-fold and substantially decreases the cost and carbon footprint of biomedical research. The technique could revolutionize the way microbiology experiments are conducted, allowing researchers to test potential new antibiotics in a fraction of the time.
Published Scientists use quantum biology, AI to sharpen genome editing tool
(via sciencedaily.com) Original source Scientists used their expertise in quantum biology, artificial intelligence and bioengineering to improve how CRISPR Cas9 genome editing tools work on organisms like microbes that can be modified to produce renewable fuels and chemicals.
Published Plastics treaty must tackle problem at source
(via sciencedaily.com) Original source The new Global Plastics Treaty must tackle the problem at source, researchers say. They say the treaty must prioritize 'upstream' issues: cutting total production and consumption of plastics, phasing out hazardous chemicals and tackling fossil fuel subsidies.
Published Liquid metals shake up century-old chemical engineering processes
(via sciencedaily.com) Original source Liquid metals could be the long-awaited solution to 'greening' the chemical industry, according to researchers who tested a new technique they hope can replace energy-intensive chemical engineering processes harking back to the early 20th century.
Published A fifth of European Red List flora and fauna species may be at risk of extinction
(via sciencedaily.com) Original source A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species.
Published Southern Alaska's national forests key to meeting climate, conservation goals
(via sciencedaily.com) Original source Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.
Published Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken
(via sciencedaily.com) Original source Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken. Other threats to UK forests include competition with society for water, viral diseases, and extreme weather affecting forest management.
Published Device 'smells' seawater to discover, detect novel molecules
(via sciencedaily.com) Original source Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.
Published The secret to longer lasting batteries might be in how soap works
(via sciencedaily.com) Original source Researchers show that one of the most promising substances for designing longer lasting lithium batteries form micelle-like structures like they do in soap.
Published Scaling up nano for sustainable manufacturing
(via sciencedaily.com) Original source A research team has developed a high-performance coating material that self-assembles from 2D nanosheets, and which could significantly extend the shelf life of electronics, energy storage devices, health & safety products, and more. The researchers are the first to successfully scale up nanomaterial synthesis into useful materials for manufacturing and commercial applications.
Published 'Biodiversity time machine' provides insights into a century of loss
(via sciencedaily.com) Original source AI analysis shows pollution levels, extreme weather events and increasing temperatures devastates biodiversity in freshwater lakes.
Published City and highway lights threaten mountain lion habitats
(via sciencedaily.com) Original source Artificial light pollution at night threatens mountain lion habitat, making it a factor to consider for wildlife crossings and land use, finds a new study.
Published Lightening the load: Researchers develop autonomous electrochemistry robot
(via sciencedaily.com) Original source Researchers have developed an automated laboratory robot to run complex electrochemical experiments and analyze data. The Electrolab will be used to explore next-generation energy storage materials and chemical reactions that promote alternative and sustainable energy.
Published New algae species rewrites understanding of reef systems
(via sciencedaily.com) Original source An international team of marine scientists has identified and officially named four species of algae new to science, challenging previous taxonomical assumptions within the Porolithon genus. The discovery has far-reaching implications for our understanding of the ecological role of these algae in the coral reef ecosystem.
Published Threatened sharks and rays caught off Cyprus
(via sciencedaily.com) Original source Sharks and rays from threatened species are being caught off northern Cyprus, according to a new study by scientists who are working with local authorities and fishers to protect the animals.
Published Crust-forming algae are displacing corals in tropical waters worldwide
(via sciencedaily.com) Original source Over the past few decades, algae have been slowly edging corals out of their native reefs across the globe by blocking sunlight, wearing the corals down physically, and producing harmful chemicals. But in recent years, a new type of algal threat has surfaced in tropical regions like the Caribbean -- one that spreads quickly and forms a crust on top of coral and sponges, suffocating the organisms underneath and preventing them from regrowing. Marine biologists report that peyssonnelioid alga crusts, or PACs, are expanding quickly across reefs worldwide, killing off corals and transforming entire ecosystems.
Published New approach to water electrolysis for green hydrogen
(via sciencedaily.com) Original source Scientists have pioneered a novel approach to water electrolysis catalysts for green hydrogen production.
Published Photo battery achieves competitive voltage
(via sciencedaily.com) Original source Researchers have developed a monolithically integrated photo battery using organic materials. The photo battery achieves an unprecedented high discharge potential of 3.6 volts. The system is capable of powering miniature devices.
Published Charged 'molecular beasts' the basis for new compounds
(via sciencedaily.com) Original source Mass spectrometers are high-tech machines that play an important role in our society. They are highly sensitive analytical instruments that are indispensable in areas such as medical diagnostics, food quality control and the detection of hazardous chemical substances. A research group is working to modify mass spectrometers so that they can be used for a completely different purpose: the chemical synthesis of new molecules.
Published Large herbivores such as elephants, bison and moose contribute to tree diversity
(via sciencedaily.com) Original source Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.
