Published What's the weather like in the deep sea?
(via sciencedaily.com) Original source A new study has revealed how even the deepest seafloors are affected by the daily back-and-forth of the tides, and the change of the seasons, and that currents at the bottom of the ocean are far more complicated than previously thought. These findings are helping us understand the deep-sea pathways of nutrients that support important deep-sea ecosystems, assess where microplastics and other pollutants accumulate in the ocean, and reconstruct past climate change.
Published Researchers explore the potential of clean energy markets as a hedging tool
(via sciencedaily.com) Original source Clean energy investments offer potential stability and growth, especially during volatile market conditions. A recent study explored the relationship between clean energy markets and global stock markets. Significant spillovers were observed from major indices like the SP500 to markets such as Japan's Nikkei225 and Global Clean Energy Index. These interactions suggest opportunities for optimizing investment portfolios and leveraging clean energy assets as hedging tools in volatile market environments.
Published New principle for treating tuberculosis
(via sciencedaily.com) Original source Researchers have succeeded in identifying and synthesizing a group of molecules that can act against the cause of tuberculosis in a new way. They describe that the so-called callyaerins act against the infectious disease by employing a fundamentally different mechanism compared to antibiotic agents used to date.
Published Unraveling a key junction underlying muscle contraction
(via sciencedaily.com) Original source Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal kingdom and setting the stage for possible future treatments for muscular disorders.
Published Genes or environment? A new model for understanding disease risk factors
(via sciencedaily.com) Original source Researchers have developed a model that more accurately predicts how genetics and air pollution levels causally influence disease development.
Published Precise genetics: New CRISPR method enables efficient DNA modification
(via sciencedaily.com) Original source A research group has developed a new method that further improves the existing CRISPR/Cas technologies: it allows a more precise and seamless introduction of tags into proteins at the gene level. This technology could significantly improve research on proteins in living organisms and opens up new possibilities for medical research.
Published North Sea oil and gas extraction spikes pollution by 10,000 percent, study finds
(via sciencedaily.com) Original source North Sea oil and gas extraction can cause pollution to spike by more than 10,000 percent within half a kilometer around off-shore sites, a study has found. The research has uncovered the true impact on Britain's seabed life -- with the number of species plummeting nearly 30 percent near platforms.
Published Organic nanozymes have broad applications from food and agriculture to biomedicine
(via sciencedaily.com) Original source Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.
Published Platypus and chicken reveal how chromosomes balance between the sexes
(via sciencedaily.com) Original source Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene regulation.
Published How researchers turn bacteria into cellulose-producing mini-factories
(via sciencedaily.com) Original source Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.
Published Is that glass bottle of OJ better for the planet than a plastic container?
(via sciencedaily.com) Original source Which packaging type for a 12-ounce, single-serve container of orange juice would you choose as the most sustainable option: Aluminum/canned, made with recycled material; Carton, described as biodegradable/compostable; Glass, 100% recyclable; or Plastic, described as biodegradable/compostable? If you were like the U.S. consumers surveyed by food scientists you'd prefer glass and believe it was the most sustainable choice. And you all would be mistaken.
Published MicroRNA study sets stage for crop improvements
(via sciencedaily.com) Original source MicroRNAs can make plants more capable of withstanding drought, salinity, pathogens and more. However, in a recent study scientists showed just how much we didn't know about the intricate processes plants use to produce them.
