Published Video analysis of Iceland 2010 eruption could improve volcanic ash forecasts for aviation safety
(via sciencedaily.com) Original source Video footage of Iceland's 2010 Eyjafjallaj kull eruption is providing researchers with rare, up-close observations of volcanic ash clouds -- information that could help better forecast how far explosive eruptions disperse their hazardous ash particles.
Published Public more confident connecting increasing heat, wildfires with climate change than other extreme weather events, study finds
(via sciencedaily.com) Original source Researchers found that U.S. adults are fairly confident in linking wildfires and heat to climate change, but less confident when it comes to other extreme weather events like hurricanes, flooding or tornadoes.
Published Quantum data assimilation: A quantum leap in weather prediction
(via sciencedaily.com) Original source Data assimilation is an important mathematical discipline in earth sciences, particularly in numerical weather prediction (NWP). However, conventional data assimilation methods require significant computational resources. To address this, researchers developed a novel method to solve data assimilation on quantum computers, significantly reducing the computation time. The findings of the study have the potential to advance NWP systems and will inspire practical applications of quantum computers for advancing data assimilation.
Published Are plants intelligent? It depends on the definition
(via sciencedaily.com) Original source Goldenrod can perceive other plants nearby without ever touching them, by sensing far-red light ratios reflected off leaves. When goldenrod is eaten by herbivores, it adapts its response based on whether or not another plant is nearby. Is this kind of flexible, real-time, adaptive response a sign of intelligence in plants?
Published Virus-like nanoparticles control the multicellular organization and reproduction of host bacteria
(via sciencedaily.com) Original source Researchers have discovered that virus-like nanoparticles can promote the multicellular organization and reproduction of host bacteria. These particles, which are evolutionarily related to phages (viruses that infect bacteria), contain an enzyme that helps shape the multicellular architecture and ultimately enhances morphological differentiation.
Published Algae offer real potential as a renewable electricity source
(via sciencedaily.com) Original source The need to transition away from fossil fuels to more sustainable energy production is critical. That's why a team of researchers is looking at a potential power source that not only produces no carbon emissions but removes carbon as it works: algae.
Published Researchers use 3D visualization to predict, prevent hurricane damage
(via sciencedaily.com) Original source The researchers say 3D visualization of hurricanes and storm surges allows them to understand how flooding will impact coastal communities by allowing them to vividly see how each building and road might be impacted by a given flood.
Published Study estimates that between 1980 and 2020, 135 million premature deaths could be linked to fine particulate matter pollution
(via sciencedaily.com) Original source A study has revealed that fine particulate matter from 1980 to 2020 was associated with approximately 135 million premature deaths globally.
Published Novel Genetic Clock discovers oldest known marine plant
(via sciencedaily.com) Original source An international research team has discovered the oldest known marine plant using a novel genetic clock. This 1400-year-old seagrass clone from the Baltic Sea dates back to the Migration Period. The research project is a significant step towards better understanding and protecting marine ecosystems.
Published A protein that enables smell--and stops cell death
(via sciencedaily.com) Original source While smell plays a considerable role in the social interactions of humans -- for instance, signaling fear or generating closeness -- for ants, it is vitally important. Researchers have found that a key protein named Orco, essential for the function of olfactory cells, is also critical for the cells' survival in ants.
Published Changes Upstream: RIPE team uses CRISPR/Cas9 to alter photosynthesis for the first time
(via sciencedaily.com) Original source Scientists used CRISPR/Cas9 to increase gene expression in rice by changing its upstream regulatory DNA. While other studies have used the technology to knock out or decrease the expression of genes, this study, is an unbiased gene-editing approach to increase gene expression and downstream photosynthetic activity. The approach is more difficult than transgenic breeding, but could potentially preempt regulatory issues by changing DNA already within the plant, allowing the plants to get in the hands of farmers sooner.
Published Earth and space share the same turbulence
(via sciencedaily.com) Original source Researchers have discovered that the turbulence found in the thermosphere -- known as the gateway to space -- and turbulence in the troposphere, here closer to sea level, follow the same physical laws despite having drastically different atmospheric compositions and dynamics.
Published Silkworms help grow better organ-like tissues in labs
(via sciencedaily.com) Original source Biomedical engineers have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used in a kidney organ-on-a-chip platform, the membrane helped tissues grow to recreate the functionality of both healthy and diseased kidneys.
Published Fish out of water: How killifish embryos adapted their development
(via sciencedaily.com) Original source The annual killifish lives in regions with extreme drought. A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body structure is not predetermined from the outset. This could enable the species to survive dry periods unscathed.
Published Myelination in the brain may be key to 'learning' opioid addiction
(via sciencedaily.com) Original source Scientists have found that the process of adaptive myelination, which helps the brain learn new skills, can also promote addiction to opioids.
Published New technique reveals how gene transcription is coordinated in cells
(via sciencedaily.com) Original source Researchers invented a technique that allows them to observe which genes and enhancers are active in a cell at the same time. This could help them determine which enhancers control which genes and may reveal potential new drug targets for genetic disorders.
Published Father's diet before conception influences children's health
(via sciencedaily.com) Original source A recent study provides new insights into how fathers' diets and overweight can affect their children's health even before conception. The findings of the study can help develop preventive health measures for men wishing to become fathers: The healthier the father's diet, the lower the risk for their children to develop obesity or diseases such as diabetes later in life.
Published The embryo assembles itself
(via sciencedaily.com) Original source Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of birds. Interestingly, the mammalian embryo develops similarly. Scientists now introduce a mathematical framework that analyzes self-organization from a single cell to a multicellular organism.
Published New coral disease forecasting system
(via sciencedaily.com) Original source Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.
