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 Exercising during pregnancy normalizes eating behaviors in offspring from obese mice
(via sciencedaily.com) Original source Maternal obesity impacts the eating behaviors of offspring via long-term overexpression of the microRNA miR-505-5p, according to a new study.
Published Rocky shores of Pacific Northwest show low resilience to changes in climate
(via sciencedaily.com) Original source A 15-year period ending in 2020 that included a marine heat wave and a sea star wasting disease epidemic saw major changes in the groups of organisms that live along the rocky shores of the Pacific Northwest.
Published Some countries could meet their total electricity needs from floating solar panels
(via sciencedaily.com) Original source Floating solar photovoltaic panels could supply all the electricity needs of some countries, new research has shown. The researchers calculated the daily electrical output for floating photovoltaics (FPV) on nearly 68,000 lakes and reservoirs around the world, using available climate data for each location.
Published Mapping the seafloor sediment superhighway
(via sciencedaily.com) Original source A new scientific model is giving researchers an unprecedented, global look at the activities of clams, worms, and other invertebrate animals that burrow at the bottom of the ocean.
Published Urgent need for action now for increasing threat from invasive alien species
(via sciencedaily.com) Original source Urgent action now is needed to tackle the major and growing global issue of invasive alien species, says a team of 88 experts from 47 countries. The paper follows the (IPBES) thematic assessment report on invasive alien species and their control. The experts say co-developing management actions with multiple stakeholders including government and private sector stakeholders, and Indigenous Peoples and local communities will be critical to achieving success in addressing biological invasions.
Published Researchers call for return of Sumas Lake following devastating 2021 floods
(via sciencedaily.com) Original source A new proposal has emerged in response to the November 2021 floods that swept Sumas Prairie in the Fraser Valley, British Columbia, causing mass evacuations and millions in damages. Instead of rebuilding the dykes to manage water flows and prevent future floods, scientists, along with members of the Sumas First Nation and other research partners, suggest an alternative: let Sumas Lake, which was drained in the early 1920s and converted into the farmland known as Sumas Prairie, return to its natural state. This can be done by buying out properties on the lakebed -- a solution that is projected to cost around $1 billion, less than half of the estimated $2.4 billion cost of repairing the dykes and installing a new pump station.
Published Paving the way for hydrogen from algae enzymes
(via sciencedaily.com) Original source Under certain conditions, some algae are able to produce hydrogen -- a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present. Researchers have identified how such a cofactor, the so-called hydrogen cluster, is assembled. Specifically, they describe the previously unexplained role of the enzyme HydF, which is involved in the final steps of assembly.
Published The world's most powerful anti-fungal chemistries cause fungal pathogens to self-destruct
(via sciencedaily.com) Original source Scientists have discovered that the most widely-used class of antifungals in the world cause pathogens to self-destruct. The research could help improve ways to protect food security and human lives.
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.
Published People are altering decomposition rates in waterways
(via sciencedaily.com) Original source Humans may be accelerating the rate at which organic matter decomposes in rivers and streams on a global scale, according to a new study. That could pose a threat to biodiversity in waterways around the world and increase the amount of carbon in Earth's atmosphere, potentially exacerbating climate change. The study is the first to combine a global experiment and predictive modeling to illustrate how human impacts to waterways may contribute to the global climate crisis.
Published New, modified CRISPR protein can fit inside virus used for gene therapy
(via sciencedaily.com) Original source Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells.
Published Antibiotic pollution disrupts the gut microbiome and blocks memory in aquatic snails
(via sciencedaily.com) Original source Antibiotics prevent snails from forming new memories by disrupting their gut microbiome -- the community of beneficial bacteria found in their guts.
Published Researchers apply quantum computing methods to protein structure prediction
(via sciencedaily.com) Original source Researchers recently published findings that could lay the groundwork for applying quantum computing methods to protein structure prediction.
Published hnRNPM, a guardian of the integrity of cellular protein production
(via sciencedaily.com) Original source Researchers have discovered that the protein hnRNPM prevents the cell from making mistakes while it is producing new proteins, which helps maintain the integrity of this vital process.
Published Editing without 'cutting': Molecular mechanisms of new gene-editing tool revealed
(via sciencedaily.com) Original source New research has determined the spatial structure of various processes of a novel gene-editing tool called 'prime editor.' Functional analysis based on these structures also revealed how a 'prime editor' could achieve reverse transcription, synthesizing DNA from RNA, without 'cutting' both strands of the double helix. Clarifying these molecular mechanisms contributes greatly to designing gene-editing tools accurate enough for gene therapy treatments.
Published Chicken feathers to deliver chemotherapy drugs and repair enzymes
(via sciencedaily.com) Original source A new method of drug delivery using proline, an amino acid found in chicken feathers and skin tissue, could be used to limit the side effects of chemotherapy and repair important enzymes, new research suggests.
Published Some species may tolerate climate change better than expected
(via sciencedaily.com) Original source A new model reassesses the proportion of terrestrial and marine species threatened with extinction by climate change. While the forecasts of traditional models estimate that the diversity of terrestrial species in tropical areas could decrease by 54% between now and 2041-2060, this model is more moderate, predicting a decrease of 39%. Nevertheless, this proportion remains alarming and confirms the importance of taking urgent measures to mitigate climate change and its impact on biodiversity.
Published Marine Protected Areas don't line up with core habitats of rare migratory fish, finds new research
(via sciencedaily.com) Original source 62% of Marine Protected Areas (MPAs) designated to protect rare migratory fish species are outside of their core habitats, according to a new modeling study.
Published Intermittent fasting shows promise in improving gut health, weight management
(via sciencedaily.com) Original source Participants following an intermittent fasting and protein-pacing regimen, which involves evenly spaced protein intake throughout the day, saw better gut health, weight loss and metabolic responses. These benefits were notably greater than those seen with simple calorie restriction. The findings could advance our understanding of the relationship between the gut microbiome and metabolism and improve strategies for managing obesity.
