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 Giant viruses found on Greenland ice sheet
(via sciencedaily.com) Original source Giant viruses found on the Greenland ice sheet probably regulate the growth of snow algae on the ice by infecting them. Knowing how to control these viruses could help us reduce the rate of ice-melt.
Published Exploring three frontiers in marine biomass and blue carbon capture
(via sciencedaily.com) Original source A new study offers first-time insights into three emerging climate innovations to safeguard or increase the carbon naturally captured by ocean and coastal ecosystems: rapid interventions to save the Great Barrier Reef, satellite-tracked kelp beds in the deep ocean, and seagrass nurseries in the United Kingdom.
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 Microscopic defects in ice shape how massive glaciers flow, study shows
(via sciencedaily.com) Original source A glacier's flow depends on how microscopic defects move through the ice, according to new research that also yielded a new model for predicting how glaciers will flow, ultimately contributing to sea-level rise.
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 Shape and depth of ocean floor profoundly influence how carbon is stored there
(via sciencedaily.com) Original source The movement of carbon between the atmosphere, oceans and continents -- or carbon cycle -- regulates Earth's climate, with the ocean playing a major role in carbon sequestration. A new study finds that the shape and depth of the ocean floor explain up to 50% of the changes in depth at which carbon has been sequestered there over the past 80 million years. While these changes have been previously attributed to other causes, the new finding could inform ongoing efforts to combat climate change through marine carbon sequestration.
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 Fungus breaks down ocean plastic
(via sciencedaily.com) Original source A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers expect that many more plastic degrading fungi are living in deeper parts of the ocean.
Published Researchers discover 'trojan horse' virus hiding in human parasite
(via sciencedaily.com) Original source An international team has found a new RNA virus that they believe is hitching a ride with a common human parasite. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis disease.
Published Fjords are effective carbon traps regardless of oxygen levels
(via sciencedaily.com) Original source The fjords on Sweden's west coast act as effective carbon traps regardless of whether the bottom water is oxygen-rich or not.
Published Trout in mine-polluted rivers are genetically 'isolated'
(via sciencedaily.com) Original source Trout living in rivers polluted by metal from old mines across the British Isles are genetically 'isolated' from other trout, new research shows.
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 Historic iceberg surges offer insights on modern climate change
(via sciencedaily.com) Original source A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater runoff.
Published Local bright spot among melting glaciers: 2000 km of Antarctic ice-covered coastline has been stable for 85 years
(via sciencedaily.com) Original source A whaler's forgotten aerial photos from 1937 have given researchers the most detailed picture of the ice evolution in East Antarctica to date. The results show that the ice has remained stable and even grown slightly over almost a century, though scientists observe early signs of weakening. The research offers new insights that enhance predictions of ice changes and sea level rise.
Published Researchers expose new symbiosis origin theories, identify experimental systems for plant life
(via sciencedaily.com) Original source Research work on symbiosis -- a mutually beneficial relationship between living organisms -- is pushing back against the newer theory of a 'single-origin' of root nodule symbiosis (RNS) -- that all symbiosis between plant root nodules and nitrogen-fixing bacteria stems from one point--instead suggesting a 'multiple-origin' theory of sybiosis which opens a better understanding for genetically engineering crops.
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.
