Published Simulation provides images from the carbon nucleus
(via sciencedaily.com) Original source What does the inside of a carbon atom's nucleus look like? A new study provides a comprehensive answer to this question. In the study, the researchers simulated all known energy states of the nucleus. These include the puzzling Hoyle state. If it did not exist, carbon and oxygen would only be present in the universe in tiny traces. Ultimately, we therefore also owe it our own existence.
Published Most species, including humans, who experience early life adversity suffer as adults. How are gorillas different?
(via sciencedaily.com) Original source There's something most species -- from baboons to humans to horses -- have in common: When they suffer serious adversity early in life, they're more likely to experience hardship later on in life.
Published Butterfly tree of life reveals an origin in North America
(via sciencedaily.com) Original source Scientists have discovered where butterflies originated and which plants the first butterflies relied on for food. To reach these conclusions, researchers created the world's largest butterfly tree of life, which they used as a guide to trace trace the evolution of butterflies through time in a four-dimensional puzzle that led back to North and Central America.
Published Researcher uses mammal DNA to zoom into the human genome with unprecedented resolution
(via sciencedaily.com) Original source Scientists have precisely identified base pairs of the human genome that remained consistent over millions of years of mammalian evolution, and which play a crucial role in human disease. The team analyzed the genomes of 240 mammals, including humans and identified base pairs that were 'constrained' -- meaning they remained generally consistent -- across mammal species over the course of evolution. The most constrained base pairs in mammals were over seven times more likely to be causal for human disease and complex trait, and over 11 times more likely when researchers looked at the most constrained base pairs in primates alone.
Published A look inside stem cells helps create personalized regenerative medicine
(via sciencedaily.com) Original source Researchers have examined a specific type of stem cell with an intracellular toolkit to determine which cells are most likely to create effective cell therapies.
Published Brain-belly connection: Gut health may influence likelihood of developing Alzheimer's
(via sciencedaily.com) Original source A new study pinpoints 10 bacterial groups associated with Alzheimer's disease, provides new insights into the relationship between gut makeup and dementia.
Published Singing humpback whales respond to wind noise, but not boats
(via sciencedaily.com) Original source A new study has found humpback whales sing louder when the wind is noisy, but don't have the same reaction to boat engines.
Published Ancestral mitoviruses discovered in mycorrhizal fungi
(via sciencedaily.com) Original source A new group of mitochondrial viruses confined to the arbuscular mycorrhizal fungi Glomeromycotina may represent an ancestral lineage of mitoviruses.
Published Traditional medicine plant could combat drug-resistant malaria
(via sciencedaily.com) Original source Much of what is now considered modern medicine originated as folk remedies or traditional, Indigenous practices. These customs are still alive today, and they could help address a variety of conditions. Now, researchers have identified compounds in the leaves of a particular medicinal Labrador tea plant used throughout the First Nations of Nunavik, Canada, and demonstrated that one of them has activity against the parasite responsible for malaria.
Published Bacteria: Radioactive elements replace essential rare earth metals
(via sciencedaily.com) Original source Bacteria can use certain radioactive elements to sustain their metabolism.
Published New research could help breed for less 'spooky' horses
(via sciencedaily.com) Original source Researchers are working to identify genes that influence horses' tendency to react to perceived danger.
Published How bacteria evolve resistance to antibiotics
(via sciencedaily.com) Original source Bacteria can rapidly evolve resistance to antibiotics by adapting special pumps to flush them out of their cells, according to new research. Antimicrobial resistance is a growing problem of global significance. The rise of resistant 'superbugs' threatens our ability to use antimicrobials like antibiotics to treat and prevent the spread of infections caused by microorganisms. It is hoped that the findings will improve how antibiotics are used to help prevent further spread of antimicrobial resistance.
Published With new experimental method, researchers probe spin structure in 2D materials for first time
(via sciencedaily.com) Original source In the study, a team of researchers describe what they believe to be the first measurement showing direct interaction between electrons spinning in a 2D material and photons coming from microwave radiation.
Published Researcher uses artificial intelligence to discover new materials for advanced computing
(via sciencedaily.com) Original source Researchers have identified novel van der Waals (vdW) magnets using cutting-edge tools in artificial intelligence (AI). In particular, the team identified transition metal halide vdW materials with large magnetic moments that are predicted to be chemically stable using semi-supervised learning. These two-dimensional (2D) vdW magnets have potential applications in data storage, spintronics, and even quantum computing.
Published Human ancestors preferred mosaic landscapes and high ecosystem diversity
(via sciencedaily.com) Original source A new study finds that early human species adapted to mosaic landscapes and diverse food resources, which would have increased our ancestor's resilience to past shifts in climate.
Published Hammerhead sharks hold their breath on deep water hunts to stay warm
(via sciencedaily.com) Original source Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.
Published Physicists discover 'stacked pancakes of liquid magnetism'
(via sciencedaily.com) Original source Physicists have discovered stacked pancakes of 'liquid' magnetism that may account for the strange electronic behavior of some layered helical magnets.
Published Quantum electrodynamics verified with exotic atoms
(via sciencedaily.com) Original source Adapting a detector developed for space X-ray observation, researchers have successfully verify strong-field quantum electrodynamics with exotic atoms.
Published New study reveals boreal wetlands are a large source of reactive vapors in a warming climate
(via sciencedaily.com) Original source Boreal wetlands are a significant source of isoprene and terpenes, a class of highly reactive organic compounds that have a substantial impact on the Earth's climate, according to a new study.
Published Invading insect could transform Antarctic soils
(via sciencedaily.com) Original source A tiny flightless midge which has colonized Antarctica's Signy Island is driving fundamental changes to the island's soil ecosystem, a study shows.
