Published Study reveals how pollinators cope with plant toxins
(via sciencedaily.com) Original source Pollinators such as honeybees produce special enzymes that detoxify defence chemicals produced by plants, new research shows.
Published Biologists determine the evolutionary age of individual cell types providing critical insights for animal development
(via sciencedaily.com) Original source A research team has recently made a significant discovery about the evolutionary age of different type of cells in a small animal called Caenorhabditis elegans (C. elegans). By using single-cell transcriptomic data and refined phylostratigraphy, the team determines the transcriptomic age of individual cells, which means they are able to estimate the evolutionary origin of different cells based on the age of the genes expressed in the cells.
Published Oldest bat skeletons ever found described from Wyoming fossils
(via sciencedaily.com) Original source Scientists have described a new species of bat based on the oldest bat skeletons ever recovered. The study on the extinct bat, which lived in Wyoming about 52 million years ago, supports the idea that bats diversified rapidly on multiple continents during this time.
Published Study compares de novo proteins with randomly produced proteins
(via sciencedaily.com) Original source In a series of experiments, a team of researchers have compared de novo proteins with random-sequence proteins, looking at their stability and solubility. The results are set to advance basic research in this new field.
Published How skates learned to fly through water
(via sciencedaily.com) Original source Genes are not the only drivers of evolution. The iconic fins of skates are caused by changes in the non-coding genome and its three-dimensional structure, an international research team reports.
Published How did Earth get its water?
(via sciencedaily.com) Original source Our planet's water could have originated from interactions between the hydrogen-rich atmospheres and magma oceans of the planetary embryos that comprised Earth's formative years.
Published Scientists track evolution of microbes on the skin's surface
(via sciencedaily.com) Original source Researchers have discovered that Staphylococcus aureus can rapidly evolve within a single person's microbiome. They found that in people with eczema, S. aureus tends to evolve to a variant with a mutation in a specific gene that helps it grow faster on the skin.
Published Humans need Earth-like ecosystem for deep-space living
(via sciencedaily.com) Original source Can humans endure long-term living in deep space? The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agriculture and handling waste far from Earth.
Published British flower study reveals surprise about plants' sex life
(via sciencedaily.com) Original source A study of Britain's native flowering plants has led to new insights into the mysterious process that allows wild plants to breed across species -- one of plants' most powerful evolutionary forces. When wild flowering plants are sizing up others they may often end up in a marriage between close relatives rather than neighbors, a new study has revealed.
Published Critical observations of sinking coasts
(via sciencedaily.com) Original source Using satellite-obtained data from 2007-21, researchers mapped the entire East Coast to demonstrate how the inclusion of land subsidence reveals many areas to be more vulnerable to floods and erosion than previously thought.
Published Study re-evaluates hazards and climate impacts of massive underwater volcanic eruptions
(via sciencedaily.com) Original source Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new research.
Published Lightning strike creates phosphorus material
(via sciencedaily.com) Original source A lightning strike in New Port Richey, Florida, led to a chemical reaction creating a new material that is transitional between space minerals and minerals found on Earth. High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.
Published Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards
(via sciencedaily.com) Original source Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.
Published In Florida study, nonnative leaf-litter ants are replacing native ants
(via sciencedaily.com) Original source A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.
Published Woolly mammoths evolved smaller ears and woolier coats over the 700,000 years that they roamed the Siberian steppes
(via sciencedaily.com) Original source A team of researchers compared the genomes of woolly mammoths with modern day elephants to find out what made woolly mammoths unique, both as individuals and as a species. The investigators report that many of the woolly mammoth's trademark features -- including their woolly coats and large fat deposits -- were already genetically encoded in the earliest woolly mammoths, but these and other traits became more defined over the species' 700,000+ year existence. They also identified a gene with several mutations that may have been responsible for the woolly mammoth's miniscule ears.
Published Blind dating in bacteria evolution
(via sciencedaily.com) Original source A team of researchers reconstructed long-extinct proteins of a UV protection system of cyanobacteria. The surprising result: the proteins were already compatible with each other when they first met. This discovery expands the knowledge horizon on the rules of evolution.
Published A cold-specialized icefish species underwent major genetic changes as it migrated to temperate waters
(via sciencedaily.com) Original source Biologists have explored the genetic mechanisms underlying the transition from freezing Antarctic waters to more temperature waters by Antarctic Notothenioid fish.
Published Was plate tectonics occurring when life first formed on Earth?
(via sciencedaily.com) Original source Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely occurring more than 4.2 billion years ago when life is thought to have first formed on our planet. This finding could prove beneficial in the search for life on other planets.
Published A detailed map of the microverse: Microbial niches
(via sciencedaily.com) Original source What defines the habitat -- the ecological niche -- of a microorganism? It is a combination of environmental factors such as temperature, moisture, and nutrient content. But the exact contribution of each of these factors is difficult to predict. A research team has redefined microbial niches by determining which microorganisms live together.
Published Elephants as a new model for understanding human evolution
(via sciencedaily.com) Original source Human culture and language may be the result of 'self-domestication': an evolutionary process that leads to less aggressive and more prosocial individuals. A research team argues that elephants -- like humans and bonobos -- may also be self-domesticated. Elephants show many traits associated with self-domestication, such as prosocial behavior, playfulness and complex communication skills. This makes elephants an interesting new animal model for the evolution of prosociality.
