Published Research shows that 'softer' proteins can cross into the nucleus quicker
(via sciencedaily.com) Original source Researchers have discovered that how soft or rigid proteins are in certain regions can dictate how fast or slow they enter the nucleus.
Published Cellular activity hints that recycling is in our DNA
(via sciencedaily.com) Original source Introns are perhaps one of our genome's biggest mysteries. They are DNA sequences that interrupt the sensible protein-coding information in your genes, and need to be 'spliced out.'
Published Scientists unlock key to breeding 'carbon gobbling' plants with a major appetite
(via sciencedaily.com) Original source The discovery of how a critical enzyme 'hidden in nature's blueprint' works sheds new light on how cells control key processes in carbon fixation, a process fundamental for life on Earth. The discovery could help engineer climate resilient crops capable of sucking carbon dioxide from the atmosphere more efficiently, helping to produce more food in the process.
Published New light shed on carboxysomes in key discovery that could boost photosynthesis
(via sciencedaily.com) Original source A research team has discovered how carboxysomes, carbon-fixing structures found in some bacteria and algae, work. The breakthrough could help scientists redesign and repurpose the structures to enable plants to convert sunlight into more energy, paving the way for improved photosynthesis efficiency, potentially increasing the global food supply and mitigating global warming.
Published Ocean biodiversity work needs improvement
(via sciencedaily.com) Original source An international collaboration says the world's largest marine protected areas aren't collectively delivering the biodiversity benefits they could be because of slow implementation of management strategies and a failure to restrict the most impactful human activities.
Published New sex-determining mechanism in African butterfly discovered
(via sciencedaily.com) Original source In a study of a species of African butterfly, researchers have discovered a previously undescribed molecular mechanism of how the sex of an embryo is initially specified.
Published Rapid oyster reef restoration gives hope for repairing the sea
(via sciencedaily.com) Original source After a century of functional extinction on the Australian mainland, a Flat oyster reef has been successfully restored along a metropolitan Adelaide coastline.
Published New record holder for smallest dispersers of ingested seeds: Woodlice
(via sciencedaily.com) Original source Even bugs as small as woodlice can disperse seeds they eat, setting a new record for smallest animal recorded to do so. The discovery underscores the crucial yet often overlooked role that small invertebrates play in ecosystems.
Published Scientists find ancient, endangered lamprey fish in Queensland, 1400 km north of its previous known range
(via sciencedaily.com) Original source Scientists have confirmed the identity of an unusual, ancient and Endangered species of fish that is living in the coastal rivers of Queensland, about 1400 km north of where it was previously known to live.
Published Acceptance of animals in urban environments
(via sciencedaily.com) Original source How do city residents feel about animals in their immediate surroundings? A recent study shows how different the acceptance of various wild animals in urban areas is. Important factors are the places where the animals are found and their level of popularity -- squirrels and ladybugs come out on top here. The results have important implications for urban planning and nature conservation.
Published Limited adaptability makes freshwater bacteria vulnerable to climate change
(via sciencedaily.com) Original source Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from European lakes, researchers uncovered specific evolutionary strategies that shape these bacteria's lifestyles. Understanding the evolutionary dynamics of aquatic microbial communities is key to safeguarding ecosystem services.
Published Fruit fly model identifies key regulators behind organ development
(via sciencedaily.com) Original source A new computational model simulating fruit fly wing development has enabled researchers to identify previously hidden mechanisms behind organ generation. An research team developed a fruit fly model to reverse engineer the mechanisms that generate organ tissue.
Published Progression of herpesvirus infection remodels mitochondrial organization and metabolism
(via sciencedaily.com) Original source Researchers have found that herpesvirus infection modifies the structure and normal function of the mitochondria in the host cell. The new information will help to understand the interaction between herpesvirus and host cells. Knowledge can be utilized in the development of viral treatments.
Published How a 'conductor' makes sense of chaos in early mouse embryos
(via sciencedaily.com) Original source The earliest stages of mammalian embryo development are like an orchestra performance, where everyone must play at the exact right moment and in perfect harmony. New research identifies one of the conductors making sense of the chaos.
Published Free-forming organelles help plants adapt to climate change
(via sciencedaily.com) Original source Plants' ability to sense light and temperature, and their ability to adapt to climate change, hinges on free-forming structures in their cells whose function was, until now, a mystery. Researchers have now determined how these structures work on a molecular level, as well as where and how they form.
Published High-pressure spectroscopy: Why 3,000 bars are needed to take a comprehensive look at a protein
(via sciencedaily.com) Original source Why 3,000 bars are needed to take a comprehensive look at a protein: Researchers present a new high-pressure spectroscopy method to unravel the properties of proteins' native structures.
Published Aligned peptide 'noodles' could enable lab-grown biological tissues
(via sciencedaily.com) Original source Researchers have developed peptide-based hydrogels that mimic the aligned structure of muscle and nerve tissues, which could enable the development of functional lab-grown tissue.
Published Genomes of 'star algae' shed light on origin of plants
(via sciencedaily.com) Original source Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms. All of these magnificent forms burst forth from a one-off evolutionary event: when plants conquered Earth's surface, known as plant terrestrialization.
Published How E. coli get the power to cause urinary tract infections
(via sciencedaily.com) Original source New research examines how the bacteria Escherichia coli, or E. coli -- responsible for most UTIs -- is able to use host nutrients to reproduce at an extraordinarily rapid pace during infection despite the near sterile environment of fresh urine.
Published Plants utilize drought stress hormone to block snacking spider mites
(via sciencedaily.com) Original source Recent findings that plants employ a drought-survival mechanism to also defend against nutrient-sucking pests could inform future crop breeding programs aimed at achieving better broadscale pest control.
