Published Researchers create artificial cells that act like living cells
(via sciencedaily.com) Original source Researchers describe the steps they took to manipulate DNA and proteins -- essential building blocks of life -- to create cells that look and act like cells from the body. This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems and diagnostic tools.
Published Tropical fish are invading Australian ocean water
(via sciencedaily.com) Original source A study of shallow-water fish communities on rocky reefs in south-eastern Australia has found climate change is helping tropical fish species invade temperate Australian waters.
Published The spiciness of mustard may depend on soil microbes
(via sciencedaily.com) Original source New study finds microbes may influence the taste of mustard seeds.
Published AI tool creates 'synthetic' images of cells for enhanced microscopy analysis
(via sciencedaily.com) Original source Researchers have developed a method to use an image generation AI model to create realistic images of single cells, which are then used as 'synthetic data' to train an AI model to better carry out single-cell segmentation.
Published Liquid droplets shape how cells respond to change
(via sciencedaily.com) Original source New research has shown that cells regulate cAMP/PKA signaling by forming liquid droplets that segregate excess PKA catalytic subunits where they can do no harm. Some cancers may block the formation of liquid droplets, leading to hyperactive signaling and tumor formation.
Published AI can improve Alzheimer's treatment through the 'gut-brain axis'
(via sciencedaily.com) Original source Researchers are using artificial intelligence to uncover the link between the gut microbiome and Alzheimer's disease. Previous studies showed that Alzheimer's disease patients have changes in their gut bacteria as the disease develops. The study outlines a computational method to determine how bacterial byproducts called metabolites interact with receptors on cells and contribute to Alzheimer's disease.
Published Scientists discover the cellular functions of a family of proteins integral to inflammatory diseases
(via sciencedaily.com) Original source In a scientific breakthrough, researchers have revealed the biological mechanisms by which a family of proteins known as histone deacetylases (HDACs) activate immune system cells linked to inflammatory bowel disease (IBD) and other inflammatory diseases.
Published Switching off the light to see better
(via sciencedaily.com) Original source Researchers used structured light and switchable fluorescent molecules to reduce the background light from the out-of-plane regions of microscope samples. This method allowed for the acquisition of images that surpassed the conventional resolution limit, and it may be useful for further study of cell clusters and other biological systems.
Published Protein network dynamics during cell division
(via sciencedaily.com) Original source An international team has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the cell cycle, which required a combination of deep learning and high-throughput microscopy.
Published The enemy within: How pathogens spread unrecognized in the body
(via sciencedaily.com) Original source Some pathogens hide inside human cells to enhance their survival. Researchers have uncovered a unique tactic certain bacteria use to spread in the body without being detected by the immune system. In their study, they reveal the crucial role of a bacterial nanomachine in this infection process.
Published Breakthrough rice bran nanoparticles show promise as affordable and targeted anticancer agent
(via sciencedaily.com) Original source Plant-derived nanoparticles have demonstrated significant anticancer effects. Researchers recently developed rice bran-derived nanoparticles (rbNPs) that efficiently suppressed cell proliferation and induced programmed cell death of only cancer cells. Furthermore, rbNPs successfully suppressed the growth of tumors in mice having aggressive adenocarcinoma in their peritoneal cavity, without any adverse effects. Given their low production costs and high efficacy, rbNPs hold great promise for developing affordable and safe anticancer agents.
Published Invasive species sound off about impending ecosystem changes
(via sciencedaily.com) Original source Anticipating changes to ecosystems is often at best an educated guess, but what if there was a way to better tune into possible changes occurring? Researchers have discovered that the silent growth of non-native invasive plants can affect the soundscape of an ecosystem. These altered soundscapes, the acoustic patterns of a landscape through space and time, may provide a key to better observing the hard-to-see physical and biological changes occurring in an ecosystem as they are beginning.
Published New compound from blessed thistle promotes functional nerve regeneration
(via sciencedaily.com) Original source Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers have now found a completely novel use for Cnicin. Animal models as well as human cells have shown that Cnicin significantly accelerates axon (nerve fibers) growth.
Published Lemur's lament: When one vulnerable species stalks another
(via sciencedaily.com) Original source What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.
Published Surf clams off the coast of Virginia reappear -- and rebound
(via sciencedaily.com) Original source The Atlantic surfclam, an economically valuable species that is the main ingredient in clam chowder and fried clam strips, has returned to Virginia waters in a big way, reversing a die-off that started more than two decades ago. In a comprehensive study of surfclams collected from an area about 45 miles due east from the mouth of the Chesapeake Bay, scientists found the population to be thriving and growing.
Published New research defines specific genomic changes associated with the transmissibility of the monkeypox virus
(via sciencedaily.com) Original source Scientists have located and identified alterations in the monkeypox virus genome that potentially correlate with changes in the virus's transmissibility observed in the 2022 outbreak.
Published Key protein regulates immune response to viruses in mammal cells
(via sciencedaily.com) Original source Researchers have revealed the regulatory mechanism of a specific protein, TRBP, that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and nucleic acid medicines to treat genetic disorders.
Published Helping migrating salmon survive mortality hot-spot
(via sciencedaily.com) Original source Researchers used acoustic telemetry to tag and track coho on their journey.
Published Light show in living cells
(via sciencedaily.com) Original source Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge -- especially in living cells, as the required fluorescent labeling had to be individually attached to each protein. The research group has now overcome this hurdle: With a method called 'vpCells,' it is possible to label many proteins simultaneously, using five different fluorescent colors.
Published Why can zebrafish regenerate damaged heart tissue, while other fish species cannot?
(via sciencedaily.com) Original source A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on how zebrafish heal heart tissue by comparing how this species responds to heart injury with medaka, a fish species that cannot regenerate cardiac tissue.
