Published New system triggers cellular waste disposal
(via sciencedaily.com) Original source Established treatments for cancer and other diseases often focus on inhibiting harmful enzymes to mitigate their effects. However, a more innovative approach has emerged: harnessing the cell's natural waste disposal system not just to deactivate but to entirely eradicate these proteins. Researchers have previously demonstrated the efficacy of this approach through two distinct methods. Now they unveil a third system capable of targeting and disposing of previously inaccessible proteins.
Published 'The future is fungal': New research finds that fungi that live in healthy plants are sensitive to climate change
(via sciencedaily.com) Original source Findings more than a decade in the making reveal a rich diversity of beneficial fungi living in boreal forest trees, with implications for the health of forests.
Published Bridging diet, microbes, and metabolism: Implications for metabolic disorders
(via sciencedaily.com) Original source Mounting evidence suggests that the secret to understanding human health and combating metabolic diseases lies hidden within the microscopic world of our gut bacteria. Recent research reveals that a specific fatty acid produced by gut bacteria directly influences fat metabolism in animals. This research is pivotal as it sheds light on the complex interplay between the diet, gut microbiota, and host metabolic health, offering insights that could open new avenues in our approach to managing metabolic disorders.
Published Photosynthetic mechanism of purple sulfur bacterium adapted to low-calcium environments
(via sciencedaily.com) Original source Purple sulfur bacteria (PSB) convert light energy into chemical energy through photosynthesis. Interestingly, certain species can photosynthesize even in environments with low-calcium levels. Using cryo-electron microscopy, researchers unveiled the structure of light-harvesting complexes and elucidated the mechanism that facilitates photosynthesis under low-calcium conditions.
Published Researchers are using RNA in a new approach to fight HIV
(via sciencedaily.com) Original source A pharmacy associate professor has developed a novel nanomedicine loaded with genetic material called small interfering RNAs (siRNA) to fight human immunodeficiency virus (HIV) using gene therapy.
Published Scientists may have cracked the 'aging process' in species
(via sciencedaily.com) Original source Research shows the relationship between a species' age and its risk of going extinct could be accurately predicted by an ecological model called the 'neutral theory of biodiversity.'
Published First-ever report of nesting of incredibly rare and endangered giant turtle
(via sciencedaily.com) Original source Knowledge from local communities has resulted in the first-ever nesting evidence and discovery of a breeding population of an incredibly rare turtle in India.
Published Pollinator's death trap turns into nursery
(via sciencedaily.com) Original source In a group of plants that is famous for luring its pollinators into a death trap, one species offers its flowers as a nursery in exchange. The discovery blurs the line between mutualism and parasitism and sheds light on the evolution of complex plant-insect interactions.
Published Eating too much protein is bad for your arteries, and this amino acid is to blame
(via sciencedaily.com) Original source Consuming over 22% of dietary calories from protein can lead to increased activation of immune cells that play a role in atherosclerotic plaque formation and drive the disease risk, new study showed.
Published Toxoplasmosis: Evolution of infection machinery
(via sciencedaily.com) Original source Researchers have identified a protein that evolved concurrently with the emergence of cellular compartments crucial for the multiplication of the toxoplasmosis pathogen.
Published Online digital data and AI for monitoring biodiversity
(via sciencedaily.com) Original source Researchers propose a framework for integrating online digital data into biodiversity monitoring.
Published Asexual propagation of crop plants gets closer
(via sciencedaily.com) Original source When the female gametes in plants become fertilized, a signal from the sperm activates cell division, leading to the formation of new plant seeds. This activation can also be deliberately triggered without fertilization, as researchers have shown. Their findings open up new avenues for the asexual propagation of crop plants.
Published Root microbes may be the secret to a better tasting cup of tea
(via sciencedaily.com) Original source You'd think the complex flavor in a quality cup of tea would depend mainly on the tea varieties used to make it. But a new study shows that the making of a delicious cup of tea depends on another key ingredient: the collection of microbes found on tea roots. By altering that assemblage, the authors showed that they could make good-quality tea even better.
Published Ancient retroviruses played a key role in the evolution of vertebrate brains
(via sciencedaily.com) Original source Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is essential for myelin production in mammals, amphibians, and fish. The gene sequence, which they dubbed 'RetroMyelin,' is likely a result of ancient viral infection, and comparisons of RetroMyelin in mammals, amphibians, and fish suggest that retroviral infection and genome-invasion events occurred separately in each of these groups.
Published Scientists are unravelling the secrets of red and grey squirrel competition
(via sciencedaily.com) Original source Researchers have identified significant differences between the diversity of gut bacteria in grey squirrels compared to red squirrels which could hold the key to further understanding the ability of grey squirrels to outcompete red squirrels in the UK.
Published Team creates novel rabies viral vectors for neural circuit mapping
(via sciencedaily.com) Original source A research team has created 20 new recombinant rabies viral vectors for neural circuit mapping that offer a range of significant advantages over existing tools, including the ability to detect microstructural changes in models of aging and Alzheimer's disease brain neurons.
Published Key genes linked to DNA damage and human disease uncovered
(via sciencedaily.com) Original source Scientists unveil 145 genes vital for genome health, and possible strategies to curb progression of human genomic disorders.
Published Researchers uncover mechanisms behind enigmatic shapes of nuclei
(via sciencedaily.com) Original source White blood cells known as neutrophils feature a nucleus that is structured strikingly different than most nuclei. These unique shapes permit neutrophils to travel all over the body to combat invading pathogens. Scientists have now deciphered the shapeshifting puzzle of the neutrophil nucleus.
Published Love songs lead scientists to new populations of skywalker gibbons in Myanmar
(via sciencedaily.com) Original source The love songs of the Skywalker gibbon alerted scientists to a new population of the endangered primate in Myanmar.
Published By growing animal cells in rice grains, scientists dish up hybrid food
(via sciencedaily.com) Original source From lab-grown chicken to cricket-derived protein, these innovative alternatives offer hope for a planet struggling with the environmental and ethical impacts of industrial agriculture. Now, scientists add a new recipe to the list -- cultured beef rice -- by growing animal muscle and fat cells inside rice grains. The method results in a nutritious and flavorful hybrid food that, once commercialized, could offer a more affordable protein alternative with a smaller carbon footprint.
