Published Researchers develop AI model that predicts the accuracy of protein--DNA binding
(via sciencedaily.com) Original source A new artificial intelligence model can predict how different proteins may bind to DNA.
Published Researchers make breakthrough in understanding species abundance
(via sciencedaily.com) Original source The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.
Published Record-breaking recovery of rocks that originated in Earth's mantle could reveal secrets of planet's history
(via sciencedaily.com) Original source Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component. The rocks will help unravel the mantle's role in the origins of life on Earth, the volcanic activity generated when it melts, and how it drives the global cycles of important elements such as carbon and hydrogen.
Published 3D bioprinting advances research on respiratory viruses
(via sciencedaily.com) Original source Researchers develop a microstructured 'artificial lung' model using bioprinting technology.
Published Microscopy technique 'paves way' for improving understanding of cellular functions
(via sciencedaily.com) Original source Scientists have developed a new way of counting labelled proteins in living cells that could become a standard and valuable tool in the field of biomedical research.
Published How ribosomes in our cells enable protein folding
(via sciencedaily.com) Original source Scientists discovered a role played by ribosomes during the folding of new proteins in cells.
Published Viral defense protein speeds up female stem cell production
(via sciencedaily.com) Original source A viral defense mechanism can be used to accelerate the creation of female stem cell lines in mice. The findings can boost efforts in medical research, drug testing, and regenerative therapies, particularly for women and individuals with two X chromosomes.
Published Do smells prime our gut to fight off infection?
(via sciencedaily.com) Original source In nematodes and humans, mitochondrial stress in the nervous system initiates a whole-body response that is most pronounced in the gut. A recent study showed that in nematodes, the odor of a pathogen triggers the nervous system to broadcast this response to the rest of the organism, prepping mitochondria in intestinal cells to fight a bacterial infection. Humans, too, may be able to sense pathogenic odors that prepare the gut for an infection.
Published Discovering how plants make life-and-death decisions
(via sciencedaily.com) Original source Researchers have discovered two proteins that work in tandem to control an important response to cell stress.
Published Carvings at ancient monument may be world's oldest calendars
(via sciencedaily.com) Original source Markings on a stone pillar at a 12,000 year-old archaeological site in Turkey likely represent the world's oldest solar calendar, created as a memorial to a devastating comet strike, experts suggest.
Published Antarctic-wide survey of plant life to aid conservation efforts
(via sciencedaily.com) Original source The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region. The satellite survey of mosses, lichens and algae across the continent will form a baseline for monitoring how Antarctica's vegetation responds to climate change.
Published Greenland fossil discovery reveals increased risk of sea-level catastrophe
(via sciencedaily.com) Original source Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.
Published How the rising earth in Antarctica will impact future sea level rise
(via sciencedaily.com) Original source The rising earth beneath the Antarctic Ice Sheet will likely become a major factor in future sea level rise, a new study suggests.
Published Discovery of a new population of macrophages promoting lung repair after viral infections
(via sciencedaily.com) Original source Researchers have discovered a new population of macrophages, important innate immune cells that populate the lungs after injury caused by respiratory viruses. These macrophages are instrumental in repairing the pulmonary alveoli. This groundbreaking discovery promises to revolutionize our understanding of the post-infectious immune response and opens the door to new regenerative therapies.
Published Reduction in folate intake linked to healthier aging in animal models
(via sciencedaily.com) Original source Scientists found that decreasing folate intake can support healthier metabolisms in aging animal models, challenging the conventional belief that high folate consumption universally benefits health.
Published Coinfecting viruses impede each other's ability to enter cells
(via sciencedaily.com) Original source The process by which phages -- viruses that infect and replicate within bacteria -- enter cells has been studied for over 50 years. In a new study, researchers have used cutting-edge techniques to look at this process at the level of a single cell.
Published What gave the first molecules their stability?
(via sciencedaily.com) Original source The origins of life remain a major mystery. How were complex molecules able to form and remain intact for prolonged periods without disintegrating? A team has demonstrated a mechanism that could have enabled the first RNA molecules to stabilize in the primordial soup. When two RNA strands combine, their stability and lifespan increase significantly.
Published Genetic signatures of domestication identified in pigs, chickens
(via sciencedaily.com) Original source Wild boars and red junglefowl gave rise to common pigs and chickens. These animals' genes evolved to express themselves differently, leading to signatures of domestication -- such as weaker bones and better viral resistance -- in pigs and chickens, according to a research team.
Published Precise package delivery in cells?
(via sciencedaily.com) Original source Researchers have developed new real-time microscopy technology and successfully observed the behavior of 'motor proteins', which may hold the key to unraveling the efficient material transport strategy of cells.
Published Breakthrough in plant disease: New enzyme could lead to anti-bacterial pesticides
(via sciencedaily.com) Original source Scientists uncover a pivotal enzyme, XccOpgD, and its critical role in synthesizing C G16, a key compound used by Xanthomonas pathogens to enhance their virulence against plants. This breakthrough opens new avenues for developing targeted pesticides that combat plant diseases without harming beneficial organisms. Insights into XccOpgD's enzymatic mechanism and optimal conditions offer promising prospects for sustainable agriculture, bolstering crop resilience and global food security while minimizing environmental impact.
