Published Newborn piglets serve as a model for studying influenza
(via sciencedaily.com) Original source Although prevention and treatment strategies are available for influenza, they are not sufficient for vulnerable populations such as young children and newborns. A team of researchers has studied newborn piglets to better understand the progression of influenza infections.
Published Engineers measure pH in cell condensates
(via sciencedaily.com) Original source In a first for the condensate field, researchers have figured out how nucleolar sub-structures are assembled. This organization gives rise to unique pH profiles within nucleoli, which they measured and compared with the pH of nearby non-nucleolar condensates including nuclear speckles and Cajal bodies.
Published 'Noisy' roundworm brains give rise to individuality
(via sciencedaily.com) Original source Research has demonstrated individual differences in and successfully extracted commonalities from the whole-brain activity of roundworms. The researchers also found that computer simulations based on the whole-brain activity of roundworms more accurately reflect real-brain activity when they include so-called 'noise,' or probabilistic elements.
Published Gut bacteria make neurotransmitters to shape the newborn immune system
(via sciencedaily.com) Original source Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early development.
Published Even inactive smokers are densely colonized by microbial communities
(via sciencedaily.com) Original source Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.
Published Protein fragments ID two new 'extremophile' microbes--and may help find alien life
(via sciencedaily.com) Original source Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.
Published Infections from these bacteria are on the rise: New blood test cuts diagnosis time from months to hours
(via sciencedaily.com) Original source Researchers have designed a platform to perform blood-based diagnoses of nontuberculosis mycobacteria, simplifying and shortening a long-complicated procedure from 6 months to 2 hours. Rapid, accurate diagnosis has never been more important as cases of NTM infections have continued to increase annually, spreading from subtropical regions to more temperate zones in part due to global climate change.
Published New study on mating behaviors offers clues into the evolution of attraction
(via sciencedaily.com) Original source In examining the mating rituals of roundworms, researchers uncovered a unique approach to reproduction that maximizes genetic fitness.
Published Dog-killing flatworm discovered in Southern California
(via sciencedaily.com) Original source Scientists have confirmed that a potentially fatal dog parasite is present in a portion of the Colorado River that runs through California.
Published Gut bacteria important for overcoming milk allergy
(via sciencedaily.com) Original source Researchers have discovered a link between gut bacteria and the success of milk-allergy oral immunotherapy. The study found that Bifidobacterium -- a genus of beneficial bacteria in the gut -- was associated with a higher chance of successful treatment. The finding may help in the development of more effective oral immunotherapies, perhaps by combining them with probiotic supplements.
Published It's hearty, it's meaty, it's mold
(via sciencedaily.com) Original source Scientists are exploring how tuning the genomes of mushrooms and molds can transform these food sources into gourmet, nutrient-packed meals made with minimal processing and a light environmental footprint.
Published Alzheimer's drug fermented with help from AI and bacteria moves closer to reality
(via sciencedaily.com) Original source Researchers combined artificial intelligence and chemical biosensors to ferment the precursor of an Alzheimer's drug in bacteria.
Published New bioengineered protein design shows promise in fighting COVID-19
(via sciencedaily.com) Original source A recent scientific breakthrough has emerged from the work of researchers aiming to combat SARS-CoV-2, the virus responsible for COVID-19. The study focuses on the design and development of a novel protein capable of binding to the spike proteins found on the surface of the coronavirus. The goal behind this innovative approach is twofold: first, to identify and recognize the virus for diagnostic purposes, and second, to hinder its ability to infect human cells.
Published New simpler and cost-effective forensics test helps identify touch DNA
(via sciencedaily.com) Original source Research has found a less expensive and easier to use test to learn more about forensic touch DNA. This research has important implications for forensic investigations and being able to identify DNA from a primary contact -- someone who may have committed the crime -- as well as secondary DNA that was inadvertently and indirectly transferred through touch.
Published Sulfur and the origin of life
(via sciencedaily.com) Original source A new study shines a spotlight on sulfur, a chemical element that, while all familiar, has proved surprisingly resistant to scientific efforts in probing its role in the origin of life.
Published Tryptophan in diet, gut bacteria protect against E. coli infection
(via sciencedaily.com) Original source Gut bacteria and a diet rich in the amino acid tryptophan can play a protective role against pathogenic E. coli, which can cause severe stomach upset, cramps, fever, intestinal bleeding and renal failure.
Published Study shows important role gut microbes play in airway health in persons with cystic fibrosis
(via sciencedaily.com) Original source Findings from a new study reflect the important role that the gut microbiome (communities of bacteria) plays in the airway health of persons with cystic fibrosis.
Published Steroid drugs used for HRT can combat E. coli and MRSA
(via sciencedaily.com) Original source Researchers have combined computational and microbiology laboratory approaches to identify existing drugs that can be repurposed to combat antibiotic-resistant bacterial infections. This research has revealed that a class of steroid drugs currently used in hormone replacement therapy (HRT) can also stop the growth of antibiotic-resistant E. coli and effectively kill MRSA.
Published Simple trick could improve accuracy of plant genetics research
(via sciencedaily.com) Original source Researchers have published a simple trick that improves the accuracy of techniques that help us understand how external variables -- such as temperature -- affect gene activity in plants.
Published Milk to the rescue for diabetics? Cow produces human insulin in milk
(via sciencedaily.com) Original source An unassuming brown bovine from the south of Brazil has made history as the first transgenic cow capable of producing human insulin in her milk. The advancement could herald a new era in insulin production, one day eliminating drug scarcity and high costs for people living with diabetes.
