Published New two-step flu vaccine strategy shows promise in pig model
(via sciencedaily.com) Original source A new, two-step flu vaccination strategy that pairs intramuscular injection of a viral vectored flu vaccine with nasal spray administration of a novel attenuated live flu virus appears to be safe and effective in pigs, researchers report.
Published Bacteria encode hidden genes outside their genome--do we?
(via sciencedaily.com) Original source A 'loopy' discovery in bacteria is raising fundamental questions about the makeup of our own genome -- and revealing a potential wellspring of material for new genetic therapies.
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 Glossy black-cockatoos prefer the fruits of ancient rocks
(via sciencedaily.com) Original source New research has shown that glossy black-cockatoos prefer to feed from trees growing in acidic soils.
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 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 Recurrent wheezing in children linked to 'silent' viral infections
(via sciencedaily.com) Original source Nearly a quarter of children with recurrent wheezing have 'silent' lung infections that would be better treated with antiviral medications than commonly prescribed steroids that can carry lifelong side effects, new research reveals.
Published Asthma emergencies spike when allergenic pollen blooms
(via sciencedaily.com) Original source A new study that tracks how many asthma-related emergency room visits result from pollen in metropolitan areas highlights the importance of knowing local plants and the need for developing science-based pollen forecasts.
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 Cocaine discovery could pave way for treatment for substance abuse
(via sciencedaily.com) Original source Cocaine binds to a specific transporter in the brain that is responsible for regulating dopamine levels. Researchers have studied and described the process, producing new knowledge that may bring us a step closer to designing a drug for cocaine abuse.
Published Bacterial gut diversity improves the athletic performance of racehorses
(via sciencedaily.com) Original source The composition of gut bacteria of Thoroughbred racehorses at one-month-old can predict their future athletic performance, according to a new study. Foals with lower bacterial diversity at 28 days old also had a significantly increased risk of respiratory disease later in life.
Published Nasal microbiome: Depriving multi-resistant 'bugs' of iron
(via sciencedaily.com) Original source Whether dangerous staphylococci survive in the nose depends on what other bacteria are present -- and how they obtain iron.
Published Elephants on the move: Mapping connections across African landscapes
(via sciencedaily.com) Original source Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.
Published Ketogenic Diet may reduce friendly gut bacteria and raise cholesterol levels
(via sciencedaily.com) Original source A study reveals that ketogenic low-carbohydrate diets can increase cholesterol levels and reduce beneficial gut bacteria, specifically Bifidobacterium.
Published Study analyzes potato-pathogen 'arms race' after Irish famine
(via sciencedaily.com) Original source Researchers reveal more about the tit-for-tat evolutionary changes occurring in both potato plants and the pathogen that caused the 1840s Irish potato famine.
Published Why virus causing cold sores does not spread to devastating brain infection
(via sciencedaily.com) Original source A previously unknown defence mechanism in the brain prevents herpesvirus from infecting the brain's nerve cells.
Published Honey added to yogurt supports probiotic cultures for digestive health
(via sciencedaily.com) Original source If you enjoy a bowl of plain yogurt in the morning, adding a spoonful of honey is a delicious way to sweeten your favorite breakfast food. It also supports the probiotic cultures in the popular fermented dairy product, according to two new studies.
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.
