This special issue will provide a global snapshot of the research that addresses the association between #microbiology and #climate change. Guest editors: Dr. Jason Tetro, University of the Pacific, San Francisco Dr. David Ojcius, University of the Pacific, San Francisco Special issue information: #ClimateChange has become part of the common lexicon; however, most discussions tend to focus on macroscopic topics such as atmospheric CO2 levels and extreme weather conditions.

Pink Australian lake gets its color from red & purple microbes. DNA sequencing has revealed that a bright pink lake on an island off Western #Australia gets its color from a mix of salt-loving #bacteria & algae. #microbiology #environment Read more at: https://www.newscientist.com/article/2311507-red-and-purple-microbes-give-australias-mysterious-pink-lake-its-hue/

Researchers found an association between the oral #microbiota and the risk of #hypertension in people who have experienced menopause. Specific bacteria were associated with both baseline blood pressure and the risk of developing hypertension. #oralhealth #heart #heartdisease #microbiology #microbiome Almost half of adults in the United States have high blood pressure, or hypertension. People with hypertension have an increased risk of stroke and heart disease. The researchers

It’s no secret that we rely on our immune systems to fight off common infections. But what you might not know is that the immune system is highly evolved and can even sense danger, explains David Ojcius, the Assistant Dean of Research at University of the Pacific in San Francisco, California. #immunology #microbiology #innateimmunity Read more at: https://davidojcius.com/how-the-immune-system-senses-danger-immunology-researcher-david-ojcius-explains/

#microbiology #LifelongLearning #education #research #biophysics #Pacific #immunology Interview at Thrive Global What do you love most about the industry you are in? The industry I’m in is actually two in one: teaching and research. I love teaching and interacting with students. In many ways I learn as I teach them. I love their enthusiasm and their optimism. The thing about research is you are a student for life. You constantly have to learn new skills. It requires you to be

Scientists identify a bacterial species that resides within Synoicum adareanum (a species of ascidian common to the waters of Antarctica's Anvers Island archipelago) and that produces a melanoma-fighting compound called palmerolide A. #microbiology #environment #symbiosis #bacteriology #cancer There are few places farther from your medicine cabinet than the tissues of an ascidian, or "sea squirt," on the icy Antarctic sea floor—but this is precisely where scientists are looki

#symbiosis #microbiology #plantbiology #agriculture Researchers identified 2 transcription factors that control how much leghemoglobin is made in legume nodules. Leghemoglobin binds to oxygen & is red & gives legume nodules their pink color. Scientists discover the genetics inside legumes that control the production of an oxygen-carrying molecule, crucial to the plant's close relationships with nitrogen-fixing bacteria. The finding offers the potential to give other plants th

Young #microbiome #microbiota #health #microbiology Notre corps abrite une communauté complexe de milliards de microbes, surtout des bactéries, mais aussi des virus, levures et protozoaires, un nombre à peu près équivalent à celui des cellules humaines. Dans des conditions normales, cette population vit en équilibre avec l’organisme et joue plusieurs rôles physiologiques importants pour notre san

A new realm of “precision fermentation” beckons #microbiology #food #fermentation The fetid salinity of prosciutto, bresaola’s jaw-wearying toughness and the pallid greasiness of lardo, which is cured solid fat, all have their fans—if not, normally, among those in the business of keeping arteries clean. But the single best cured meat in the world comes from north-eastern Thailand. Rice, pork, garlic, salt and herbs are stuffed into a casing and left at room temperature for a

Study reveals extended lifespan of starved bacteria. "How bacteria survive long periods of energy limitation is relevant to understanding chronic infections in humans and other hosts, and is related to how some pathogens tolerate drugs like #antibiotics." #microbiology #bacteriology #AntiobiticResistance A study of microbial populations under a prolonged period of starvation by Indiana University professor Jay T. Lennon and his laboratory could help researchers answer questio

New Study Shows #ClimateChange May Increase the Spread of Plant Pathogens #climate #microbiology Models suggest that higher latitude crops will experience higher infection rates and a greater number of threats The agricultural impact of climate change would be a little more straightforward, if it occurred in a world where crops were free of their microbes. Research published today has found that in this hypothetical landscape, rising global temperatures will boost global agri

The science behind the idea of restoring the intestinal #microbiome to an ancestral state is shaky, skeptics say, and in some cases unethical. #microbiology #microbiota As the sun set in Tanzania on a September evening in 2014, Jeff Leach inserted a turkey baster filled with another man’s feces into his rectum and squeezed the bulb. The feces, he said, came from a hunter-gatherer who was a member of the Hadza people and lived nearby. Mr. Leach said he was trying to “rewild” h

After controlling for high levels of bacterial contamination in their lab and reagents, researchers detect microbial genetic material in plasma samples from healthy people and #cancer patients. #microbiology #immunology #DNA Most biomarkers that clinicians use to diagnose cancer are human. But growing evidence for a link between the microbiome and malignancy presents an opportunity to look at the presence of microbial DNA as a way to identify and possibly predict disease. In

Symbionts sans frontieres: Bacterial partners travel the world #symbiosis #microbiology #environment This pandemic year has restricted international travel for humans. Not so for some microscopic bacteria in the ocean: They partner up with clams living in the sand beneath the shimmering waters of coastal habitats throughout the globe. According to research by scientists from the Max Planck Institute for Marine Microbiology in Bremen and the University of Vienna now published

Researchers show that a slicing mechanism facilitates host entry by the plant-pathogen #Phytophthora. #microbiology #potatoes #plants In the 19th century, the notorious pathogen Phytophthora infestans caused a large famine in Ireland and other parts of Western Europe. To this day, it continues to pose a major threat to global food production. It has long been a mystery how this microscopically small organism and other members of the Phytophthora genus mechanically gain entry

What is Salmonellosis? (free video) Salmonellosis is a bacterial infection caused by #Salmonella bacteria, which have 2 species, S. enterica and S. bongori and over 2400 serotypes. #microbiology #bacteriology

What is Staphylococcus aureus? (free video) #Staphylococcus aureus, sometimes called staph aureus, is a gram positive coccus that grows in clusters. It’s a part of the normal skin and nasal flora in about a quarter of the population, but if it overgrows or if the skin is damaged, then it can cause disease through direct colonization, toxin production, or both. #microbiology #bacteriology
