I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Triggering bacteria in the service of medicine” Chen Zhang, a graduate student in the Mohammad Seyedsayamdost lab, prepares a cell culture within a sterile clean hood. Credit: C. Todd Reichart, Department of Chemistry Bacteria, as it turns out, are a lot like us. They get complacent in relaxed, non-threatening environments. And when they’re relaxed, they don’t produce defenses that guard…
“#Bacteria are always at war. Understanding their use of weapons may lead to antibiotic alternatives” E.coli can cause disease but it also lives in our gut and has a range of toxins that helps keep the populations of the various bacteria in balance.

“#Researchers study myxobacteria’s ability to distinguish self from non-self” Vera Troselj (left) and Christopher Vassallo, both Ph.D. candidates in University of Wyoming Professor Dan Wall’s lab at the time of the research, are co-authors of a paper, titled “Rapid Diversification of Wild Social Groups Driven by Toxin-Immunity Loci on Mobile Genetic Elements,” that was published…
“#Super-resolution microscopy reveals a twist inside of cells” Credit: CC0 Public Domain If you want to understand the underlying mechanisms of cellular motility and division, then the centriole is the organelle of interest. Each cell has a pair of centrioles which help to segregate chromosomes during cell division. These special organelles are multi-molecular machines composed…
“#Mapping microbiomes to improve food quantity, quality and safety” Credit: marekuliasz, Shutterstock Thanks to its key role in development, immunity and nutrition, the microbiome—the genetic material of all microorganisms that live in the human body—has attracted a lot of attention in recent years. The gut microbiome in particular, and how it affects overall health, has…
“#New family of enzymes reveals the Achilles’ heel of fungal pathogens” Dr. Lynne Howell (left) and Dr. Don Sheppard (right) solved the structure of a key enzyme responsible for biofilm formation in the fungal pathogen A. fumigatus. Credit: University of Toronto (Dr. Lynne Howell), McGill University (Dr. Don Sheppard) Aspergillus fumigatus is a species of…
“#Using tiny electrodes to measure electrical activity in bacteria” Bacteria sitting on the gate electrode, viewed by a fluorescence microscope. Credit: Thor Balkhed Scientists at Laboratory of Organic Electronics, Linköping University, have developed an organic electrochemical transistor that they can use to measure and study in fine detail a phenomenon known as extracellular electron transfer…
“#Staph’s activation of blood clotting” Scanning electron microscopic (SEM) image of Staphylococcus aureus bacteria, enmeshed in a human white blood cell. Credit: NIAID Acute bacterial endocarditis—infection of the inner lining of the heart—is most often caused by the bacteria Staphylococcus aureus (“staph”) and has up to a 40% mortality rate. Staph bacteria circulating in the…
“#Water bacteria have a green thumb” Scanning electron microscope image of Stieleria maiorica. Cells in pink. Matrix in blue. Credit: Manfred Rohde/HZI Braunschweig The sheer endless expanses of the oceans are hostile deserts—at least from the perspective of a bacterium living in water. Tiny as it is, its chances of finding sufficient nutrients in the…
“#Clostridioides difficile captures blood cell cofactor to build defensive shield” This photograph depicts Clostridium difficile colonies after 48hrs growth on a blood agar plate; Magnified 4.8X. C. difficile, an anaerobic gram-positive rod, is the most frequently identified cause of antibiotic-associated diarrhea (AAD). It accounts for approximately 15-25% of all episodes of AAD.
