[ad_1] Everywhere we look in the natural world, there is evidence of natural selection: the resin armor of a lodgepole pine cone evolved to defend itself against seed-hungry birds and squirrels, or a giraffe’s long neck was evolutionarily favored to reach high vegetation that the competition cannot touch. Natural selection …

[ad_1] An inexpensive FDA-approved drug, cholestyramine, taken in combination with an antibiotic prevents the antibiotic from driving antimicrobial resistance, according to new research by scientists at Penn State and the University of Michigan. The team’s findings appear today (December 1) in the journal eLife. “Antimicrobial resistance is a serious problem …

[ad_1] Infections from Clostridium difficile respond poorly to antibiotic therapy. Stool transplant appears to be an effective therapeutic alternative that significantly reduces recurrence, according to a recent study conducted in the United States. The microbiota intestinal is a community of microorganisms, mainly bacteria – and in a lesser proportion, virus …

[ad_1] Inside each cell, thousands of different proteins from the mechanism that keeps all living things – from humans and plants to microscopic bacteria – alive and well. Almost all diseases, including cancer, dementia, and even infectious diseases such as COVID-19, are related to how these proteins work. Because the …

[ad_1] Hurricanes, pollution, disease, bleaching and the effects of an ever-warming planet all have a negative impact on the health of coral reefs around the world. However, those in the Caribbean are facing a new threat: an aggressive, golden-brown, crust-like algae that is rapidly invading shallow coral reefs. Algae, known …

[ad_1] Antibiotics are used to prevent and treat bacterial infections. They have played an important role in the fight against infectious diseases such as tuberculosis, pneumonia, typhoid fever and meningitis in 20th century. However, the misuse of antibiotics has also led to the development of so-called multi-drug resistance (MDR) whereby …

[ad_1] New research has identified and described a cellular process that, despite what the textbooks say, has remained elusive to scientists until now – precisely as the copy of genetic material that, once initiated, is properly deactivated. The discovery concerns a key process essential to life: the transcription stage of …

[ad_1] Scientists have carried out research that will shed light on the centuries. Researchers at the University of Sheffield and the University of Oxford, studying Pseudomonas aeruginosa, a type of bacterium responsible for deadly lung infections, found that clusters of bacteria spread faster on surfaces when individuals move slowly. According …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 25, 2020 Researchers from Bochum, Göttingen, Duisburg and Cologne have developed a new method for detecting bacteria and infections. They use fluorescent nanosensors to track down pathogens faster and easier than established methods. A team led by Professor Sebastian Kruβ, formerly at the University …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 25, 2020 With new insights into how the CRISPR genetic tool – which allows direct editing of our genes – has evolved and adapted, we are now one step closer to understanding the basics of the constant struggle for survival that takes place in …
