A recent study from the University of Washington explores the ways parasitism will respond to climate change, providing researchers new insights into disease transmission. The paper was published May 18 in the journal Trends in Ecology and Evolution.
The most common organism in the world's oceans -- and possibly the whole planet -- harbors a virus in its DNA. This virus may have helped it survive and outcompete other organisms.
A new technique overcomes a serious hurdle in the field of bacterial design and engineering. Researchers develop method to identify proteins that enable highly efficient bacterial design. Approach has potential to boost efforts in bacterial design to tackle infectious diseases, bacterial drug resistance, environmental cleanup and more.
Gut bacterial imbalance is linked with many neurological disorders. Now researchers have identified a common thread: changes in gut mucus. It's a new gut-brain connection that opens fresh paths for scientists searching for ways to treat brain disorders by targeting our 'second brain' - the gut.
Resembling giant mealworms, superworms (Zophobas atratus) are beetle larvae that are often sold in pet stores as feed for reptiles, fish and birds. In addition to their relatively large size (about 2 inches long), these worms have another superpower: They can degrade polystyrene plastic. Now, researchers reporting in ACS' Environmental Science & Technology have linked this ability to a strain of bacteria that lives in the larvae's gut.
The novel coronavirus pandemic has caused an increased demand for antimicrobial treatments that can keep surfaces clean, particularly in health care settings. Although some surfaces have been developed that can combat bacteria, what's been lacking is a surface that can also kill off viruses. Now, researchers have found a way to impart durable antiviral and antibacterial properties to an aluminum alloy used in hospitals, according to a report in ACS Biomaterials Science & Engineering.
The collection of oral bacteria in daily e-cigarette users' mouths is teeming with potent infection-causing organisms that put vapers at substantial risk for ailments ranging from gum disease to cancer, researchers found.
In living cells, enzymes drive biochemical metabolic processes. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers at Münster University (Germany) identified an enzyme that, when illuminated with blue light, initiates a reaction that was previously unknown in enzymatics. The study was published in 'Nature Communications'.
As inevitable fellow travellers on the bodies of astronauts, spaceships, or equipment, terrestrial microorganisms will undoubtedly come into contact with extraterrestrial environments. Researchers from the Radboudumc describe in an article in Astrobiology that bacteria can survive on an 'extraterrestrial diet', which affected their pathogenic potential.
Despite conventional understanding that three Kai proteins are required for the circadian oscillation of cyanobacteria, scientists discovered that even when one of them is destroyed, the oscillation is not completely abolished but instead damped. Further, they found that the damped rhythms resonate with external cycles of approximately 24 hours, which indicates that the natural frequency of the damped oscillation is similar to a circadian clock.
