A research team led by the University of Adelaide has found that revegetation of green spaces within cities can improve soil microbiota diversity towards a more natural, biodiverse state, which has been linked to human health benefits.
Medical University of South Carolina researchers investigated the effects of mutations altering the structure of an essential protein in an antibiotic-resistant strain of Neisseria gonorrhoeae. They report in the Journal of Biological Chemistry that the mutations do not simply block antibiotics from binding to the protein but lock the protein in a shape that reduces its ability to interact with drugs. The findings pave the way for developing new antimicrobials to treat gonorrhea.
The microbes that inhabit our bodies are influenced by what we eat, drink, breathe and absorb through our skin, and most of us are chronically exposed to natural and human-made environmental contaminants. In a new paper, scientists from the University of Illinois at Urbana-Champaign review the research linking dozens of environmental chemicals to changes in the gut microbiome and associated health challenges.
Why is sex so popular in nature? A new article in Genome Biology and Evolution suggests that the molecular mechanisms underlying sex and the stress response may be more tightly coupled than previously appreciated, providing a new explanation for the widespread prevalence of sex in nature.
Brazilian researchers show that the virus can infect different placental regions and that collection and storage methods should be taken into consideration to ensure that the results are trustworthy and representative.
In the latest auto-commentary from SLAS Discovery, 'Controlling Phosphate Removal with Light: The Development of Optochemical Tools to Probe Protein Phosphatase Function,' researchers from the University of Pittsburgh Department of Chemistry (Pittsburgh, PA, USA) explain the design principles considered in developing an optically controlled protein phosphatase, opportunities and limitations of the methodology.
Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in recording, in action, a light-driven sodium pump from bacterial cells. The findings promise progress in the development of new methods in neurobiology. The researchers used the new X-ray free-electron laser SwissFEL for their investigations. They have published their findings today in the journal Nature.
Pneumococcus kills 1 million children annually according to the World Health Organization. The key to the pathogen's virulence is its thick sugar capsule, which is also the active ingredient in vaccines. Different strains have different capsules. Researchers just identified a new capsule for the pneumococcus -- the 100th to be found after more than a century of research on the pathogen.
What if doctors could not only diagnose a COVID-19 infection but identify which patients are at the greatest risk of death before any major complications arise? One Michigan State University scientist believes nanotechnology may be the answer.
Sometimes scientists begin research and find exactly what they expected. Other times they discover something unexpected. Such was the case for a group of scientists studying plant stress responses who stumbled upon a new mutation.
