In new research released this month, a Florida State University team revealed that these mats are more complex than scientists […]

A scientist places a water sample onto a custom-made platform before a test. Each water sample contains microorganisms such as the parasite Giardia and adenoviruses, both of which can make humans sick. Credit: T. Larason/NIST NIST researchers describe unique system for testing how well narrow wavebands of UV light kill […]

Credit: © The British Library Board (Royal 12 D xvii) To fight antibiotic resistance more antimicrobials are needed to treat bacterial biofilms, which protect an infection from antibiotics. Using the ‘Balds eyesalve’ medieval mixture containing every day natural ingredients such as garlic, researchers from the University of Warwick have found […]

Sea star wasting disease, pictured here, is likely caused by the sea star associated densovirus.

As the global temperatures continue to climb, it also raises uncertainties as to the relationship, prevalence, and spread of […]

These pathogens use a small protein with a large impact: The RNA-binding protein ProQ is involved in the activation of […]

A watercolor-like illustration of Treponema pallidum, the bacterium that causes syphilis. Credit: Alice C. Gray By shuffling DNA in and out of one gene, syphilis stays a step ahead of the immune system to resist eradication. The bacterium that causes syphilis, Treponema pallidum, likely uses a single gene to escape the immune system, […]

When Sierra Simpson was in college, she was sick for a year with recurring fevers and vomiting. Her doctors couldn’t figure out what she had. Suspecting a bacterial infection, they tried treating her with high doses of antibiotics. “It turned out I had malaria and needed a different treatment,” Simpson […]

Purified schizorhodopsin protein in water solution. Credit: © 2020 Inoue et al. Unique protein acts as an inward proton pump in a distant microbial relative. Researchers investigated the group of microorganisms classified as Asgard archaea, and found a protein in their membrane which acts as a miniature light-activated pump. The schizorhodopsin […]
