3 weeks agoCapturing dynamic phage-pathogen coevolution by clinical surveillance - Nature
Phage-inducible chromosomal island-like elements (PLEs) in Vibrio cholerae provide defense against ICP1 phage predation, influencing pandemic strain evolution and disease severity through dynamic phage-bacteria interactions.

Treponemal diseases, including syphilis, originated much earlier than thought; a 5,500-year-old Treponema pallidum genome from Colombia pushes back their evolutionary timeline.

DNA variants near a gene called MSRB3 - which is important for hearing in humans - could determine whether a dog's ears are pendulous like a basset hound's or stubby like a rottweiler's. Researchers analysed the genomes of thousands of canines and found that small, single-letter changes to DNA in a region of the genome near MSRB3 could boost the gene's activity. The boost can increase the rate at which ear cells proliferate, resulting in longer ears.

1 month agoA bacterium frozen 5,000 years ago has been found capable of standing up to super-pathogens
A 5,000-year-old Psychrobacter strain recovered from Romanian cave ice displays resistance to multiple modern antibiotics and produces compounds that inhibit other, hard-to-treat pathogens.

2 months agoMeet the extremophile molds wreaking havoc in museums
Mold is a perennial scourge in museums that can disfigure and destroy art and artifacts. To keep this microbial foe in check, institutions follow protocols designed to deter the familiar fungi that thrive in humid settings. But it seems a new front has opened in this long-standing battle. I'd recently heard rumblings that curators in my then home base of Denmark have been wrestling with perplexing infestations that seem to defy the normal rules of engagement.
