NewsSuper-resolution imaging reveals details inside living cells
A new fluorescence microscopy technique that generates super-resolution images from a single camera exposure could help researchers study rapid movements within cells that are difficult to capture with existing methods.

NewsHow cholera bacteria swap defenses against viruses
To survive viral attack, bacteria equip themselves with antiviral immune systems. Vibrio cholerae carries a large genetic element called a sedentary chromosomal integron (SCI). A new study investigates whether the SCI might capture gene cassettes from genetic material entering the cell from the outside.

NewsUltra-selective aptamers give viruses a taste of their own medicine
Inspired by the way viruses attach to cells, scientists have developed a method for engineering ultra-selective aptamers. The synthetic molecules bind to targets like viral spike proteins, making them useful for biomedical diagnostics and treatments.

NewsScientists uncover how certain cholera strains are so successful at evading phage attacks
A new study shows that a virulent lineage of cholera acquired multiple distinct bacterial immune systems that have protected it from diverse types of phages. This defense may have contributed to the massive scale of the Latin American epidemic.

NewsA lung pathogen’s dilemma: infect or resist antibiotics?
Research has uncovered how Pseudomonas aeruginosa manages the trade-off between colonizing and surviving during infection by switching between biofilm formation for antibiotic protection and a more mobile, “planktonic” state to spread and access nutrients.

NewsE coli bacteria engineered to generate electricity from wastewater
Scientists have reported a groundbreaking achievement in bioelectronics, advancing the capabilities of common E. coli bacteria to generate electricity.
