NewsResearch team traces evolutionary history of bacterial circadian clock on ancient Earth
To better understand the circadian clock in modern-day cyanobacteria, researchers studied ancient timekeeping systems. They examined the oscillation of the clock proteins in modern cyanobacteria, comparing it to the function of ancestral Kai proteins.

NewsCould nanoplastics in the environment turn E. coli into a bigger villain?
New research suggests certain nanoplastics may make foodborne pathogens more virulent. Nanoplastics with positively charged surfaces were more likely to cause physiological stress in E. coli O157:H7, making them pump out more Shiga-like toxin.

NewsWHO validates Mauritania for eliminating trachoma as a public health problem
The World Health Organization (WHO) has validated Mauritania as having eliminated trachoma as a public health problem, making it the seventh country in WHO’s African Region to achieve this significant milestone.

NewsPapua New Guinea eliminates trachoma as a public health problem
Papua New Guinea (PNG) has been validated by the World Health Organization (WHO) for eliminating trachoma as a public health problem. Trachoma, the world’s leading infectious cause of blindness, no longer poses a public health threat in the country.

NewsSeawater microbes are powerful tool for diagnosing coral reef health and strengthening conservation efforts
Microorganisms in the water surrounding coral reefs provide valuable insights on the health state of reefs and surrounding ocean. Sampling and analyzing reef water microbes can be done in a variety of ways ranging in cost and complexity, adding to their usability.

NewsNew molecular movie reveals how antibiotic resistance to fusidic acid works
Researchers revealed how FusB, a resistance protein found in clinically resistant strains of the bacterium Staphylococcus aureus, can rescue ribosomes from the antibiotic fusidic acid. FusB works like a molecular crowbar to free the blocked ribosome.

NewsAI predicts bacterial resistance to cleaning agents
With the help of artificial intelligence and DNA decoding, a new method can predict how well disease-causing bacteria such as Listeria tolerate disinfectants. This research may become a valuable weapon in the fight against harmful bacteria.

NewsResearchers find CRISPR is capable of even more than we thought
Researchers studying key immune components of some CRISPR systems have announced the newest CARF effector they’ve discovered, which they coined Cat1 - it can deplete a metabolite essential for cellular function.

NewsParticles carrying multiple vaccine doses could reduce the need for follow-up shots
Researchers are working to develop microparticles that can release their payload weeks or months after being injected. This could lead to vaccines that can be given just once, with several doses that would be released at different time points.

NewsScientists evaluate in-vitro activity of ceftazidime-avibactam against carbapenem-resistant gram-negative bacteria
Scientists explored the in-vitro activity of ceftazidime-avibactam (CAZ-AVI) in clinical isolates of carbapenem-resistant gram-negative bacteria collected at the outpatient, emergency, and inpatient departments of the Indus Hospital, Karachi.

NewsResearchers reveal lipid-based communication between body and gut microbes
A new study shows how a host protein can specifically recognize bacterial lipids, thus triggering beneficial immune responses. It also highlights a new way the body actively shapes the gut microbiome by communicating with microbes to maintain balance.

News New study reveals our skin’s own bacteria can help protect us from the bad effects of sunlight
Researchers have substantiated that certain skin bacteria can protect us from the sun’s ultraviolet (UV) radiation specifically by metabolizing cis-urocanic acid using an enzyme called urocanase. This enables the skin’s ability to fine-tune how it responds to UV radiation.

NewsScientists reveal key bacterial immune mechanism
Researchers have uncovered a pivotal mechanism by which bacteria defend themselves against viral infection. Cyclic dinucleotides (CDNs), synthesized during activation of the cyclic oligonucleotide-based anti-phage signaling system (CBASS) immune mechanism, trigger the filamentous assembly of phospholipase effectors, which execute the downstream immune response.

NewsTough microbes found in NASA cleanrooms hold clues to space survival and biotech
A new study involving AMI member Professor Alexandre Rosado has reported 26 novel bacterial species growing inside cleanrooms associated with NASA space missions. They carry genetic traits associated with resilience to extreme environments.
-
NewsScientists ID previously unknown enzymes that can produce potentially antimicrobial agents
Micro-organisms generate potential agents for combating bacteria and fungi. Researchers have identified and optimized enzymes that can specifically generate a certain functional group of these natural substances, expanding the toolkit of potential agents.

NewsActivating ‘jumping genes’ speeds up bacterial evolution from decades to weeks
Scientists have developed a system to control and accelerate the evolution of changes in the bacterial genome structure, targeting small ‘jumping genes’, or DNA sequences known as insertion sequences.

NewsHeart rhythm disorder traced to bacterium lurking in our gums
A new study finds that a gum disease bacterium can slip into the bloodstream and infiltrate the heart. There, it drives scar tissue buildup—known as fibrosis—distorting the heart’s architecture, interfering with electrical signals, and raising the risk of atrial fibrillation (AFib).

NewsBacterium yields secrets of how it produces ‘organic dishwashing liquid’ to degrade oil
The marine bacterium Alcanivorax borkumensis feeds on oil by producing an ’organic dishwashing liquid’ which it uses to attach itself to oil droplets. Researchers have now discovered the mechanism by which this “organic dishwashing liquid” is synthesized.
