Microbiology
Staphylococcus aureus is a pathogenic bacteria well known for developing resistance to antibiotics, with dire consequences for human staph infections. This study explored the time required f…
Microbiology (inferred)
Antibiotic-resistant bacteria such as Methicillin-resistant Staphylococcus aureus (MRSA) and Salmonella Typhi can cause life-threatening illnesses in humans. The antimicrobial properties of…

Honorable_mention Award
The rising global health concern of bacteria becoming “resistant” to antibiotics is necessitating the discovery of new compounds to restore the effectiveness of existing antibiotics. This pr…
Microbiology
Biofilm formation is a major driver of antimicrobial resistance and persistent infections, particularly in medical device-associated settings. These structures protect bacteria from antibiot…
Microbiology
Antibiotic resistance is a rising global health threat, causing over 5 million deaths worldwide annually. This is a particular concern in hospital settings where bacterial infections can spr…
Microbiology
Dinoflagellates are one of the many marine organisms that perform bioluminescent processes. There are many factors that could affect the light that they produce, including temperature, salin…
Microbiology
Menstrual products are composed of harmful microplastics. Tampons specifically contain microplastics such as polyethylene (PE) which have been seen to interfere with biological functions. Ba…

Melatonin is a naturally occurring molecule found in many organisms that helps protect cells from damage caused by harmful molecules known as reactive oxygen species (ROS). Although its prot…
Microbiology
Previous studies have provided insights using quantitative measurements and controlled animal models, primarily focusing on persistent chemicals such as PFAS rather than the broader spectrum…
Microbiology
Polylactic acid (PLA) is a biodegradable bioplastic used in packaging, textiles, 3D printing, medical devices, and agricultural applications. Although derived from renewable resources, it de…
Microbiology
Per- and polyfluoroalkyl substances (PFAS) are a class of persistent environmental contaminants known to disrupt biological systems across multiple trophic levels, yet their cellular and mol…

I tested what type of homemade remedy is most effective in helping reduce bacteria: lemon, eucalyptus, or aloe Vera
Microbiology
The purpose of this study was to examine whether the production of genotoxic colibactin by the probiotic Escherichia coli strain Nissle 1917 (EcN) is influenced by external factors, such as…
