NewsNo more antibiotics? Scientists pioneer a safer way to protect cultured meat
A new study explores the use of Random Antimicrobial Peptide Mixtures (RPMs) as a safe and effective alternative to antibiotics in cultured meat production. These synthetic peptide cocktails eliminate bacterial contamination without harming stem cell viability or contributing to antibiotic resistance.

NewsResearchers uncover how Staphylococcus aureus ‘steals’ iron from our blood during infections
Researchers have revealed how Staphylococcus aureus bacteria extract iron from hemoglobin – a process crucial to their survival during infections. The study has identified the full sequence of protein–protein interactions during this iron ‘theft’.

NewsScientists develop new natural killer cell strategy to target HIV
Scientists have successfully identified a new approach using natural killer (NK) cells to target and kill the HIV-positive cells that allow the virus to persist. They genetically modified NK cells to express CD64, a protein not normally expressed by NK cells.

NewsMonitoring approach could help snuff out Legionella outbreaks
Routine, relatively low-cost monitoring of several factors influencing water safety could ward off Legionnaires’ disease outbreaks in hospitals, nursing homes and other health care settings, a new study suggests.

NewsProfessor awarded NSF grant to advance research on silica-scaled chrysophytes
A new National Science Foundation (NSF) grant will support a major effort to synthesize decades of research on protists. The project will integrate findings from Professor Peter Siver’s lifelong study of silica-scaled chrysophytes, a group of protists found in freshwater environments.

NewsEliminating HIV funding program would lead to >600k deaths in South Africa alone: warning
A new analysis finds that eliminating PEPFAR would lead to 601,000 HIV-related deaths, 565,000 new HIV infections, and would increase population-level healthcare expenditure by $1.7 billion over the next decade in South Africa alone.

NewsScientists to forecast climate tipping points by capturing ocean’s pulse - plankton
A new project is set to revolutionise climate forecasting by focusing on plankton as the “canaries in the coalmine” of ocean health. Next-generation autonomous underwater robots will deliver near real-time observations in the North Atlantic subpolar gyre.

NewsVentilation fans can significantly lower the risk of inhaling bacteria particles after toilet flushing
New research finds that unhealthy concentrations of bacteria are released into the air by toilet flushing - but active ventilation with an exhaust fan reduce the risk by 10 times.
