The laboratory investigation revealed that honey from the native bee Tetragonula carbonaria halted the growth of resilient hospital pathogens like Pseudomonas aeruginosa alongside fungi causing athlete's foot and ringworm. Propolis from the same species showed a remarkably selective profile, leaving certain microbes unaffected while neutralizing specific targets. Long incorporated into Indigenous medicine, these native bee products possess mechanisms distinct from traditional European honey bee varieties. Future research led by study supervisor Dr. Kenya Fernandes will center on identifying the precise compounds driving these antibacterial effects.

For generations, Australia’s tiny native stingless honey bees have been part of Indigenous medicine. Scientists now believe they may hold clues to tackling one of modern medicine’s biggest challenges: antibiotic-resistant bacteria. Researchers at the University of Sydney examined the potential medicinal benefits of honey and propolis (a mixture of plant resin and beeswax that bees use to build their nests) produced by Australia’s stingless bees, and the early results are hard to ignore. They found that the honey stopped the growth of every bacterium tested, including two hard-to-treat pathogens. These sugarbag bees hold valuable clues to tackling the growing threat of antimicrobial resistance. The findings are published in the journal
PLOS One.
Australia’s stingless bees could combat antibiotic resistance
Stingless bees, also known as sugarbag bees, are native to Australia. Their honey has long been used in Indigenous medicine. However, almost all research on medicinal honey has focused on the European honey bee. These Australian species have been largely left out of the conversation. A new study led by PhD candidate Jasmin Li aimed to close that gap. Li’s team…
Developmental cognitive limits often prevent young children from executing daily parental requests even when they fully comprehend the instructions. Psychologists note that competing distractions derail an immature prospective memory system, making it difficult to shift attention toward scheduled tasks. Recognizing these constraints helps families implement practical environmental supports rather than relying solely on repetitive verbal commands.
University of Oxford researchers found that Manx shearwaters navigating by the sun experience circadian mismatches equivalent to human jet lag during rapid east-west journeys. These temporal errors directly alter flight headings, pulling the birds off course during open-ocean migrations. Understanding how these animals handle repeated circadian disruptions could eventually yield new insights into human travel resilience.
Microscopic and chemical analyses of artefacts from the Sanxingdui sacrificial pits reveal that the ancient Shu civilization regularly incorporated woven textiles into their Late Shang period religious ceremonies. Archaeologists found that these communities adorned and wrapped sacred bronze, gold, jade, and ivory items with fine mulberry fabric. This evidence demonstrates that complex textile production was an established ritual practice in Sichuan Province more than three millennia ago.
