A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.

Researchers have invented a nano-thin superbug-slaying material that could one day be integrated into wound dressings and implants to prevent or heal bacterial infections. The innovation -- which has undergone advanced pre-clinical trials -- is effective against a broad range of drug-resistant bacterial cells, including 'golden staph', which are commonly referred to as superbugs.

Researchers have developed a measurement technique that rapidly measures the number of viable bacteria in food products. They have succeeded in drastically reducing the inspection time from 2 days to about 1 hour. With this technology, it will be possible to confirm food safety before shipment from factories and prevent food poisoning.

Researchers have unveiled an intriguing phenomenon of cellular reprogramming in mature adult organs, shedding light on a novel mechanism of adaptive growth. The study, which was conducted on fruit flies (Drosophila), provides further insights into dedifferentiation -- where specialized cells that have specific functions transform into less specialized, undifferentiated cells like stem cells.
