New tool combines 360° video with spatial audio recording to accurately identify fish through sound.

Recordings are the most extensive bank of natural fish sounds published to date, including many sounds that have never been identified.

These sounds can be used to interpret soundscapes to monitor the health of threatened coral reefs to a new level of detail.

Additive manufacturing, also known as 3D printing, has proven transformative for fabricating electrically conductive polymer nanocomposites that incorporate carbon nanotubes. However, existing methods struggle to achieve high stretchability while maintaining electrical conductivity, limiting practical applicability. Now, researchers from Korea have developed highly stretchable carbon nanotube-nanocomposites, optimized specifically for vat photopolymerization type 3D printing. Using these materials, they also developed a wearable smart-insole sensing platform for real-time foot pressure monitoring.

A research paper just published in Science China Life Sciences reports that Christensenella tenuis alleviates endotoxemia and metabolic disorders in obese mice via inhibition of intestinal lipopolysaccharide (LPS) translocation. The study uncovers a novel probiotic mechanism and suggests therapeutic potential for metabolic diseases.

The yeast fungus Candida albicans not only uses the toxin candidalysin to cause infections, but also to colonize the oral mucosa inconspicuously – but only in finely balanced amounts. Too little toxin prevents oral colonization, too much triggers the immune system and leads to an inflammatory defense reaction, as an international research team from Zurich, Jena, and Paris discovered. The results were published in the journal Nature Microbiology.
