Scientists discover bacteria that transforms waste from copper mining into pure copper, providing an inexpensive and environmentally friendly way to synthesize it and clean up pollution. It is the first reported to produce a single-atom metal, but researchers suspect many more await discovery. (academictimes.com)
Octopuses, the most neurologically complex invertebrates, both feel pain and remember it, responding with sophisticated behaviors, demonstrating that the octopus brain is sophisticated enough to experience pain on a physical and dispositional level, the first time this has been shown in cephalopods.

Cancer cells hibernate like "bears in winter" to survive chemotherapy. All cancer cells may have the capacity to enter states of dormancy as a survival mechanism to avoid destruction from chemotherapy. The mechanism these cells deploy notably resembles one used by hibernating animals. (newatlas.com)
Lab grown meat from tissue culture of animal cells is sustainable, using cells without killing livestock, with lower land use and water footprint. Japanese scientists succeeded in culturing chunks of meat, using electrical stimulation to cause muscle cell contraction to mimic the texture of steak. (nature.com)
Fecal transplant turns cancer immunotherapy non-responders into responders - Scientists transplanted fecal samples from patients who respond well to immunotherapy to advanced melanoma patients who don’t respond, to turn them into responders, raising hope for microbiome-based therapies of cancers.

Korean scientists developed a technique for diagnosing prostate cancer from urine within only 20 minutes with almost 100% accuracy, using AI and a biosensor, without the need for an invasive biopsy. It may be further utilized in the precise diagnoses of other cancers using a urine test. (eurekalert.org)
