Plain English
Researchers blocked a protein called calpain in mouse pancreas cells and found that doing so for 48 hours reduced insulin secretion by 40-80%, apparently by damaging the cells' ability to process glucose for energy. This discovery matters because a genetic variation in the calpain gene is linked to type 2 diabetes risk, and this experiment shows a potential mechanism: if calpain doesn't work properly, the insulin-producing cells fail to do their job.

Plain English
This study looked at how different opioids, like morphine and methadone, impact brain cells in rats, particularly in the hippocampus, which is important for learning and memory. Researchers found that using these opioids reduces certain signals between brain cells, with chronic use leading to decreased responsiveness to the same or different opioids after treatment.
