    From within the dark confines of the skull, the brain builds its own version of reality. By weaving together expectations and information gleaned from the senses, the brain creates a story about the outside world. For most of us, the brain is a skilled storyteller, but to spin a sensible yarn, it has to fill in some details itself.

    Last year, Joan Peay slipped on her garage steps and smashed her knee on the welcome mat. Peay, 77, is no stranger to pain. The Tennessee retiree has had 17 surgeries in the last 35 years — knee replacements, hip replacements, back surgery. She even survived a 2012 fungal meningitis outbreak that sickened her and hundreds of others, and killed 64. This knee injury, though, “hurt like the dickens.”

    A sugar that freshens air in rooms may also clean cholesterol out of hardened arteries. The sugar 2-hydroxypropyl-beta-cyclodextrin, or cyclodextrin, removed cholesterol that had built up in the arteries of mice fed a high-fat diet, researchers report. The sugar enhances a natural cholesterol-removal process and persuades immune cells to soothe inflammation instead of provoking it, say immunologist Eicke Latz and colleagues.

    Ketamine, a drug that has shown promise in quickly easing depression in people, doesn’t actually do the job itself. Instead, depression relief comes from one of the drug’s breakdown products, a study in mice suggests. The results identify a potential depression-fighting drug that works quickly but without ketamine’s serious side effects or potential for abuse.
