    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.

    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.

    A few months back, two puffy, red eyes full of goop landed my toddler in the doctor’s office, where an exam also turned up two ear infections. This double-eye, double-ear whammy led to her first dose of antibiotics, post haste.

    A long course of antibiotics reduced the levels of a hallmark of Alzheimer’s disease in the brains of mice, possibly by changing the species of bacteria in the gut. The results suggest that gut bacteria may be linked in some way to Alzheimer’s.

    A notorious Alzheimer’s disease villain may also be a germ-busting superhero. Amyloid-beta gums up the brains of people with Alzheimer’s but also takes out brain invaders, scientists report. As strong as steel, tough strands of A-beta protein imprison pathogens that threaten the body and brain, experiments in mice and worms show. Those results raise the possibility that A-beta plays a role in the immune system and its accumulation in Alzheimer’s might be prompted by infection.

    For some people, fentanyl can be a life-saver, easing profound pain. But outside of a doctor’s office, the powerful opioid drug is also a covert killer. In the last several years, clandestine drugmakers have begun experimenting with this ingredient, baking it into drugs sold on the streets, most notably heroin. Fentanyl and closely related compounds have invaded the entire heroin supply.
