Seeking to learn more about the biology of addiction, researchers at the University of Utah have built a system that allows zebrafish to give themselves small doses of hydrocodone, an opioid synthesized from codeine.
After a week, according to STAT, the fish started taking risks if it meant they could get another dose and when the hydrocodone was taken away, they became anxious and stressed, apparent signs of withdrawal.
Zebrafish are a longtime, helpful model for investigating human biology. By showing similar behaviors, researchers hope to better understand the basic mechanisms of addiction afflicting people.

Two of the downsides of an aging population: You go to the doctor more often and there's a greater chance you won't hear what he or she tells you.

The study didn't look at whether any of the miscommunications resulted in medical errors but noted that the prevalence of errors generally rises with patients' age.

A woman walked up to a little, wrinkled, sallow man sitting in a chair on his porch.
"I couldn't help noticing how happy you look," she said. "What's your secret for a long happy life?"
"I smoke three packs of cigarettes a day," the man replied. "I also drink a case of whiskey a week, eat fatty foods and never exercise."
"That's amazing," the woman said. "How old are you?"
"If people let the government decide what foods they eat and what medicines they take, their bodies will soon be in as a sorry state as the souls who live under tyranny."
