Somalia hadn't had a case of polio for nearly six years. But in the past few months, the virus has come back. Now the East African country has the worst polio outbreak anywhere in the world.
Twenty new cases of polio were reported this week in Somalia by the Global Polio Eradication Initiative. That brings the total number of cases in the Horn of Africa to 73. The rest of the world combined has tallied only 59 cases so far this year.
Scientists have spent the last five years serving up rodent-sized alcoholic drinks to hundreds of little black and white rats, after a nice hit of nicotine.
These miniature cocktail parties have provided a clearer view on why nicotine and alcohol are so often used, and abused, together.
"It's pretty well understood by most people that those who smoke are more likely to drink," John Dani, a professor of neuroscience at the Baylor College of Medicine, told Shots. "And these people are ten times more likely to abuse alcohol."
