My basic rule on all science is go at least look at the papers abstract, method and their graphs/data. In 5 minutes you'll be better informed than the pop science article and it gets easier the more you read them.
Interruption do impact getting back in but I find it very variable, I actually if I am doing very strict TDD I recover from interruptions well. If I am busy thinking about a design or doing some more complex algorithm performance analysis its all happening in my head and they take longer. I think it is measurable and you could set up experiments to see how long it took to start producing again and if there is a slow start or not on a well defined programming task.
