What's the difference between "scientific journal" and "magazine on science"?
What's the difference between "scientific journal" and "magazine on science"? Please read the passage first.
Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday.
They found that when people listened to their favorite music, their blood vessels dilated in much the same way as when they are laughing, or taking blood medications.
"We have a pretty impressive effect," said Dr Michael Miller, director of preventive cardiology at the University of Maryland Medical Center in .
"Blood vessel diameter improved," he said. "The vessel opened up pretty significantly. You can see the vessels opening up with other activities such as exercise." A similar effect is seen with drugs such as statins.
When blood vessels open up more, blood flows more smoothly and is less likely to form the clots that cause heart attacks and strokes. "We are not saying to stop your statins or not to exercise but rather to add this to an overall program of heart health," said Miller, who presented his findings to a meeting of the American Heart Association in .
Miller's team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music. They spent half an hour listening to the recordings and half an hour listening to music they said made them feel anxious while the researchers did ultrasound tests designed to show blood vessel function.
Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average when the volunteers heard their joyful music. Listening to music they disliked — in most cases in this group heavy metal — blood vessels narrowed by six percent, Miller said.
Miller said he came up with the idea after discovering that laughter caused blood to literally flow more smoothly. "I asked myself what other things make us feel real good, besides calories from dark chocolate of course. Music came to mind. ... It makes me feel really good," he said.
Most of the volunteers chose country music but Miller said the style is not so important rather than what pleases each individual.

Both passages contain grammatical errors which suggest to me a newspaper or magazine source. However, some Scientific journals lack strict accuracy so I can't be certain.

I would suggest that a "magazine on science" is aimed at the general public and covers topics of interest in the fields of science to people who are not scientists. Someone interested in astronomy might subscribe to a magazine on that subject, making it a "magazing on science." There is even a magazine called "Popular Science."
A scientific journal is read by scientists in that field. It
