But a new study shows giving buses an inexpensive engine retrofit helps not only the health of students who ride them, but also their academic performance. The study looked at a variety of school districts over time and concluded that test gains from green buses were like going from a rookie teacher to one with more than five years of experience.

Medical Notes 19-50


Medical notes this week…

Alcoholic liver disease kills more than 20,000 people per year in the United States, but scientists may someday be able to treat it with something short of a liver transplant. A study in the journal Nature finds that when mice with alcoholic liver disease are treated with a bacteria-killing virus, their liver disease is wiped out. The virus targets a specific gut bacteria which produces liver-attacking toxins. Those bacteria are very numerous in people with alcoholic liver disease. Scientists say it’ll be some time before they can try the virus on people.

If you want to keep the mind alive as you age, play games. A study in the Journals of Gerontology followed people from age 70 to 79 and found that those who played games like bingo, cards, crosswords and chess had less of a decline in thinking compared to people who didn’t play games. The effect was most profound in memory and thinking speed. Scientists are hoping to refine their study further to narrow down which games are best for the brain.

And finally, school buses are among the oldest and most polluting vehicles on the road. But a new study shows giving buses an inexpensive engine retrofit helps not only the health of students who ride them, but also their academic performance. The study looked at a variety of school districts over time and concluded that test gains from green buses were like going from a rookie teacher to one with more than five years of experience.
