This is Scientific Americans' 60-second science. I'm Steve Merski. Got a minute?

After Connecticut passed a law requiring background checks and gun safety courses, gun deaths decreased by 40%.

President Obama today, in his announcement that he was taking executive action to require more gun sellers to be licensed

and to do background checks on gun buyers, he also touched upon the problems facing public health

researchers who try to study gun violence and deaths.

Meanwhile, since Missouri repealed a law requiring comprehensive background checks and purchase

permits, gun deaths have

increased to an almost 50 percent higher than the national average. One study found,

unsurprisingly, that criminals in Missouri now have easier access to guns. And the evidence tells us that in states that require background checks,

while abiding Americans don't find it any harder to purchase guns whatsoever. Their guns

have not been confiscated, their rights have not been infringed. And that's just the information

we have access to.

With more research, we could further improve gun safety.

Just as with more research, we've reduced traffic fatalities enormously over the last 30 years.

We do research when cars, food, medicine, even toys, harm people so that we make them safer.

And you know what?

Research, science, those are good things.
