10 common scientific misconceptions

Did you grow up believing in any of these science myths? From baby birds to flushing toilets, we debunk common 'facts' that are often just a form of misconstrued science. 

8. All bat species are blind

Spectacle fruit bats, aka flying foxes, the largest bat in Australia, hang upside down in the trees during the day to rest and feed by night.

All bat species can actually see, although at varying levels. Not all bats even use echolocation to find food – fruit bats typically use their nose to locate fruit.
Another common belief is that they can see only at night.

In fact, scientists at the Max Planck Institute found that the retinas of fruit bats also contain cone photoreceptor cells, which detect color and are located mainly in the center of the retina. The cones are not very sensitive to light, so they are typically used for day (or "photopic") vision. 

The 2007 study disproved earlier claims that bat eyes contained only rod cells, which are located mainly on the edge of the retina and are responsible for night and peripheral vision. Cone cells also have a higher level of visual acuity than rods – that is, they are more helpful in the sharpness of vision than rods.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
