Some of the oxygen on the moon used to be on planet Earth

Scientists say that every month, we here on Earth send some oxygen to the moon — and we’ve probably been doing it for billions of years.

The moon may be airless, but we know it has oxygen — Apollo mission samples confirmed its presence in the moon’s soil. The easiest explanation for its source is the solar wind, which bombards the moon’s surface with particles streaming off of the sun. But new research shows that the moon may be getting some of its oxygen from a more familiar place: Earth.

There's 'alien soil' growing deep underground

Almost one-third of a mile underground, in the dark, damp vaults of the vast Frasassi cave system in central Italy, curious patterns appear on the walls. Stretching for miles, the designs are slimy to the touch, similar to the consistency of wet clay.

For years, fighting the spread of child pornography online was like playing a dark game of whack-a-mole: Scrub an image of abuse from one location, and it would just rear its head again later, in another corner of the web.

That is, until 2008, when Dartmouth College computer scientist Hany Farid teamed up with Microsoft. Together, they built a tool that could compare an image’s digital signature, or “hash,” against a database of known child pornography, cataloged by the National Center for Missing and Exploited Children.

In the run-up to last fall’s US presidential election, fake news swept social media sites like a virus, unleashing alternative facts that many people thought were real. One reason we may have been so susceptible to false facts? A consensus is powerful, experts say — especially when our brains are handling a lot of information quickly.
