Scientists at Brown University have found evidence that the moon could contain more water than previously thought.

How they found it: Using images of the moon's surface, researchers measured the amount of water trapped in volcanic deposits across the surface of the moon by looking at sunlight reflected from the rocks.

"It's not much [water], maybe a couple hundreds parts per million, but the size of these deposits are huge, you have a lot of material to work with," Ralph Milliken, the lead author of the study, told Popular Science. "Theoretically, we could extract water from these deposits for human exploration."

Why it matters: If — and that is a big if right now — water on the moon could be extracted, it could be used as a pitstop on the way to Mars. Elon Musk suggested something similar recently in calling for a base for the moon.

Betting markets have turned decisively toward an expected victory for Joe Biden in November — and asset managers at major investment banks are preparing for not only a Biden win, but potentially a Democratic sweep of the Senate and House too.

Why it matters: Wall Street had its chips on a Trump win until recently — even in the midst of the coronavirus-induced recession and Biden's rise in the polls.

With new security law, China outlaws global activism

The draconian security law that Beijing forced upon Hong Kong last week contains an article making it illegal for anyone in the world to promote democratic reform for Hong Kong.

Why it matters: China has long sought to crush organized dissent abroad through quiet threats and coercion. Now it has codified that practice into law — potentially forcing people and companies around the world to choose between speaking freely and ever stepping foot in Hong Kong again.
