Researchers at Stanford and NASA have developed a new robotic gripper that resembles gecko feet for use in space.

How it works: Geckos have small hairs on their feet that collectively work as an adhesive and allow them to climb smooth, vertical surfaces. The robotic gripper mimics those hairs using thousands of silicone rubber wedges pointing in opposite directions. When pulled together, they produce an adhesive force.

Why it matters: Hundreds of thousands of pieces of space junk orbit Earth, increasing the likelihood of space collisions and, in some cases, occupying prime positions for new satellites. If the gecko-inspired gripper can work in the cold environment of space (something the researchers plan to test), it could help robots collect debris and help clear the way.

The debut of "Hamilton" on Disney+ last Friday sent downloads of the app soaring over the weekend.

Why it matters: With theaters closed until 2021, "Hamilton" is the biggest litmus test for whether Broadway will ever be able to successfully transition some of its iconic hits.

Wall Street is no longer betting on Trump

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.
