Scientists have invented a skin patch that generates power from sweat, according to New Scientist. Sweat powered a radio for two days and could eventually be used for devices to monitor medical conditions.

How it works: The patch contains enzymes that replace batteries and "feed off sweat to provide power." Joseph Wang, a member of the team from U.C. San Diego that worked on the technology, told New Scientist: "If you were out for a run, you would be able to power a mobile device."

What's next: Right now there is extensive research into flexible sensors and electronics that would allow people to continually monitor health conditions through wearable devices. Wang hopes these sensors could eventually generate "enough power for a Bluetooth connection" so results could be read off a smartphone.

How Biden might tackle the Iran deal

Four more years of President Trump would almost certainly kill the Iran nuclear deal — but the election of Joe Biden wouldn’t necessarily save it.

The big picture: Rescuing the 2015 Joint Comprehensive Plan of Action (JCPOA) is near the top of Biden's foreign policy priority list. He says he'd re-enter the deal once Iran returns to compliance, and use it as the basis on which to negotiate a broader and longer-lasting deal with Iran.

Kamala Harris, the new left's insider

Progressive leaders see Sen. Kamala Harris, if she's elected vice president, as their conduit to a post-Biden Democratic Party where the power will be in younger, more diverse and more liberal hands.

  • Why it matters: The party's rising left sees Harris as the best hope for penetrating Joe Biden's older, largely white inner circle.

If Biden wins, Harris will become the first woman, first Black American and first Indian American to serve as a U.S. vice president — and would instantly be seen as the first in line for the presidency should Biden decide against seeking a second term.
