U.S. Customs and Border Patrol officially opened its request for proposals to design and build President Trump's border wall on Friday, per WSJ.

Here's what they want it to look like:

  • About 30 feet high (minimum is 18 feet) and made of concrete or "alternative material"
  • Stretching all the way from San Diego to Brownsville
  • Including anti-climbing fixtures, and sturdy enough to withstand chisels and torches
  • Running at least 6 feet below ground to prevent tunneling
  • A "see-through" component would be ideal, and it should incorporate "sliding gates" to allow cars and pedestrians to pass through.
  • The U.S.-facing side of the wall should be "aesthetically pleasing", so it is consistent with the surrounding environment.

As of this week, more than 600 companies have begun to bid for the opportunity to build Trump's wall. The federal budget, released Thursday, calls for $1.5 billion to be allocated to the wall in FY17, and $2.6 billion in FY18.

Federal coronavirus aid for airlines expires on Thursday with no renewal in sight, meaning massive layoffs for the industry aren't far behind.

The big picture: Airline workers aren't alone on the unemployment line. Oil companies, tire manufacturers, book publishers and insurers are among those that have announced tens of thousands of layoffs. Federal aid through the CARES Act earlier this year delayed most layoffs — until now.

Uncertainty can be hard for humans. It drives anxiety, an emotion neuroscientists are trying to understand and psychologists are trying to better treat.
