President Obama's Farewell Address to the American People

Over his nearly hour-long speech, President Obama cited the challenges, successes, failures, and his still-strong belief in the ability of this nation to change for the better.

  • 3D Graphene

    Graphene is thought to be the strongest material known — in its two-dimensional form. Replicating that 2D strength in three dimensions has been problematic for scientists for decades. But researchers at MIT think they've found a solution. This new 3D-printed material has just 5% of the density of steel with over 10 times the strength, opening doors for applications from airplanes to filtration systems.
