Since the original series went on the air in 1966, the Star Trek franchise has had a history of ups and downs in the toy business - from AMT's faithful scale model kit of the USS Enterprise to Remco's obscure tie-in merchandise, to Mego's best–selling action figure line. Following Mego's bankruptcy in 1983 and a string of flops by Ertl and Galoob, Playmates Toys picked up the toy license in the late 1980s and sparked a resurgence in the franchise's toy sales.
From the mid-2000s onwards, companies such as Art Asylum and McFarlane Toys continue to keep the Star Trek toy franchise alive.

The nervous system is fundamentally electric. When we move our arm, it moves because a electric signal has been sent to the muscle that controls it. Now, because the brain is electric, we could also use electricity to record what the brain is doing or bypass it entirely, and control a body. That means that we could restore movement to people who are paralyzed, feel through an artificial hand as if it was our own, and even read people's minds.
Michael Stevens explores how electricity can be used to move cockroaches, control other peoples' limbs and even read peoples' thoughts.

In 1949, after decades of making wooden furniture and toys, Ole Kirk Christiansen's small factory in Billund, Denmark, moved to plastic and created the 'Automatic Binding Bricks', which would later be known as LEGO. When the company patented the tube system in 1958, LEGO became the dominant toy line worldwide throughout the 1960s and 1970s. When other competitors capitalized on the expiration of the company's patents in the 1980s, LEGO faced stiff competition until they reported their first loss in 1998. Poor business decisions with film licenses and the failure of the Jack Stone and Galidor lines brought LEGO to near-bankruptcy until Jørgen Vig Knudstorp took over the company and, by bringing it back to its roots, rejuvenated LEGO's profits.
By the time The Lego Movie hit theaters in 2014, LEGO became the largest toy franchise in the world.

What's behind a pulse? The second episode dives into the world of an ice climber, a bus driver, a woman in labor, and a senior dance club to show how the human heart and the circulatory system power our physical and emotional lives, and create the pulsing rhythm of our world.

Someday, I will die. But should I? If I was offered a longer life, I would take that in a second. But how long is too long? Is death something I should deny forever, or is death and the role it plays in the universe something I am better off accepting?
