After a seven-month journey, NASA’s Perseverance Rover successfully touched down on Mars on February 18, 2021. In this video, mission controllers at NASA's Jet Propulsion Laboratory in California celebrate landing NASA's fifth rover on Mars.

We’ve all seen footage of the first men walking on the moon... but how exactly did they get there? This video details the fascinating, many-faceted construction of the Apollo 11 spacecraft so that we can see exactly what happened in what order to make this incredible journey a reality.

Actress, author, and neuroscientist Mayim Bialik considers open relationships. While she sees the benefits, there are certainly things she doesn’t “get” about this kind of arrangement, as she sees male and female biology clearly dictating different ideals.

Mayim shares her doubts and misgivings about open relationships. It seems that for her, the commitment, predictability, and closeness of a monogamous relationship is all together more meaningful and enjoyable.

In a TEDx Talk, brain researcher Dr. Lara Boyd talks about neuroplasticity, how we learn, and how short-term and long-term memory work.

Lara Boyd talks further about behavior bringing about changes to the brain, and about why it's so hard to recover after a stroke.

Lara Boyd concludes her fascinating talk on the brain, explaining how personalized medicine and biomarkers can apply, not just to recovery from stroke and cancer treatment, but to teaching and learning in everyday life.
