From BBC Two, Secret Universe: The Hidden Life of the Cell
Check out this spectacular cellular visualization featured on BBC Two last night. The hour-long documentary offers an accessible description of the internal conflict that occurs regularly in our bodies between viral pathogens and our immune defense mechanisms.
Although the program is given an evolutionary spin (it features Steve Jones and Nick Lane), the design and engineering implications of what is being shown are clear. It is well worth the time-investment. For those who don't have time to watch the full program, a three-minute preview clip can be found here.
