Can We Get Older Without Aging?
Nothing is guaranteed in life except death, taxes, and entropy. What do other life forms have to teach us about staying alive as we get old, and will we ever conquer death?

TED-Ed: Why do our bodies age? - Monica Menesini
Human bodies aren't built for extreme aging: our capacity is set at about 90 years. But what does aging really mean, and how does it counteract the body's efforts to stay alive? Monica Menesini details the nine physiological traits that...

TED-ED: How to sequence the human genome - Mark J. Kiel
Your genome, every human's genome, consists of a unique DNA sequence of A's, T's, C's and G's that tell your cells how to operate. Thanks to technological advances, scientists are now able to know the sequence of letters that makes up an...

5 Things We Still Get Wrong About Human Reproduction
You'd think we'd know everything there is to know about sexual reproduction. But as it turns out, there are still quite a few things we picked up that aren't exactly true, and we're here to correct that. Chapters NEW EGGS 1:47 MENSTRUAL...

Mendel Got Extremely Lucky (...or Maybe He Lied)
Science, while often the result of a stroke of genius, can just as easily be a stroke of extraordinarily good luck. Mendel’s work just happened to be a mix of the two.

Operon
In this video Paul Andersen describes the elements of an operon. The promoter allows the RNA polymerase to transcribe the required genes. The operator and repressor regulate the expression of the genes by blocking the RNA polymerase. The...
