  • In Battlestar Galactica (2004) robots called Cylons attack the humans by hacking their computer network. They are able to destroy most of humanity and all but a handful of human ships. One of the ships that survives is the Battlestar Galactica, an old ship that was about to become a museum, and is too old to be connected to the network. The man in the picture is Admiral William Adama, captain of the Galactica. He orders that computers are not to be networked together, so they can’t be hacked by the Cylons.

    In real life cyber security provider CrowdStrike had a bug in one of its update files. The file went out as part of an automated update to computers at many businesses around the world, including banks and airlines. The bug made the computers crash, grounding flights, making payment systems inoperable, etc.

    Amino acids are the basic building blocks of life. DNA encodes which animo acids to put together in which order, and when. Ribosomes read bits of RNA that was copied from DNA and match up amino acids. The different animo acids correspond to different three nucleotides combinations (the As, Cs, Gs, and Ts of DNA). The ribosome attaches each animo acid in a chain.

    When the amino acid chain detaches from the ribosome it folds into a protein. Different amino acids in different orders affect how the protein folds and what it becomes. Proteins are the structures and machinery of our cells.

    There are 20 amino acids we need to make the proteins we rely on. Our bodies can make some of them and some of them we can’t. The ones our bodies can’t make we have to get from our diet. Those ones are called vital amines, or vitamins for short.
