bacteria

A two-minute time-lapse from the Kishony Lab showing bacteria spreading across a giant petri dish with increasing antibiotic doses, evolving resistance as they go.

A Kurzgesagt animation of how the immune system responds to a bacterial infection, depicting immune cells as an army defending the body.

The Thought Emporium shows how easily bacteria can be genetically modified to produce fluorescent proteins and even bioluminesce, with techniques doable at home. It links to companion videos on incubators, DNA extraction and gels.

A very short microscope clip of a neutrophil chasing a Staphylococcus aureus bacterium, originally from David Rogers at Vanderbilt University. It is a widely reposted piece of immune-system footage.

Veritasium visits Richard Lenski's lab to explain the decades-long E. coli evolution experiment, which asks how repeatable evolution is and shows bacteria evolving to use a new food source.

An animated Kurzgesagt explainer on bacteriophages, viruses that kill bacteria, covering how they infect and burst cells and their potential as therapy against antibiotic-resistant bacteria.

Physicist Albert Bartlett's full-length lecture on how steady exponential growth in population and energy use collides with finite resources. It uses examples like bacteria in a bottle and covers peak oil.

Prof. Eran Segal's TEDx talk on research showing that people's blood sugar responses to identical foods vary widely. It describes an algorithm that predicts individual responses and why one best diet for everyone does not exist.
