  • TED - Tal Danino: We can use bacteria to detect cancer (and maybe treat it) (0:04:16)
  • NUUG
  • Liver cancer is one of the most difficult cancers to detect, but synthetic biologist Tal Danino had a left-field thought: What if we could create a probiotic, edible bacteria that was "programmed" to find liver tumors? His insight exploits something we're just beginning to understand about bacteria: their power of quorum sensing, or doing something together once they reach critical mass. Danino, a TED Fellow, explains how quorum sensing works — and how clever bacteria working together could someday change cancer treatment. TED talk downloaded from The Internet Archive.
  • TED - Maryn McKenna: What do we do when antibiotics don’t work any more? (0:17:04)
  • NUUG
  • Penicillin changed everything. Infections that had previously killed were suddenly quickly curable. Yet as Maryn McKenna shares in this sobering talk, we've squandered the advantages afforded us by that and later antibiotics. Drug-resistant bacteria mean we're entering a post-antibiotic world — and it won't be pretty. There are, however, things we can do ... if we start right now.
