What if you were holding life-saving medicine … but had no way to administer it? Zoom down to the nano level with engineer Kathryn A. Whitehead as she gives a breakdown of the little fatty balls (called lipid nanoparticles) perfectly designed to ferry cutting-edge medicines into your body’s cells. Learn how her work is already powering mRNA-based COVID-19 vaccines and forging the path for future therapies that could treat Ebola, HIV and even cancer.

    “These vaccine allergies COULD be caused by something other than PEG (polyethylene glyco) more research is needed to get to the bottom of these side effects”

      @Δ.Μ i just quoted her exact words, how can that be taken out of context when I did not give an opinion on the statement??!?!???

      @Rules
      Dude… Do you know what the word context means?

      August 11, 2021 at 4:21 pm

      @Δ.Μ so is more research needed to see if polyethylene glyco (PEG) causes side effects or not?? Or could you please put the statement into “context” for me?

      @Rules I was of the belief that Pegs were carcinogenic? That it was a proven fact?

    If there is a way to have the body destroy cancer cells that’s great. But does it stop the reason why cancer cells are being created in the first place. Can your body go cookoo because its creating and killing a particular cell at the same time? Will the cancer come back stronger if that’s possible? Or is cancer just one strength fits all. seems like these cells have the will to survive and over come their killers. When cells are invaded by virus can it evolve the ability to protect itself and at the same time protect the virus? What triggers defense and evolution in a cell, and does that defense differ from a cell with a virus?. Very interesting stuff. If a particular virus effects cells of a vital organ then time is of the essence or one will die? How many known and unknown virus are there? Do these virus and bacteria effect plants and animals which are the food we eat? Do we eat virus and bacteria? Is eating virus and bacteria a good thing? Why does certain bacteria and virus effect some but not others? Does pollution and climate change weaken immune systems of plants, animals and humans? Giving the bacteria and viruses to a host via any means seems to help them evolve and devolve. Seems scary if a bacteria or virus finds the ability spread and kill quickly. Does it want to spread and kill quickly of is it just taking advantage of an abundantly exploitable environment? Are humans an virus says the matrix?

    Excellent presentation with measured, understandable, informative information. The analogy of packaging is brilliant. I’m going to share with those who are still not vaccinated.

    the reason they dont want to license them is cause they dont want other companies to get in the game

    Got too technical mid-way for me.

    I agree with Maya Rudolph but why is she giving a TED talk on this subject?! ????????

    Well , this make me wondering which was the cause which was the solution , and what if pandemic was needed to push science forward. Playing at level of DNA with our immune system is like trying to regulate the climate- too difficult to our knowledge, too much risk on the side of it.

Mark Zuckerberg Has a Question for AI Doomers
