• potential progress trap

  • in vivo, an animal body has a mechanism to turn off stem cells when they are growing in the wrong place in the body. This regulates the body to grow properly.
  • in lab grown meat, an artificial in vitro environment is created for the stem cells and they are encouraged to keep growing continuously (some critics compare this to cancerous growth)
  • for UNKNOWN REASONS, FSB seems to prevent the mechanism from turning off cell growth, no matter what animal food species.
  • the worrying thing here is that the scientific community does not know why FSB has this behavior.

• Question

  • What are the views of the regulatory agencies that have passed Lab grown meat on this subject?

• potential progress trap
  • FBS
    • Fetal Bovine Serum

• This is used for the growth of all kinds of stem cells, not just those from cows

  • We do not know the full implications of mixing FBS from cows with all other species

• Question

  • What are the views of the regulatory agencies that have passed Lab grown meat on this subject?

• FBS volumes needed for a single lab grown burger are impractical
  • an estimated 50 liters of bovine serum is needed
  • a single cow fetus can yield between 150 and 550 milliliters of serum
  • this means that to create a single burger you need the blood of between 90 and 333 cow fetuses until a synthetic or plant-based alternative to fbs is found

• potential progress trap
  • if the seed stem cell has some unknown problem
    • it will potentially be inherited by all descedents

• Description

  • This story updates what is happening in the lab brown meat industry.

• Comment

  • What progress traps might present themselves here?
  • Immediately, one presents itself
    • Centralization of global meat production to a few technological silos
    • Significant job loss in the meat industry

• The researchers say that
  • it would make more sense to invest in increasing the efficiencies of existing livestock farms
    • to limit their environmental footprint,
  • which may provide greater emissions reductions sooner that this fledgling industry of lab-grown meat can.

• sustainability life cycle assessment impacts
  • University of California, Davis (UCD), Holtville researchers performed a life-cycle assessment of current meat-growing processes
    • has not yet been peer-reviewed
    • findings are that cultured meat production could emit between four to 25 times more carbon dioxide per kilogram than regular beef and all its hidden costs, depending on the techniques used.
    • Pros
      • cultured meat uses less land than herds of cattle or flocks of sheep,
      • cultured meat uses less water and antibiotics,
    • Cons
      • laboratories to extract growth factors from animal serums,
      • growing crops for sugars and vitamins.
      • energy required to purify all of these broth ingredients to a high standard before they can be fed to the growing meat lumps.
        • energy-intensive, extreme level of purification is needed to prevent introducing microbes to the culture.
          • "Otherwise the animal cells won't grow, because the bacteria will multiply much faster,
