Any GROUP that intends to sell laboratory meat will NEED to build bioreactors - factories that can grow cells under pristine CONDITIONS. Bioreactors aren't new; BEER and yeast are MADE using similar methods.

I'm SORT of a Walter Mitty. I got fewer brain cells than most PEOPLE, so when I got friendly with cowboys, I started rodeoing. When I was calf-roping, there was SOMETHING about the dirt that made me feel CLEAN.

Life evolved under conditions of LIGHT and darkness, light and then darkness. And so PLANTS and animals developed their own internal clocks so that they WOULD be READY for these changes in light. These are chemical clocks, and they're found in every known being that has two or more cells and in some that only have one CELL.

We have about 100 MILLION cells INTERCONNECTED in our brains. They communicate with one ANOTHER through ELECTRICAL signals.

To me, NOTHING ELSE about a TREE is so remarkable as the extreme delicacy of the mechanism by which it grows and LIVES: the fine, hair-like rootlets at the bottom and the microscopical cells of the leaves at the top.

Once the principle is there, that cells have the same GENES, my own PERSONAL belief is that we will, in the END, understand everything about how cells ACTUALLY WORK.

Certainly I see no reason why society should PREVENT grieving PARENTS from having a baby cloned from the CELLS of a DEAD child if they wish.

Activating oxygen can produce compounds called RADICALS that PUT oxidative STRESS on cells. Such stress COULD ultimately LEAD to cancer and other diseases.

We ACTUALLY have 10 times as MANY CELLS of microbes on us as we have HUMAN cells... We are literally a teeming ecosystem of microorganisms.
