A Quote by Rebecca Skloot
Only cells that had been transformed by a virus or a genetic mutation had the potential to become immortal.

Cancer cells have had so many other things go wrong with them, genetic, non-genetic changes, that those cells, one of the things they then get selected for is that they have lots of telomerase because now the telomeres in those cells get maintained.
Henrietta Lacks' cells are immortal. They are known as the HeLa cell line, and they have become deeply involved in all sorts of medical and genetic research - sometimes in the most unexpected ways.
The unique nature about the influenza virus is its great potential for changes, for mutation.
Something that had been a single cell, a cluster of cells, a little sac of tissue, a kind of worm, a potential fish with gills, stirred in her womb and would one day become a man--a grown man, suffering and enjoying, loving and hating, thinking, remembering, imagining. And what had been a blob of jelly within her body would invent a god and worship; what had been a kind of fish would create, and, having created, would become the battleground of disputing good and evil; what had blindly lived in her as a parasitic worm would look at the stars, would listen to music, would read poetry.
Outside, in the newly fallen darkness, the world had been transformed. The sky had become a glistening tapestry of stars.
We have Borna virus genes. We're part Borna virus, which is weird, but apparently our cells and our genomes in a weird way might actually be grabbing these viruses, grabbing genetic material from the viruses that are infecting it and pulling them into their own genome.
On the morning of May 1, 2018, I woke up knowing that the day I had anticipated for nine years had finally arrived. It was the day of my preventative double mastectomy - the day I would attack my BRCA 2 genetic mutation head-on and take my chances of breast cancer from 84 percent to virtually zero.
My wife and I had been to the genetic counselor; my wife is not Jewish - she's the shiksha goddess type - and was negative for everything. But I was positive. I carried the gene for three genetic disorders, which, if she had been positive for, we would have passed down to the child.
Both in Britain and America, huge publicity has been given to stem cells, particularly embryonic stem cells, and the potential they offer. Of course, the study of stem cells is one of the most exciting areas in biology, but I think it is unlikely that embryonic stem cells are likely to be useful in healthcare for a long time.
I finally knew... why Christ's prayer in the garden could not be granted. He had been seeded and birthed into human flesh. He was one of us. Once He had become mortal, He could not become immortal except by dying. That He prayed the prayer at all showed how human He was. That He knew it could not be granted showed his divinity; that He prayed it anyhow showed His mortality, His mortal love of life that His death made immortal.
If cathedrals had been universities If dungeons of the Inquisition had been laboratories If Christians had believed in character instead of creed If they had taken from the bible only that which is GOOD and thrown away the wicked and absurd If temple domes had been observatories If priests had been philosophers If missionaries had taught useful arts instead of bible lore If astrology had been astronomy If the black arts had been chemistry If superstition had been science If religion had been humanity The world then would be a heaven filled with love, and liberty and joy
Thus much indeed he was obliged to acknowledge - that he had been constant unconsciously, nay unintentionally; that he had meant to forget her, and believed it to be done. He had imagined himself indifferent, when he had only been angry; and he had been unjust to her merits, because he had been a sufferer from them.
This year, 1996, has been designated the 'Year of the Vaccine,' commemorating the 200th anniversary of Edward Jenner's vaccination of James Phipps with cowpox virus and subsequent challenge with smallpox virus. Insight into the nature of viruses, and how viruses interact with mammalian cells, has evolved since the turn of the century.
She had been dying so long that I had almost come to regard her as immortal.
What seems to be clear to me is that after the primary infection most of the cells die indirectly, but at the later stage, when the viral load is very high, the virus kills a lot of cells directly.
It's the advantage of the virus to spread, and you can only spread when you infect people and they infect other people without necessarily killing them. So if you had 100 percent mortality, the potential pandemic would almost self-eliminate itself.
