We've had some recent trouble with our TV service. Several programs did not record well and had freezes and pixilation. The problem wasn't the same as when satellite service is interrupted by weather issues. All this happened after a new receiver was installed so we were confused as to what to do. Our provider sent a tech to check out the problem but didn't leave a note (we weren't home when he stopped by). The next day, as we were having lunch, a pair of techs knocked on the door. One of the techs was from Chicago, someone who apparently has more experience, and he did make a few changes in the set up and now we seem to have better reception.
A week ago we enjoyed a free preview weekend on HBO and recorded the Oprah Winfrey movie "The Immortal Life of Henrietta Lacks." I had just read about the movie and thought it was fortunate that we could get a free showing. According to what I learned at Wikipedia.com Henrietta died in 1951 and her cancer cells were the source of the HeLa cell line, the first immortalized cell line and one of the most important cell lines in medical research. An immortalized cell line will reproduce indefinitely under specific conditions, and the HeLa cell line continues to be a source of invaluable medical data to the present day.
George Otto Gey, the first researcher to study Lacks's cancerous cells, observed that her cells were unique in that they reproduced at a very high rate and could be kept alive long enough to allow more in-depth examination. Until then, cells cultured for laboratory studies only survived for a few days at most, which wasn't long enough to perform a variety of different tests on the same sample. Lacks's cells were the first to be observed that could be divided multiple times without dying, which is why they became known as "immortal."
The ability to rapidly reproduce HeLa cells in a laboratory setting has led to many important breakthroughs in biomedical research.
As mentioned in the opening sentence, we've had lots of rain and now as I head for bed on this Sunday evening many of the surrounding counties are under a flash flood watch. I know we won't float away, but I do hope and pray that anyone living in a low lying area will be safe and not suffer major flooding.
