The problem with research on humans is that everyone wants it, but no one wants to be the guinea pig. Enter cell lines! The problem is that most human cells don’t survive in the lab. In fact, prior to HeLa cells, all cells died within 24 hours or so.
The excellent book by Rebecca Skloot The Immortal Life of Henrietta Lacks, details how the HeLa line came into being, and raises the questions if she should have had consent over what was done with the cells from her tumor. And while I think that it’s misleading to say “Henrietta lived on through her cells” (hence the title of this post), it is worth considering the bioethical quandaries that have resulted from the HeLa lines, and other potential cell lines.
And the new Oprah movie, these questions are likely to be raised again soon.

The World Health Organization announced its first list of antibiotic-resistant “priority pathogens” on Monday, detailing 12 families of bacteria that agency experts say pose the greatest threat to human health and kill millions of people every year.
The list isn’t meant to scare people, but to call attention to microbes for which research into antibiotics is needed.
Read about it at the Washington Post.
Scientists on at MIT are proposing to introduce a mouse that has its genes edited to resist Lyme disease. Given the high prevalence of Lyme disease on the small New England Island, the removal of Lyme disease from the mouse population (who harbor before it infects humans) would then directly effect how prevalent it is in the human population.
But really, this story is about one of the first real world examples of CRISPR, the revolutionary gene editing tool.

In a deeply divided country, some people are dreading going home for the holidays. The anticipation of political conversation, about who voted for who, and about the racist, misogynist bigot who is planning to soon lead the United States.
So instead of talking through some of these issues (although I encourage civil discord!), the New York Times has given us a list of science and health stories from 2016 that you can discuss instead!
You could talk about how science views fat and what we know about weight loss! Or instead of talking about fleeing the country, perhaps consider a move to Mars instead! Or you can talk about dogs, and what science knows about their relationships!
Or you can talk about climate change, funding rates, the importance of teaching evolution and minorities in STEM! Not recommended by the NYTimes but always recommended by NiB.
Also, consider subscribing to the New York Times.
An 8 million dollar study came out in the Lancet ~5 years ago claiming that if you have Chronic Fatigue Syndrome, otherwise known as myalgic encephalomyelitis, the best treatment is exercise and psychotherapy.
However, after years of demanding they release their data (which they did under a court order), it has now been revealed that the study was just plain bad science.
Read about the controversy, the study, and the retraction (hopefully) over at STAT.
Have you recently flown into the US from abroad? On the landing card it asks if you’ve been in contact with things should not be brought into the US.
Have you encountered agriculture or been on a farm?
Have you been exposed to people coughing ebola?
And then one slightly odd question that gets overlooked:
Are you carrying snails? (paraphrasing here)
This is because snails are actuallly really deadly. Or more specifically they are a vector for some really deadly parasites. Read about it, and how to control the snail/parasite spread over at Science Friday.
Male orgasm is pretty easy to figure out. Without it, there is no insemination, so evolutionarily if you can’t get off you can’t make babies. Pretty straight forward.
The female orgasm however is more of a mystery. It is unclear why it occurs (and to some, unclear HOW it occurs).
So the recent research on the evolutionary origin of the female orgasm in The Journal of Experimental Zoology… earth shattering.
Read about the results over at the New York Times!
