Mystery Seed of the Week 181

We’re back to Arizona this week.

Okay, so we did a relative of this plant not too long ago, but I just had to share this photograph.

Do you know what plant these came from? If you’d like to, please leave a comment with your idea.

Edit:  The answer is now posted.

Seed of the Week: Pignut Hickory

Our mystery nuts last week were not from the shagbark hickory, but from the the pignut hickory, Carya glabra.

Pignut hickories are large trees, commonly part of the mixed hardwood deciduous forest in the eastern United States.

Pignut hickories are native trees.

Like their relatives, the leaves are compound.

The nuts within the reverse-pear-shaped fruit are said to be bitter. Some wildlife will eat them, but we noticed it was a lot harder to find shagbark hickory nuts on the ground in the same area. I have a feeling, the shagbark nuts were being consumed first.

Do pignut hickories grow where you live?

For the Good of Mankind? Blog Tour

Today’s STEM Friday book is not our usual fare. In For the Good of Mankind?: The Shameful History of Human Medical Experimentation, author Vicki Oransky Wittenstein for-the-good-of-mankindhas gathered horrific examples of medical experimentation performed on people without their knowledge or consent. Although you might expect the cases to be largely from previous centuries, the sad truth is that Wittenstein has uncovered examples right up to the present day.

Note: If you are squeamish, you should probably stop reading right here.

Wittenstein starts the book with the outrageous story of Simeon Shaw, a four-year-old Australian boy who developed bone cancer in 1946. With a great deal of fanfare and publicity, the boy and his mother were brought to the University of California Hospital in San Francisco for treatment. Unbeknownst to most people involved, including Simeon’s mother, he was injected with radioactive materials instead and his tissues were harvested to study the movement of radioactive materials in the human body. Simeon was sent back home without receiving any actual cancer treatment and died months later.

The author sticks to her thesis about the conflict of medical experimentation and patient’s rights for the rest of the book, digging out case after case of painful, often fatal, medical experiments carried out against the patient’s best interest and mostly without informed consent. Accounts range from the words of a survivor of Dr. Mengele’s concentration camp experiments to the more recent Trovan experiment in Nigeria, where certain participants were given the unproven drug Trovon to cure their meningitis instead of an antibiotic that was known to work.

Some of the case histories felt like they needed a bit more perspective. Why did  the doctors in California want to perform experiments with radiation on a small, sick boy? Why couldn’t they have used an animal model? Unless the reader is an ardent student of history who understands the time period, it feels like the historical context, experimenter’s motivations and even the outcomes have not been described fully enough.

For example, Edward Jenner tested the idea behind smallpox vaccine by giving his gardener’s young son cowpox and then purposely exposing him to smallpox without the boy’s knowledge. It seems atrocious to purposely infect a small boy with a potentially fatal disease. What is not mentioned in the book, however, is that others had already conducted successful experiments using cowpox to create immunity against smallpox and Jenner had every reason to believe he would also be successful. It would not be difficult to include numbers as to how many people were dying from smallpox at the time (20% of the population according to one source) and how many lives were saved by the vaccine, but that is not revealed.

Does establishing that there might have been some benefits – or at least compelling reasons for the inhumane experiments – somehow negate or justify the wrongfulness of the procedure? To my mind, it does not. I think, however, that being able to more fully examine the experimenter’s actions based on the information available at the time does help add important historical context that might allow researchers and policy makers to avoid similar patterns of thinking in the future, such as what boundaries regarding personal freedoms and human decency should be safeguarded when a country is at war.

Regarding safeguards, the author shows that we have made significant advancements in the area of medical ethics over time. As modern techniques take our abilities into the realm of science fiction, we need to make sure policies remain in place to protect individuals, and particularly the most vulnerable ones, from the types of cruel treatments in the name of medical advancements the author has uncovered.

Obviously, this is a thought-provoking book. For the Good of Mankind?: The Shameful History of Human Medical Experimentation is likely to leave the reader with many tough questions to ponder. It is probably best for mature young adult readers interested in medical history and ethics.
