I read this morning (link) that Tan Jiazhen, better known in the U.S. as C. C. Tan, passed away Nov. 1, at age 99. I suspect that his influence on genetics probably much greater than most Americans appreciate. He goes back to he first flowering of Drosophila genetics, when he was Dobzhansky's first Ph.D. student at Cal Tech, yet many of the young Chinese scientists coming to the United States now have met him. It's impossible for me to evaluate how much he is responsible for the intellectual "silk road" that contributes so much vitality to twenty first century genetics, but I suspect that without C.C. Tan it would be much less traveled. Interested readers should consult Jim Crow's commentary in genetics (Vol. 164, pg. 1 *) to see how he managed to bring Chinese genetics into the modern era, past the Lysenko years and the Cultural Revolution.

No matter what they say, DNA Dynasty will not and cannot tell you what your “kids (sic) innate talent” is via “DNA discovery.”
National Society of Genetic Counselors President Angela Trepanier would agree. From her interview with Karen Kaplan of the Los Angeles Times:

Well, just adding my two cents to the pissed off blogosphere regarding a company in Singapore called DNA Dynasty. Not only are they purveying complete crap in terms of genetics/genomics (e.g., they say they have a genetic test to determine the innate abilities of your children) but they have apparently stolen the logo of the DNA Network of which I am a member. Lovely. I figure, if we make enough blogging noise, then when people search for them with google they will at least also see some of our postings. So here is mine. See also

Those of you who read this blog or others that discuss non-coding DNA will, for better or worse, be familiar with regular commenter Andras Pellionisz. Many people have concluded that Dr. Pellionisz is essentially a "crank", though I believe I have tried to give him a fair hearing on this blog (before asking him to stop repeating the same arguments over and over). Whether he has managed to convince anyone of his view that all non-coding DNA is functional is another issue, however. Readers should judge this for themselves. Thus, here are links to his website, a recent article, and a recent Google Tech presentation.

I don't get too concerned about things such as titles, but I have noticed that this year a more substantial number of students has been sending emails addressed to "Mr. Gregory". I don't know if the students this year are unaware that most professors hold a Ph.D. and therefore are "Dr." and not "Mr." (or "Ms." as the case may be), but this seems to be much more common lately. Has anyone else noticed this?
I know this can get a bit confusing, so let me try to explain it, at least as the terms are used in North America.
The title "Doctor" and the abbreviated prefix "Dr." come from the Latin for "teacher", and are traditionally bestowed on those who have earned the highest academic degree attainable. The suffix Ph.D. is an abbreviation for Philosophiæ Doctor (L. "Teacher of philosophy"), with "philosophy" from the Greek for "love or pursuit of wisdom". The Ph.D. is awarded in most academic disciplines, including science. Medical professionals may also hold the title "Doctor" even though they may do little or no teaching, with common degrees being M.D. (Medicinae Doctor, or Doctor of Medicine), D.V.M. (Doctor of Veterinary Medicine), D.D.S. (Doctor of Dental Surgery), and so on.
As a noun rather than a prefix, "Doctor" is usually reserved for medical doctors ("I'm not a doctor but I play one on TV"). Usually, the person teaching your course at a major university is a "Professor" and not a "Doctor" (noun) ("Are you really a mad scientist, professor?"). He or she does, however, use the prefix "Dr.". Get it?
To make it more complex and Monty Python-ish, the prefix "Prof." is not used by all professors. "Professor" (noun) is the position, but there are also ranks. In North America, these would be "Assistant Professor", "Associate Professor", and "Professor" (or "Full Professor"). In many cases, only full professors use the prefix "Prof." in situations outside the university. I don't use "Prof. Gregory" in non-university settings because I am not a full professor. However, I am a professor, not a doctor, although I use Dr. Gregory instead of Prof. Gregory. Right.
Perhaps that's all too complicated to bother about. Here is the short version: When addressing a professor, just go with "Dear Dr. So-and-so" unless he or she asks you to call him or her something different.
