Thanks to a tip from ChemBark et al., here is the most “insanely irresponsible” promotion of hazardous chemistry demos that I’ve seen. Written by Gizmodo Contributing Editor Eric Limer, the post draws from books by author William Gurstelle (Backyard Ballistics, Absinthe & Flamethrowers).
On one hand, Gurstelle has done much to promote scientific curiosity among the public. That’s a good thing. Plus, Gurstelle has safety glasses in his promo picture. But Limer takes some of Gurstelle’s ideas out of context and suggests that they be used to scare or harm others.
Thankfully, many commenters have gone over to Gizmodo to register their disapproval but the post remains up. I understand from his profile and website that Limer lives in an area hit by Hurricane Sandy but I encourage him to take down his hurtful post as soon as is feasible.
Quirky is fun and interesting and people can find this information elsewhere with a little work. But promoting it at a major geek site is a Bad Idea.
Our best wishes to all of you in the Northeast getting ready for Hurricane Sandy. I understand that even DC is closed today. So if you still have power at home, let me share a bit of levity with you.
Over the weekend I learned that my science writing student, Meghan Radford (@meradfor), had a clever piece published at mental_floss, the magazine and website, “where knowledge junkies get their fix.”
Megan’s article entitled, “18 Gene Names that Cover the Gamut, From Movies to Pop Culture to Cartoons,” illustrates the comical yet discordant and unscientific process behind naming genes.
I’m not familiar with any genes that are named after the person who discovered them but, as Radford points out, a great many have been given interesting colloquial names. International gene nomenclature organizations exist but the standardized rules of these committees still make refer to the less formal names.
To celebrate National Chemistry Week, the esteemed synthetic chemist blogger See Arr Oh put out a call for folks to describe to younger folks how they got where there are in the broad field of chemistry:
What do you do all day? What chemistry skills do you use in your line of work? How do you move up the ladder in chemistry? What do I need to do to be in your shoes?
The resulting answers from other bloggers — and any respondents, for that matter — will be compiled at his blog, Just Like Cooking, in what’s called a blog carnival. Specifically, contributors to blog carnivals are asked to respond to a theme or a series of questions. In this particular case, we are tagging our posts with the hashtag, #ChemCoach.
Here’s the list and below are my responses. You may find it helpful to play this Talking Heads video while reading my answers.
Your current job.
What you do in a standard “work day.”
What kind of schooling / training / experience helped you get there?
How does chemistry inform your work?
Finally, a unique, interesting, or funny anecdote about your career*
The most important question to ask yourself - If I were just coming into the field, would I learn something useful from your story?
I’m not an architect but I absolutely love quirky and creative buildings. During the eight years I lived in the foothills outside of Denver, I passed the clamshell-shaped home featured in Woody Allen’s 1973 movie, “Sleeper” – yes, the home with the Orgasmatron (a prop made from a cylindrical door like those used for research darkrooms).
For you youngsters who may not know what I’m talking about, here’s a two-minute movie clip that’s probably safe for work.
Well, from that era is another futuristic building designed by Paul Rudolph and completed in 1971 — then known as the Burroughs-Wellcome Headquarters Building in Research Triangle Park.
Among my delightful experiences at Duke last Wednesday with the laboratory of Bob Lefkowitz was a particularly humorous moment I witnessed when two scientists burst out from the lab’s reception and one said, “Back to lab. We have to win the second one!”
I had to chase them down the hall to ask a few questions.
It’s unedited but I had a good time talking with these gents.
* yes, I know, I made the picture worse by having them stand under the light.
How many of you could say this about your laboratory group?
In the hall outside the champagne reception for Bob Lefkowitz’s lab on Wednesday at Duke University Medical Center, I had a chance to catch up with Marti Delahunty, PhD. Delahunty is a research scientist in a connecting building but worked in the Lefkowitz group from 1998 until 2006.
This brief chat brings to mind Carmen Drahl’s post about one’s laboratory being your second family.
PIs, trainees, technicians, and administrators: Tell me if you’d be able to say the same about the environment of your laboratory.
As discussed in my previous post, I took a personal day off from work yesterday to bask in the excitement of a university community celebrating a Nobel prize for one of its most beloved researchers, Dr. Robert “Bob” Lefkowitz, MD. He joined Duke in 1973 when, he says, “it was not the powerhouse it is today.”
Lefkowitz will share the prize with his former trainee, Brian Kobilka, MD, now at Stanford University.
I had the honor of joining his laboratory’s champagne celebration in the morning and the Duke University press conference in the early afternoon. (The full 47-minute press conference streamed live and is archived here at Duke.).
I live barely three miles from Duke and had no idea when or if I’d ever have the chance to be so close to such an event. The Lefkowitz prize is particularly meaningful to me as he is a biochemist physician-scientist who also considers himself a pharmacologist. So, I write this not so much as a journalist but rather — as Duke Research Communications Director Karl Leif Bates put it — a fan boy.
Defending the Chemistry Nobel for “biology” – again.
I’m near-certain that this is the first Nobel Prize in Chemistry given to two MDs. (10:31 am EDT: I was wrong, as per commenter Jonny below. Peter Agre, MD, and Roderick MacKinnon, MD, received the Nobel Prize in Chemistry 2003 for their work on aquaporins and other ion channels.)
Robert Lefkowitz, MD, of the Howard Hughes Medical Institute and Duke University Medical Center, and Brian Kobilka, MD, of Stanford University School of Medicine, will share the Nobel Prize in Chemistry 2012. The award recognizes a lifetime of work, certainly for Lefkowitz, in elucidating the action of the central chemical signal transducers of the human body.
This is a chemistry prize, albeit a biological chemistry prize.
The prize is being given for discovering how the body’s most important chemicals communicate their own chemical signals from outside the cell to inside. Without G-protein-coupled receptors, or GPCRs, our hearts would not beat, our lungs would not expand and contract, and our brains would be unable to regulate much of everything that runs in our bodies.
Moreover, the ubiquity of GPCRs have over history breathed tremendous life and stimulated innovation in chemistry to synthesize tools to modulate these receptors and thereby relieve human suffering. Chemists should revel in this prize – without G-protein coupled receptors, many chemists would not have been employed for the last few decades.
But I do agree that a case could be made for this prize to be given in Physiology or Medicine, particularly since GPCRs are central to physiology, “from plants to man.”
Feel free to vent your spleen in the comments below.
But do note that Derek Lowe, medicinal chemist and grand master of the chemblogosphere, has already decreed, “[M]y fellow chemists, cheer the hell up already.”
Disclosure: I hold an Adjunct Associate Professor appointment in the Duke University School of Medicine, Department of Medicine.
British scientist John B. Gurdon and Shinya Yamanaka (MD, PhD!), a Japanese scientist now at the Gladstone Institutes in San Francisco, were awarded the Nobel Prize in Physiology or Medicine this morning, ”for the discovery that mature cells can be reprogrammed to become pluripotent.”
Briefly, Gurdon and colleagues showed that the genetic information from a mature, differentiated cell still had the ability to program an undifferentiated embryonic cell to develop into an adult organism. That is, an embryonic cell contains the chemical signals to use adult DNA to drive development of a new organism.
The work was done with the frog, Xenopus laevis, and the technique came to be known as “nuclear transfer.” In colloquial terms, this is “cloning.” Current press reports are citing Gurdon’s work as occurring in 1962 but studies appear to have been published in Nature as early as 1958.
Christen Brownlee composed a superb summary of nuclear transfer for the Classics section of the Proceedings of the National Academy of Sciences. Gurdon’s work stemmed from 1952 experiments of Robert Briggs and Thomas J. King with another frog, Rana pipens. Briggs died in 1983 and King in 2000 and could not be recognized with the Nobel. This fact relieved the Nobel committee, in my opinion, from having to decide which scientist would have been awarded the potential third slot for the prize. (Addendum 7:18 am EDT): I suspect that some argument will arise in support of UW-Madison’s James A. Thomson for the third slot as the Science paper from his group came out concomitantly with Yamanaka’s Cell paper. 8:21 am: The Guardian’s Alok Jha just reminded me that I overlooked Takahashi and Yamanaka’s earlier Cell paper from 2006. However, C&EN’s Carmen Drahl is now reporting this 2001 TIME magazine cover with Thomson.)
