pharyngula | July 21, 2009
PLoS has recently published a highly speculative but very interesting paper on how a particular signaling pathway, the Hedgehog pathway, might have evolved. It's at a fairly early stage in hypothesis testing, which is one of the things that makes it interesting — usually all you see published is the product of a great deal of data collection and experiment and testing, which means the scientific literature gives a somewhat skewed view of the process of science, letting the outsider mainly see work that has been hammered and polished, while hiding the rougher drafts that would better allow us…
drorzel | July 21, 2009(On July 16, 2009, I asked for volunteers with science degrees and non-academic jobs who would be willing to be interviewed about their careers paths, with the goal of providing young scientists with more information about career options beyond the pursuit of a tenure-track faculty job that is too often assumed as a default. This post is one of those interviews, giving the responses of Nicole Leuke, a science teacher in Alberta.)
1) What is your non-academic job?
I am a High School Science and math teacher. I teach primarily physics and general sciences (grades 10,11,12). I have been teaching…

drorzel | July 20, 2009The Internet has been all abuzz today over the anniversary of the Apollo 11 landing. Tor has the best one-stop collection of reminiscences, but there are plenty of others. They're roughly equally split between "Wasn't that the coolest thing ever?" and "Isn't it a shame we stopped going.
I was a bit over -2 when the Moon landing happened, so I have no personal recollections to offer. It's a significant enough anniversary for a geek like myself, though, that I wouldn't want it to pass completely without comment.
Personally, while I have some sympathy for the laments that we stopped sending…
catdynamics | July 20, 2009"My son and I stand beneath the great night sky
And gaze up in wonder
I tell him the tale of Apollo And he says
"Why did they ever go?"
It may look like some empty gesture
To go all that way just to come back
But don't offer me a place out in cyberspace
Cos where in the hell's that at?"
B.B.
I had to look something up on nasa.gov earlier today, and was met with the grainy footage of an astronaut descending the ladder to the lunar surface, exactly 40 years ago today as I start typing this, thanks to the "flash" script that grabbed my browser as I entered the site.
I hadn't forgotten, just not…

drorzel | July 20, 2009Last week's call for non-academic scientists produced a much larger response than I was expecting-- more than 30 people volunteered. Thanks to all who volunteered, and if you're interested, please feel free to contact me-- it's not too late to get involved.
As I said in that post, I plan to post a series of short interviews with people who have science degrees, but are not working in academia. The idea here is to provide information on career options for scientists and science majors beyond the "go to grad school, do a post-doc, get a faculty position" track that is too often assumed to be…
drorzel | July 20, 2009I'm watching an episode of NOVA scienceNOW (eccentric capitalization makes it hip!), and Neil deGrasse Tyson is doing a segment on extrasolar planets. I'm only half listening, because I'm also trying to keep SteelyKid from trying to eat any of the furniture, but it's quite good.
All of a sudden, Emmy's head snaps up. "Hey!" she says. "He owes me a cookie!"
"What?" I ask. "Who owes you a cookie?"
"The human on the tv. He was just explaining science using dogs. Inferior dogs. That's my job!"
"Technically, it's my job. I'm the one who does all the writing, after all." I rewind the DVR a bit to…

The Grand Canyon is such an icon of the Earth's geological history, of slow and steady uplift, erosion, submergence and deposition, that the creationist crowd thought it essential to tackle it head on. So they have come up with an explanation as to how it might have got there in a world created only 6,000 years ago. Their attempts to squeeze this majestic testament to natural processes into bronze age mythology are not just clumsy, they're the stuff good comedy is made of [10:03]
drorzel | July 19, 2009Kate and I will both be on programming at Anticipation, the upcoming Worldcon in Montreal. The official program should be up on the web soonish, but I got my schedule by email, and figured I would post it here for those who care:
When: Fri 10:00
Title: How to Effectively Talk about Science to Non-Scientists and
Why it Matters
Description: Presenting one's ideas is ever more crucial for
scientists. If we don't do it well, you can be certain someone else
will do it badly.
(This will be a slightly reconfigured version of the talk I gave at the Science21 meeting last fall.)
When: Sat 10:00…
emjohnson | July 19, 2009Jorge Cham has just posted his latest PhD Comic, this one taking on the rivalry between Nature and Science. Look behind the scenes at how the science publishing industry REALLY works. It's enough to make you want to publish only in PLoS ONE!

"How does one distinguish a truly civilized nation from an aggregation of
barbarians? That is easy. A civilized country produces much good bird
literature."
--Edgar Kincaid
The Birdbooker Report is a special weekly report of a wide variety of science, nature and behavior books that currently are, or soon will be available for purchase. This report is written by one of my Seattle birding pals and book collector, Ian "Birdbooker" Paulsen, and is edited by me and published here for your information and…
pharyngula | July 17, 2009It's sad to see that we've lost Brian Goodwin, one of the genuinely original (but not always right!) thinkers of our time. There aren't many left of the old structuralist tradition in biology, the kind of non-genetic purists who tried to analyze development in terms of the fundamental physical and chemical properties of the organism—they've been swallowed up and lost in a triumphal molecular biology research program.
Edge has a nice interview with and essay by Goodwin — they're good places to start. If that whets your appetite, you should also read his book, How the Leopard Changed Its Spots…
bioephemera | July 17, 2009Janet has a very interesting post over at Adventures in Ethics, springboarding off Chris Mooney & Sheril Kirshenbaum's new book Unscientific America. She discusses a key concept that seems obvious, but constantly ends up being ignored by both pro-science and anti-science factions: scientists are not a monolithic interest group. (For one thing, we disagree about how and when to approach the public, and how conciliatory to be).
Janet says,
I think it's fair to say that scientists and other members of Team Science are not in total agreement about which segments of the public can be…
drorzel | July 17, 2009I've been really surprised at the number of people writing about Unscientific America who are confused by the discussion of the Pluto incident (Mad Mike is the latest, but it's not hard to find more). For those who haven't read the book, the first chapter opens with a description of the public reaction to the decision by the IAU to demote Pluto from a "planet" to a "dwarf planet."
I didn't think the point of this was all that difficult to figure out, but it seems to have created a great deal of confusion. Some of this is probably disingenuous, but a number of people seem to be genuinely…
pontiff | July 16, 2009A friend sent me a link to Detextify2:
What is this?
Anyone who works with LaTeX knows how time-consuming it can be to find a symbol in symbols-a4.pdf that you just can't memorize. Detexify is an attempt to simplify this search.
How does it work?
Just draw the symbol you are looking for into the square area above and look what happens!
My symbol isn't found!
The symbol may not be trained enough or it is not yet in the list of supported symbols. In the first case you can do the training yourself. In the second case just drop me a line (danishkirel[[[at]]]gmail.com)!
I like this. How can I help…
pontiff | July 16, 2009Via @mattleiffer, viXra.org:
In part viXra.org is a parody of arXiv.org to highlight Cornell University's unacceptable censorship policy. It is also an experiment to see what kind of scientific work is being excluded by the arXiv. But most of all it is a serious and permanent e-print archive for scientific work. Unlike arXiv.org tt [sic] is truly open to scientists from all walks of life.
Maybe I should submit one of my papers with all of the text reversed (yeah, yeah, it would still be incomprehensible.)
