sporte | May 9, 2008Workforce shortages are a growing problem in the biotech industry. Communities are concerned that a lack of trained workers will either keep companies away or cause companies to move. If companies do have to move, it's likely those jobs might be lost forever, never to return. According to Robert Reich, former U.S. secretary of labor, now a professor at UC-Berkeley, biotech companies that can't hire in the U.S. will recruit foreign workers or open research centers overseas (Luke Timmerman, Seattle PI).
The reason for concern is that biotech jobs, in general, are pretty good. They pay well…
sporte | May 8, 2008Dave Robinson and Joann Lau from Bellarmine College in Kentucky are going to be describing their student project in a free webinar next Friday, May 16th. Their students clone GAPDH (Glyceraldehyde 3-Phosphate Dehydrogenase) genes from new plants, assemble the DNA sequences, and submit them to the NCBI. Here's an example.
Plus, since GAPDH is a highly conserved, it's a great model for looking at evolution.
You can get more information and register here.
The cool thing about plants is that there's lots of material to work with.
gregladen | May 1, 2008A Missouri House Committee has just approved for consideration of the House an Academic Freedom Bill drafted with the aid of the Discovery Institute.
The bill has a nice twist to it in that it prohibits the consideration of any boundary or difference between religion and non-religion in regards to what to teach or how to teach it. In other words, the bill requires that state agencies, school administrators, and teachers ignore the Establishment Clause of the First Amendment of the Constitution of the United States of America in deference to state law. Therefore, challenges to this…
revere | April 28, 2008On a couple of occasions (here, here) we've taken note of the scientific controversy regarding the plasticizer, bisphenol-A (BPA). I shouldn't really put it this way, because as the leading BPA researcher, Fred vom Saal of the Univeristy of Missouri said in the Washington Post over the weekend, there is no meaningful controversy any longer. Now that NIH's National Toxicology Program has finally presented its draft report on BPA expressing concern over possible carcinogenic and developmental effects, vom Saal's statement seems pertinent:
"The scientific community basically said, 'This argument…
gregladen | April 27, 2008With all this talk about Expelled!, the creationist movie, I thought it was about time to resurrect the review I wrote many moons ago of Flock of Dodos by Randy Olson, along with some updated information.
Flock of Dodos is a much better film than Expelled!, and explores the same issue, with somewhat different conclusions. So, for instance, if you are going to use one of them in a school or church to explain the ID/Evolution controversy, I recommend Flock.
(That's a picture of Randy with some big birds at the Tribeca Film Festival.) Plus, since its been out a bit longer, Flock of Dodos is…
sporte | April 26, 2008Over 2600 genetic diseases have been found where a change in a single gene is linked to the disease. One of the questions we might ask is how those mutations change the shape and possibly the function of a protein?
If the structures of the mutant and wild type (normal) proteins have been solved, NCBI has a program called VAST that can be used to align those structures. I have an example here where you can see how a single amino acid change makes influenza resistant to Tamiflu®.
This 4 minute movie below shows how we can obtain those aligned structures from VAST and view them with Cn3D.…
revere | April 24, 2008The art professor is finally cleared but a distinguished biologist was still punished by a ridiculous, mindless, cruel and utterly reckless use of raw power by the Bush administration:
A federal judge dismissed criminal indictments on Monday against an art professor at the State University of New York at Buffalo who was charged four years ago with mail and wire fraud after receiving bacteria through the mail that he said he planned to use in his art projects.
Judge Richard J. Arcara of the U.S. District Court in Buffalo ruled that the indictment against the professor, Steven J. Kurtz, was "…
sporte | April 24, 2008Bill Gates, Eric Lander, Maynard Olson, Leena Peltonen, and George Church fielded questions last night at a fascinating panel discussion on personal genomics at the University of Washington.
We were fortunate to be in the audience. I'll share some of the questions and answers, in some cases shortened and paraphrased.
The room in Kane Hall at the UW was already warm when we arrived last night (yes, I do go to evening seminars). A student handed us cards and cute little pencils for writing our questions and we sat down. We fought the impulse to write "What's the air speed velocity of a coconut-…
gregladen | April 23, 2008But plans for the Institute for Creation Research Masters Degree in Creationistic Biology for High School Teachers is out of Texas.
Members of the Academic Excellence and Research Committee and the Participation and Success Committee voted unanimously to approve the recommendation of Raymund Paredes, the state's commissioner of higher education, not to approve the Institute's application. The full Coordinating Board will vote on the committees' recommendation on Thursday.
"The issue before the Coordinating Board isn't about academic freedom or free speech. The issue is whether the state…
gregladen | April 23, 2008The Institute for Creation Research (ICR) has, some time ago, filed for approval to run a masters degree program in life science education. The purpose of the degree is to train educators to present biology in a way that is consistent with Christian Biblical beliefs, as opposed to actual scientific knowledge. The Texas board in charge of these matters is taking the proposal under consideration this week. (Please sign the petition linked below!)
The Texas Freedom Network has recently conducted a survey of Texas colleges and university faculty to get their opinions on this proposal.
The…
gregladen | April 23, 2008A bill designed to make it easier to introduce creationism into public school classrooms has passed in the Florida Senate by a 21 to 17 vote margin. The bill was proposed by Senator Ronda Storms, Republican, and is modeled after a template provided by the Discovery Institute.
Storms filed the bill shortly after the State Board of Education adopted new science standards that require for the first time the teaching of evolution. That was a controversial decision that upset many residents who argued evolution was unproven, in conflict with their religious beliefs -- or both.
But Storms said…
gregladen | April 23, 2008Despite the fact that the producers of Expelled! have the most nefarious of motives in mind, and that we can expect more from them (we are waiting for the other shoe to drop), it is interesting to note how many conversations this documentary about Intelligent Design Creationism has sparked. Ultimately, the intended purpose of Expelled! is to silence real scientists and set back scientific research that is on the verge of filling one of the most important "gaps" in which the Christian God of the theistic evolutionist currently lives. In the long run, conversations that arise from movies like…
sporte | April 22, 2008One of my favorite web 2.0 technologies is the webinar. When you work at a company and not a University, with constant seminars, it gets a bit harder to hop on a bus and travel across town to learn about new things. Webinars are a good way to fill that gap. I grab my coffee cup, put on my headphones, and I get to listen to someone tell me about their work for an hour and show slides over the web. It's nice.
Our company is even going to be involved in two webinars in the next two months. One of us is giving an Illumina webinar tomorrow on managing Next Generation Sequencing data. A…
jlynch | April 20, 2008Wilkins has a little Aesopian fable that you may want to read.
Still grading, so your Monday Mustelid will be late ... i.e. not on Monday!
gregladen | April 20, 2008Louisiana State Senate Bill 561 is an "academic freedom" bill intended to push discussion of creationism, global warming denialism, and so on into state public schools. This is the latest in a long series of efforts of right wing fundamentalist christians to indoctrinate public school students in their particular religious (and political) beliefs.
In 1981, a law was placed on the books in Louisiana requiring that creationism receive equal time as evolution in public schools. The ACLU challenged the bill, and by 1987 it was struck down by the U.S. Supreme Court because, obviously, it…
sporte | April 17, 2008In the class that I'm teaching, we found that several PCR products, amplified from the 16S ribosomal RNA genes from bacterial isolates, contain a mixed base in one or more positions.
We picked samples where the mixed bases were located in high quality regions of the sequence (Q >40), and determined that the mixed bases mostly likely come from different ribosomal RNA genes. Many species of bacteria have multiple copies of 16S ribosomal RNA genes and the copies can differ from each other within a single genome and between genomes.
Now, in one of our last projects we are determining where…
sporte | April 16, 2008Ribosomes are molecular machines that build new proteins. This process of synthesizing a protein is also known as translation.
Many antibiotics prevent translation by binding to ribosomal RNA. In the class that I'm teaching, we're going to be looking at ribosome structures to see if the polymorphisms that we find in the sequences of 16S ribosomal RNA are related antibiotic resistance.
This is related to our metagenomics project where we investigate the polymorphisms we find in 16S ribosomal RNAs.
This 6 minute video introduces ribosomes, discusses where they're found, what they're made of,…
jlynch | April 13, 2008Just this last week, my daughter had her first AIMS test (Arizona’s standardized test) - an annual week of tests on reading, writing and math. In preparation, all "superfluous" subjects - such as science and social studies - were abandoned in the weeks before hand. Failing students result in failing schools and funding being pulled. So the superfluous gets abandoned and that annoys me.
Equally as annoying is that, in a time where literacy in this country is sub-standard and schools are being forced to teach to the test thanks to the No Child Left Behind act, the Reading is Fundamental…
gregladen | April 13, 2008
The Open Source content management system PLONE runs the newly released NASA Science web site.
The site has something for everyone (researchers, educators, kids, and "citizen scientists"). The Plone seems to be working quite nicely.
Some of it is still a little rough. The Space Calendar link seems to be broken, and the email to the "responsible government official" for the site (who, by the way, is Greg Williams) gets you an email to "noone@nasa.gov" ...
There appears to be a number of distinctly different ways to navigate on this site, including a main in-your-face graphical…
clock | April 12, 2008Being out of the lab, out of science, and out of funding for a while also means that I have not been at a scientific conference for a few years now, not even my favourite meeting of the Society for Research on Biological Rhythms. I have missed the last two meetings (and I really miss them - they are a blast!).
But it is funny how, many years later, one still remembers some posters from poster sessions. What makes a poster so memorable?
I guess it has something to do with one's interests - there is just not enough time during a session to check out every single one out of hundreds (or…
