Bill 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 ...
A few weeks ago, I did some "back-of-the-envelope" calculations to explain to a reader why genome sequencing costs so much. I estimated that, if JCV's genome were sequenced at the cost advertised by university core laboratories, his genome would cost about $128 million. That was an estimate, of course. But ...
A few months ago I posed some questions about the regulations that might oversee personal genomics companies ( Who's your Daddy? and Step right up, get your very own DNA profile). Why? Because I am biased. At Geospiza, where I work, we make software products that help our customers, who ...
In which I present a quick guide for the omically challenged and a defense of 'arth and "ome." Other SciBloggers have shared their thoughts on the use of ome here and here. Sometimes I get frustrated too, with the way language is abused and tweaked by those around me. So ...
On Sept. 30th, I'm going to be co-presenting a Bio-Link webinar on Genome Engineering with CRISPR-Cas9 with Dr. Thomas Tubon from Madison College. If you're interested, Register here. Since my part will be to help our audience understand the basics of this system, I prepared a short tutorial with Molecule ...
When can a really bad virus be used to do something good? When we can use it to learn. The human immunodeficiency virus, cause of AIDS, scourge of countries, and recent focus of ScienceBlogs; like humans, evolves. As one of my fellow ScienceBloggers noted, few biological systems demonstrate evolution as ...
" Come quickly, Watson," said Sherlock Holmes, " I've been asked to review a mysterious sequence, whose importance I'm only now beginning to comprehend." The unidentified stranger handed Holmes a piece of paper inscribed with symbols and said it was a map of unparalleled value. Holmes gazed thoughtfully at the ...
Replication fork - https://en.wikipedia.org/wiki/Telomere. Organisms with linear chromosomes have to solve the problem that DNA replication makes them shorter. This is due to the fact that DNA polymerase can only add bases to the terminal 3'-OH of a DNA chain. The DNA replication initiation complex uses RNA primers to provide ...
For the past few months, the shake-up that began with Next Generation DNA Sequencing has been forcing me to adjust to a whole new view of things going on inside of a cell. We've been learning things these past two years that are completely changing our understanding of the genome ...
The biotechnology (biotech) industry is incredibly diverse. Recently, I wrote about the size of the biotech industry, which is, of course, related to how biotechnology is defined. As a strict definition, biotechnology is the use of biology to turn raw materials into useful products. However, the act of developing a ...
Razib inspired me to share some of the story behind why white people are considered derivatives. No red herrings, here! Lamason et. al. found a single gene that controls human skin color while studying pigmentation in zebra fish (1). These zebra fish had an unusual golden color that turned out ...
GenomeWeb reports that Rite Aid drug stores on the West coast are now selling kits for doing paternity tests. The kits are made by Sorenson Genomics in Utah. Sorenson Genomics calls it the " peace-mind-test." Really! Each kit contains a swab for collecting cheek cells from the inside of your ...
Ancestry tests aren't just for humans anymore. We went to Petco this weekend to buy dog food and found brochures for doggy DNA testing. Now, those of you with dogs of uncertain parentage need puzzle no longer. According to Petco, their SNP test ( what is a SNP?) can identify ...
One of the interesting things I learned today was that many people are calling for the genome sequences of the chimps and Macaques to be finished. This is especially amusing because the human genome isn't quite done. We're primates, too! Why not finish our genome? [I blame these new-found revelations ...
One of my readers asked: Why does genome sequencing cost so much? My short answer is because it's big. But I thought it would be fun to give a better answer to this question, especially since I'm sure many of you are wondering the same thing. Okay, so let's do ...
Lots of bloggers in the DNA network have been busy these past few days writing about Google's co-founder Sergey Brin, his blog, his wife's company ( 23andme), and his mutation in the LRRK2 gene. I was a little surprised to see that while other bloggers ( here, here, here, and ...
An NSF post on Twitter this morning described an interesting study from the University of Pennsylanvia and Cornell University, that found that some people who call themselves "African Americans" may only be 1% West African, according to their DNA. The University of Pennsylvania press release contains other interesting findings as ...
