I’m a big of learning from data. There are many things we can learn about swine flu and other kinds of flu by using public databases. In digital biology activity 1, we learned about the kinds of creatures that can get flu. Personally, I’m a little skeptical about the blowfly, but… Now, you might wonder,…

Genome sequences from California and Texas isolates of the H1N1 swine flu are already available for exploration at the NCBI. Let’s do a bit of digital biology and see what we can learn. Activity 1. What kinds of animals get the flu?

A couple of years ago, I answered a reader’s question about the cost of genome sequencing. One of my readers had asked why the cost of sequencing a human genome was so high. At that time, I used some of the prices advertised by core labs on the web and the reported coverage to estimate…

In which we search for Elvis, using blastp, and find out how old we would have to be to see Elvis in a Las Vegas club.

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 and how it works and…

What do the missing Romanov children, genetically engineered humans, financial risk taking, and poop have in common? You can read about all these topics from this month’s Gene Genie carnival at Mary Meets Dolly. Who would have thought that mutations could be so much fun?

A long-sought goal in genetics has been to develop therapies that can use correctly functioning genes to replace genes with defects. If we had the technology to predictably modify our genomes, we would have the ability to cure many diseases instead of having to place people on medications for their entire lives. For a long…

My garden at home is looking a bit bleak after all the snow, Mendel’s Garden is blooming wonderfully at Jeremy Cherfas’ blog Another Blasted Weblog. Jeremy has prepared a nice collection of perennial favorites. I especially like the story about pea breeding and, if you view the post, there are several interesting pictures of peas.…

The New York Times had a great article a couple of days ago on the need for personalized medicine to become more than a catchy phrase. As we’re learning more about the interaction between genes and drug metabolism, we’re also learning that large numbers of people are either taking the wrong drug or taking drugs…

Mosquito-borne diseases, like Dengue and Malaria, are serious problems in many parts of the world. While some people are working on treatments for mosquito-carried disease, others are looking at ways to treat the mosquitoes. Figure 1.
