Masha Gessen was faced with a terrifying choice: cut off her breasts, and possibly save herself from cancer, or use them to feed her child.

Why should professional scientists have all the fun? Researchers have been engineering glowing cats, and selling glowing fish at pet stores. High school kids can do genetic engineering too, if they have the right equipment. And you can help them get the equipment by contributing to our DonorsChoose fund drive. If you’re willing to help…

Maybe you did it for the extra cash. Maybe you wanted to be part of the sperm cube public art project. Whatever the reason, it’s possible, just possible, your sperm took on a life of it’s own, once you left it. And now that a genome is no longer an entirely personal bit of information,…

One of the holy grails of modern medicine is the development of a vaccine against HIV, the virus that causes AIDs. An obstacle to attaining this goal has been the difficulty in stimulating the immune system to make it produce the right kinds of antibodies. A recent finding in Science describes a gene that controls…

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 here) have been arguing about whether or…

One of the things that drives me crazy on occasion is nomenclature. Well, maybe not just nomenclature, it’s really the continual changes in the nomenclature, and the time it takes for those changes to ripple through various databases and get reconciled with other kinds of information. And the realization that sometimes this reconciliation may never…

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 over 100 different breeds and they’ll…

This the third part of case study where we see what happens when high school students clone and sequence genomic plant DNA. In this last part, we use the results from an automated comparison program to determine if the students cloned any genes at all and, if so, which genes were cloned. (You can also…

This the second part of three part case study where we see what happens when high school students clone and sequence genomic plant DNA. In this part, we do a bit of forensics to see how well their sequencing worked and to see if we can anything that could help them improve their results the…

What happens when high school students clone and sequence genomic DNA? Background DNA sequencing is a wonderful tool for discovery and a great technique for getting students involved in molecular science. This fall, Bio-Rad will officially begin selling their DNA cloning and sequencing kit. Now, students across the country will have the tools in hand…
