Drive by Science is OK Too

Drive by Science is OK Too

The author feeling cheekyLast Monday I finally took my show out on the road. At The Tech Museum I run hands on genetics programs for visitors. On Monday, we took them to Overfelt High School in San Jose. And the students had a blast*. They got to take home 4X6 glossy pictures of their cheek [...]

 
Chromosome Fusion: Chance or Design?

Chromosome Fusion: Chance or Design?

Human and chimpanzee chromosomes are very similar. Note that human chromosome 2 is very similar to a fusion of two chimpanzee chromosomes. For the last few weeks I have been corresponding with someone about intelligent design (ID). More specifically, we have been chatting about why humans have 46 chromosomes and most of the great apes [...]

 
Fish and SNPs: What fish are teaching us about human skin color

Fish and SNPs: What fish are teaching us about human skin color

These fish can tell us a lot about ourselves. Species often end up a different color when their environment changes. And humans are no exception. When people moved out of Africa tens of thousands of years ago, they were dark-skinned. Now when we look around Northern Europe or parts of Asia, we see much lighter [...]

 
Hug-a-helix: celebrate DNA Day, April 25th

Hug-a-helix: celebrate DNA Day, April 25th

DNA magnified 850,000 times through a scanning electron microscope DNA day is coming up on Friday April 25th. This annual celebration of genetics and genomics was set up in 2003 to commemorate the sequencing of the human genome and the 50th anniversary of the solving of the structure of DNA.DNA day was thought of as [...]

 
Producer's Notes - Doggie DNA

Producer's Notes - Doggie DNA

There is a lot we don't know about our DNA and how it works. While there seems to be news every week about genetics, scientists are still in the early stages of finding out what effect our genes have on us (check out this post from another QUEST blogger, Dr. Barry Starr). That's what the [...]

 
DNA and Love

DNA and Love

Last night, I watched a reality dating show with a seemingly wacky way of finding true love. The male searching for love sniffed the armpits of potential females. He either turned away in disgust or became quite aroused by the wafts of underarm aroma. What is so comical is that a new dating service relies [...]

 
Tracing the Travels of the Human Race

Tracing the Travels of the Human Race

We are all Africans in our DNA. We all originally came from Africa. At least that is what a couple of new studies have claimed. Now this isn't breaking news. Other studies have looked at people's DNA and proposed the "Out of Africa" hypothesis. What is different with these studies is how many people they [...]

 
Using life as a tool

Using life as a tool

Companies like GenoCAD allow users to piece together their own designer DNA. “Synthetic biology” seems like a contradiction in terms, doesn’t it? I mean, if it’s biological, it’s natural, right? And if it’s natural, then it’s not synthetic. Sure. Except that modern science has sorta blurred all those nice convenient boundaries. Nothing has demonstrated this [...]

 
How to get away with murder

How to get away with murder

ABC, Yahoo! and others ran a story about a woman who had a liver transplant whose blood type ended up changing. I love stories like this. Not because of the change itself. Most likely, stem cells traveled from the new liver to the patient’s bone marrow. There, the stem cells set up shop and gave [...]
