“Are you still collecting stories about DTC testing? I've got one for you!” my grad student L.W. e-mailed a few days ago. Little did I know her family's experience would change my mind about direct-to-consumer genetic testing.

L.W. had taken my online course “Genethics” in 2008 for the master’s program at the Alden March Bioethics Institute of Albany Medical College. Read More

Gene Therapy Changes the Brain

It doesn't take a brain scientist to see that the visual cortex of this formerly-blind woman lights up -- after gene therapy.
It isn’t often that a brain scan chokes me up, but this one did. The fMRI shows area 17 of the visual cortex coming to life in a woman born with Leber congenital amaurosis type 2 (LCA2). She’s part of the very same gene therapy clinical trial chronicled in my upcoming book The Forever Fix: Gene Therapy and the Boy Who Saved It. The symbolic boy is Corey Haas, who, four days after gene therapy in 2008 at age 8, screamed when he saw the sun at the Philadelphia zoo, his shadow world suddenly brightened. Read More

The Crime Gene Revisited

"Research shows genes influence criminal behavior," proclaims a January 25 news release, setting my genetic determinism detector on high alert.

I flashed back to the cover of the May 18, 1970 Newsweek, “Congenital Criminals?” which probed the work of Patricia Jacobs. Here’s what my human genetics textbook says on the study provoking the 1970 headline:  Read More

A Textbook Author’s View of “5-Minute Publishing”

It takes a village to produce a textbook.
iBooks Author “will let anyone make their own interactive textbook, in like 5 minutes flat,” according to several reports on Apple’s January 19 announcement. Then why did my first college textbook, Life, take 10 years?

It’s simple: researching, writing, editing, and publishing  Read More

Ricki’s Rant: Genome Sequence, NOT Genetic Code

Strawberries can use a gene from peanuts to withstand frost because the genetic code is universal.
Humans do not have their own genetic code, and certainly each of us does not have his or her own. The idea of our utter uniqueness might be attractive, but genetics just doesn’t work that way. And it’s a good thing.

The genetic code is the correspondence between a unit of DNA  Read More

We are all people of color, except the Invisible Man and Woman.
I struggle to stay politically correct when updating my human genetics textbook. “Hemophiliac” became “person with hemophilia” and “victim” vanished several editions ago. In the current incarnation, “mentally retarded” became “intellectually disabled” after colleagues warned that  Read More

Gene Therapy and the 10,000-Hour Rule

“Breakthroughs” in biomedicine are rarely that – they typically rest on a decade or more of experiments. Consider gene therapy.

I just unearthed an article from the December 1990 issue of Biology Digest, "Gene Therapy." I wrote it a mere two months after the very first gene therapy experiment, the much-publicized case of 4-year-old Ashi DeSilva,  Read More

I don’t usually take too kindly to the evil geneticist stereotype in fiction, but I can’t resist a good dystopian novel. "When She Woke," by Hillary Jordan, is the perfect book  Read More

A Living Blood Vessel "Stamp"

December 16, 2011
Tags: blood vessel, tissue engineering, University of Illinois at Urbana-Champaign, Hyunjoon Kong, Ricki Lewis
I still marvel at the interface between a tissue and an organ, even after a quarter century of writing college biology textbooks.

I can easily envision a sheet of epithelium folding itself up into the tiny tube of a capillary. But how do only four basic tissue types connect and contort to fashion such  Read More
