Making Babies; the New “Normal”

Once upon a time in a fairy tale land that now seems far, far away, young people fell in love, got married, and started a family. But the idea of “starting a family” has taken on new meaning as pregnancy has come under the rubric of technological control. Increasingly, it is not about having children but about “making babies.” With the advent of technology and... // Read More »

Germline Alteration and Defining “Just Research”

Yesterday’s post by Steve Phillips raises a central question for us in the “biotech century”:  are there some sorts of experiments that fundamentally ought not be done because of the potential they will be grossly misapplied by bad actors?  Steve cited research by Lord Robert Winston seeking to create genetically altered pigs—that seem, from the description in the press, to be what scientists call “transgenic”... // Read More »

New method for genetic modification – genetic alteration of sperm

Germline genetic modification is a technique that some find intriguing and many find very concerning when its use is considered in humans. However there are uses of germline genetic modifications in animals that may impact humans in multiple ways. In an article in The Telegraph, British researcher Robert Winston talks about current research to develop animal organs (usually from pigs) that could be genetically modified... // Read More »

“Faking” Life?

Synthetic biology—loosely defined as the intersection of engineering and biology—is a burgeoning field with the potential to create or alter “non-naturally” occurring organisms using basic biomolecules, or similar molecules not found in living things as we encounter them.  A few years ago, Dr. Craig Venter’s group in San Diego synthesized the entire DNA of one species of mycobacterium on a lab bench, added some identifier... // Read More »

Last Week’s Stem Cell Cloning News

Readers of this blog probably saw last week’s report, as the NPR headline put it, that “First Embryonic Stem Cells Cloned from a Man’s Skin.”  I was able to read the full text of the online publication, by Cell Stem Cell, here. The stated goal of the work is to use somatic cell nuclear transfer (SCNT) to clone an embryo that can then be used... // Read More »

Reflections on the Metaphors We Live–and Die–By

Images powerfully impact how we think and how we live. Metaphors, those images we use to describe the indescribable, to portray the unfamiliar and mysterious, are particularly so because of the identity relationships they create. In my last post, I commented on an article in the NYT entitled, “A Tumor: the Embryo’s Evil Twin,” which described the similarities between embryogenesis and the cellular behavior of... // Read More »

Happiness study draws frowns from critics

A high-profile 2013 study that concluded that different kinds of happiness are associated with dramatically different patterns of gene activity is fatally flawed, according to an analysis published on Monday which tore into its target with language rarely seen in science journals.

Why are some depressed, others resilient? Scientists home in one part of the brain.

Many of us find ourselves swimming along in the tranquil sea of life when suddenly a crisis hits — a death in the family, the loss of a job, a bad breakup. Some power through and find calm waters again, while others drown in depression.
