Killer's DNA Won't Explain His Crime

A person's DNA can say a lot about a person, but not why someone has committed a horrific crime like mass murder.

Connecticut's chief medical examiner, Wayne Carver, has raised the possibility of requesting genetic tests on Adam Lanza, the man responsible for the shootings at Sandy Hook Elementary School.

Carver hasn't said precisely what he may want geneticists to look for, but scientists who study the links between genes and violence say those tests won't reveal much about why Lanza did what he did.

Genome Sequencing For Babies Brings Knowledge And Conflicts

Originally published on Tue December 4, 2012 9:21 am

By sequencing a newborn's genome, doctors could screen for more genetic conditions. But parents could be confronted with confusing or ambiguous data about their baby's health.

When Christine Rowan gave birth prematurely in August, her new baby was having problems breathing. So Rowan brought her daughter, Zoe, to the Children's National Medical Center in Washington, D.C., for genetic testing.

"It's funny because when we first had the testing done, we didn't even really think about the fact the testing was going to lay out all of her DNA," says Rowan, 32, who lives in Northern Virginia.

But while Rowan and her husband were waiting for the results, questions started popping into their heads.

A massive research project in California is beginning to show how genes, health habits and the environment can interact to cause diseases. And it's all possible because 100,000 people agreed to contribute some saliva in the name of science.

Could bacon get any tastier?

Pig scientists and breeders say indeed it could, now that the pig genome has been sequenced and a trove of new genetic information is available.

The Swine Genome Sequencing Consortium, an international group of researchers, published their analysis of the genome this week in Nature.

Geneticist reported Wednesday that they had crossed a threshold long considered off-limits: They have made changes in human DNA that can be passed down from one generation to the next.

The researchers at Oregon Health & Science University in Portland say they took the step to try to prevent women from giving birth to babies with genetic diseases. But the research is raising a host of ethical, social and moral questions.
