Getting fetusí genetic makeup from mother blood test

The days of pregnant women having a 3-inch-long (8-centimetre-long) hollow needle jabbed into their abdomens may be numbered.

For the second time in a month, scientists have announced that a simple blood test, rather than more invasive tests such as amniocentesis, can determine a fetusís genetic make-up, identifying mutations causing any of about 3,000 inherited disorders that arise from a glitch in a single gene, such as cystic fibrosis.

Unlike a procedure unveiled last month, the one announced Wednesday in the journal Nature can be done without knowing who the father is, much less obtaining a sample of his DNA. Since paternity is unknown or incorrect in an estimated 3 to 10% of births in the United States, the father-free method promises to make fetal DNA sequencing possible in every pregnancy, if hurdles including cost and accuracy are overcome.

"Weíre really on the verge of an enormous increase in our ability to understand what an infant will be like," said Dr Michael Katz, a senior adviser to the March of Dimes, a foundation that supports research on pregnancy and birth defects. Katz was not involved in the study. "Youíll be able to detect any kind of abnormality early, quickly, without distress and safely. This is the way of the future."

Determining a fetusís genome might give women more reasons to end a pregnancy. But it would also let physicians identify conditions that can be treated before birth or immediately after, said Stephen Quake of Stanford University in California, who led the new study: "The way itís done now, parents wait until a newborn gets sick and suffers in the first weeks of life, and only then does the doctor start figuring out the baby has a metabolic or immune disorder."

With prenatal genetic testing, in contrast, the parents would know by the end of the first trimester (12 to 13 weeks) if the fetus has a genetic or chromosomal defect. That way, they can be ready if the baby has special needs, which can be as simple as a certain diet.

Into Eternity is a documentary about a deep geological repository for nuclear waste. The concept of long-term underground storage for radioactive waste has been explored since the 1950s. The inner part of the Russian doll-like storage canisters is to be composed of copper. Hence in the case of Onkalo it is tightly linked to experiments on copper corrosion in running ...
