How long will it be before prenatal care involves sequencing the genome of a fetus to detect genetic disorders before birth? Several recent reports have shown it can be done, based on the tiny bits of DNA that float around in the mother-to-be's blood plasma during pregnancy. Another such study came out this week in the journal Nature -- with some important advances. In the past, fetal-genome analyses have involved getting samples of DNA from three places: the woman's blood cells (to identify her genome)

POCATELLO, Idaho - When Pocatello police got a tip that Jennie Linn McCormack had ended her pregnancy by taking an abortion drug obtained over the Internet, they showed up at her apartment one cold January day in 2011 and demanded an explanation. McCormack eventually took them out to her back porch, where the remains of her fetus were on the barbecue, wrapped up in a plastic bag and a cardboard box. "My baby is in the box," McCormack said. Officers uncovered the frozen remains of a 5-month-old fetus and erected crime scene tape around the porch before taking her to the police station and charging her with a felony.

Scientists have pieced together the entire DNA sequence of an 18-week-old fetus without having to use any invasive tests that could result in a miscarriage - an advance that offers a glimpse of the future of prenatal testing. Using blood drawn from the mother and a sample of saliva from the father, the researchers were able to scan the fetus' genome and determine whether it contained any of the myriad single-letter changes in the DNA code that can cause a genetic disorder. They could even pinpoint which mutations were inherited from Mom, which came from Dad, and which were brand-new.

A San Bernardino County man accused in the beating death of his pregnant girlfriend was arrested after a post appeared on his Facebook page implying that her death was an accident. Willie Davis Hines Jr., 23, was booked into the San Bernardino County Central Detention Center on two counts of murder in connection with the death of Tatjana Cruz, 24, and the fetus she was carrying, the San Bernardino County Sheriff's Department said Tuesday. He was being held without bail. Hines allegedly beat Cruz after a dispute, authorities said.

Plesiosaurs — giant marine reptiles that ruled the oceans 75 million years ago — gave birth to single large babies and may even have nurtured their young, according to a new study. F. Robin O'Keefe, a paleontologist at Marshall University in Huntington, W.Va., and Luis Chiappe, director of the Dinosaur Institute at the Natural History Museum in Los Angeles, teamed up to study the only known fossil of a plesiosaur mother and her unborn baby. The ancient relic is considered the first evidence that these aquatic behemoths gave birth in the water instead of laying eggs on land, the researchers reported online Thursday in the journal Science.

Women may soon be able to find out very early in their pregnancies whether they are carrying a fetus with Down syndrome by offering a simple blood sample. The safe, noninvasive test would pose fewer risks to the mother and fetus than amniocentesis or chorionic villus sampling (CVS), the two tests currently used for prenatal diagnosis. It would also give women more time to decide what to do if a diagnosis of Down syndrome is made. Researchers from the Chinese University of Hong Kong have been working on the DNA-based test for a decade.
