Columbia-led study of more than 38,000 women enables faster, first trimester prenatal testing for leading cause of mental retardation and birth defects
A new study from Columbia University Medical Center researchers at NewYork-Presbyterian Hospital/Columbia of more than 38,000 pregnant women at 15 U.S. centers demonstrates the high accuracy of non-invasive screening for Down syndrome (also known as trisomy 21) in the first trimester of pregnancy, at 11 weeks. The findings are a significant advantage over the current standard screening, a blood test performed in the second trimester of pregnancy.
"These results will undoubtedly change national practice – all pregnant women should have the option of early screening for Down syndrome in their first trimester," said Mary E. D’Alton, M.D., principal investigator of the study. She is Chair of the Department of Obstetrics and Gynecology at Columbia University College of Physicians and Surgeons, and Chief of Obstetrics and Gynecology at NewYork-Presbyterian Hospital/Columbia. "Down syndrome screenings based on either maternal age alone, or an ultrasound or sonogram alone, are no longer justified protocols."

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
