Maria and Teresa Tapia Maria and Teresa Tapia Maria and Teresa Tapia (born April 8, 2010) are formerly conjoined twins born in the Dominican Republic. The twins were joined by their lower chest and abdomen and were therefore classified as omphalopagus sharing a liver, pancreas, and a small portion of their small intestine. On November 7, 2011, the twins underwent a successful separation surgery at the Children's Hospital of Richmond in Virginia. For every 200,000 live births, conjoined twins are born.

TWINS TWINS Two Wide-Angle Imaging Neutral-Atom Spectrometers (TWINS) are a pair of NASA instruments aboard two United States National Reconnaissance Office satellites in Molniya orbits. TWINS was designed to provide stereo images of the Earth's ring current. The first instrument, TWINS-1, was launched aboard USA-184 on 28 June 2006. TWINS-2 followed aboard USA-200 on March 13, 2008. Each instrument consists of an energetic neutral atom imager and a Lyman alpha detector. The ENA imager provides indirect remote sensing of the ring current ions, and the Lyman alpha detector gives a measure of the neutral hydrogen cloud about the Earth, known as
