...atoms may seem minuscule--especially if they exist for only fractions of a second--but they can have huge implications. The recent announcement that Russian and American scientists finally managed to produce a tiny bit of element 117 by firing calcium atoms (element 20) at berkelium (element 97) fills in a missing spot on the periodic table. When the results are confirmed, "ununseptium" will get a catchier moniker and occupy the square between 116 and 118--elements that also await proper names from the International Union of Pure and Applied Chemistry...
With repeated exposure at high enough levels, lead can cause cognitive damage and behavioral changes in children. In most cases, lead poisoning can be treated by reducing the child's exposure and by making sure he or she eats a balanced diet with sufficient iron, calcium and vitamin C - deficiencies in these can increase the body's absorption of lead. In extreme cases of extended lead exposure, doctors use drugs called chelating agents, which bind to the lead and pull it out of the body through urine. In severe cases of prolonged poisoning, however, the cognitive and developmental damage...
...when Rutzel first sought help for anemia and osteopenia, a precursor of osteoporosis triggered by her avoidance of calcium, her doctor in upstate New York, where she attended college, had never heard of orthorexia. "You should be trying to eat healthy," she remembers him telling her.

Her condition was eventually identified as anorexia, a diagnosis that organizations like the Washington-based Eating Disorders Coalition think is a mistake. The group, which represents more...
With a $53,000 grant from NSF, the pair embarked on their first independent research project in Sept. 2009. Using Harvard’s million-dollar mass spectrometer, they are studying calcium isotopes in rocks in order to better understand geological history...
