A major international research group rang alarm bells Monday over the scourge of hidden hunger, also known as vitamin and mineral deficiencies, which affects over two billion people with often devastating consequences.

A Texas health care worker has become the first person to contract Ebola on American soil, authorities confirmed Sunday, blaming a safety breach for the spread of the deadly disease.
