Researchers in New Mexico are reporting the surprise discovery that common table salt - so brittle that it crushes easily between a thumb and forefinger - becomes a super plastic in the weird environs of the nanoworld. The super-elastic salt can stretch like taffy to twice its original length without breaking. The discovery could lead to new insights into the role of salt in a wide variety of situations ranging from helping clouds to form to triggering asthmatic attacks in people, they say. Their study is in the current issue of ACS' Nano Letters, a monthly journal...
