The kilogram gets a makeover

In Sèvres, a small commune on the outskirts of Paris, lies a gleaming lump of metal the size of a palm. Le Grand K, or Big K as they call the platinum and iridium alloy, sits underground in a high-security vault. It is held ...

How disposable diapers can improve measurements of tumor growth

Catching cancer early can make all the difference for successful treatment. A common screening practice measures tumor growth with X-ray computed tomography (CT), which takes a series of cross-section images of the body.
