Scientists like to use x-rays when determining chemical structures to develop drugs, but it's an agonizingly slow process. As they need large, pure crystals, it can take weeks or even years to produce something big enough for studying. However, that time might be cut down to a matter of minutes. Researchers have developed a CT scan-like technique that can quickly and easily detect the shape of very small organic molecules. It borrows elements of the x-ray technique, but doesn't demand the large crystals.
