X-ray diffraction microscopy peers into tiny cells（图）
X-ray diffraction microscopy tiny cells
2009/11/24
Two independent groups of physicists have found a new way to get high-definition glimpses of the innards of living cells. The technique uses X-ray diffraction microscopy on cells frozen below –170 °C,...
01 May 2007，Manta rays are hard to miss —big, black and stretching up to seven metres wide, but scientists are still in the dark about the world’s largest ray.

26 January 2007，Lenses for x-rays are notoriously tricky to manufacture because they rely on nanometre-scale features. For this reason, physicists developing x-ray microscopes have been keen to adopt ...
16 November 2006，Many biological cells are too small to be studied with an optical microscope and higher-resolution techniques such as x-ray diffraction and electron microscopy cannot be readily adapt...
