Semi-circular rows of computers, electronic switchboards and unobtrusive decor make the Operations Control Center (OCC) for NASA's Advanced X-ray Astrophysics Facility (AXAF) look like a scaled-down version of the mission control rooms in movies...
...miracle drugs. No wonder cures. No promises of panacea. The AIDS breakthrough announced Thursday in the journal Nature is a far more critical step: The decoding, if you will, of HIV's encryption key. For the first time, scientists have been able to snap X-ray pictures of what exactly happens when the virus that causes AIDS latches on to our immune cells -- and it's proving itself to be a more pernicious predator than anyone imagined. Dozens of spikes of protein stick out of its side, swathed in sugar so our antibodies won't be able to tell...
While his work focused primarily on SPECT, some of Holman's most ground-breaking research came in 1987 when he used X-ray and CAT-scan imaging to analyze the bodies of several Egyptian mummies...
...techniques of choice for this sort of cartography are x-ray crystallography and protein nuclear magnetic resonance spectroscopy (NMR), which take a snapshot of a protein at a resolution of less than a billionth of a meter...
...X-ray crystallography allows us to map out the atom-by-atom three-dimensional structure of a drug target, [especially] the active site," says Brum. "The more precise information we can have about the active site helps us to develop a safer, more potent drug...
