The enzyme structure is the first ever solved of a member of a family of enzymes that remove sugars from lipids and attach them to other sugars. This process is used in a wide rang...

Imaging techniques permit scientists to follow a day -- or four -- in the life of a cell

...otocols.org/cgi/content/full/2007/1/pdb.prot4657 , details a procedure to inject proteins into individual cells. The injected protein can be fluorescently labeled, so scientists can track the glowing protein with a microscope and observe what it's doing and where it's going inside the cell. This microinjecti...

Imaging pinpoints brain regions that 'see the future'

...riment, participants were not required to describe details or explain the origin of mental images elicited by the memory cues, but in post-testing questionnaires most indicated that they tended to place future-oriented images in the context of familiar places (e.g. home, school) and familiar people (e.g. fam...
