This Week in Nature: May 10, 2007

A news feature writes about the complexities associated with advanced fluorescence microscopes when it comes to live cell imaging. Considering how fast the field of cellular imaging is advancing, the piece warns cell biologists to think twice about whether the images they capture are accurate shots of that "bustling traffic of the cytoplasm."

Welcome to the fold, Monodelphis domestica! Today's cover paper reports on the sequencing of the grey, short-tailed opossum by Eric Lander's lab at the Broad. Being the first marsupial species to be sequenced, the furry grey one will provide insight into mammalian genome organization and evolution.

At the Picower Institute for Learning and Memory at MIT, researchers found that chromatin modifications, specifically increased histone-tail acetylation, helped mice models regain access to long-term memory if they had experienced loss of neurons and brain atrophy. Their work has implications for the study of neurodegenerative diseases.
