Getting a Transcription Factor to Only One Nucleus Following Mitosis
The Ace2 transcription factor from budding yeast has both a regulated nuclear localization signal and a regulated nuclear export signal, and Ace2 phosphorylation by the Cbk1 kinase results in Ace2 accumulation in daughter cells but not mothers.

How Signaling Receptors Meet Their End
A new study sheds light on the roles of two proteins involved in vesicle trafficking within the cell and shows that intralumenal vesicle formation in multivesicular body biogenesis can be uncoupled from lysosomal targeting.

An Enzymatic Palimpsest
How does nature construct complex catalysts? Molecular simulations revealed two sets of catalytic residues in the enzyme IMPDH, one of which seems to represent a primitive catalytic machinery that may be a vestige of evolution.

A New Role for a Long-Studied DNA-Wrangling Enzyme
Analysis of cells lacking topoisomerase II reveals that the enzyme has an essential role in the segregation of chromosomes, and specifically centromeres, at anaphase-telophase of mitosis: it prevents non-disjunction and allows activation of the Aurora B kinase, so as to correct improper attachments between microtubules and the kinetochore.

Defining a Link between Perceptual Learning and Attention
Takeo Watanabe and Yuko Yotsumoto explore the implications of a new study that shows that for perceptual learning of visual features involving multiple stimuli to occur, the brain needs to temporally "tag" the features, a learning process that requires paying attention.

Where Does Bluetongue Virus Sleep in the Winter?
Bluetongue recently spread to northern Europe for the first time. Outbreaks in temperate regions are often interrupted by cold weather, but may reappear months later. Where, then, might bluetongue virus sleep in the winter?

August 2008 Issue
PLoS Biology is a peer-reviewed open-access journal featuring research articles of exceptional significance in all areas of biological science, from molecules to ecosystems.
From the Web
The Naked Scientists are a media-savvy group of physicians and researchers from Cambridge University who use radio, live lectures, and the Internet to strip science down to its bare essentials and promote it to the general public. Their award-winning, weekly BBC radio program has an international following.
