Illuminating the darkest galaxies

چکیده

Low luminosity dwarf galaxies provide stringent constraints on the nature of dark matter. Establishing these depends precise kinematic measurements individual stars. In this overview for non-specialists, we describe current and future prospects three unique tests matter using resolved stellar kinematics in low galaxies: overall number satellite around Milky Way, dark-matter annihilation radiation from galaxies, their internal density profiles. We then assess meaningfully testing theories based improved precision expected upcoming facilities.

Illuminating the Dark Proteome

A large segment of the proteome consists of disordered regions, yet in most cases, little is known about their mechanisms and functions. What are the roles of protein disorder in cell biology, and how do intrinsically disordered proteins function? These are the questions Cell's Robert Kruger posed to Madan Babu, Julie Forman-Kay, and Richard Kriwacki. Annotated excerpts from this conversation a...

Illuminating the secretory pathway

Proteins destined for secretion, the plasma membrane or membranous cellular organelles enter the secretory pathway in the endoplasmic reticulum (ER) and move via the Golgi complex to the trans-Golgi network, where they are sorted and transported to their final destination. Malfunction in this pathway may lead to the breakdown of cellular organelles, cell polarity, overall cellular architecture ...
