<jats:p>Right next door and easy to study, Andromeda provides an excellent model of how our own galaxy probably evolved.</jats:p>

<jats:p>A project to “crowdsource” galactic classifications has paid off in ways the astronomers who started it never expected.</jats:p>

<jats:p>Individual low-mass stars have very long lives, comparable to the age of the universe, and can thus be used to probe ancient star formation. At present, such stars can be identified and studied only in the Milky Way and in the very closest of our neighboring galaxies, which are predominantly small dwarf galaxies. These nearby ancient stars are a fossil record that can provide detailed information about the physical processes that dominated the epoch of galaxy formation and subsequent evolution.</jats:p>

<jats:p>Major advances in observational astronomy over the past 20 years have revolutionized our view of cosmic history, transforming our understanding of how the hot, smooth, early universe evolved into the complex and beautiful universe of stars and galaxies in which we now live. I describe how astronomers have used a range of complementary techniques to map out the rise and fall of star formation over 95% of cosmic time, back to the current observational frontier only ~500 million years after the Big Bang.</jats:p>

<jats:p>One of the most fascinating discoveries in the past decade was that galaxies typically contain a centrally located black hole with a mass that is millions or even billions of times that of the Sun. There is now compelling evidence that we cannot understand how galaxies formed and evolved without understanding the life cycles of these supermassive black holes (and vice versa). We summarize the current understanding of this coevolution of galaxies and supermassive black holes (based largely on observations of the local, present-day universe) and describe prospects for the future.</jats:p>

<jats:p>An epigenetic program regulated by MeCP2 needs to be maintained throughout life for normal neurological function.</jats:p>

<jats:p>Gylcolytic oscillations in yeast are a by-product of a trade-off between robustness and efficiency.</jats:p>

<jats:p>The lifetimes of injected jet puffs are used to determine the critical point at which turbulent pipe flow is sustained.</jats:p>

<jats:p>Measurement of an extremely weak spectroscopic transition in helium hones fundamental atomic theories.</jats:p>

<jats:p>A recent bright emission observed by the Swift satellite is due to the sudden accretion of a star onto a massive black hole.</jats:p>
