No Easy Way Through: Black Workers and Race Leadership at the Nadir

It is difficult, even excruciating, to imagine the staggering descent from high optimism to despondency experienced by many African Americans who lived between emancipation and the dawn of the twentieth century. For historians living in the post–civil rights era, recapturing the scale, velocity, and brutality of that dramatic fall has been hampered by two conceptual problems. The first of these, undergirded by prominent trends in the formerly “new” social history, is a widely shared enthusiasm for illuminating those hidden corners of daily life where men and women on the receiving end of Jim Crow continued to wield a degree of control. “Agency” has been the buzzword for a generation of scholarship that emphasizes the staying power and persistence of black Southerners in the face of relentless assaults on their social and economic status, their civil rights, and even, at times, their collective existence. This is, in many ways, an understandable reaction to an earlier consensus that relegated black historical initiative to the margins of a national fable cleansed of unseemly violence and sharp social conflict, but it can also be problematic.

'Last Vegas?'

This article, and the research out of which it springs, has a number of points of origin; it may also have more than one point of conclusion even as it argues that the current manifestation of Las Vegas could well be read as its last. This is not to say that Las Vegas will cease to create its new versions of itself; after all, this is one of the main sustaining factors of Las Vegas’ success in the last two decades as a new Strip on Las Vegas Boulevard has arisen from the demolitions and redesigns of the original Las Vegas Strip of the 1950s and 1960s. What is argued for here is a reading of Vegas as a terminal point within American culture and particularly within its visual realms. Las Vegas’ place within the dynamics of American visual and exhibition culture comes as the latest in a sequence which, since the nineteenth century, has included among its manifestations World’s Fairs, side shows, freak shows and travelling carnivals. America’s experiments in the visual domain have been updated in both the twentieth- and twenty-first centuries in a variety of spectacular forms and entertainment zones (Disneyland, EPCOT, the new Las Vegas). Vegas is the ultimate incarnation of a carnivalised display culture, the city’s casino Strip reclothed primarily as a theme park for digital camera-toting tourists than as a resort for dedicated gamblers. The possibility that the current incarnation of Las Vegas of late 2009 and 2010 will be the last Vegas hovers as a spectral remnant of the economic downturn and financial collapse of 2008, marked by the unfinished skeletons of projected new casino hotels on Las Vegas Boulevard and by a sudden reversal of fortune for the nation’s favourite gaming location.

Ancient DNA reveals late survival of mammoth and horse in interior Alaska

Causes of late Quaternary extinctions of large mammals (" megafauna") continue to be debated, especially for continental losses, because spatial and temporal patterns of extinction are poorly known. Accurate latest appearance dates (LADs) for such taxa are critical for interpreting the process of extinction. The extinction of woolly mammoth and horse in northwestern North America is currently placed at 15,000-13,000 calendar years before present (yr BP), based on LADs from dating surveys of macrofossils (bones and teeth). Advantages of using macrofossils to estimate when a species became extinct are offset, however, by the improbability of finding and dating the remains of the last-surviving members of populations that were restricted in numbers or con-fined to refugia. Here we report an alternative approach to detect 'ghost ranges' of dwindling populations, based on recovery of ancient DNA from perennially frozen and securely dated sediments (sedaDNA). In such contexts, sedaDNA can reveal the molecular presence of species that appear absent in the macrofossil record. We show that woolly mammoth and horse persisted in interior Alaska until at least 10,500 yr BP, several thousands of years later than indicated from macrofossil surveys. These results contradict claims that Holocene survival of mammoths in Beringia was restricted to ecologically isolated high-latitude islands. More importantly, our finding that mammoth and horse overlapped with humans for several millennia in the region where people initially entered the Americas challenges theories that megafaunal extinction occurred within centuries of human arrival or were due to an extraterrestrial impact in the late Pleistocene.
