Unearthing the Weeping Time: Savannah's Ten Broeck Race Course and 1859 Slave Sale

[From race to health in Master and slave].

The article analyzes how Gilberto Freyre addresses health-related issues in his book Master and slave. the first point of focus is how the sanitation movement that emerged in the sertão region in the late 1910s influenced Freyre's essay. The article next endeavors to understand the relation between Freyre's emphasis on the problem of syphilis in Brazil and the issues of race and miscegenation, ...

Multiple Cues in Social Perception: The Time Course of Processing Race and Facial Expression.

The purpose of the present study was to examine the time course of race and expression processing to determine how these cues influence early perceptual as well as explicit categorization judgments. Despite their importance in social perception, little research has examined how social category information and emotional expression are processed over time. Moreover, although models of face proces...

Event-related potentials and time course of the "other-race" face classification advantage.

Other-race faces are less accurately recognized than same race faces but classified faster by race. Using event-related potentials (ERPs), we captured the brain temporal dynamics of face classification by race processing performed by 12 Caucasian participants. As expected, participants were faster to classify by race Asian than Caucasian faces. ERPs results identified the occurrence of the othe...

Unearthing modified RNAs

in cells. To explore this landscape further, Kowtoniuk et al. have developed chemical profiling methods to identify RNA–small molecule conjugates occurring in cells. The two different approaches used both apply chemical cleavage conditions to a fraction of total cellular RNA from the bacteria Escherichia coli and Streptomyces venezuelae. The resulting small-molecule fractions were then analyzed...
