Abstract
A modification of the two-dimensional protein electrophoresis system of O'Farrell was used to resolve influenza A virus proteins from each other and from host proteins in infected cells. Viral protein spots corresponding to the hemagglutinin proteins, neuraminidase, nucleocapsid protein, and nonstructural protein, were identified on the two-dimensional electrophoretogram. Use of the two-dimensional separation has allowed us to identify glycoprotein heterogeneity, to demonstrate directly the synthesis of neuraminidase, to analyze some viral proteins early after infection, and to demonstrate that the influenza virus NP and NS proteins are phosphorylated in infected MDCK cells.

A study exploring intergenerational social mobility in the United States finds that fewer people born in the 1980s were upwardly mobile than those born in the 1940s and that the slowing of status mobility accentuates inequalities of opportunity.

A study suggests that social learning from exposure to opposing political views on social networks can improve accuracy and remove partisan bias, but displaying political symbols during cross-party communication can prevent such learning, according to the authors.
