Income, education, and policy priorities

Political Science Research and Methods
Are people's priorities associated with their income and education levels? There is a long history in political science of claims that priorities are driven by economic interests, but also that low-income and low-education people fail to prioritize their

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Competent legislators or mere pawns? Experimental evidence of attitudes toward gender quota politicians

Political Science Research and Methods
Do citizens evaluate quota and non-quota politicians similarly? Do voters perceive quota-elected politicians as less competent and autonomous? Despite the proliferation of gender quotas, it remains unclear how citizens view female quota politicians ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
