depression

Researchers report the discovery of a molecular switch activated by stress that appears to drive depression, offering a possible biological explanation for how chronic stress leads to depressive symptoms. The finding could point toward new drug targets and treatments that work on the underlying mechanism rather than symptoms alone. Details of the study, including the researchers involved and where it was published, were not immediately available.

Election forecasters say recent polling gains that have encouraged Democrats do not represent a lasting surge, and they see no statistical evidence of a so-called 'sugar-high' in the numbers — at least for now. Democrats have voiced concern that overly optimistic polling could depress turnout or lead to complacency, but modelers note current data does not yet show the kind of inflated bounce the party fears.

Confusion and anxiety among American voters about the electoral process is emerging as a concern heading into the elections. Commentators are asking whether widespread uncertainty and distrust could depress turnout at the polls, a question that matters for both parties as campaigns push to mobilize supporters.
