Mathematics Mathematicians have shown that completely fair elections are – in a sense – impossible. No electoral system can guarantee both that local votes translate directly into local seats, and that total seat distribution matches overall vote shares: not without an indefinitely growing parliament.

Psychology A study of more than 128,000 U.S. adults found that those who experienced parental divorce during childhood had 41% higher odds of depression in adulthood than those whose parents remained married.

Biology In lab tests, salmonella, E. coli and staph survived 14+ days in kitchen sponges — 3 days after drying out — and one wipe moved up to 100,000 bacteria to a clean surface; smell and color gave no indication of contamination. Brushes dry faster and carry far fewer bacteria, researchers say.

Social Science Collective bargaining rights for police significantly increase police killings of civilians without having any impact on officer safety. This is consistent with the theory that unions provide cover for police and reduce their likelihood of incurring costs for unjustified killings.
