How ocean tides create magnetic signals

Ocean tides create tiny magnetic signals

Seawater carries electricity. As ocean tides move this water through Earth's magnetic field, they create tiny magnetic signals of their own. Scientists can measure these signals and use them to learn about heat stored in the ocean.

Studies challenge claims about full moons

37+ studies

At least 37 studies have invalidated claims linking lunar phases to effects such as more psychiatric admissions, traffic accidents, homicides, or suicides.

COVID-19 mortality risk differed enormously between age groups

Early estimates of COVID-19's infection fatality risk showed a steep increase with age. Children faced a much lower risk of dying after infection than very elderly adults, although risk also depended on health, immunity and access to treatment. Population averages could therefore be misleading: two places with similar infection counts might experience very different numbers of deaths.
