Before exercise training, the older adults were 59% weaker than the younger adults, but after the training the strength of...

Alarming acceleration in CO2 emissions worldwide

The spatial distribution and magnitude of these trends suggest a shift from a clockwise to a counterclockwise pattern prevalent prior to the 1990s. Changes in Arctic Ocean circulation are important to...
