Studies Focus on Warming of Oceans

Oceans absorb carbon dioxide and 90 percent of the heat caused by human activity—making their warming a critical topic for climate research. Two new studies—one on the upper oceans and one on deeper ocean depths—share findings about climate change’s effect on these water bodies. The first study, in the journal Nature Climate Change, provides the first estimate of…

Sperm Works Best in the Winter, Study Finds

Spring may be when a young man’s fancy turns to love, but new evidence suggests that it’s winter when his sperm is at its spunkiest.


“Bears force us to think hard about what we really mean when we say we want to preserve nature. A sample here and there? Multitudes of certain majestic creatures but only token numbers of others – just enough to let us say we didn’t drive them completely extinct?” – Douglas H. Chadwick
