Less life: Limited phosphorus recycling suppressed early Earth’s biosphere

The amount of biomass — life — in Earth’s ancient oceans may have been limited due to low recycling of the key nutrient phosphorus, according to new research by the University of Washington and the University of St. Andrews in Scotland. The research, published online Nov. 22 in the journal Science Advances, also comments on the role of volcanism in supporting Earth’s early biosphere — and may even apply to the search for life on other worlds.

A new University of Washington study points to yet another human factor that hampers the ability of fish to reproduce: the timing of our fishing seasons.

Changing the faces and future of conservation

The Doris Duke Conservation Scholars program at the UW was started in 2014 when it became clear that the environmental movement had made no strides in decades to address its lack of racial and gender diversity, a problem commonly known as the Green Ceiling. Simply put, no more than 12 percent of all employees in non-governmental organizations and foundations that work with natural resources could be described as ethnic minority or multiracial.
