Old carbon reservoirs unlikely to cause massive greenhouse gas release, study finds

Tundra (stock image).Credit: © Georgys / Adobe Stock Permafrost in the soil and methane hydrates deep in the ocean are large reservoirs of ancient carbon. As soil and ocean temperatures rise, the reservoirs have the potential to break down, releasing enormous quantities of the potent greenhouse gas methane. But would this methane actually make it to […]

A plan to save Earth's ocean

At least 26 per cent of our oceans need urgent conservation attention to preserve Earth’s marine biodiversity, a University of Queensland-led international study has found.advertisement Dr Kendall Jones said the international community needed to rapidly increase marine conservation efforts to maintain the health of the world’s oceans. “Preserving a portion of habitat for all marine […]

Let there be 'circadian' light

Researchers said the wavelengths at sunrise and sunset have the biggest impact to brain centers that regulate our circadian clock and our mood and alertness.advertisement Their study, “A color vision circuit for non-image-forming vision in the primate retina,” published in Current Biology Feb. 20, identifies a cell in the retina, which plays an important role in signaling […]
