Can seagrass help fight ocean acidification?

Seagrass meadows could play a limited, localized role in alleviating ocean acidification in coastal ecosystems, according to new work led by Carnegie's David…

Solar powered sea slugs shed light on search for perpetual green energy

In an amazing achievement akin to adding solar panels to your body, a Northeast sea slug sucks raw materials from algae to provide its lifetime supply of…

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

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…

Light green plants save nitrogen without sacrificing photosynthetic efficiency

“Leaves up at the top of the canopy are really greedy–they absorb a lot of light and don't let much down to their brothers and sisters below them,” said…

Water world

Researchers at Washington University in St. Louis have traced the paths of three water channels in an ancient photosynthetic organism to provide the first…

How Photosynthetic Cells Deal with a Lack of Iron

International researchers working in collaboration with Professor Wolfgang R. Hess and Dr. Jens Georg, both from the University of Freiburg’s Faculty of…

Glacier bacteria’s contribution to carbon cycling

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a…

Older and more diverse forests are more stable in taking up carbon dioxide

The total uptake of carbon dioxide by ecosystems via photosynthesis is the largest flux in the global carbon cycle. The intensity of this “natural CO₂ pump”…

Ultrafast lasers reveal light-harvesting secrets of photosynthetic algae

Now, researchers at Princeton University have revealed a mechanism that enhances the light harvesting rates of the cryptophyte algae Chroomonas mesostigmatica….

Surprising role of bacterial genes in evolution

Sometimes a “host” organism can obtain genes from another organism that resides within its own cell (called an endosymbiont) through a process known as…
