How plants protect photosynthesis from oxygen

During the daytime, plants convert the Sun's energy into sugars using photosynthesis, a complex, multi-stage biochemical process. New work from a team including Carnegie's Mark Heinnickel, Wenqiang Yang, and Arthur Grossman ...

Lake Erie: Warmest in summer, coldest in winter

When it's 20 below, Dr. Michael Twiss, professor at Clarkson University, has been known to clear the snow and lie down on the thick ice of a frozen lake and stare up at the Northern Lights. But for all his winter preparedness, ...

Photobioreactor enables systems biology studies of cyanobacteria

A novel photobioreactor designed and developed at Pacific Northwest National Laboratory for cultivating photosynthetic bacteria and microalgae will be featured in the journal Bioresource Technology. PNNL researchers are using ...

Tiny algae shed light on photosynthesis as a dynamic property

Many of the world's most important photosynthetic eukaryotes such as plants got their light-harnessing organelles (chloroplasts) indirectly from other organisms through endosymbiosis. In some instances, this resulted in algae ...

Small bacteria helping big things grow in the ocean

Around 71 per cent of the Earth's surface is made up of salt-water oceans - that's 98 per cent of all water. The ecosystems that exist beneath their surface are diverse and vibrant. Their sheer scale, however, means that ...

Think pink! Success of pink bacteria in oceans of the world

Marine bacteria of the Roseobacter clade are found to be spread widely throughout the oceans of this planet from the tropics to as far as Antarctica. They live freely in the water, in sediments and as symbiotic partners of ...
