At a glance, the sparkling waters of the Southern California coast appear healthy. But a deeper dive into the water's chemical composition reveals high levels of algae and low levels of oxygen.
Living materials, which are made by housing biological cells within a non-living matrix, have gained popularity in recent years as scientists recognize that often the most robust materials are those that mimic nature.
Phytoplankton are microscopic algae living throughout the ocean's surface waters. They can't swim and are at the mercy of the currents and tides. Despite their small size, phytoplankton enable life in the oceans—and throughout ...
Several organisms possess 'ion channels' (gateways that selectively allow charged particles called ions to enter the cells and are integral for cell function) called channelrhodopsins, that can be switched on and off with ...
The results of coral beaching are obvious—stark underwater forests of white coral skeletons—yet the physiological processes of bleaching are not well understood. Now, KAUST researchers show that, long before signs of bleaching ...
The first photosynthetic oxygen-producing organisms on Earth were cyanobacteria. Their evolution dramatically changed the Earth allowing oxygen to accumulate into the atmosphere for the first time and further allowing the ...
A microalga originally isolated from volcanic springs has all it takes to become the next 'superfood' on the market. Compared to Spirulina—a similar organism that's been popular as a food and feed supplement for half a century—Galdieria ...
When geobiology graduate student Katie Maloney trekked into the mountains of Canada's remote Yukon territory, she was hoping to find microscopic fossils of early life. Even with detailed field plans, the odds of finding just ...
Algae colonizing dead coral are upending scientists' ability to accurately assess the health of a coral reef community, according to new work from a team of marine science experts led by Carnegie's Manoela Romanó de Orte ...
New research suggests that the ability of green algae to eat bacteria is likely much more widespread than previously thought, a finding that could be crucial to environmental and climate science. The work, led by scientists ...
