Changes in Antarctic marine ecosystems

Intensity of phytoplankton production during Antarctic summer affects the structure of seafloor ecosystems. Understanding the evolution of the polar sea ice is not enough to study the effects of the…

Discovery of a new catalytic intermediate in biological water oxidation

Computational simulations performed by the Pantazis group combined with spectroscopic studies led to the discovery of a new catalytic intermediate in water oxidation. One of the greatest ambitions of modern…

Novel technology for the selection of single photosynthetic cells

Novel technology for the selection of single photosynthetic cells for industry and ecosystem understanding. You might need a microscope to witness the next agricultural revolution. New research, published in the…

New study tracks sulfur-based metabolism in the open ocean

A study by University of Washington oceanographers, published this summer in Nature Microbiology, looks at how photosynthetic microbes and ocean bacteria use…

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…

Genome sequence of fuel-producing alga announced

The report, in Genome Announcements, comes after almost seven years of research, according to Dr. Tim Devarenne, AgriLife Research biochemist and principal…

Ocean toxicity hampered the rapid evolution of complex life

“In the article we argue that when we first see the appearance of complex life on Earth, is when life have developed mechanisms to resist catastrophic chemical…

Ancient rocks record first evidence for photosynthesis that made oxygen

“Rock from 3.4 billion years ago showed that the ocean contained basically no free oxygen,” says Clark Johnson, professor of geoscience at UW-Madison and a…

Engineering alternative fuel with cyanobacteria

Micro-algal fuels might be one way to reduce the nation’s dependence on foreign energy. Such fuels would be renewable since they are powered by sunlight. They…
