Phys.Org reports that a joint study by the University of Turku and VTT Technical Research Centre of Finland has shown that the ability of photosynthesizing microbial cells to produce biohydrogen from solar energy can be markedly improved by attaching the cells to a transparent nanocellulose film. The method is…

Iridescent algae glow with their own “opals”

Iridescent algae glow with their own “opals”

Rainbow wrack (Cystoseira tamariscifolia) is a type of brown alga found in the Mediterranean Sea and off the Atlantic coast of Europe. In the water, these algae glow. And although there are many glimmering organisms that live in the water, such as bioluminescent jellyfish and lantern fish, most produce their own light…

Fossilized algae hold promise for improved food safety

Fossilized algae hold promise for improved food safety

Researchers have used fossilized algae to take a key step toward being able to more sensitively detect harmful contaminants in food. The findings are important because each year 48 million people get sick from tainted food, 128,000 end up in the hospital, and 3,000 die, according to the Centers for Disease Control…

Using algae to cut antibiotics in feed

Using algae to cut antibiotics in feed

French researchers have been exploring the potential of algae for boosting the immune systems of animals and reducing the use of antibiotics in livestock farming. Past studies have shown that the cell wall of macroalgae contains large quantities of sulphated polysaccharides. These have a range of biological properties, including…

Synthesizing benzene from microalgal oils

Green Car Congress reports that researchers at the University of Konstanz in Germany have now developed a two-step, one-pot process for the synthesis of benzene from the five-fold unsaturated fatty acid eicosapentaenoic acid (EPA), a component of microalgae oils. Their paper is published in the RSC journal…

Streptophyte algae triggered first land plants

Streptophyte algae triggered first land plants

About 510 million years ago, life thrived in Earth’s oceans and freshwater lakes, writes John McPhee in the (Nova Scotia) Chronicle Herald. The ancient ancestors of sea urchins, starfish and jellyfish abounded, as did plants such as red and green algae. There was life on land as well but in much more subtle forms…

Studying year-round cyanotoxins in North Carolina

Studying year-round cyanotoxins in North Carolina

Using two different measurement methods, researchers from North Carolina State University conducted a two-year study of North Carolina’s Jordan Lake in which they monitored toxic algal blooms. The researchers found that multiple cyanotoxins from toxic algal blooms are present year-round, albeit in very low concentrations…

Will shorter winters increase toxic algae?

Will shorter winters increase toxic algae?

Cody Nelson writes for MPRNews.org that a team of University of Minnesota-Duluth researchers wanted to know how shortening winters — and less ice cover on lakes — might increase the presence of harmful algae blooms and impact fisheries. “Aside from people who ice fish, the general assumption is that not much…

The surprisingly rapid evolution of Emiliania huxleyi

The surprisingly rapid evolution of Emiliania huxleyi

As the concentration of carbon dioxide in the atmosphere increases, an increasing amount of CO2 dissolves in the ocean, where it reacts to carbonic acid and acidifies the seawater. As ocean acidification progresses steadily, scientists aim to assess the implications of this process for marine ecosystems…

Stress testing algae’s internal solar panels

Stress testing algae’s internal solar panels

A collaboration between the Benning and Kramer labs at Michigan State University (MSU) is revealing how algae’s internal solar panels constantly grow and shrink in size to adjust to changes in their environments, a crucial system that ensures their hosts stay healthy and alive. The scientists want to use this knowledge…

How single cell life forms evolved into multicellular organisms

How single cell life forms evolved into multicellular organisms

PhD student, Jonathan Featherston, of the Evolution of Complexity Laboratory at the University of the Witwatersrand, Johannesburg, has answered at least part of this question, by decoding the genomic sequence of one of the simplest of all multicellular organisms — the four-celled alga Tetrabaena socialis. His research…

Algal research grant for WesTech, USU and CVWRF

Algal research grant for WesTech, USU and CVWRF

The Utah Science Technology and Research (USTAR) initiative, a technology-based economic development program funded by the state of Utah, has awarded a $175,320 grant for development of a commercial algal application in the removal of nitrogen and phosphorus from municipal wastewater…

Reducing the number of annual algal blooms

Reducing the number of annual algal blooms

The massive annual algal blooms around the world, caused by excess fertilizer from farms and cities running off into water supplies, are having severe human health and economic consequences, with economic damages from the issue costing up to $2.3 trillion annually. New research led by Brigham Young University ecosystem…

Producing algae-based biofertilizer from runoff water

Producing algae-based biofertilizer from runoff water

Minnesota is an agricultural powerhouse that ranks 5th in the nation for total agricultural production. However, this agricultural prosperity may inadvertently threaten the future of the state’s 10,000+ lakes. Agricultural runoff, often high in inorganic nitrogen and phosphorous, can fuel the rapid growth of algae that…

Plant photosynthesis traced to alga 1.25 billion years ago

The world’s oldest algae fossils are a billion years old, according to a new analysis by earth scientists at McGill University in Montréal, Québec, Canada. Based on this finding, the researchers also estimate that the basis for photosynthesis in today’s plants was set in place 1.25 billion years ago…

Developing an integrated algal biorefinery

Yogendra Shastri writes in sciencetrends.com about a recently published study that proposes an integrated biorefinery – co-producing fuel, a low-value high-volume product, with other value-added products such as protein, reduced sugar, and polar lipids – which are high value and low volume…

Chemical communication between algae and bacteria

Chemical communication between algae and bacteria

If green algae of the species Chlamydomonas reinhardtii meet Pseudomonas protegens bacteria, their fate is sealed. The bacteria, measuring only some two micrometers, surround the algae, which are around five times larger, and attack them with a deadly toxic cocktail. The algae lose their flagella, which renders…
