New species highlight biodiversity hotspot

New species highlight biodiversity hotspot

Algae have long been identified and classified by their physical appearance, such as their color and branching. However, reliance on the form and structure of these organisms has made it challenging to determine diversity and map distribution. Molecular technologies have changed that. As scientists use DNA analysis…

Species diversity in algal biofuel systems

Species diversity in algal biofuel systems

When growing algae in outdoor ponds as a next-generation biofuel, a naturally diverse mix of species will help reduce the chance of crop failure, according to a federally funded study by University of Michigan researchers. U-M ecologist Bradley Cardinale and his colleagues found that growing multiple algal species…

High-performance bioplastics from seaweed

High-performance bioplastics from seaweed

Park Se-young, at Arirang News, writes about a Korean research team at Ewha Womans University, in Seoul, South Korea that has developed the technology to manufacture eco-friendly, high performance, bioplastics using seaweed. This technique is the first of its kind to use lipids from algae, according to the scientists…

Warning of toxic algae blooms before they develop

Warning of toxic algae blooms before they develop

The Fish Site reports on a new study, published in the journal Proceedings of the National Academy of Sciences, demonstrating that automated monitoring systems that identify “regime shifts” – such as rapid growth of algae and then depletion of oxygen in the water – can successfully predict full-scale algae blooms…

Tracking changes at the base of the food chain

Tracking changes at the base of the food chain

Danielle Kaeding reports for Wisconsin Public Radio that a warming climate is transforming the base of the food chain in the Great Lakes, according to a new study published recently in the scientific journal Limnology and Oceanography. Researchers say rising lake temperatures could spell changes for the rest…

ARPA-E’s MARINER project seeks macroalgae productivity

ARPA-E’s MARINER project seeks macroalgae productivity

The United States has the world’s largest marine Exclusive Economic Zone, an area of ocean along the nation’s coastlines which is equivalent to the total land area of all 50 states. The nation has the potential to utilize this resource to build and grow a thriving marine biomass industry for the production of fuels, chemicals…

How cryptophyte algae harvest light energy

How cryptophyte algae harvest light energy

It’s the single-celled photosynthetic organisms at the top layer of the ocean that absorb the most sunlight. Underneath, in the sublayers, are cryptophyte algae that must compete for photons that have filtered through the upper depths. The key to their survival, a study published on December 8 in Chem reveals…
