How algal cells recycle components during scarcity

To cope with changes in its aquatic environment and the nutrient deficiencies that may result, Chlamydomonas reinhardtii, a mobile single-cell alga, must adapt its metabolism for subsistence, notably in terms of sugar. The latter is produced by photosynthesis. To this end, plants and algae use internal cell structures…

Chlamydomonas study shows nature’s coping mechanism

A small freshwater algal strain that has evolved to live in harsh seawater is giving scientists insight into how living things adapt to changes in their environment. The findings could help scientists better understand how species have been able to adapt to major shifts of circumstances in the past, such as transferring from…

Chlamy — a cure for blindness?

Sarah Zhang writes in Wired Magazine that the single-cell green algae Chlamydomonas reinhardtii have an eyespot that makes use of light-sensitive proteins. One of them is called channelrhodopsin-2. This algal protein, transplanted into the human retina, could one day restore sight to the blind…

Gently stressing algae for higher lipids

Some algae like Chlamydomonas reinhardtii (or “Chlamy,” as it’s known to its large research community) produce energy-dense oils or lipids when stressed, and these lipids can then be converted into fuels. However, researchers walk a fine line in not killing the goose that lays the golden eggs, in this case, stressing…

Swimming algae decode living fluid dynamics

None of us would be alive if sperm cells didn’t know how to swim, or if the cilia in our lungs couldn’t prevent fluid buildup. But we know very little about the dynamics of so-called “living fluids,” those containing cells, microorganisms or other biological structures. Understanding the behavior of living fluids starts…

Bioprinting algae in 3D

Brian Krassenstein, writing in 3Dprint.com, goes deeper into the recent paper in Engineering in Life Sciences journal discussing the impact 3D bioprinting will have in the field of medicine. As several companies are already printing living human tissue, it’s only a matter of time before many ailments can be halted via…

Discovering algae’s suicidal tendencies

The question of why an individual would actively kill itself has been an evolutionary mystery. Death could hardly provide a fitness advantage to the dying individual. However, a new study has found…

Hydrogen production efficiency discovery in green algae

That green algae can produce hydrogen under certain conditions has been known and studied for about 15 years, but low efficiency has been a problem, i.e. the amount of energy…

Sapphire Announces Algal Chloroplast Genome Development

Sapphire Energy, Inc., has announced that Nucleic Acids Research Journal has published its white paper, “An Exogenous Chloroplast Genome for Complex Sequence Manipulation in Algae.” As the site of…

ISU Researchers Pair Genes to Up Photosynthetic Carbon Conversion

Researchers at Iowa State University, in Ames, IA, are exploring the effects of controlling the expression of two algal genes that regulate the uptake of CO2 for photosynthesis. In the experiments performed…

Algae Engineering Kits from GeneArt®

Life Technologies has announced that they will soon be releasing their New GeneArt® Algae Engineering Kits for Chlamydomonas reinhardtii and Synechococcus elongatus, the first…
