Latest Green algae Stories
It was previously thought that land plants evolved from stonewort-like algae. However, new research published in BioMed Central's open access journal BMC Evolutionary Biology shows that the closest relatives to land plants are actually conjugating green algae such as Spirogyra.Ancestors of green plants began to colonise the land about 500 million years ago and it is generally accepted that they evolved from streptophyte algae (a group of green, fresh water algae). But this group of algae is...
Naughtybitsâ„¢ are algae tabs like the ones that healed the Hiroshima and Chernobyl victims from radiation poisoning. The Fukushima disaster is a reminder that algae removes toxins of all kinds. It's been the best kept secret for 2 billion years. Boston, MA (PRWEB) April 11, 2011 As the Fukushima nuclear power plant catastrophe continues to unfold, Japan's radiation levels continue to climb and threaten the health of more people. While the impact in the USA is greatly reduced, the...
A species of algae long known to associate with spotted salamanders has been discovered to live inside the cells of developing embryos, say scientists from the U.S. and Canada, who report their findings in this week's Proceedings of the National Academy of Sciences.This is the first known example of a eukaryotic algae living stably inside the cells of any vertebrate."It raises the possibility that more animal/algae symbioses exist that we are not aware of," said Indiana University...
A team of biologists has discovered an entirely new group of algae living in a wide variety of marine and freshwater environments. This group of algae, which the researchers dubbed "rappemonads," have DNA that is distinctly different from that of other known algae. In fact, humans and mushrooms are more closely related to each other than rappemonads are to some other common algae (such as green algae). Based on their DNA analysis, the researchers believe that they have discovered...
Tiny creatures may play a crucial role in mixing ocean nutrientsTwo separate research groups are reporting groundbreaking measurements of the fluid flow that surrounds freely swimming microorganisms. Experiments involving two common types of microbes reveal the ways that one creature's motion can affect its neighbors, which in turn can lead to collective motions of microorganism swarms. In addition, the research is helping to clarify how the motions of microscopic swimmers produces large...
Scientists and engineers seek to meet three goals in the production of biofuels from non-edible sources such as microalgae: efficiency, economical production and ecological sustainability. Syracuse University's Radhakrishna Sureshkumar, professor and chair of biomedical and chemical engineering in the L.C. Smith College of Engineering and Computer Science, and SU chemical engineering Ph.D. student Satvik Wani have uncovered a process that is a promising step toward accomplishing these three...
One of the most pivotal steps in evolution-the transition from unicellular to multicellular organisms-may not have required as much retooling as commonly believed, found a globe-spanning collaboration of scientists led by researchers at the Salk Institute for Biological Studies and the US Department of Energy's Joint Genome Institute.A comparison of the genomes of the multicellular algae Volvox carteri and its closest unicellular relative Chlamydomonas reinhardtii revealed that multicellular...
Scientists have for the first time determined the complete genome sequence of a brown alga and opened a new door to the understanding of multicellularity and photosynthesis. With the world's first complete sequencing of a brown algal genome, an international research team has made a big leap towards understanding the evolution of two key prerequisites for higher life on Earth - multicellularity and photosynthesis. As the internationally renowned science magazine "Nature" reported in...
TORRANCE, Calif., May 14 /PRNewswire/ -- Summer action movies may call for suspension of disbelief from audiences, but one superhero's penchant for a chlorophyll-rich drink to detoxify his body has real benefits, according to one medical expert. (Photo: http://www.newscom.com/cgi-bin/prnh/20100514/LA04961) "Chlorophyll has been shown to help reduce contaminants found in everyday life and that build up in the body over time," explains Mark Drucker, M.D. and co-founder of the Center for...
TORRANCE, Calif., April 26 /PRNewswire/ -- Sun Chlorella Corporation, an international manufacturer of premium human and animal-grade chlorella green food products, confirmed today that its sponsored study, "Anti-inflammatory Effect of Chlorella pyrenoidosa on Chronic Dermatitis in Beagles," showed significant observed improvement in dogs suffering from this agitated dermal condition. The four-week, veterinary-supervised study involved subjects suffering from pre-existing dermatitis,...
