    A massive patch of bright orange material washed up on the Alaskan coast, and has scientists baffled. The substance, which experts don't believe is man-made, could possibly be algae, but a kind no one has seen before. "There doesn't appear to be any evidence of a release of oil or hazardous substances at this time, but we're continuing to investigate and trying to get lab determinations on what exactly the material is," Emanuel Hignutt, analytical chemistry manager for Alaska's Environmental Health Laboratory told CNN. "What it is - an algal bloom, or something inorganic - that's what we're working to...
  • Oozing biofuel: Algae could solve world's fuel crisis (organisms need sunlight, CO2, seawater)

    Genetically modified blue and green algae could be the answer to the world's fuel problems. Bioengineers have already developed algae that produce ethanol, oil and even diesel -- and the only things the organisms need are sunlight, CO2 and seawater. Biochemist Dan Robertson's living gas stations have the dark-green shimmer of oak leaves and are as tiny as E. coli bacteria. Their genetic material has been fine-tuned by human hands. When light passes through their outer layer, they excrete droplets of fuel. "We had to fool the organism into doing what I wanted it to do," says Robertson, the head...
  • Melting icebergs fertilize ocean

    Efforts to remove climate-warming carbon dioxide from Earth’s atmosphere appear to be getting a helping hand from a surprising source: the iron in meltwater from Antarctic icebergs. Icebergs calving off of Antarctica are shedding substantial iron — the equivalent of a growth-boosting vitamin — into waters starved of the mineral, a new set of studies demonstrates. This iron is fertilizing the growth of microscopic plants and algae, transforming the waters adjacent to ice floes into teeming communities of everything from tiny shrimplike krill to fish, birds and sometimes mammals.

    Organism's ability to distinguish strontium from calcium could help in dealing with nuclear waste. Common freshwater algae might hold a key to cleaning up after disasters such as Japan's Fukushima nuclear accident, scientists said yesterday at a meeting of the American Chemical Society in Anaheim, California. The algae, called Closterium moniliferum, are members of the desmid order, known to microbiologists for their distinctive shapes, said Minna Krejci, a materials scientist at Northwestern University in Evanston, Illinois. But the crescent-shaped C. moniliferum caught Krejci's eye because of its unusual ability to remove strontium from water, depositing it in crystals that form...

    Ancient food source may offer neuroprotectionNutritional supplementation with Spirulina, a nutrient-rich, blue-green algae, appeared to provide neuroprotective support for dying motor neurons in a mouse model of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, University of South Florida neuroscientists have found. Although more research is needed, they suggest that a spirulina-supplemented diet may provide clinical benefits for ALS patients. A spirulina dietary supplement was shown to delay the onset of motor symptoms and disease progression, reducing inflammatory markers and motor neuron death in a G93A mouse model of ALS. Spirulina, an ancient food source used by the...

    Everything is grubby in countries run by statist moonbats — even dishes fresh out of the dishwasher. A couple of months ago, Sandra Young from Vernon, Fla., started to notice that something was seriously amiss with her dishes. "The pots and pans were gray, the aluminum was starting to turn black, the glasses had fingerprints and lip prints still on them, and they were starting to get this powdery look to them," Vernon says. "I'm like, oh, my goodness, my dishwasher must be dying, I better get a new dishwasher." But others are having the same problem all across the...
  • Destruction of Giant Algae Doughnut Threatens Lake Michigan (Quagga mussels eating phytoplankton)

    An invasive species of mussel called quagga has recently begun eating its way through the phytoplankton population of Lake Michigan, which could have dire effects on the lake's ecosystem, scientists now warn. A giant ring of phytoplankton (microscopic plants such as algae) was discovered in Lake Michigan in 1998 by Michigan Technological Universitybiologist W. Charles Kerfoot and his research team. The "phytoplankton doughnut" is formed when winter storms kick up nutrient-rich sediment along the southeastern shore of the lake. The disturbed sediments begin circulating in a slow-moving circle with the lake's currents, which provides a massive supply of food for...

    Scientists have stumbled across the first example of a photosynthetic organism living inside a vertebrate's cells. The discovery is a surprise because the adaptive immune systems of vertebrates generally destroy foreign biological material. In this case, however, a symbiotic alga seems to be surviving unchallenged — and might be giving its host a solar-powered metabolic boost. Algae cohabit with salamander embryos in their eggs — and inside their cells.T. LEVIN/PHOTOLIBRARY.COM The embryos of the spotted salamander (Ambystoma maculatum) have long been known to enjoy a mutualistic relationship with the single-celled alga Oophila amblystomatis. The salamanders' viridescent eggs are coloured by...

    SAN DIEGO — In a laboratory where almost all the test tubes look green, the tools of modern biotechnology are being applied to lowly pond scum. Foreign genes are being spliced into algae and native genes are being tweaked. Different strains of algae are pitted against one another in survival-of-the-fittest contests in an effort to accelerate the evolution of fast-growing, hardy strains. The goal is nothing less than to create superalgae, highly efficient at converting sunlight and carbon dioxide into lipids and oils that can be sent to a refinery and made into diesel or jet fuel.

    BEIJING (AFP) – A floating expanse of green algae floating off China's eastern seaboard is growing and spreading further along the coast, state-run media has reported. The algae bloom has expanded by about 50 percent since it was first reported by state media earlier in the week to 320 square kilometres (120 square miles), or about four times the size of Hong Kong island, Xinhua news agency said. The algae island was previously situated several kilometres off the coast of Shandong province but has expanded southwards to waters off neighbouring Jiangsu, it said in a dispatch late Wednesday.

    Frederic Scheer is biding his time, convinced that by 2013 the price of oil will be so high that his bio-plastics, made from vegetables and plants, will be highly marketable. Scheer, 55, is the owner of Cereplast, a company that designs and makes sustainable plastics from starches found in tapioca, corn, wheat and potatoes. He has believed for the past 20 years that the price of oil will eventually make petroleum-based plastics obsolete and clear the way for his alternative. "The tipping point for us is 95 dollars a barrel," he said. At that price "our product becomes cheaper" than...

    Fungi are single or multi-celled organisms that break down organic materials, such as rotting wood, in order to absorb their nutrients. Neither plant nor animal, they range from mushrooms to single-celled yeast. Scientists were investigating organic chemicals trapped in an Italian sedimentary rock formation when they found evidence that an extinct fungus feasted on dead wood during a time when the world’s forests had been catastrophically eradicated.[1] What could have caused such a universal effect on forests, and why does organic material remain in rocks that are supposedly 251.4 million years old?...

    WAUSAU, Wis. — Waterways across the upper Midwest are increasingly plagued with ugly, smelly and potentially deadly blue-green algae, bloomed by drought and fertilizer runoffs from farm fields, that's killed dozens of dogs and sickened many people. Aquatic biologists say it's a problem that falls somewhere between a human health concern and a nuisance, but will eventually lead to more human poisoning. State officials are telling people who live on algae-covered lakes to close their windows, stop taking walks along the picturesque shorelines and keep their dogs from drinking the rank water.

    Algae, paper and salt-water are the key components of thin and flexible new batteries, report Swedish researchers. Cellulose obtained from the bright green Cladophora algae proved to be key to the project, as it boasts a unique nanostructure with a high surface area. Although the batteries have lower voltage and power density than conventional batteries, their low cost and flexibility hold great promise for applications where metal-based batteries are impractical. The research is the product of a collaboration between two teams at Uppsala University in Sweden: Maria Strømme's group, who identified the potential of the algal cellulose, and Leif Nyholm's group, who...

    There are two big problems associated with extracting liquid fuel from algae: getting the algae out of the water, and then getting the oil out of the algae. The pumps and centrifuges required to do this consume a lot of energy. A California company, LiveFuels, is trying out a new, less energy-intensive approach: It is feeding the algae to small fish — and letting them do the job of harvesting. After the fish fatten up, workers catch them in nets and process them for oil (as well as protein for animal feed). This is a bit like gathering whale oil,...

    The method, called catalytic hydrothermal gasification, creates natural gas out of algae - more quickly, more efficiently and at higher yields than other biofuel processes. Genifuel expects the process also requires less capital investment. The license agreement moves this technology for renewable energy production a step closer to commercial reality. Battelle operates PNNL for DOE. "Algae and other aquatic biomass hold significant promise for our country's ability to produce renewable energy domestically," said Genifuel President Jim Oyler. "At Genifuel we have developed efficient growth and harvesting techniques for the aquatic biomass. With this gasification process, we can convert the biomass...
