The strange case of Antarctica’s snow turning red

A strange phenomenon variously dubbed by scientists as “watermelon,” “raspberry,” and “blood” snow has affected part of Antarctica. Here the normally white landscape has been transformed into a variegated red. How has this happened?

Algae enzyme converts cooking oil into ready-to-use biofuel

A rare algae enzyme has been shown to be able to convert waste cooking oil, via a photo-bio-catalytic continuous flow system, into a ready-to-use biofuel.

Q&A: Monitoring algal health is key to biofuel development Special

New methods are being applied to identify new and improved algae strains for the production of biofuels. An example is with fluorescence-based, high-throughput flow cytometry, which is being pioneered at the Los Alamos National Laboratory.

Essential Science: Big seaweed bloom triggers pollution concern

Scientists have discovered the biggest seaweed bloom in the world. This is a record-breaking belt of brown algae, from West Africa to the Gulf of Mexico. It’s here to stay for the long-term, and this means ecological trouble.

New microorganism helps produce alternative fuels

Researchers have used genetically engineered algae that can grow three times faster than starch crops and used this to produce biofuel and biochemicals.

Interview: Raising awareness about global toxic algae bloom Special

A new docuseries that raises awareness of the global toxic algae bloom issue, which is caused by excess phosphorus in water, has been developed. To learn more Digital Journal spoke with the team behind the series.

Dealing with toxic algal blooms involves reducing bird poop

Algal blooms are a big problem in many parts of the world. Algae can deplete oxygen levels in lakes and produce toxins which threatened aquatic life. One influencing factor on algal levels is bird feces.

Essential Science: Making more efficient biofuels

Are biofuels the answer to the world’s energy needs or do the problems, including diverting food crops for fuel, carry an unnecessary level of social and economic problems? If biofuels are the answer, how can they be made for efficient?

Assessing the ‘health’ of rivers using DNA analysis

How healthy is a river? One answer is to assess the biodiversity of the waterway. This involves assessing the biodiversity. Current methods involve multiple testing, assessing microscopic marine life. A new method has been proposed based on DNA.

Snow algae accelerate glacier melting

Leeds - A new environmental study indicates that red pigmented snow algae are strongly implicated with the melting Arctic glaciers. Data suggests a 13 percent reduction of the albedo during one year was caused by snow algal blooms.

Northern California crabbing industry gets OK to resume harvest

San Francisco - Northern California's crabbing fleet could return to Pacific Ocean waters as early as next week after state regulators approved the catch as safe to eat, three months after the traditional start of the annual season.

New type of bacteria-powered energy source

As part of the hunt for new types of energy, especially those that are renewable, microbiologists have been examining the properties of marine bacteria. One species, called Cyanothece 51142, is of particular interest.

Five fascinating facts you might not know about sea otters

Sea otters tickle our imaginations. Their charming antics make them the clowns of the sea, and for those of us fortunate enough to live alongside them, they are enchanting. The sight of mother otters cuddling young ones make them even more endearing.

Ciguatera fish poisoning in Florida under reported

As if people don't have enough food borne illnesses to worry about, now we find there is another illness. It's called Ciguatera toxin poisoning. It is estimated that the number of cases of this food borne illness has been greatly under-reported

Algae from waterways could serve as a biofuel

Detroit - Water-borne algal blooms from farm fertilizer runoff cause environmental pollution and potential health concerns. Scientists have a new solution: collecting up the algae to make biofuels.

Potential antimalarial drug made from algae

Scientists have used algae to produce a malaria parasite protein. When the algae-produced protein is paired with an immune-boosting cocktail, studies showed generated antibodies in mice were able to eliminate a mosquito infection.

Do something really dumb today? Blame it on the 'stupidity virus'

When the media got hold of the story about a virus found in the throats of as much as 45 percent of the population, that was news. Learning the virus affects human behavior and cognitive thinking, they immediately called it the "stupidity virus."

A virus found in lakes may be literally changing the way people think

While conducting a totally separate experiment, a group of scientists from Johns Hopkins and the University of Nebraska accidentally discovered something unexpected and potentially disturbing.

Switching algae on and off may help with cancer and biofuels

Scientists have found a way to switch certain cells on and off – a type of “cellular snooze button”. Knowing this could potentially help researchers improve biofuel production and cancer detection.

Hot spring bacteria use red light for growth

Scientists have long been puzzled how bacteria grow in the near darkness of hot springs. It transpires that the bacteria can harness small quantities of red light from the little sunlight that permeates the depths.

Ohio under 'State of Emergency' Toledo's water contaminated

Toledo - About 2 a.m. Saturday morning, officials in Toledo, Ohio issued a "do not drink" warning, declaring the city's water supply contaminated with the toxin microcystin. Ohio Gov. John Kasich declared a State of Emergency, allowing water to be brought in.

Norway experiments with fish food made from carbon dioxide

Oslo - Norwegian scientists are to carry out an experiment where captured carbon dioxide is turned into food, in form of algae, for farmed fish.

Urban Algae Canopy produces a forest's worth of oxygen

London - A London based architecture firm is combining algae with their buildings to produce more oxygen. It is a combination of architecture, biology, and technology that will be unveiled at Expo 2015.

The rise of 'rock snot', a mysterious algae

Dartmouth - An increasingly common algal growth dubbed 'rock snot', found in rivers the world over, is caused by changing environmental conditions.

Efficient way of making raw ingredient for biofuel Special

Biochemists have begun building a one-hectare pilot unit for the production of microalgae in Portugal. The aim is to produce microalgae biomass for biodiesel production in a sustainable manner.

Algae converted to crude oil in less than one hour

Scientists have replicated the process whereby fossil fuels were created. Instead of this taking several millennia the process has been completed in under sixty minutes.

Tricking algae into making biofuels

Scientists have found a way to manipulate the internal clock of algae into thinking it is permanent daylight. This technique could lead to increased biofuel production.

Warming climate is helping to spread toxic algae on Lake Erie

Toledo - A warming climate, coupled with questionable soil management practices, has created ideal conditions for an explosion of toxic blue-green algae growth on Lake Erie. Alarm sirens blare as government officials work to find a solution to the algae problem.

Climate change impacts on the oceanic food chain

Climate change appears to be affecting the starting point of the ocean’s food chain. Changing climate is affecting the types of microscopic organisms found in the seas, with potential consequences for marine life and human health.

Massive algae bloom attracting beach-goers in Qingdao, China

Qingdao - Coastal areas of the Yellow Sea, located between the coast of China and the Korean peninsula, are now green as a result of the extraordinary proliferation of algae in the water. The excessive algal growth may be caused by industrial pollutants.
