'Milking' algal cells proves efficient alternative
Biofuel researchers have dramatically improved microalgae hydrocarbon productivity by using non-destructive extraction, akin to 'milking' algal cells as opposed to the conventional harvest and destruction.
When hungry, Gulf of Mexico algae go toxic
When Gulf of Mexico algae don't get enough nutrients, they focus their remaining energy on becoming more and more poisonous to ensure their survival, according to a new study by scientists from North Carolina ...
Microswimmers hit the wall (w/ video)

Improving water quality can help save coral reefs (w/ Video)
Research from the University of Southampton and the National Oceanography Centre, Southampton has found that an imbalance of nutrients in reef waters can increase the bleaching susceptibility of reef corals.
Synchronized swimming of algae
Using high-speed cinematography, scientists at Cambridge University have discovered that individual algal cells can regulate the beating of their flagella in and out of synchrony in a manner that controls their swimming trajectories. ...
'Hot spot' for toxic harmful algal blooms discovered off Washington coast
A part of the Strait of Juan de Fuca, which separates Washington state from Canada's British Columbia, is a potential "hot spot" for toxic harmful algal blooms affecting the Washington and British Columbia coasts.
Magnificent blue glow of Hong Kong seas also disturbing
Eerie fluorescent blue patches of water glimmering off Hong Kong's seashore are magnificent, disturbing and potentially toxic, marine biologists say.
Study finds algal cells create fat more quickly than thought, could aid biofuel research
(Phys.org) —Many scientists see great promise in algae as a new source of oil—a sustainable, environmentally sound way to break the world's fossil fuel dependence.
Trace element's central role in harmful algal blooms
Four years after it first appeared and devastated the scallop industry, the algal masses of Aureococcus anophagefferens that turned the bays of Long Island, NY brown disappeared. The alga's genome sequen ...
Biodiesel algae: Starvation diets damage health
It may be better to tolerate lower oil content in algae grown for biodiesel to boost growth and overall productivity, says research from the University of Sheffield.
