Identical virus, host populations can prevail for centuries
A Woods Hole Oceanographic Institution (WHOI) scientist, analyzing ancient plankton DNA signatures in sediments of the Black Sea, has found for the first time that the same genetic populations of a virus and its algal host ...
Loch fossils show life harnessed sun and sex early on
Remote lochs along the west coast of Scotland are turning up new evidence about the origins of life on land.
Did Phosphorus Trigger Complex Evolution -- and Blue Skies?
(PhysOrg.com) -- The evolution of complex life forms may have gotten a jump start billions of years ago, when geologic events operating over millions of years caused large quantities of phosphorus to wash ...
New research could help predict red tide
(PhysOrg.com) -- Not far beneath the ocean's surface, tiny phytoplankton swimming upward in a daily commute toward morning light sometimes encounter the watery equivalent of Rod Serling's Twilight Zone: a ...
'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)
(Phys.org)—New research reveals what happens when swimming cells such as spermatozoa and algae hit a solid wall, and has implications for applications in diagnostics and biofuel production.
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.
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.
Scientists link nutrient pollution to coral bleaching
Too many nutrients can put corals at risk, a new study shows. Excessive nitrogen in the water affects their ability to cope with rising water temperatures and other environmental pressures, making them vulnerable ...
