Researchers discover source of essential nutrients for mid-ocean algae
For almost three decades, oceanographers have been puzzled by the ability of microscopic algae to grow in mid-ocean areas where there is very little nitrate, an essential algal nutrient. In this week's issue ...
Sloth truly deserves its name, biologists say
Imagine a creature so slothful that it snacks off its own fur and budges only once a week for a bowel movement.
Old concrete can protect nature
Usually we think of demolished concrete walls and floors as environmental contaminants, but in fact this material may turn out to be a valuable resource in nature protection work. This is the conclusion from ...
Air pollution stunts coral growth, research shows
A new study has found that pollution from fine particles in the air – mainly the result of burning coal or volcanic eruptions – can shade corals from sunlight and cool the surrounding water resulting ...
The 'slippery slope to slime': Overgrown algae causing coral reef declines
(Phys.org)—Researchers at Oregon State University for the first time have confirmed some of the mechanisms by which overfishing and nitrate pollution can help destroy coral reefs – it appears they allow ...
Loss of 'lake lawnmowers' leads to algae blooms
Unprecedented algae growth in some lakes could be linked to the decline of water calcium levels and the subsequent loss of an important algae-grazing organism that helps keep blooms at bay.
Study determines theoretical energy benefits and potential of algae fuels
It's theoretically possible to produce about 500 times as much energy from algae fuels as is needed to grow the fuels, according to a new study by researchers at The University of Texas at Austin.
Ancient bacterial mats may have been key to first mobile animals
Watching Proteins Direct Crystal Growth One Step at a Time (w/ Video)
(PhysOrg.com) -- Scientists at Berkeley Lab's Molecular Foundry imaged the growth of protein-studded mineral surfaces with unprecedented resolution and provided a glimpse into how living systems engineer key ...
Phosphorus runoff can be slowed by changing farming practices, researchers say
(PhysOrg.com) -- Two recent studies by Iowa State University researchers show that phosphorus runoff into Iowa's rivers, streams and lakes can be slowed by farmers changing how they plant and fertilize their ...
Algae may be a potential source of biofuels and biochemicals even in cool climate
Algae are organisms useful in many ways in the transition towards a bio-economy. Even in a cool climate as in Finland, algae might be used to produce biochemicals and biofuels, besides use in capture of industrial ...
Toxic algae blooms cause illness, death in dogs
Dogs are known to play, swim and lap up water in lakes and ponds, but these simple joys can lead to illness and even fatal poisoning when harmful algae blooms muck up the water.
A 'B12 shot' for marine algae? Scientists find key protein for algae growth in the ocean
Scientists have revealed a key cog in the biochemical machinery that allows marine algae at the base of the oceanic food chain to thrive. They have discovered a previously unknown protein in algae that grabs an essential ...
As dams loom, Mekong fishermen fear for their future
The waters of the mighty Mekong have sustained generations of families but nowadays its fishermen often find their nets empty and fear hydropower mega-dams will destroy their livelihoods.
