R.I. nitrogen cycle differs in bay and sound
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it's a major factor just a little farther out into Rhode Island Sound. Scientists traced ...
Halving your meat intake would be good for the environment
We should all swap at least half of the meat, dairy products and eggs we eat with cereals, lentils, beans and other plant-based foods to help reduce nitrogen pollution, lower greenhouse gas emissions and ...
Nitrogen pollution, climate and land use
A new report quantifies for the first time how much our food choices affect pollutant nitrogen emissions, climate change and land-use across Europe.
Study resolves controversy over nitrogen's ocean 'exit strategies'
A decades-long debate over how nitrogen is removed from the ocean may now be settled by new findings from researchers at Princeton University and their collaborators at the University of Washington.
Volcanic eruptions may affect oceanic microbial processes
Extensive, explosive volcanic eruptions may disrupt a crucial aspect of the global nitrogen cycle, say researchers who have investigated ash deposits on the ocean floor.
Legume research uncovers nitrogen uptake genes
(Phys.org) —Increased nitrogen-use efficiency of plants and an associated reduced need for nitrogen-based fertilisers may be a step closer following University of Adelaide research on legumes.
Nitrogen source determined significant for inflorescence development in Phalaenopsis
The Phalaenopsis orchid, also known as the moth orchid, is the most important pot flower in terms of market value in the world's major floriculture markets. Because nitrogen significantly affects the growth ...
Simulations to reduce emissions from road transport
Researchers at the UPM are developing a methodology to estimate atmospheric emissions from road transport that will help to make environmental decisions.
Paleo diet didn't change – the climate did
Why were Neanderthals replaced by anatomically modern humans around 40,000 years ago? One popular hypothesis states that a broader dietary spectrum of modern humans gave them a competitive advantage on Neanderthals. ...
Seabird guano releases more ammonia at tropics
Seabird guano emits more ammonia into the atmosphere in warmer and wetter climates, scientists have found.
Winter harvest boosts feedstock security
A drought two years ago left dairy farmers with a feed shortage and a lingering question: Can the off-season generate a second harvest? Results from a large collaborative project led by the Cornell Nutrient ...
Colored diamonds are a superconductor's best friend
(Phys.org) —Flawed but colorful diamonds are among the most sensitive detectors of magnetic fields known today, allowing physicists to explore the minuscule magnetic fields in metals, exotic materials and ...
Sea surface is a sink for nitrogen oxides at night
The surface of the sea takes up nitrogen oxides that build up in polluted air at night, new measurements on the coast of southern California have shown. The ocean removes about 15 percent of these chemicals ...
Leech has a remarkably high tolerance to freezing and thawing
Imagine you're a leech, happily making a living on a turtle in some quiet, freshwater pond. What do you do when winter comes and temperatures in your warm little habitat begins to dip below freezing?
