Strangers invade the homes of giant bacteria
Life is not a walk in the park for the world's largest bacteria, that live as soft, noodle-like, white strings on the bottom of the ocean depths. Without being able to fend for themselves, they get invaded ...
Double effort needed to clean up Thames
The River Thames will fail to meet pollution standards in 2015 unless farmers use 20 per cent less fertiliser and water companies reduce phosphorus discharges from sewage treatment, according to a new study.
World changing technology enables crops to take nitrogen from the air
A major new technology has been developed by The University of Nottingham, which enables all of the world's crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.
Unexpected behavior of well-known catalysts
Industrial palladium-copper catalysts change their structures before they get to work, already during the activation process. As a result, the reaction is catalysed by a catalyst that is different from the ...
Southern California ozone pollution declining in recent decades
Many studies have documented the decline in ozone pollution and its precursors in the Los Angeles air basin over the past several decades.
Greener milk: How to make cow's nitrogen intake efficient
The amount of nitrogen that is excreted by livestock is directly proportional to the amount it is fed. This is according to Chris Reynolds a researcher in nutritional physiology of ruminants at the University ...
Fertilizer that fizzles in a homemade bomb could save lives around the world
A Sandia engineer who trained U.S. soldiers to avoid improvised explosive devices (IEDs) has developed a fertilizer that helps plants grow but can't detonate a bomb. It's an alternative to ammonium nitrate, ...
Pioneering study calculates Arctic Ocean nutrient budget
The first study of its kind to calculate the amount of nutrients entering and leaving the Arctic Ocean has been carried out by scientists based at the National Oceanography Centre, Southampton.
High rates of nitrogen fixation measured in equatorial upwelling region
Surface waters in upwelling regions of the ocean are generally rich in nutrients. Scientists had thought that these areas would have low rates of nitrogen fixation because diazotrophs-microbes that convert nitrogen gas from ...
Nonnative salmon alter nitrification in Great Lakes tributaries
Nonnative species can affect the biogeochemistry of an ecosystem. For instance, Pacific salmon have been introduced as a sport fishery in many streams and lakes beyond their native range, but their introduction may be altering ...
Ecological research leads to call to control feral pigs
(Phys.org) —University of Auckland research revealing the extent to which feral pigs can disturb forest vegetation and soils has led to a call for the animals to be controlled as a pest in areas of high ecological value.
Tracing nitrate in watersheds
Plants need nitrogen to grow, and nitrate is a common fertilizer ingredient, but high levels of nitrate contamination in drinking water sources can cause health problems. It is generally known that nitrogen flows through ...
Study finds iron from glacial melting serves as significant source of iron to North Atlantic Ocean
Toxic oceans may have delayed spread of complex life
A new model suggests that inhospitable hydrodgen-sulphide rich waters could have delayed the spread of complex life forms in ancient oceans.
