Planet Earth online is the free, companion website to the award-winning magazine Planet Earth published and funded by the Natural Environment Research Council (NERC). Planet Earth covers news from across the environmental sciences - whether research is funded directly by NERC or is carried out by NERC's research and collaborative centres. It also covers the work of partner organisations, such as through the £1bn "Living with Environmental Change" programme.
New critter discovered on whale carcass
A new species of bug, similar in appearance to the common woodlouse, has been found plastered all over a whale carcass on the floor of the deep Southern Ocean.
Origin of Scandinavian gorges finally revealed
The deep gorges which cut across Scandinavian landscapes may have been carved by rivers flowing under ancient glaciers, say scientists.
Accurate forecasts of Arctic summer sea ice one step closer
Scientists can now forecast how much sea ice will cover the Arctic at the end of the summer by measuring the area covered by ponds of water on the ice in spring.
Breakthrough in understanding swarming potato-blight spores
Scientists have made a breakthrough in understanding how microbial spores, which caused the infamous Irish potato famine are so successful at infecting plants.
Groundwater could fuel life under glaciers
Subglacial lakes in Antarctica might have nutrient-rich groundwater flowing into them, say scientists investigating the origin of the water in ice streams.
Recycling heat from industry could reduce carbon emissions
Industrial processes that require high temperatures often expel any surplus heat into the environment. While industries are fairly good at using as much of this surplus as possible, a small amount of heat is always wasted.
Pumice models could help protect shipping
Scientists have used a computer model of ocean circulation to predict the movement of the rafts of floating pumice given off by an erupting underwater volcano.
India's ancient mammals survived multiple pressures
Most of the mammals that lived in India 200,000 years ago still roam the subcontinent today, in spite of two ice ages, a volcanic super-eruption and the arrival of people, a study reveals.
New model predicts high-speed rail vibrations
Scientists have developed a new model to predict how much a new high-speed railway would shake the ground around it, and the effect this could have on those living near the line.
Cod may serenade females with rhythmic grunts
Male cod may 'sing' to females during mating, suggests a new study investigating the sounds cod and pollack produce during the spawning season.
