The digging, stirring and overturning of soil by conventional ploughing in tillage farming is severely damaging earthworm populations around the world, say scientists.

Scottish badgers highlight the complexity of species responses to environmental change
In a new study researchers have found that although warmer weather should benefit badger populations, the predicted human population increase in the Scottish highlands is likely to disturb badgers and counteract that effect. These results emphasise the importance of interactive effects and context-dependent responses when planning conservation management under human-induced rapid environmental change.
NASA Spots Powerful Tropical Cyclone Donna Between Vanuatu and New Caledonia
Tropical Cyclone Donna continues to move through the South Pacific Ocean as a major hurricane. NASA's Aqua satellite passed over the storm and captured an image of a clear eye as the storm was located between the island nations of Vanuatu and New Caledonia. The GPM satellite found that the powerful hurricane was generating very high amounts of rainfall.
Poor overall environmental quality linked to elevated cancer rates
Nationwide, counties with the poorest quality across five domains – air, water, land, the built environment and sociodemographic – had the highest incidence of cancer, according to a new study published in the journal Cancer.
'Hot' electrons don't mind the gap
If they’re quick about it, “hot” electrons excited in a plasmonic metal can tunnel their way across a nanoscale gap to a neighboring metal. Rice University scientists said the cool part is what happens in the gap.
A Rice team discovered those electrons can create a photovoltage about a thousand times larger than what is seen if there is no gap. The finding shows it should be possible to create nanoscale photodetectors that convert light into electricity and can be used as sensors or in other sophisticated electronics.
Space Weather Model Simulates Solar Storms From Nowhere
Our ever-changing sun continuously shoots solar material into space. The grandest such events are massive clouds that erupt from the sun, called coronal mass ejections, or CMEs. These solar storms often come first with some kind of warning — the bright flash of a flare, a burst of heat or a flurry of solar energetic particles. But another kind of storm has puzzled scientists for its lack of typical warning signs: They seem to come from nowhere, and scientists call them stealth CMEs.
