Engineers at MIT and Caltech have demonstrated an ingestible sensor whose location can be monitored as it moves through the digestive tract, an advance that could help doctors more easily diagnose gastrointestinal motility disorders such as constipation, gastroesophageal reflux disease, and gastroparesis.

Communities of microbes that work together release more carbon dioxide than competitive communities, contributing more to climate change.

Humans are artificially expanding cities’ coastlines by extending industrial ports and creating luxury residential waterfronts. 

Climate change is a global environmental concern. A major contribution to climate change comes from excessive burning of fossil fuels.

In the wake of a series of destructive storms in late December and early January, California’s long-ailing mountain reservoirs have risen, satellite images from NASA show.

Santa Barbara Channel’s natural oil seeps are a beach-goer’s bane, flecking the shores with blobs of tar. But the leaking petroleum also creates fascinating geologic and biologic features.

A new study comparing 46 field experiments in 17 countries across four continents clearly spells it out: areas in need of nature restoration benefit from soil transplantation.

Researchers have found that the movement of glaciers in Greenland is more complex than previously thought, with deformation in regions of warmer ice containing small amounts of water accounting for motion that had often been assumed to be caused by sliding where the ice meets the bedrock beneath.

Researchers have calculated the carbon footprint for the full life cycle of fertilisers, which are responsible for approximately five percent of total greenhouse gas emissions – the first time this has been accurately quantified – and found that carbon emissions could be reduced to one-fifth of current levels by 2050.

In the 1970s, Nepal was facing an environmental crisis.
