Molecular Genealogy in the Arctic Sediment

Heat-loving bacteria found in the Arctic seabed have their origins in oil springs and the depths of the Earth's crust. This is the finding of a project supported by the Austrian Science Fund FWF, which used molecular biology to study "misplaced" bacteria such as these. The possibility that molec... Read More

Contaminated water a concern in Haiti

Haiti’s next survival challenge lurks in its broken pipes, tainted wells and stagnant puddles: Water. If contaminated, it will spread disease. If stagnant, it will breed malarial mosquitoes. And if there’s no water at all, dehydration and death may follow.

Distillery plans to cut costs with bacteria-eating 'digesters'

Sludge from a distillery on Islay is set to be turned into green energy to power whisky production on the island.
Bruichladdich will next month install two anaerobic digesters – in which bacteria eat yeasty waste to produce methane – at a cost of about £300,000.

The methane gas will then be ... Read More
