Gloves may head off ‘garden’ variety pneumonia
Compost feels so good, sifting through a gardener’s fingers. Unfortunately, data are showing, this soil amendment can host a germ responsible for Legionnaire’s disease, a potentially serious form of pneumonia.

Tar sands ‘fingerprint’ seen in rivers and snow
A new study refutes a government claim (one echoed by industry) that the gonzo-scale extraction of tar sands in western Canada — and their processing into crude oil — does not substantially pollute the environment.

Academies recommend that IPCC make changes
The Intergovernmental Panel on Climate Change, an authoritative scientific organization set up in 1989 to assess climate science, took some heat today from a group that it commissioned to investigate its credibility. The oversight group reported findings procedural weaknesses that preclude IPCC from responding nimbly to events — or from reliably identifying errors in its assessments.

‘Bug traps’ in Gulf to use BP oil as bait
To assay how appetizing polluting oil is to native Gulf micobes — and how rapidly they degrade it — researchers plan to set 150 “bug traps” on August 26.. Their bait: the same oil that had been spewed for months by BP’s damaged Deepwater Horizon well.

Deep-sea plumes: A rush to judgment?
A new report suggests a deep-sea plume of oil in the Gulf of Mexico has been gobbled up by microbes. But the scientist who described the incident doesn't "know" that. He can't — yet.
