Bavarian beer purveyors concerned about a smelly Oktoberfest are hoping bacteria can make the experience more enjoyable. They plan to pour a solution of live bacteria on the floors of Munich's beer tents, in an effort to knock out the inevitable festival smells usually covered up by a fog of cigarette smoke.
If something doesn't smell right, the Army wants to know about it. But while the Pentagon has been angling for a biosensors that can smell fear or nervousness in a person's bodily emanations for some years now, the Army wants something more: The ability to "uniquely identify an individual based on scent" from a distance or even days after the person has left the scene.
Usually the enticing smell of food is associated with hunger pangs, but researchers in the Netherlands think that foods can be engineered to release satiating aromas during chewing. This would help combat obesity by stimulating areas of the brain that signal fullness.
Researchers are now profiling the chemicals released from decaying bodies, in an effort to create a sensor that might be able to sniff out corpses in the rubble, or determine a dearly departed's precise time of death.

For scientists, having to retract a paper is like a kick to the gut. It means that your work cannot be verified, and thus is likely either 1) an error or 2) a fabrication. So it comes as something of a surprise that Nobel prize-winning scientist Linda B. Buck had to retract a 2001 Nature paper this week, citing an inability to reproduce the reported findings, and "inconsistencies between some of the figures and data published in the paper and the original data."
