Maritime scientist in Gulf of Mexico explains controversial decision to inject dispersant chemicals to break up BP's leaking oil / Phone-in: Mary Anne White & Richard Wassersug on the sense of smell and The Science of Everyday Life

Disperse - But How Far ? For several weeks, Maritime scientist Dr Kenneth Lee has been helping monitor attempts to contain and clean up oil leaking from BP's well in the Gulf of Mexico. Dr Lee is with the Centre for Offshore Oil and Gas Environmental Research at the Bedford Institute of Oceanography in Dartmouth, and an expert in chemical oil dispersants. He's been part of the US-led team of scientists monitoring the spill since early May. He explained the rationale behind the controversial use of chemicals to disperse the oil.

The Winner, By A Nose: Oh, sure - you can say you have a scent-free workplace or meeting, but really - do you expect your nose to believe that ? If your neighbour in the next apartment burns the toast or if someone in the elevator is returning from a smoke break outside, your brain gets the message immediately.
But why do we - and so many other organisms - have the sense of smell ? And what about our range of reactions to particular scents - from fear or hunger to lust or nausea ?
Mary Anne White & Richard Wassersug can smell a good topic to kick off their phone-in. Mary Anne is University Research Professor of Chemistry & Physics at Dalhousie University. Richard is Professor of Biology, Anatomy & Neurobiology at Dal, and was in the Melbourne studio of the Australian Broadcasting Corporation today (or, from our time frame, tomorrow). They answered your questions about The Science of Everyday Life.
