I heard/read that there are few people with very keen sense of smell who are called a Nose who identify scents. Is this true? If so, what type of jobs are for these people? And what it the job title actually called?

FDA considers a ban on cold medicine for children.
If they were going to do this, shouldn't it have happened when they banned phenylpropanolamine?
Though they aren't notably effective, isn't 3 or 4 dead kids a year too few to call them unsafe, especially since most of those are overdoses?
Would this eventually have any impact on the American mindset that there's a drug for every problem?
We know that Dimetapp, for instance, is popular because of its sedative properties, not because of any effect it might have on the cold symptoms. Will mothers substitute for a bottle of milk with a bottle of beer?

Explain

1. What caused all the bright flashes of light?

2. What caused all the horizontal and rapid explosions so far
below the collapsing levels? (and please don't say it was
due to air pressure, because these look like focused point
source explosions, and this cannot possibly be caused by
built up air pressure, since this is not an "air tight" leak-proof
sealed environment, due to all the cracked ceilings and
damaged upper floors) - don't tell me you can inflate & pop
a balloon if the balloon has lots of leaks and holes in it!

3. What caused all the molten metal dripping out of the South
Tower? Melting point of steel = 1532 C, but the hottest
temperature that a jet fuel (kerosene) fire can reach, burning
in still or stationary air (not moving air) is only 250 C. And
don't say this is molten aluminium ( melts at 600 C).
Why do steel or Al frying pans not melt?

I can't decide if this is for real or a joke. The site of the company that's buying the DNA (www.NewLineGenetics.com) looks pretty solid, but if they're telling the truth, it's amazing what they can do.

Can somebody help me with these 2 problems. i need examples.
1. compare the function g(x) = Ix+cI, where c is any real number, with the function f(x) = IxI. Describe the axis of symmetry, the domain and the range of g.
2. compare the function h(x) = x + d, where d is any real number, with the function f(x) = IxI. Describe the axis of symmetry, the domain and the range of g.

the I___I is the absolute value

Topps Meat Co. on Saturday expanded a recall of ground beef from about 300,000 pounds to 21.7 million pounds, one of the largest meat recalls in U.S. history.

THE STORY:
http://www.cnn.com/2007/US/09/29/meat.recall/index.html

MY QUESTION (for the mathematicians out there):
How many cows does 21.7 million pounds of ground beef equate to?

Start here>>how many pounds of ground beef does ONE cow produce?

Give me the number of cows...
>>and how you derived at your answer<<
