I think this is old news? Why is S&T suddenly catching on?

The results were presented this week ...

.... Mumma and his colleagues detected methane at
a level of 250 parts per billion in equatorial
latitudes north of the Hellas impact basin.
Further observations conducted with the 8-meter
Gemini South telescope in Chile also revealed
elevated methane concentrations over Valles
Marineris.

.... These methane concentrations are much higher
than those previously reported. In both locations,
Mumma's group identified two spectral lines due
to methane, which minimizes the possibility of a
false detection.

Preious results were much lower (~35 ppb?) and
only detected by a single line so might have been
a false alarm.

Question: do the MGS and Mars Odyssey imaging systems have the capability to
resolve a cow? I've got a theory, but I'm not ready to discuss it, yet...

Notice the (M)ore in Methane.

Why is S&T suddenly catching on?

Because additional observations have been reported, with higher and more
accurate results?

It's science news. These are science newsgroups.

I look forward to a future where this thread is thousands of entries long, and
people are discussing Hitler's farts.

lol
Cow's fart up Mars? They must be more technically advanced than they put
on!

I same the global map at the GSA a few days ago.
The weird thing is the methane abundance varies systematically with longnitude,
e.g. one side of Mars is gassy and the other side low. This doesnt correspond
with the major geological trends which are latitudnal.

Well the 'life on Mars' theory might cath on
if this proves to be true and is recognised as
a sign of life.
Let's hope this put's some fire under the buts
of the peaple that are still trying to delay a manned
mission to Mars.

Geological? Don't you mean meteorological?
Seems to me the prevailing winds would determine
how the methane was distributes with respect to the point of origin.
