The end of mad cow disease? Scientists announce a filter that can remove the prions that cause vCJD - blocking the spread of the disease, at least via blood transfusions.
That is terrific news, I'm hoping it holds. CJ disease is a terrible, terrible thing.

Good news indeed, not only for prion diseases, but as a potential treatment approach for other diseases involving malformed proteins. Here's hoping this filter becomes commercial for treating all the blood supply.

I always felt sorry for the cow that the UK news broadcasts usually showed, slipping down a ramp covered with shit. Just looked like an accident to me.
Still, I'm helluva glad I stopped eating meat in the 1980s.

Now we can feed the cows more cows again.
Only if we grind them down into liquid slurry and pass them through the filter first. Actually that doesn't sound that implausible for modern agricultural practice.

This is good news.
Recently my girlfriend Dana and I went to dine at Missoula Montana's finest eating establishment, the Oxford. The Oxford's greatest delicacy has always been brains and eggs. Sadly, I was not able to fulfill my gustatory wishes, as they had been unable to obtain the requisite brains for some time now.
It's sad to see sublime traditions pass...

Why are cows still fed other cows? And how often is mad cow acquired through blood transfusions? Wouldn't it be simpler simply to test the blood for Mad Cow before transfusion?

I read 'Mad Cow' as 'McDonald's' for some reason the first time I parsed that sentence.

Cows are no longer fed cows, this for blood from people who may have eaten mad cows some time ago in britain (or who may have the sporadic form, about 6 in a million I think or the familial form)
The second paragraph states that there is no test for blood (concentration is too low). I doubt you would get many blood donors if you required the same test for as for suspect cows (removing the brain).
As a prion researcher, I'm interested in this compound "L13" that binds so specifically to PrP. It would make purification of recombinant prion protein (we have E.coli that produce the protein for us) much easier.

445supermag, the full journal article is available on The Lancet. (Functional BugMeNot reg is 'blackcabbage' for user & pass.) The footnotes (specifically #16) appear link to further detail on the resin(s) chosen to bind to PrP, those links should also be accessible with the BugMeNot reg. Hope that's helpful, or at least provides some added info.

If this works, let's hope Prions are the real cause of this disease!!

Without speaking about the UK, at least in the US, cows aren't fed other cows. If I recall correctly....
Chickens are fed cows, and the cows are fed the chicken shit, which in a lot of cases, contains ground up cows.
Essentially, the methods the US uses to raise cows is just world class jackassery, and they should all take a step back and ask themselves -
"If I do this to the animals, will people think I'm an asshole?"
I think that would save us a lot of grief with the fucked up farming methods used in the states.
