Assorted news

I was just pondering the appalling lack of interesting science news the other day, and then I got back home and found these: CSI Ambleside...

The DAMA collaboration is claiming strong evidence for WIMPy Cold Dark Matter, based on an annual modulation in their scintillator experiment.

Ah, I was wondering why Stanford had a non-detection by their CDM detector group as a lead news item last week.

Sean has rounded up a guest blogger to explain this result, or lack thereof.

There is a new class of high critical temperature superconductors.
Non-cuprates, based on FeAs - that is iron/arsenic for those with a limited perspective on the periodic table (man, those physicists do some complicated chemistry - why so many metals?).
h/t Incoherent Ponderer, but the real info is over at nanoscale views with updates here and here.
And the discovery paper

I am also bemused by the linear optical absorbitvity of graphene sheets - 0.023 opacity doesn't sound like much, but that is per sheet.
Atom thick sheet.

Now contemplate 0.977n in the limit of moderately large n.
Consider, for example a sheet of graphene only 1000 atoms thick.
If this holds, that is absorptivity of 0.99999999992 or so, across the relevant band.
That could be useful.

But, the real news is: CSI: Ambleside by Half Man, Half Biscuit is coming out next week.

The third song, "Bad Losers on Yahoo Chess"argh "Blue Badge Abuser"... is from the new album.

The DAMA collaboration, an experimental team searching for dark matter via direct detection, is poised to report this week that they have discovered Dark Matter. And I'm here to pre-empt that by bringing you the truth: no, they haven't. They take some very cold (cryogenic) atoms, look for nuclear…
