We can post links to or scans of press articles on superconductivity and physics education here.

First off some articles I've collected from Scientific American on superconductivity.

The first one (from 2006) is about superconducting cables, the second one (2007) is about using superconductors in airplane engines, and the third one (2008) is about a new class of superconductors with iron. This is very special since the previous theories and experimental evidence seemed to indicate that the "best conductors" (e.g. iron, copper, silver, gold) could not be superconductors.

However, other metals like mercury and tin are superconductors, so there is no specific rule.

And another. This one is on alternative energy sources using superconductors.

First off some articles I've collected from Scientific American on superconductivity.

And the most recent one, from the August 2009 issue. This one follows up the previous News Scan on Iron pnictide superconductors, and entire new class of high-temperature superconductors to complement the cuprates that were the only ones known to exist so far.

Another very important point about iron (refer to the previous comments below) is that it is also the strongest (?) ferromagnetic substance (ferromagnetism is named after iron). This does not fit very well with superconductors being anti-ferromagnetic or perfect diamagnets, expelling the magnetic field completely.

So a new theory is needed to explain this, and it might help researchers understand more about the nature of cuprate high-temperature superconductors.
