One Mystery of High-Tc Superconductivity Resolved

11-16-2006 · Brookhaven National Laboratory

Research published online in the journal Science this week by Tonica Valla, a physicist at Brookhaven, appears to resolve one mystery in the 20-year study of high-temperature (high Tc) superconductors -- materials that lose their resistance to the flow of electricity at relatively high temperatures. The research shows that a "pseudogap" in the energy level of the material's electronic spectrum is the result of the electrons being bound into pairs above the so-called transition temperature to the

Teaching mediation skills to parents helps siblings resolve conflicts
05-17-2007 · EurekAlert!
A new study has demonstrated promising results of parents' use of mediation skills to resolve conflicts in children. Half of the parents in a sample of 48 families were trained to use mediation to resolve conflicts with sibling pairs between 5 and 10 years old. Conflicts between siblings were more positively resolved in families that received the mediation training. There were also differences in children’s conflict negotiations depending on whether parents received the mediation training.
