Chemists propose explanation for superconductivity at high temperatures

(PhysOrg.com) -- It has been 25 years since scientists discovered the first high-temperature superconductors—copper oxides, or cuprates, that conduct electricity without a shred of resistance at temperatures much higher than other superconducting metals.

Chemists propose explanation for superconductivity at high temperatures

(PhysOrg.com) -- It has been 25 years since scientists discovered the first high-temperature superconductors—copper oxides, or cuprates, that conduct electricity without a shred of resistance at temperatures much higher than other superconducting metals. Yet no one has managed to explain why these cuprates are able to superconduct at all

Modeling the bizarre: Quantum superfluids

(PhysOrg.com) -- More than 100 years since superconductivity was discovered, a comprehensive description for the behavior of a broad class of fundamental physical systems that exhibit the bizarre properties of superconductivity and superfluidity has been developed.

Return of rare giraffes brings promise of peace among warring Kenyan peoples

It has been 70 years since Rothschild giraffes ( Giraffa camelopardalis rothschildi ), aka Baringo giraffes, disappeared from the Lake Baringo area of Kenya that gave them one of their names. But now eight of these critically endangered animals have returned to the lake, and with them comes an unexpected bonus: a promise of peace. [More]
