Quebec Physicist Talks Confidently of Reaching Room Temperature Superconductors

by

Physics professor Louis Taillefer’s findings reduce theories explaining high-temperature superconductivity from dozens to only a few. Taillefer, who collaborated with University of British Columbia scientists, published the team’s most recent findings on high-temperature superconductivity in prestigious science journal Nature on Thursday. They explain the “pseudo-gap” phase, when copper oxides are cooled to minus-100C, and the …

Diamond-based nanowire devices advance quantum science at Harvard

by

Illustration by Jay Penni. Researchers used a top-down nanofabrication technique to embed color centers into a variety of machined structures. By creating large device arrays rather than just “one-of-a-kind” designs, the realization of quantum networks and systems, which require the integration and manipulation of many devices in parallel, is more likely. By creating diamond-based nanowire …

Barley as Farmed Fish Feed Could Replace Millions of tons of Wild Fish for Feed

by

Millions of tons of menhaden and other small fish are removed from the oceans each year to feed fish, poultry, and swine. The total amount of fish harvested for fishmeal has not changed in the last 20 years, but the demand has increased sharply. This pressure is thought by some to presage ecological problems and …
