Superconductivity is the phenomenon by which, at sufficiently low temperatures, electric current can flow in a metal with no resistance. While certain metals are excellent superconductors, other metals cannot superconduct at all.

From time to time, when Earth’s tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar Müller and colleagues show how this gas released from deep Earth may have affected the climate over the past billion years.
Mirroring the mechanisms that make human faces and bodies—and those of many multicellular organisms—symmetrical, bee colonies build symmetrical nests when they are placed on either side of a double-sided comb. The finding, published in Current Biology, extends examples of symmetry in biology to the behavior of communities and the architectural structures that they build.
Boston Children’s Hospital and Harvard Medical School researchers have discovered a neuroimmune communication pathway that may drive endometriosis-associated pain and lesion growth.
Endometriosis is a debilitating inflammatory disease affecting up to 15% of women and is characterized by the growth of endometrial-like tissue outside the uterus. Treatments can currently only target symptoms, with over-the-counter pain medicines and hormonal birth control, or in some cases, surgery.
Endometriosis occurs when cell tissues normally found within the uterus lining take root in areas outside the uterus. This tissue is hormonally sensitive and can become inflamed, especially during menstrual cycles, and can cause severe cramping, pain, and other symptoms depending on the area affected.

The approach mitigates risk and enables easy adoption. The RAD510 computer board will launch in industry-standard 3U form factor and use software compatible with the BAE Systems RAD750 and RAD5545 computer boards.
The RAD510 embedded computing board is for the challenging environment of radiation and extreme temperatures of space. It is built on the BAE Systems RAD750 computer board that has enabled more than 100 satellites.
SAN DIEGO – U.S. Navy electronics experts are hiring two companies to develop enabling technologies to safeguard naval systems from the effects of high-altitude electromagnetic pulse (EMP).
Officials of the Naval Information Warfare Center Pacific in San Diego, announced estimated $12.5 million separate contracts Wednesday to Long Wave Inc. in Oklahoma City, Okla., and to Reliance Construction Co. in Cary, N.C., for high-altitude EMP hardening processes.
