Whether a material conducts electricity without losses is not least a question of the right temperature. In future it may be possible to make a more reliable prediction for high-temperature superconductors. These materials lose their resistance if they are cooled with liquid nitrogen, which is relatively easy to handle.

Eating about two handfuls of walnuts a day may provide men the added boost they need to improve their fertility, according to a breakthrough study by researchers at the UCLA School of Nursing.

Findings from the study, "Walnuts Improve Semen Quality in Men Consuming a Western-Style Diet: Randomized Control Dietary Intervention Trial," are published Aug. 15 in the "papers in press" section of the peer-reviewed journal Biology of Reproduction.

An investigational drug currently under FDA review for the treatment of rheumatoid arthritis has now shown positive results in patients with moderate-to-severe ulcerative colitis, according to researchers at the University of California San Diego, School of Medicine. The study will appear in the August 16, 2012 issue of the New England Journal of Medicine (NEJM).
