Mammography Usefulness Does Not Change At Age 50

Researchers analyzed data from over 72,000 screening mammograms to show a steady increase in cancer detection across all ages, with no abrupt jump at 50. The study challenges previous conclusions that suggested an age-related change in mammography's effectiveness, supporting the continued use of screening for women aged 40-49.

Sapphire Semiconductors? Gem-Like Material May Promise Faster, Smaller, More Reliable Circuits, UD Prof Says

Researchers at the University of Delaware developed a new technique to produce extremely thin alumina films with an electrical storage capacity three times greater than silicon dioxide. These films could potentially eliminate reliability problems in semiconducting circuits by storing more electricity and reducing current-blocking flaws.
