    Physicists have proposed that violations of energy conservation in the early universe, as predicted by certain modified theories of quantum mechanics and quantum gravity, may explain the cosmological constant problem, which is sometimes referred to as “the worst theoretical prediction in the history of physics.” “The main achievement of the work was the unexpected relation between two apparently very distinct issues, namely the accelerated expansion of the universe and microscopic physics,” Josset said.

    Nanoparticles and Faraday rotation allow faster diagnoses. A UCF researcher has combined cutting-edge nanoscience with a magnetic phenomenon discovered more than 170 years ago to create a method for speedy medical tests. The discovery, if commercialized, could lead to faster test results for HIV, Lyme disease, syphilis, rotavirus and other infectious conditions. “I see no reason why a variation of this technique couldn’t be in every hospital throughout the world,” said Shawn Putnam, an assistant professor in the University of Central Florida’s College of Engineering & Computer Science.

    Researchers have demonstrated the first important step toward integrating atomically precise graphene nanoribbons (APGNRs) onto nonmetallic substrates. Silicon crystals are the semiconductors most commonly used to make transistors, which are critical electronic components used to carry out logic operations in computing. However, as faster and more powerful processors are created, silicon has reached a performance limit: the faster it conducts electricity, the hotter it gets, leading to overheating.

    Graphene, made of a single-atom-thick sheet of carbon, stays much cooler a...
