Brett Smith for redOrbit.com - Your Universe Online In the fluid and somewhat amorphous would of food supply chains, it can be difficult to trace a source of contamination in the event of a pathogen outbreak. A new analysis developed by the Sandia National Laboratories´ National Infrastructure Simulation and Analysis Center (NISAC) could make this vital detective work much more accurate and efficient. According to the center´s report published in the International Journal...

Researchers have discovered a new way in which computers based on quantum physics could beat the performance of classical computers. The work, by researchers based in Singapore and the UK, implies that a Matrix-like simulation of reality would require less memory on a quantum computer than on a classical computer. It also hints at a way to investigate whether a deeper theory lies beneath quantum theory. The finding emerges from fundamental consideration of how much information is needed to...

Model shows that signal clarity only improves if specific energy conditions are met Scientists have shown the energy conditions, under which a weak signal supplied to a physical system emerges as a stronger signal at the output thanks to the presence of random noise (a process known as stochastic resonance), in a paper that has just been published in EPJ B´. Stochastic resonance goes against the intuitive idea that where noise is present, the signal tends to fade. It occurs in...

White noise improves memory in schoolchildren Playing white noise in class can help inattentive children learn. Researchers writing in BioMed Central's open access journal Behavioral and Brain Functions tested the effect of the meaningless random noise on a group of 51 schoolchildren, finding that although it hindered the ability of those who normally pay attention, it improved the memory of those that had difficulties in paying attention. Göran Söderlund from Stockholm University,...

Members of a Syracuse University research team have shown that an obscure phenomenon called stochastic resonance (SR) can improve the clarity of signals in systems such as radar, sonar and even radiography, used in medical clinics to detect signs of breast cancer. It does this by adding carefully selected noise to the system. The result has been a distinct improvement in the system's ability to correctly identify precancerous lesions, plus a 36 percent reduction in false positives. The...

Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
