Astronomers Pin Down Galaxy Collision Rate
A new analysis of Hubble surveys, combined with simulations of galaxy interactions, reveals that the merger rate of galaxies over the last 8 billion to 9 billion years falls between the previous estimates. The galaxy merger rate is one of the fundamental measures of galaxy evolution, yielding clues to how galaxies bulked up over time […]
Transistors are made from natural cotton fibers
October 27, 2011
Smarter, more functional clothing incorporating electronics may be possible in the near future, according to a study co-authored by Cornell fiber scientist Juan Hinestroza. Hinestroza, associate professor of fiber science, was part of an international team that developed transistors using natural cotton fibers. “Creating transistors from cotton fibers brings a new perspective to the seamless […]
Nanotube springs make skin-like sensor
October 27, 2011
Researchers at Stanford University in the US have discovered a type of highly elastic, transparent thin film that conducts electricity extremely well. The film is made of wavy, spring-like carbon nanotubes and could be used as the electrode material in “skin-like” pressure and stretch sensors. Such devices might one day be used to help restore […]
Conceptual Problems in Cosmology
October 27, 2011
F. J. Amaral Vieira In this essay a critical review of present conceptual problems in current cosmology is provided from a more philosophical point of view. In essence, a digression on how could philosophy help cosmologists in what is strictly their fundamental endeavor is presented. We start by recalling some examples of enduring confrontations among […]
