Three Open Access journals move to Springer
Living Reviews are now affiliated to major academic publisher


MPG, June 24, 2015: "Springer has acquired the three pioneering ‘living’ open access journals: Living Reviews in Relativity (impact factor 19.25), Living Reviews in Solar Physics (impact factor 17.64)and the recently launched journal Living Reviews in Computational Astrophysics from the Max Planck Society. Furthermore, Springer has acquired the domain names livingreviews.org and livingreviews.eu, all registered Living Reviews trademarks, as well as the journals’ wordmarks and logos." -- But, who got the bribes and kickbacks?

1.  Introduction
Visual imagery is, for most of us, a conspicuous ingredient of everyday experience, playing a prominent role in memory, daydreaming and creativity. Galton, who pioneered the quantitative study of visual imagery with his famous ‘breakfast-table survey’, reported a wide variation in its subjective vividness  (Galton, 1880). Indeed, some participants described ‘no power of visualising’. This phenomenon has received little attention since, though Faw reported that 2.1-2.7% of 2,500 participants ‘claim no visual imagination’ (Faw, 2009).

The experience of voluntary imagery is associated with activity in fronto-parietal ‘executive’ systems and in posterior brain regions which together enable us to generate images on the basis of our stored knowledge of appearances  (Bartolomeo, 2008). The relative contributions of lower and higher order visual regions to the experience of visual imagery are debated (Bartolomeo, 2008). Clinical reports suggest the existence of two major types of neurogenic visual imagery impairment: i) visual memory disorders, causing both visual agnosia and imagery loss, and ii) ‘imagery generation’ deficits selectively disabling imagery (Farah, 1984).

The Great Pyramid of Ceres.

("Scientists estimate that this structure rises about 3 miles (5 kilometers) above the surface. NASA's Dawn spacecraft took this image from an altitude of 2,700 miles (4,400 kilometers). The image, with a resolution of 1,400 feet (410 meters) per pixel, was taken on June 6, 2015.", NASA, June 22, 2015)

Asteroid Icarus

2929 2a58

Asteroid Icarus will safely pass by Earth at more than 21 times the distance of Earth to the moon on June 16, 2015. To put it another way, Icarus, one of the first near-Earth asteroids ever discovered (1949), will approach no closer than five million miles away (eight million kilometers). On June 14, 2090, the asteroid will approach marginally closer, with a close approach distance of about 17 lunar distances (four million miles, or six-and-a-half million kilometers).

NASA detects, tracks and characterizes asteroids and comets using both ground- and space-based telescopes. Elements of the Near-Earth Object Program, often referred to as "Spaceguard," discover these objects, characterize a subset of them and identify their close approaches to determine if any could be potentially hazardous to our planet. NASA's Near-Earth Object Program is part of the agency's asteroid initiative, which includes sending a robotic spacecraft to capture a boulder from the surface of a near-Earth asteroid and move it into a stable orbit around the moon for exploration by astronauts, all in support of advancing the nation's journey to Mars.
