Superager Brains Shrink More Slowly Than Peers’ Brains.

In the April 2017 issue of the Journal of the American Medical Association, an article entitled “Rates of Cortical Atrophy in Adults 80 Years and Older With Superior vs Average Episodic Memory” by Amanda H. Cook, Jaiahre Sridhar, Daniel Ohm, et al., from Northwestern University, Chicago, Illinois, was published. The Paper’s Abstract described the research as follows: “SuperAgers” have previously been defined as adults 80 years and older with episodic memory ability at least as good as that of average middle-age adults. They have a significantly thicker brain cortex than their same-age peers with average-for-age memory, which is unusual as age-related cortical atrophy is considered “normal” and often associated with cognitive decline in non-demented older adults. SuperAgers may experience similar atrophy rates as their cognitively average peers, but start with larger brain volumes, or they may resist age-related cortical atrophy. To examine the latter possibility, we quantitated rates of cortical volume change over 18 months in SuperAgers and cognitively average elderly adults.”

Vela Supernova Remnant.
Credit & Copyright: Marco Lorenzi (Star Echoes). At the northwestern edge of the constellation Vela (the Sails), the four frame mosaic is over 10 degrees wide, centred on the glowing filaments of the Vela Supernova Remnant, the expanding debris cloud from the death explosion of a massive star. Light from the supernova explosion that created the Vela remnant reached Earth about 11,000 years ago. In addition to the shocked filaments of glowing gas, the cosmic catastrophe also left behind an incredibly dense, rotating stellar core, the Vela Pulsar. Some 800 light-years distant, the Vela remnant is likely embedded in a larger and older supernova remnant, the Gum Nebula.

Sunflowers (Tournesols) is the name of two series of still life paintings by the Dutch painter Vincent van Gogh. The first series, executed in Paris in 1887, depicts the flowers lying on the ground, while the second set, executed a year later in Arles, shows a bouquet of sunflowers in a vase. In the artist's mind, both sets were linked by the name of his friend Paul Gauguin, who acquired two of the Paris versions. On March 30, 1987, Japanese insurance magnate, Yasuo Goto, paid the equivalent of US $39,921,750 for van Gogh's Still Life: Vase with Fifteen Sunflowers at auction at Christie's London. The painting currently resides at Seiji Togo Yasuda Memorial Museum of Modern Art in Tokyo.
