Do you want to explore an alien planet? Change your perspective and imagine yourself as the Universe experiencing Earth from the outside. The atoms of your body were created in ancient stars, and have come together to explore one exoplanet among billions.
Hypothetical life reconstruction of Ediacaran organism Rangea.
This illustration is on the cover of the January 2013 issue of the journal Paleontology and although it isn’t credited one of the authors of the paper is the excellent artist Peter Trusler so it is likely to be by him.
These time lapse animations use phase contrast microscopy to show neural stem cells in a nutrient medium for 4 hours. They reveal the dynamic growth and recycling of dendrites and synapses as neurons establish relationships with each other. The social behavior of these cells creates the incredible properties of the mind and brain.
When Greg Dunn finished his Ph.D. in neuroscience at Penn in 2011, he bought himself a sensory deprivation tank as a graduation present. The gift marked a major life transition, from the world of science to a life of meditation and art.
Now a full-time artist living in Philadelphia, Dunn says he was inspired in his grad-student days by the spare beauty of neurons treated with certain stains. The Golgi stain, for example, will turn one or two neurons black against a golden background. ”It has this Zen quality to it that really appealed to me,” Dunn said.
