The New York Times: “DNA Buried 7,000 Centuries is Retrieved,” by Nicholas Wade.
Researchers have reconstructed an ancient genome that is 10 times as old as any retrieved so far, and now say that DNA should be recoverable from animals that lived one million years ago. This would greatly extend biologists’ ability to understand the evolutionary past.”
This is a drawing by 11-year old Carl Sagan, everyone. The Library of Congress just recently acquired his personal papers, so we’ll be seeing stuff like this more often.
Also, SPACESHIP REACHES MOON!!!
I think he drew the electron orbits by tracing paperclips.

A uranium glass marble and a rhomb of calcite respectively fluoresce and phosphoresce on a small shortwave (UVC) ultraviolet light. The uranium glass marble exhibits a yellow-green fluorescence. This type of calcite exhibits blue phosphorescence when stimulated with shortwave UV light: it will continue to glow for a few seconds after the UV source is removed.
The marble is about 1.5cm in diameter. Both are transparent under normal light; the calcite is colourless while the marble has a slight yellowish tint.
