Fixing a tooth infection may improve blood sugar and heart health - Science Daily

For more than a century, scientists have tried to reconstruct the biology of Tyrannosaurus rex from bones, teeth, footprints, and other traces left behind more than 60 million years ago. Fossils discovered as far north as Alaska have suggested that T. rex could tolerate cold conditions, adding to evidence that the giant dinosaur was moving away from the cold-blooded physiology of many reptiles and toward the warm-blooded metabolism seen in birds. Now scientists have done something that once seemed impossible: they have effectively taken T. rex's temperature.

In April 1991, NASA’s Galileo spacecraft was a year and a half into its journey to Jupiter when it ran the commands to open its main antenna. Minutes later, telemetry showed that the motors had stalled. The 4.8-meter, umbrella-shaped dish had only partly unfolded, and it never fully deployed. Without that antenna, Galileo’s best remaining link to Earth was a small low-gain antenna that could carry only a tiny fraction of the planned data. What followed was one of the more inventive rescues in spaceflight: engineers rewrote the spacecraft’s software to edit and compress its data, rebuilt how Earth listened for it, and replanned the science around a far smaller data budget.
