Jupiter’s early formation protected Earth

Jupiter’s early formation acted as an effective barrier against inward transport of material across the solar system disk, potentially explaining why our solar system lacks any super-Earths.  Effectivelly protecting the Earth.  Jupiter’s core grew to about 20 Earth masses within 1 million years, then to about 50 Earth masses for 3-4 million years before it’s final 300 EMs.

New form of carbon that’s hard as a rock, yet elastic, like rubber

A team including several Carnegie scientists has developed a form of ultrastrong, lightweight carbon that is also elastic and electrically conductive. A material with such a unique combination of properties could serve a wide variety of applications from aerospace engineering to military armor.
