The graphite found in your favorite pencil could have instead been the diamond your mother always wears. What made the difference? Researchers are finding out.

How molten carbon crystallizes into either graphite or diamond is relevant to planetary science, materials manufacturing and nuclear fusion research. However, this moment of crystallization is difficult to study experimentally because it happens very rapidly and under extreme conditions.

The Earth formed relatively quickly from the cloud of dust and gas around the sun, trapping water and gases in the planet鈥檚 mantle, according to research published Dec. 5 in the journal Nature. Apart from settling Earth鈥檚 origins, the work could help in identifying extrasolar systems that could support habitable planets.

First Jellyfish Genome Reveals Ancient Beginnings of Complex Body Plan

Jellyfish undergo an amazing metamorphosis, from tiny polyps growing on the seafloor to swimming medusae with stinging tentacles. This shape-shifting has served them well, shepherding jellyfish through more than 500 million years of mass extinctions on Earth.

鈥淲hatever they鈥檙e doing has really worked for them,鈥� said David Gold, an assistant professor of paleobiology in the University of California, 海角原创, College of Letters and Science.

Volcanic Crystals Give a New View of Magma

Volcanologists are gaining a new understanding of what鈥檚 going on inside the magma reservoir that lies below an active volcano, and they鈥檙e finding a colder, more solid place than previously thought, according to new research published June 16 in the journal Science. It鈥檚 a new view of how volcanoes work, and could eventually help volcanologists get a better idea of when a volcano poses the most risk.
