New Seadragon Species Found

Scientists have identified a previously unknown third distinct species of the exotic seadragon, named the ruby seadragon (Phyllopteryx dewysea) after its unusual bright red coloration, while analyzing DNA from tissue samples believed to be from the two known species, the leafy and common seadragons.

Earth's Inner Inner Core

Reading seismic waves that resonate in the aftermath of an earthquake, seismologists have discovered the dense, inner core at the center of the Earth has itself a distinct inner core of about half the diameter, both cores composed of iron crystals but with different and unique properties, possibly different crystalline phases.

No Evolution for 2 Billion Years

Scientists examining microfossils of deep-sea sulfur bacteria from Western Australia's coast found them virtually indistinguishable from those in older samples and the same sulfur bacteria today, an example of more than 2 billion years of no evolution in a static environment that confirms rather than challenges current evolutionary theory.
