Half a protein is better than none, and in this case, it’s way better than a whole one. A Rice University lab has discovered that dividing a particular fluorescent protein and using it as a tag is handy for analyzing the workings of live cells, particularly in the way they employ iron-sulfur clusters.

An investigation by the University of Kansas’ Adrian Melott and colleagues reveals a promising new method of detecting past comet strikes upon Earth and gauging their frequency
LAWRENCE, Kan. — It’s the stuff of a Hollywood disaster epic: A comet plunges from outer space into the Earth’s atmosphere, splitting the sky with a devastating shock wave [...]

A new study involving data from more than 20,000 individuals has uncovered several DNA sequences linked to impaired pulmonary function. The research, an analysis that combined the results of several smaller studies, provides insight into the mechanisms involved in reaching full lung capacity. The findings may ultimately lead to better understanding [...]

Next time you spy the Big Dipper, keep in mind that there is another star, invisible to the unaided eye, contributing to this constellation. According to a new paper published in The Astrophysical Journal, one of the stars that makes the bend in the ladle’s handle, Alcor, has a smaller red dwarf companion.

Contrary to preconceived notions, the atmosphere and the oceans were perhaps not formed from vapors emitted during intense volcanism at the dawning of our planet. Francis Albarède of the Laboratoire des Sciences de la Terre (CNRS / ENS Lyon / Université Claude Bernard) suggests that water was not part of the Earth’s initial inventory but [...]
