conflicting results for the natural decay of the neutron that depend upon the type of experiment used, with discrete lifetimes of 887.7 seconds and 878.5 seconds from two different methods lying outside experimental error and that may point to new physics not yet understood.

Wednesday, March 26, 2014
most distant known object in our solar system, part of the inner Oort cloud with an elliptical orbit of 80 AU at its closest point to the Sun and perturbed enough to suggest the existence of a further large, planet-sized massive body.

chimeric albino redwood growing near a railroad in Cotati, California, one of only ten specimens ever found that produce male and female cones as well as displaying normal and albino tissues in the same tree.
Wednesday, March 19, 2014
persistent pattern in the inner radiation belt surrounding Earth similar to "zebra stripes," a distortion caused by the rotation of the planet that was previously thought incapable of affecting the high-energy electrons of the belts with velocities near the speed of light.
