Workers make around 13% more sales in weeks where they report being happy compared to weeks when they are unhappy, according to a study by researchers from the United Kingdom, the United States, and the Netherlands. Bellet et al found a conclusive link between happiness and productivity.

In this diagram of the new system, air entering from top right passes to one of two chambers (the gray rectangular structures) containing battery electrodes that attract carbon dioxide; then the airflow is switched to the other chamber, while the accumulated carbon dioxide in the first chamber is flushed into a separate storage tank (at right); these alternating flows allow for continuous operation of the two-step process.

Stormquakes offshore North America and seismic stations from 2006 to 2015. The located stormquakes are shown as the red circles, and the seismic stations are shown as triangles. Due to the location uncertainties, some of the apparent stormquake locations are beyond the coastlines. The yellow contours show regions where stormquakes were detected. The orange contour shows a comparison region offshore Mexico that has been struck by hurricanes but without excitation of stormquakes. The insert shows earthquakes (blue dots) reported in the International Seismological Centre catalog with magnitudes greater than 3 and shallower than 40 km from 2006 to 2015.

The moons of our Solar System are brimming with unusual landscapes. However, sometimes they look a little more familiar, as in this new radar image from the Cassini orbiter. The image shows dark streaks carved into dunes reminiscent of those we might find on a beach on Earth, or raked with flowing lines in a Japanese Zen garden — but this scene is actually taking place on Saturn’s moon Titan. While our sand is composed of silicates, the ‘sand’ of these alien dunes is formed from grains of organic materials about the same size as particles of our beach sand. The small size and smoothness of these grains means that the flowing lines carved into the dunes show up as dark to the human eye. While previous images have spotted these eerily familiar patterns on Titan's dunes, this new image (colorized) shows them in greater detail. The image was obtained by Cassini's radar mapper on July 10, 2013. The vertical seam near the center is an artifact of radar image data processing. Image credit: NASA / JPL-Caltech / Sci-News.com.

In human skulls, division of the nasioiniac arc (from nasion to inion, NI) by bregma into a shorter frontal arc (from nasion to bregma, NB) and longer parietooccipital arc (from bregma to inion BI), creates a geometrical relationship in which the ratio of the nasioiniac arc over the bregma-inion arc (NI/BI) coincides with the ratio of the bregma-inion arc over the nasion-bregma arc (BI/NB), both 1.6. The subdivision of the nasioiniac arc by bregma into two unequal arcs emulates the geometrical division of a line into the Golden ratio.
