New World Monkeys Are World’s Finest Yodelers, Study Says

New World monkeys, whose range stretches from Mexico to Argentina, were found to have evolved the largest vocal membranes of all the primates, suggesting these thin ribbons of tissue play a particularly important role in their vocal production and repertoire of calls.

Apes and monkeys possess special anatomical structures in their throats called vocal membranes, which disappeared from humans through evolution to allow for more stable speech. However, the exact benefit these provide to non-human primates had previously been unclear. New research provides significant new insights into the diverse vocal sounds of non-human primates, and reveals for the first time how certain calls are produced. New World monkeys,...

The image columns show the change of Uranus for the four years that Hubble’s STIS instrument observed Uranus across a 20-year period. Over that span of time, astronomers watched the seasons of Uranus as the south polar region (left) darkened going into winter shadow while the north polar region (right) brightened as it began to come into a more direct view as northern summer approaches. The top row, in visible light, shows how the color of Uranus appears to the human eye as seen through even an amateur telescope. In the second row, the false-color image of the planet is assembled from visible and near-infrared light observations. The color and brightness correspond to the amounts of methane and aerosols. Both of these quantities could not be distinguished before STIS was first aimed at Uranus in 2002. Generally, green areas indicate less methane than blue areas, and red areas show no methane. The red areas are at the limb, where the stratosphere of Uranus is almost completely devoid of methane. The two bottom rows show the latitude structure of aerosols and methane inferred from 1,000 different wavelengths (colors) from visible to near infrared. In the third row, bright areas indicate cloudier conditions, while the dark areas represent clearer conditions. In the fourth row, bright areas indicate depleted methane, while dark areas show the full amount of methane. At middle and low latitudes, aerosols and methane depletion have their own latitudinal structure that mostly did not change much over the two decades of observation. However, in the polar regions, aerosols and methane depletion behave very differently. In the third row, the aerosols near the north pole display a dramatic increase, showing up as very dark during early northern spring, turning very bright in recent years. Aerosols also seem to disappear at the left limb as the solar radiation disappeared. This is evidence that solar radiation changes the aerosol haze in the atmosphere of Uranus. On the other hand, methane depletion seems to stay quite high in both polar regions throughout the observing period. Image credit: NASA / ESA / Erich Karkoschka, LPL.

This Hubble image shows NGC 4941, a spiral galaxy some 67 million light-years away in the constellation of Virgo. The color image is composed of near-infrared, optical and ultraviolet observations from Hubble’s Wide Field Camera 3 (WFC3). Six filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / D. Thilker.
