In the course of their life, open star clusters continuously lose stars to their surroundings. The resulting swath of tidal tails provides a glimpse into the evolution and dissolution of a star cluster. Thus far only tidal tails of massive globular clusters and dwarf galaxies have been discovered in the Milky Way system. In open clusters, this phenomenon existed only in theory. Researchers have now finally verified the existence of such a tidal tail in the star cluster closest to the Sun, the Hyades. An analysis of measurements from the Gaia satellite led to the discovery.

Astronomers have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion years ago.

Geophysicists used data from an enormous earthquake in Bolivia to find mountains at the base of the mantle's transition zone, located 660 kilometers below our feet. Their statistical model didn't allow for precise height measurements, but these mountains may be bigger than anything on the surface of the Earth. The researchers also examined the top of the transition zone (410 km down) and did not find similar roughness.

Researchers have created an extremely light, very durable ceramic aerogel. The material could be used for applications like insulating spacecraft because it can withstand the intense heat and severe temperature changes that space missions endure.

New therapeutic molecules show promise in reversing the memory loss linked to depression and aging. These molecules not only rapidly improve symptoms, but remarkably, also appear to renew the underlying brain impairments causing memory loss in preclinical models.

Flexible tool use is closely associated to higher mental processes such as the ability to plan actions. Now a group of cognitive biologists and comparative psychologists found out that the apes carefully weighed their options. To do so the apes considered the details such as differences in quality between the two food rewards and the functionality of the available tools in order to obtain a high quality food reward.

One of the most successful and enduring feats of interplanetary exploration, NASA's Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA's return to the Red Planet.
