Leiden astronomers find building blocks for life in the darkest spots of star-forming cloud
An international team led by Leiden astronomers has discovered diverse ices in the darkest, coldest regions of a molecular cloud. To do so, they used the James Webb Space Telescope. This discovery allows astronomers to examine the simple icy molecules that will be incorporated into future exoplanets,…

How do you recognise the atmosphere of extraterrestrial lava worlds?
In the past 30 years, over 5,000 planets have been discovered outside our solar system. One common exoplanet is the lava world, a hot super-Earth with oceans of liquid lava. Mantas Zilinskas developed models to simulate possible atmospheres of these. Those simulations provide guidance for astronomers…

Increased alertness and moderate ingroup cohesion in bonobos’ response to outgroup cues
In the face of threats from other groups, humans, chimpanzees, and a selection of other species get closer with their own. This research shows that even bonobos show a moderated version of this effect. This suggests that this behavior may emerged prior to the Pan-Homo split, several millions years ago.…

Who Owns the Hills? Ownership, Inequality, and Communal Sharing in the Borderlands of India
In his historical analysis of upland societies of the Zomia massif, James Scott (2009) emphasizes how the modern state strives to control and “make taxable” all of its subjects.
