Astronomers’ industrial espionage

https://www.mpg.de/17471408/astronomers-industrial-espionage

Using radio data from the ALMA observatory and physical modelling, astronomers led by Kamber Schwarz (Max Planck Institute for Astronomy and University of Arizona) have managed to determine the mass of a potential “planet factory,” the protoplanetary disk around the star GM Aurigae. From their reconstruction, which includes a determination of the disk’s temperature profile, the astronomers deduce that the factory may just have started production: in an unstable region, conditions should be right to form a giant gas planet. The results showcase the increasing ability of astronomers to probe physical properties of planet formation as it happens.
Their reference point was an (axisymmetric) physical model they had created for the

Surviving amongst cannibals

Beyond a certain population density, locusts form swarms with collective movement to keep the risk of cannibalism as low as possible. This is also the reason why the change in movement patterns developed at all in the course of evolution. The behavioural change from solitary individuals to gregarious individuals, called polyphenism, ensures the population’s survival. This discovery was made by scientists from the Max Planck Institute for the Physics of Complex Systems, working in an international research team, using a computer simulation. Moreover, according to the findings, the threshold value at which the swarm disperses again is considerably lower than at swarm formation. This is important for the prevention of locust plagues, in which the insects destroy entire harvests and cause great devastation.
The scientists designed a computer model that simulates the movement of the locusts
