An article published in the journal “Computational Astrophysics and Cosmology” presents the complete public release of the simulations coded as TNG100 and TNG300 of the IllustrisTNG project, a highly sophisticated simulation of the universe that has been improved over years of work. A team of researchers kept on improving its details and functionalities also by developing new interaction and exploration 2D and 3D tools to simulate two cubes of space of 100 and 300 million parsec side length.

Deep learning used to map storms on the planet Saturn

An article published in the journal “Nature Astronomy” reports the application of a deep learning algorithm to recognize storms on the planet Saturn creating a map of their components and characteristics. Ingo Waldmann of the University College London, England, and Caitlin Griffith of the University of Arizona, USA, developed the algorithm called PlanetNet based on the TensorFlow “engine” to analyze data collected by the Cassini space probe with an efficiency higher than traditional techniques thanks to the recognition of recurrent characteristics across various multiple data sets. PlanetNet could be adapted to analyze observations of other planets.

Neural networks to predict the mass of planets in formation

An article published in the journal “Astronomy and Astrophysics” shows an example of the use of a neural network and a deep learning algorithm to reduce the time to create simulations of star systems formation obtaining even better results. Yann Alibert of NCCR PlanetS and of the Swiss University of Bern and Julia Venturini of the International Space Science Institute (ISSI) of Bern and a PlanetS collaborator developed this new system that predicts the mass of a planet starting from the conditions in which it formed with a excellent accuracy and a much higher speed than models based on differential equations.

A California district court has approved a settlement between the PC manufacturer Lenovo and a group of customers to wrap up a class action that began after an adware that caused a serious vulnerability had been discovered on various Lenovo laptop models. The laptop maker will pay a total of $7.3 million while Superfish, the producer of the adware, will pay another million dollars to close the litigation for good.

Jim Whitehurst in 2010

IBM and Red Hat announced that they have reached an agreement with which IBM will acquire all Red Hat’s shares, whose value closed last Friday at $116.68, for $190 per share paid in cash for a total value of about $34 billions. Red Hat will become part of IBM’s Hybrid Cloud division while its CEO Jim Whitehurst will join IBM’s senior management reporting to CEO Ginni Rometty. This acquisition is oriented above all to make IBM a giant in the field of cloud services.
