Happy and Healthy New Year 2019!December 2018 was full of events, like partially closing the U.S. government, but also good events: Oregon State University engineers are using 3D animations techniques to increase the precision of radiation therapy for prostate cancer, so that neighboring healthy tissues and organs are not affected; Amazon is testing its cashier-less checkout technology for bigger stores, sources tell the WSJ; a successful rocket launch on Monday, 3 Dec, by SpaceX marked twin milestones for the company's drive to ease access for commercial satellites into orbit - the mission was SpaceX's 19th launch this year, topping its previous record of 18 in 2017; the Falcon 9 rocket also carried the largest number of satellites - a cluster of more than five dozen - ever stacked on top a U.S. booster.In this 2nd newsletter of the third volume, the 26th in total, we included the most relevant news, in a balanced approach, usually directly from the source, to help the general public better understand the realities around us. We included also several nice photos - I thank my wife for her photo assistance. Being well and correctly informed is a sine qua non requirement for everybody, in order to make the right decisions for the future.Enjoy this newsletter and be optimist!
