| How To Hunt Like A Neanderthal
|
 Our hominin family tree includes plenty of meat-eaters, going back a couple million years at least — this is not news. But it's one thing to find evidence of animals that were butchered and consumed by our ancestors and closest kin. It's another to figure out how they got their groceries. Deer bones excavated from a site in Germany and dated to 120,000 years ago are the earliest clear evidence of how our evolutionary siblings, the Neanderthals, hunted. To be clear, European excavatio

| Integrasys Achieves Award-Winning Development with ESA Support
|
 Integrasys has successfully worked with the support of the European Space Agency (ESA) to develop an award-winning solution, ALUSAT. The Always Up Satellite Terminals (ALUSAT) solution improves the operation of 2-way satellite networks by enabling maintenance procedures that minimize operational costs caused by service failures. This enhances network availability and end user satisfaction. Integrasys' Alusat VSAT maintenance system screenshot. ALUSAT technology was developed under the ARTES Core Competitiveness (CC) program by Integrasys. The resulting product implements the key functionalities of a Network Management System for Broadband ...

| First space, then auto—now Elon Musk quietly tinkers with education
|
 Enlarge / A glimpse of a SpaceX worker in Hawthorne: young, wearing a hat, possibly listening to music! (credit: SpaceX) In a corner of SpaceX's headquarters in Hawthorne, California, a small, secretive group called Ad Astra is hard at work. These are not the company's usual rocket scientists. At the direction of Elon Musk, they are tackling ambitious projects involving flamethrowers, robots, nuclear politics, and defeating evil AIs. Those at Ad Astra still find time for a quick game of dodgeball at lunch, however, because the average age within this group is just 10 years old. Ad Astra encompasses students, not employees. For the past four years, this experimental non-profit school has been quietly educating Musk's sons, the children of select SpaceX employees, and a few high-achievers from nearby Los Angeles. It started back in 2014, when Musk pulled his five young sons out of one of Los Angeles' most prestigious private schools for gifted children. Hiring one of his sons' teachers, the CEO founded Ad ...

| Russia's Proton rocket, which predates Apollo, will finally stop flying
|
 Enlarge / A Russian Proton rocket launches in 2016. (credit: NASA/ESA) The Russian-manufactured Proton rocket has been flying into space since before humans landed on the Moon. First launched in 1965, the rocket was initially conceived of as a booster to fly two-person crews around the Moon, as the Soviet Union sought to beat NASA into deep space. Indeed, some of its earliest missions launched creatures, including two turtles, to the Moon and back. But now, Russian officials confirm, the Proton rocket will finally reach its end. In an interview with a Russian publication, Roscosmos head Dmitry Rogozin said production of the Proton booster will cease as production shifts to the new Angara booster. (A translation of this article was provided to Ars by Robinson Mitchell, a former US Air Force Airborne Cryptologic Language Analyst). No new Proton contracts are likely to be signed. Presently, Proton rockets are built at the Khrunichev State Research and Production Space Center in Moscow, then they're ...

| The impact of temporal sampling resolution on parameter inference for biological transport models
|
| by Jonathan U. Harrison, Ruth E. Baker Imaging data has become an essential tool to explore key biological questions at various scales, for example the motile behaviour of bacteria or the transport of mRNA, and it has the potential to transform our understanding of important transport mechanisms. Often these imaging studies require us to compare biological species or mutants, and to do this we need to quantitatively characterise their behaviour. Mathematical models offer a quantitative description of a system that enables us to perform this comparison, but to relate mechanistic mathematical models to imaging data, we need to estimate their parameters. In this work we study how collecting data at different temporal resolutions impacts our ability to infer parameters of biological transport models; performing exact inference for simple velocity jump process models in a Bayesian framework. The question of how best to choose the frequency with which data is collected is prominent in a host of studies because ...
