MIT study redefines the role of meteorites in the formation of the early solar system

By - January 26, 2015 1 Picture
Until now, it has been generally accepted that a meteor constitutes a time capsule – a relic of the early creation of the solar system that has fallen to Earth, allowing us to delve into the distant past by looking at the composition of the essentially unchanged material that formed the basis of planetary formation. However, a new study carried out by researchers from MIT and Purdue University seeks to challenge the established belief, asserting that rather than representing the kernel of planetary creation, that they are instead a by-product of the violent and often cataclysmic process.

Study finds early warning signals of global ocean conveyor belt collapse

By - December 9, 2014 1 Picture
We could see early warning signs of the collapse of a key component of the global climate up to 250 years in advance, a new study has shown – ample time to either prevent or prepare for the consequences of abrupt climate change. The University of Exeter study analyzed the Atlantic Meridional Overturning Circulation (AMOC), sometimes referred to as the global ocean conveyor belt, in a highly-complex and realistic simulation model, and identified the likely mechanisms that would drive such a collapse.

Latest supercomputers run truer simulations of extreme weather

By - November 12, 2014 1 Picture
High-resolution simulations of the global climate can now perform much closer to actual observations, and they perform far better at reproducing extreme weather events, a new Berkeley Lab study has found. Lead author Michael Wehner heralds this news as evidence of a golden age in climate modeling, as not only did the simulation closer match reality but it also took a fraction as long to complete as it would have in recent history – just three months compared to several years.

Impressions: Assetto Corsa with the Oculus Rift DK2

By - October 16, 2014 1 Picture
With the release candidate of Assetto Corsa available on Steam Early Access, DK2 support heading to iRacing in the next week or two, and Project Cars (again with DK2 support) due in late November, Christmas is arriving early for sim racers. Read on for our impressions of Assetto Corsa with the Oculus Rift DK2 after putting in a few laps of Circuit de Spa-Francorchamps in the P4/5 Competizione. Read More

LLNL improving the efficiency of 3D metal printing

By - June 18, 2014 2 Pictures
To paraphrase Samuel Johnson, there was a time when 3D metal printing was like a dog walking on his hind legs – it wasn't done well; but you were surprised to find it done at all. Now that laser sintering or Selective Laser Melting (SLM) is used for everything from printing rocket engine components to semi-automatic pistols, the time for surprise may b long past, but the technology still has plenty of room for improvement. That's why researchers at the Lawrence Livermore National Laboratory (LLNL) are working on simulations to improve the speed of 3D laser printing and the quality of the final product by using higher-powered lasers.

Illustris computer simulation creates the first realistic virtual universe

By - May 7, 2014 3 Pictures
As you might expect, the scale and complexities of the underlying physics means creating a realistic virtual universe would require some hefty computing power. A team of astronomers is claiming to have achieved this impressive feat using a computer simulation called "Illustris," which took five years to program and, for the first time, can recreate the evolution of the Universe in high fidelity.

US Army examining next-gen augmented reality "live synthetic" simulations

By - April 1, 2014 1 Picture
Modern warfare is sometimes compared to a video game, but within ten years combat training may become the most realistic video game imaginable. The US Army’s Future Holistic Training Environment Live Synthetic program is a new approach to combat training that integrates various simulations into a single, remotely accessible system. Used on bases across the country, its goal is to provide the Pentagon with a cheaper, more effective way of training soldiers for future military operations. Read More

Computer simulation casts new light on the ancient Roman Campus Martius mystery

By - April 1, 2014 2 Pictures
Campus Martius, also known as the Campus of Mars, was built by the Roman Senate just outside the ancient Rome city walls back in 9 BCE. It was built to celebrate the peace brought upon the Roman people as a result of Emperor Agustus’s military conquests. Thanks to a complex computer simulation created by the Institute for Digital Intermedia Arts (IDIA) for Indiana University's School of Informatics and Computing, it is now possible to verify if and how solar alignments influenced the positioning of the different objects on site.
