VR system simulates the effects of dementia

It may be an overused proverb, but it's a good one: "Tell me and I will forget. Show me and I will remember. Involve me and I will understand." That's the definitely the thinking behind Virtual Dementia Experience, a virtual reality system created by four multimedia graduates from Australia's Swinburne University. It provides caregivers with an interactive simulation of what it's like to suffer from dementia, so they can better understand what their patients are experiencing.

New software provides an animal-eye view of our colorful world

Have you ever looked at a flower and thought, "I wonder what these colors would look like to a bee"? Perhaps not, but in any case, you can now find out using your own camera and computer. That's because scientists from the University of Exeter have developed the Multispectral Image Calibration and Analysis Toolbox, a piece of free software that lets you see the colors in photos the way that various animals would see them.

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

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

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

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.

Sandia drops nuclear warhead ... in the name of safety

Dropping a nuclear warhead may not seem like a particularly bright idea, but earlier this year Sandia National Laboratories did just that. As part of the US government’s Life Extension Program (LEP) for its nuclear arsenal, the inert W88 ALT 370 warhead was dropped from a crane in New Mexico onto a slab of concrete to test the updated design’s safety.

Impressions: Assetto Corsa with the Oculus Rift DK2

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

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.
