Climate simulations forecast the weather on all seven TRAPPIST exoplanets

Michael Irving November 22, 2018

Among the almost-4,000 exoplanets found so far, none really capture the imagination like TRAPPIST-1. Now a team of astronomers led by the University of Washington has simulated the climates that could be found on each TRAPPIST world.

Rolling stones could be responsible for Phobos' grooves after all

James Holloway November 21, 2018

Scientists have long debated the cause of the distinctive grooves on the surface of Mars' moon Phobos. One leading theory has it that the lines are signs of structural failure. But a competing idea suggests the marks may be superficial, caused simply by rolling stones on Phobos' surface.

Could rolling stones be responsible for the grooves in Phobos' surface?

How dying stars could reignite with help from enigmatic class of black hole

Michael Irving October 31, 2018

A white dwarf is one of the last stages of life for stars of a certain size, and it’s all downhill from there. But supercomputer simulations run by astronomers at LLNL suggest that these dying stars could be reignited by a close encounter with an enigmatic class of black hole.

Simulations suggest that white dwarf stars could be reignited by a close encounter with an intermediate-mass ...

"Nuclear pasta" ranked strongest material in the universe

Michael Irving September 18, 2018

Forget steel, forget diamond and even forget graphene – “nuclear pasta” may be the strongest material in the universe. This strange substance is formed in the intense pressures inside neutron stars, and researchers have now run computer simulations to test just how strong it is.

Ray tracing the focus of Nvidia's new Turing platform and GPUs

Michael Irving August 14, 2018

Nvidia has unveiled its latest GPU architecture, as well as three new chips based on it. Named Turing, the eighth-gen platform is designed with a focus on ray tracing, and the three new GPUs – the Quadro RTX 8000, 6000 and 5000 – are made for professional use in video and simulation.

VR firefighter training simulator keeps Big Data close to its chest

Michael Irving July 31, 2018

Training firefighters can be dangerous, costly and time-consuming. To help train firefighters more often and more easily, a new virtual reality simulator called the FLAIM Trainer has been developed, made up of an HTC Vive VR headset, haptics systems and a vest that tracks the trainee’s vital signs.

Simulations suggest multiverse is either teeming with life – or doesn't exist

Michael Irving May 14, 2018

Our universe seems to contain a suspiciously perfect amount of "dark energy" to sustain life. But new research suggests that life is still possible even with far more dark energy than we have, and the results have some big implications for the multiverse theory.

New simulations suggest life could be more common throughout the multiverse – or perhaps show that ...

Computer-generated fur gets more realistic

Ben Coxworth February 22, 2018

If you're unsatisfied with the realism of computer-generated animals, then you might be interested in the latest news out of the UC San Diego. Working with colleagues from UC Berkeley, scientists there have developed a new method of rendering fur that's much more accurate than existing techniques.

Do gravitational anomalies prove we're not living in a computer simulation?

Michael Irving October 2, 2017

Is our entire universe just a computer simulation? Theoretical physicists believe they’ve found proof that our universe is far too complex to be captured in any simulation. According to the researchers, the hypothesis is done in by gravitational anomalies, tiny “twists” in the fabric of spacetime.

Researchers from Oxford and the Hebrew University believe they've found proof that the universe is too ...
