For years, researchers believed that Parkinson's disease is caused by the long 'fibrils' found in the neurons of people with Parkinson's disease. Now new computational models show that the real cause may be tiny, oft-overlooked ring structures.

The Einstein@Home volunteer computing project has enabled the public to discover 27 new stars. When someone finds a new pulsar, not only do they enter the history books, they also get a personal email or even a signed-for-letter from project leader Bruce Allen.

Not all computing systems are suited to the same tasks. But which tasks match with which architectures?

Researchers review computer simulations in combination with two decades of observations to get a fix on cloud formation.

The NASA Advanced Supercomputing Division recently released a technical whitepaper that discusses their experiences over the last year using a network flow analysis tool they developed in-house.

By running a sophisticated weather model on supercomputers, environmental engineers have defined optimal placement of a grid of four wind farms off the US East Coast. The model successfully balances production at times of peak demand and significantly reduces costly spikes and zero-power events.

Bug-free code is an impossibility. So, how can researchers know when the bugs in their code are minor, with no real impact, or show-stoppers that completely change the entire result?

As computer chips get smaller and faster, they’re getting hotter and hotter. Typically, almost 40% of a data center’s electricity bill is because of its cooling equipment.

To help reach the exaflop barrier and beyond, some data centers are investing in better cooling than current standard technology. We’ve taken a look at seven promising methods that will help scientific e-infrastructures stay cool.

If the sun is anything, it is reassuring. It rises, sets, and rises again, allowing us to grow crops, get tan, and power homes, just to name a few of humanity’s most important life-sustaining functions. No wonder it was considered a deity by countless ancient civilizations.

Like many other things, however, our sun is prettier at a distance. Turns out the sun is a violent place where magnetic fields and fusion energy spew plumes of radiation into outer space and at Earth. Physicists call this phenomenon space weather, and seek to understand it by running increasingly complex simulations on increasingly powerful computing systems.
