An international group of astronomers began the Panchromatic Hubble Andromeda Treasury (PHAT) in 2011 to map and study the millions of stars that comprise the Andromeda galaxy. The project has captured the most detailed panoramic images of the galaxy yet seen, revealing that star formation appears to be the same across the universe.

The wizards, er, researchers at the Massachusetts Institute of Technology (MIT) have created a self-folding robot about the size of a US penny. The robot can fold itself like an origami swan, and then move about, executing tasks under the influence of a magnetic field.

At first a printable plastic sheet, it becomes a robot when heated and a small magnet is placed on its back. Thus activated, the robot moves via an interaction between the magnet and external, programmable actuation.

Forecasting the extent of climate change must include social factors, researchers now say. Combining climate change with population growth and using 11 different computational simulations leads scientists to forecast a possible six-fold increase in extreme heat for residents of the southern US by 2070.

Musical collaboration over the internet has been perennially plagued by delay and bad audio; co-performances have been largely a product of smoke and mirrors.

Overcoming the problems of distance, Internet2 and LoLa technology have set a new standard in video conferencing, allowing broader access to high-level musical and educational opportunities.

A wheeling Milky Way or dancing aurora borealis inspires awe and broadens perspective when viewed across the chronological scales time-lapse videos afford. The trouble is it takes a lot of time to construct these videos. But in the smartphone age, the power of collected photographs enables a more collaborative method.

Ethnic identification is fraught with difficulty, but political scientist Andy Harris has trained a supercomputer to extract group ethnicity from voter rosters in order to address social problems.

Turns out a list of names can tell you a lot about people — if you know how to look.

When politicians can't agree on spending priorities and decide to shut down the government, federal functions come to a grinding halt. In the US, this scenario has repeated a dozen times since the Reagan era; Eric Svensen looked to a supercomputer to find out why.

Over 100 people converged to assemble Purdue University’s latest research supercomputer, Rice — in a single day!

On Friday, 8 May, staff and volunteers built a new cluster of 576 HP compute nodes with two 10-core Intel Xeon-E5 processors (20 cores per node) and 64 GB of memory. The cluster features a Mellanox 56 GB FDR Infiniband interconnect and a Lustre parallel file system built on Data Direct Networks' SFA12KX EXAScaler storage platform.

Carnegie Mellon University computer scientists looked to Pittsburgh Supercomputing Center supercomputer Blacklight in their construction of Claudico, a poker-playing artificial intelligence. Claudico came up short against the world's best poker players, but what the scientists have learned spells good news for medical decision-making.

At the recent Internet2 Global Summit iSGTW sat down with George Komatsoulis to talk about the state of distributed research and the NIH Commons, a scalable virtual environment to provide high-performance computing and data storage for bio-medical research. When implemented, the Commons will create a marketplace for digital bio-medical resources, driving down costs and democratizing access.

The 25 April Nepal earthquake has killed more than 7,000 people and destroyed hundreds of thousands of homes. The deadliest earthquake in Nepal since 1934, the tremor killed at least 19 climbers and crew on Mount Everest and reportedly produced casualties in the adjoining countries of Bangladesh, China, and India.

In response, scientists at The Ohio State University and the University of Minnesota are directing supercomputing resources to aid in the disaster relief.
