Brookhaven National Laboratory is preparing for a new wave of discoveries. PHENIX is in its final runs, but superPHENIX waits in the wings.

Upgrading its PHENIX detector and Relativistic Heavy Ion Collider marks the beginning of an exciting new chapter for BNL and high-energy physics.

 XSEDE15, the fourth annual conference, will showcase the discoveries, innovations, challenges and achievements of those who utilize and support XSEDE resources and services, as well as other digital resources and services throughout the world.

This year's theme is "Scientific advancements enabled by enhanced cyberinfrastructure."

XSEDE15 takes place July 26-30 at the Renaissance St. Louis Grand Hotel in the heart of downtown St. Louis, Missouri.

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.

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.

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.

Big data opens doors previously closed to researchers, yet the volume of data sends scientists looking for analytical tools to bring order from the informational cacophony. Prior to tools like Bioconductor, there were few options for working with quantitative data types; a discordant score for deciphering the human genetic code was the result.

Today, genomic analysis machines create a common language for users, and build a worldwide community to foster developers from among subject matter experts. These instruments make beautiful music from a mass of genomic information.

Researchers in Switzerland have taken inspiration from fossils to discover how DNA could be used to reliably store data for over two million years. They stored 83 kilobytes of data — containing the text from the Swiss Federal Charter of 1291 and the English translation of the Method of Archimedes — on DNA, which was subsequently encapsulated in silica to mimic the protective shell provided by fossilized bone.
