Seismologists have always relied on surface observation to piece together models of what they thought Earth’s interior looked like. These models served them well for years, but they were unable to map out the planet’s interior with certainty, until now. A team of scientists is using the powerful US Titan supercomputer to do just that.

Mutations pose a risk to crop yields and our ability to feed a burgeoning population. With the aid of cloud computing clusters, Cornell researchers were able to predict where bad mutations are likely to occur. Genetic editing will remove these harmful mutations and allow breeders to continue increasing yield gains.

Buying a supercomputer can be a tough sell for administrators to make. A study by Clemson University researchers may change the argument.

They’re only 1/100th the width of a human hair, but these little sensors are kind of a big deal. Dubbed geometrically encoded magnetic sensors (GEMs), they have the ability to change shape once inside human tissue – and they provide greater accuracy than current technology.

Naturally occurring crystalline structures called zeolites have the ability to separate molecules, speed chemical reactions, rearrange atomic bonds, and break down long chains of hydrogen and carbon atoms. Scientists screened a large database of possible zeolite structures to find a few that can lead to cheaper ethanol and better engine lubrication. What they’ve discovered could mean greater engine efficiency and big savings for you.

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.

The Large Synoptic Survey Telescope will provide an unprecedented look into the cosmos, and the Dark Energy Science Collaboration is preparing a variety of analyses for the huge data sets it will produce. In anticipation of their needs, Fermilab is developing innovative software tools and approaches.

In a TED talk video, Altimeter industry analyst Susan Etlinger discusses the ethical implications of collecting big data, and gives her perspective on how to best analyze data that both extracts real insights and builds trust.

iSGTW recently followed up with Etlinger on her proposed framework and how she believes we should approach traditional analytics methodologies to ensure they account for the variations and complexities of big data.

The so-called 'long-tail' of research is an important and often underserved community, compared with other areas of science that are well supported by national supercomputing infrastructure. Cloud computing is making it easier to deliver tailored services to these researchers and is enabling new research collaborations across the globe.

Sometimes solar eruptions have a benign effect, perhaps only creating a spectacular aurora display. But at other times, they can be very dangerous to life on Earth. Stanford solar physicists Monica Bobra and Sebastien Couvidat have developed live forecasting techniques to provide more time to react.

Criminals use technology to exploit their victims, but law enforcement lacks the time and expertise to develop the technology to respond. A student-led project recently won a $3.6 million DARPA grant to change that dynamic by devising cyber tools that identify online human trafficking activity.
