Physicists can tell the future — or at least foresee multiple possible versions of it. They do this through computer simulations. Simulations can help scientists predict what will happen when a particular kind of particle hits a particular kind of material in a particle detector. But physicists are not the only scientists interested in predicting how particles and other matter will interact. This information is critical in multiple fields, especially those concerned about the effects of radiation. Physicists and other scientists use the GEANT4 toolkit to identify problems before they occur.

Monday 29 September marks the 60th anniversary of the founding of the European Organization for Nuclear Research, otherwise known as CERN, located near Geneva, Switzerland. A new book, entitled 'From Physics to Daily Life', highlights some of the many ways in which technology developed at CERN has impacted upon society at large.

Bob Jones, the head CERN openlab, writes in this book about the growth of distributed computing and the vital role this technology plays across a wide range of academic fields and business sectors.

The Research Data Alliance (RDA) seeks to build the social and technical bridges that enable open sharing and reuse of data, so as to address the cross-border and cross-disciplinary challenges faced by researchers. This September, the RDA will be hosting its Fourth Plenary Meeting in Amsterdam, The Netherlands. Ahead of the event, iSGTW speaks to Gary Berg-Cross, general secretary of the Spatial Ontology Community of Practice and a member of the US RDA advisory committee. Berg-Cross is also co-chair of the RDA working group on data foundation and terminology.

Next-generation sequencing (NGS), in which millions or billions of DNA nucleotides are sequenced in parallel, is the backbone of novel discoveries in life sciences, anthropology, social sciences, biomedical sciences and plant sciences. Read about the SoyKB and iPlant collaboration that is taking plant sciences to the next level.

Last week, iSGTW attended the International Supercomputing Conference (ISC’14) in Leipzig, Germany. The event featured a range of speakers representing a wide variety of research domains. Awards given by PRACE and Germany’s Gauss Centre for Supercomputing highlighted some of the outstanding research on show at the event. And, of course, the new TOP500 list of the world’s fastest supercomputers was announced.

With global data output growing rapidly, it is vital that researchers come together to build the social and technical bridges required to enable open sharing of research data. The organization charged with achieving this is the Research Data Alliance (RDA), which recently celebrated its first anniversary.

Last month, the RDA held a plenary meeting in Dublin, Ireland. The 497 attendees at the event engaged in discussion on a wide variety of topics, ranging from the role of publishers and persistent identifiers to heritage data and legal interoperability. Data applications discussed also included geospatial information, marine observation, food production, and urban quality of life indicators.

Last month, CERN played host to the CineGlobe International Film Festival. The event featured a hackathon event organized by the Tribeca Film Institute, as well as music produced through data sonification.

iSGTW speaks to Mark Parsons, who was recently appointed secretary general of the Research Data Alliance. This global organization celebrates its first anniversary next month and will be holding its third plenary meeting in Dublin, Ireland, from 26-28 March, 2014.

Parsons tells iSGTW why it is important for researchers to share their data and explains how the RDA is seeking to harness enthusiasm within the community to bring about a 'culture change' in the way researchers deal with data. He also argues that the greatest barriers to increased data sharing are often social, rather than technical.

In the fight against HIV, better understanding of the structure of the virus could lead to new antiretroviral drugs. University of Illinois researchers recently used molecular simulations on the Blue Waters supercomputer to determine the chemical structure of the HIV capsid, which plays a key role in debilitating the immune system.

Sea level is projected to rise by up to a meter by 2100 due to human-caused increases in greenhouse gases. However, a new study indicates that cutting four kinds of heat-trapping emissions could have an impact this century. Such progress is possible because these pollutants cycle through the atmosphere relatively quickly.

Despite global agreements to reduce the emissions of greenhouse gases, current efforts may prove inadequate without more effective – and more affordable – carbon control technologies. A recent breakthrough means next generation carbon scrubbers may soon be at hand.

NASA's Aqua satellite captures the explosive growth of springtime phytoplankton, obtaining data that will improve scientists’ understanding of global dynamics and processes, and aid the development of interactive Earth models for predicting global change.

Last week, the results of a survey were published in the journal Scienceshowing that many non-scientific factors often come into play when researchers select software for modeling and other purposes. Could researchers' inability to weigh up the relative pros and cons of the software alternatives available to them based on their scientific merits be undermining the scientific method?
