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?
One of the highlights of the recent TedxCERN conference was a talk given by Ian Foster, widely known as one of the founders of grid computing. He also spoke to an audience of CERN IT department staff about Globus Online and the challenges of big data.
Niall Gaffney has managed some of the richest astronomical data ever recorded in terms of scientific and public impact. In his new role at the Texas Advanced Computing Center (TACC), Gaffney will oversee the center's big data strategy, and will help TACC address challenges with core techniques and technologies.
Scientists at the University of Oklahoma are developing advanced data analysis techniques to discover why some storms generate tornadoes and others do not. Read about these techniques and their potential impacts on early warning systems and forecasts.
With access to significantly more computational power, researchers can provide more accurate earthquake predictions with the potential to save lives and minimize property damage. Read about advances in developing code to cut both research times and energy costs in simulating seismic hazards.
Renowned computer scientist Paul Messina delivers Peebles Memorial Lecture at Indiana University in Bloomington, US. The university awarded Messina the distinguished Thomas Hart Benton Mural Medallion at the dedication and launch of Big Red II, the fastest university-owned supercomputer in the nation.
In 2012, the United States suffered its worst drought in 24 years, which led to the worst harvest yields in nearly two decades. Read how scientists are using this data to validate crop yield and climate impact models that simulate the effects of climate on agriculture.
City lights, sand dunes, and glaciers –oh my! Take a look at NASA’s eye-catching images of Earth from orbit, including true-color satellite images, Earth science visualizations, and time lapses from the International Space Station.
The University of Texas at Austin and TACC competed against the top supercomputing centers and universities to claim one of the most advanced systems in the world — and won. The prize, an estimated $50 million-plus investment over a four-year period.
On February 15, 2013, as an asteroid entered Earth’s atmosphere and exploded over the Chelyabinsk region in the Russian Urals. Many amateur videos from the region captured the asteroid streaking across the sky and exploding in a bright light. Read about the science behind the atmospheric event and similar impacts on Jupiter.
We are living in the golden age of exoplanets — over 800 are known, and new discoveries are announced weekly. Find out about the vital role high-performance computing is playing in enabling these discoveries.
Faced with the daunting prospect of profiling the complexities of the immune system, researchers at Harvard Medical School/Business School enlisted the help of the world’s largest community of software experts on the site TopCoder. A recent paper in Nature Biotechnology indicates a cultural shift in academia with experts engaging the collective skills of those outside their community, in order to help them overcome methodological barriers to their work.
With more than 10,000 species of birds known to exist, scientists know little about their diversity and development over time. Freely licensed software developed at the University of Utah, US, has enabled researchers to pinpoint a single gene responsible for some very glamorous hairdos.
High-performance computing veteran Thomas Sterling will be delivering a keynote speech on HPC achievement and impact at this year's International Supercomputing Conference in Leipzig Germany (ISC'13). He speaks exclusively to Nages Sieslack...
