Deep learning of aftershock patterns following large earthquakes
Phoebe M. R. DeVries, Fernanda Viégas, Martin Wattenberg & Brendan J. Meade
"Aftershocks are a response to changes in stress generated by large earthquakes and represent the most common observations of the triggering of earthquakes. The maximum magnitude of aftershocks and their temporal decay are well described by empirical laws (such as Bath’s law and Omori’s ... Read More
Unraveling the Stellar Content of Young Clusters
"CfA astronomers Rafael Martinez-Galarz and Howard Smith and their two colleagues have developed a new statistical analysis technique to address the problem of confused SEDs in clustered environments. Using the highest spatial resolution images for each region, the team identifies the distinguishable stars (at least this many are in the cluster) and their emission at ... Read More
Revisiting the Six City Study
"Last June, eight new Harvard-affiliated researchers revisited the study, using new technologies and innovations in statistical analysis and examining Medicare data—the largest and most public dataset available documenting the health of U.S. citizens—thus presumably averting renewed charges of secret science (an issue raised anew by current EPA administrator Scott Pruitt). Their findings breathe new life ... Read More
Mapping Invisible Ocean Pollutants
Prof. Elsie Sunderland's lab seeks to build a picture of pollutants which threaten our oceans.
“People struggle with this idea that we could impact planetary level processes. But we do. There’s irrefutable
evidence on many, many scales that we’re changing the natural functioning of these ecosystems.”

Air Pollution and Mortality in the Medicare Population
ABSTRACT - We constructed an open cohort of all Medicare beneficiaries (60,925,443 persons) in the continental United States from the years 2000 through 2012, with 460,310,521 person-years of follow-up. Annual averages of fine particulate matter (particles with a mass median aerodynamic diameter of less than 2.5 μm ) and ozone were estimated according to the ... Read More
A Language Out of Nothing
Searching for the nature of speech, sign, and universal grammar
"Davidson’s work on sign languages spans the divide between applied and theoretical linguistics, contributing to both abstract debates about language in the mind and questions with immediate impacts on people’s lives. Harvard’s small but formidable linguistics department thrives on its interest in the union of theory ... Read More

NESE: Large-Scale Extendable Storage
"As big data becomes a common analytical tool in fields from the sciences to the humanities, Harvard’s computer infrastructure experts are turning their attention to an increasingly pressing question: How do you manage it all?
In recent years, Harvard invested in the Odyssey computing cluster, whose 60,000 CPUs provide the sheer computing horsepower needed to crunch ... Read More
New Module Search ToolsThe RC/Informatics portal now has a new application for searching modules in the new module system.
This search tool includes all of the modules in the new module system, and provides key information, including application descriptions, how to load the module, and in many cases, build notes that help describe the difference between various builds.
A command ... Read More

Altered diet can quickly change gut microbiome in humans Animal and plant-based foods have contrasting effects on the human gut microbiome. Credit: John Kaufmann, http://www.jek2004.com
Led by the Turnbaugh lab in the Center for Systems Biology at Harvard University, researchers have discovered that the microbes found in the human gut respond rapidly to a new diet. The researchers placed ten people on two defined ... Read More
The Clean Energy ProjectThe Clean Energy projects searches for next generation plastic solar cell materials using RC computational resources. The project, led by Professor Alán Aspuru-Guzik, has generated data about 2.3 million candidate compounds for organic electronic materials. To find out more about the project see here.
Migratory behavior of planetary systemsUsing Odyssey to run numerical integrations, research on how planetary systems evolve and migrate has provided new insights. The centuries old theory of orderly planetary system architectures is being challenged by new evidence that suggests many planetary systems underwent a period of upheaval during which giant planets “migrated” from where they formed. For a full ... Read More
The Equality of Opportunity ProjectHarvard economists measure the upward mobility of children in the bottom fifth of U.S. households using big data and Odyssey. The economists found that there is substantial variation in the U.S. in the prospects for escaping poverty and some of the strongest predictors of upward mobility are social capital and family structure. For more details ... Read More
Temperature extremes unprecedented in the past 600 yearsHarvard scientists use Odyssey to run climate models measuring the scale and frequency of recent warm temperature extremes. The results led to conclusive evidence that the summers of 2005, 2007, 2010 and 2011 in the high northern latitudes were warmer than those of all prior years back to 1400.
