“Envision,” a tool developed with backing from the Zofnass Program for Sustainable Infrastructure at GSD, provides a comprehensive framework for governments and industry to evaluate infrastructure projects of all types and sizes based on environmental, economic, and community benefits.

The first Design Fair at the Harvard School of Engineering and Applied Sciences (SEAS) displayed the wealth of ideas that have emerged at SEAS throughout this past academic year.

Harvard’s Center for Geographic Analysis will work with United Nations University on a system that will allow users to track and map wildlife crime, and how it is related to a host of socioeconomic factors.

University of Chicago evolutionary biologist Jerry Coyne says that dysfunction within American society promotes high levels of religious belief that in turn blocks general acceptance of evolutionary theories.

Nicholas Christakis, whose research explores how everything from obesity to smoking to happiness spreads among our social networks, is turning his attention to the past, exploring why and how we became the social animals we are.

A Harvard authority on ancient Iraq spent several years studying clay tablets looted from that nation, which had been stored in a World Trade Center building that was destroyed on 9/11. The tablets eventually were retrieved, restored, translated, and returned.

A Harvard engineering class helps find a metric for a computer scheme that tracks gang violence.

The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering and Applied Sciences.

Climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered that particulate pollution in the late 20th century created a “warming hole” over the eastern United States — that is, a cold patch where the effects of global warming were temporarily obscured.

Steven Raichlen, author of “The Barbecue Bible” and “Planet Barbecue,” discussed on barbecue’s origins among early humans and barbecue customs around the world in a recent Harvard talk.

Two of Harvard’s leading social scientists discussed the way that humans make decisions, and whether having more choices really makes us happier.

Executives from a leading debris-recovery firm, Phillips & Jordan Inc., were at Harvard on April 19 to discuss challenges and lessons learned in two decades of aiding the biggest cleanup efforts in the United States.

Harvard researchers compiled ice and sedimentary core samples collected from dozens of locations around the world, and found evidence that while changes in Earth’s orbit may have touched off a warming trend, increases in CO2 played a far more important role in pushing the planet out of the ice age.

A new book by Harvard astronomer Dimitar Sasselov explains the revolution in understanding the universe that views life as a natural part of planetary evolution and that has researchers on the brink of finding worlds that echo this one.

Harvard scientists have taken a critical step toward building a quantum computer — a device that could someday harness subatomic particles such as electrons to perform calculations far faster than the most powerful supercomputers.

Vinothan Manoharan, an assistant professor of chemical engineering and physics at the School of Engineering and Applied Sciences, wants to make self-assembly — when particles interact with one another and spontaneously arrange themselves into organized structures — happen in the laboratory to treat life-threatening diseases or manufacture useful objects.

Free water purification is needed to head off more than a million childhood deaths from diarrhea each year, says Gates Professor of Developing Societies Michael Kremer.

New research from the Harvard School of Public Health suggests that seemingly small changes in summer temperature swings may shorten life expectancy for elderly people with chronic medical conditions, and could result in thousands of additional deaths each year.

The U.S. energy picture has changed dramatically in recent years, with a flood of shale gas making natural gas a more attractive fuel option and the opening of new supplies cutting U.S. dependence on Middle Eastern oil, an energy expert says.

New research by astronomers at the University of Utah and the Harvard-Smithsonian Center for Astrophysics shows that supermassive black holes can grow big by ripping apart double-star systems and swallowing one of the stars.

Among the advances linked to Harvard is one that came in a field not normally associated with the University: the culinary arts. Cooks use a professor’s 1850s invention, baking powder, as a time-saving replacement for yeast.

The renovation of Harvard’s Sherman Fairchild Building may have seemed inconsequential to the casual observer because the exterior barely changed. However, as a result of a two-year project to accommodate the Stem Cell and Regenerative Biology Department (SCRB), the interior has been transformed into one of the University’s greenest and most efficient laboratory spaces.

Students participating in the Harvard College Innovation (I3) Challenge this year generated dozens of promising ideas to improve the quality of daily life.

“X-Rays of the Soul: Rorschach and the Projective Test,” at Harvard’s Collection of Historical Scientific Instruments, tells the story of the projective test movement and portrays the heady confidence that science could be used to extract and access the most human parts of human beings.

The bond between Harvard and Silicon Valley is a close one. The region is home to a powerful network of alumni willing to offer mentorship to students and recent graduates who are dreaming big. Taking advantage of that network, SEAS and HBS recently came together to organize the trip to Palo Alto.

Inspired by a spherical toy that expands and collapses, researchers at Harvard and MIT have created a new type of engineered capsule, called a “buckliball,” that exploits the phenomenon of buckling. The buckliball is the first morphable structure to incorporate buckling as a desirable engineering design element.

Seven years ago, astronomers boggled when they found the first runaway star flying out of our galaxy at a speed of 1.5 million miles per hour. The discovery intrigued theorists, who wondered: If a star can get tossed outward at such an extreme velocity, could the same thing happen to planets? New research shows that the answer is yes.

If the Amazon becomes drier, as predicted by climate models, the forest will see a shift toward tree species that are drought tolerant and, in some cases, will lead to a savannah’s mix of trees and grasses, Robert F. Kennedy Visiting Professor Guillermo Goldstein says.

Jason Ur, the John L. Loeb Associate Professor of the Social Sciences, worked with Bjoern Menze of MIT to develop a system that identified ancient settlements based on a series of factors — including soil discolorations and the distinctive mounding that results from the collapse of mud-brick settlements.

In 1978, while a student at Harvard Business School, Dan Bricklin conceived of VisiCalc, the first electronic spreadsheet program for personal computers. The result helped to spark a digital revolution in business and made desktop computers a must-have item in many offices.
