In ES 227, “Medical Device Design,” SEAS students are given the opportunity to solve practical problems in a hospital setting, trying out the tools, learning about their use in real-world situations, and, in some cases, even sitting in on surgical procedures.

The Dataverse Network Project, spearheaded by Harvard’s Institute for Quantitative Social Science, provides archival storage for research projects whose records are on outmoded technology formats.

The regeneration of the region’s forests during the last 150 years is an environmental gift that New Englanders shouldn’t squander with thoughtless development, the director of the Harvard Forest said in a talk at the Harvard Museum of Natural History.

Among the many ways that participation in Alcoholics Anonymous (AA) helps its members stay sober, two appear to be most important — spending more time with individuals who support efforts toward sobriety and increased confidence in the ability to maintain abstinence in social situations.

New research from the Harvard-Smithsonian Center for Astrophysics shows that some old stars might be held up by their rapid spins, and when they slow down, they explode as supernovae. Thousands of these “time bombs” could be scattered throughout our Galaxy.

Using a new technique, researchers at the Harvard School of Engineering and Applied Sciences have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction.

Students in Earth and Planetary Sciences kicked off their academic year early, spending a late-August week in paradise, observing Hawaii’s volcanoes, green and black sand beaches, and overarching geologic splendor.

Insomnia is costing the average U.S. worker 11.3 days, or $2,280, in lost productivity every year, according to a study led by Ronald Kessler of Harvard Medical School.

Harvard College freshmen got their first taste Aug. 26 of the world of ideas awaiting them over the next four years in a talk by Professor Nicholas Christakis, who delivered the 2011 Opening Days Lecture, “Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives.”

Hanspeter Pfister, an expert in high-performance computing and visualization, is part of an interdisciplinary team collaborating on the Connectome Project at the Center for Brain Science. The project aims to create a wiring diagram of all the neurons in the brain.

Harvard and Stanford chemists have created and purified an organic semiconductor with excellent electrical properties, simultaneously confirming a screening process being used to find new photovoltaic materials.

New 3-D nanostructured chip identifies unknown liquids instantly, offering a litmus test for surface tension.

Harvard scientists are leading an international collaboration that aims to coordinate research, data collection, scientist training, and analysis of information gleaned from two networks of forest plots, one through the Harvard-affiliated Center for Tropical Forest Science and the second created by Chinese scientists.

New research shows that aurorae on distant “hot Jupiters” could be 100 to 1,000 times brighter than Earth’s aurorae. “I’d love to get a reservation on a tour to see these aurorae,” said lead author Ofer Cohen, a postdoctoral fellow at the Harvard-Smithsonian Center for Astrophysics.

Researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH) have developed a one-micrometer-resolution version of the intravascular imaging technology optical coherence tomography (OCT) that can reveal cellular and subcellular features of coronary artery disease.

New website opens a window onto naturalist Charles Darwin’s struggle with the complexities of gender, and illustrates how culture affects science’s vaunted neutrality.

Harvard Summer School students broke ground June 29 for the biennial archaeology class investigating the long history of Harvard Yard. Students will resume the search for traces of the Harvard Indian College, where the College’s first Indian students lived and studied.

A quantitative analysis of the streams, drips, and coils of artist Jackson Pollock by a Harvard mathematician and others reveals that he had to be slow and deliberate to exploit fluid dynamics as he did.

A Harvard University study built around an innovative economic game indicates that, at least for our younger selves, the desire for equity often trumps the urge to maximize rewards.

From across the University, members of the information technology community gathered for the first Harvard IT Summit.

Three Harvard affiliates nab a big new-media prize, and marvel at the University’s converging forces that mix the digital age with traditional scholarship.

The Arboretum is so serene and languid it can seem almost imaginary. On a warm summer day, dogs and runners and bicyclists all share the nearly silent space under the shade of giant and rare trees of odd shapes and sizes.

A symposium sponsored by Harvard’s Berkman Center for Internet & Society explored the design of public and private spaces in the digital realm.

Researchers are examining the Harvard Semitic Museum’s collection of ancient glass for clues about the people who made it and their interactions with other societies through trade.

Ralph Mitchell, a Harvard professor and authority on cultural heritage microbiology, investigates “fingerprints” left on the walls of Egyptian King Tutankhamen’s tomb by ancient microbes.

Harvard Medical School researchers have traced the influence of genes from sub-Saharan Africa in European, Middle Eastern, and Jewish populations, quantifying the intermingling that occurred over many generations.

A researcher at the Harvard-Smithsonian Center for Astrophysics has uncovered a new way that stars end their lives, in a bright, fast explosion that appears different from the known characteristics of the stellar cataclysms called supernovas.

Astronomy Professor Alyssa Goodman is helping to bring astronomy to area schools, founding an “ambassador” program that combines with new software to provide an interface on the universe for students and researchers alike.

New England forests are the focus of a new exhibit at the Harvard Museum of Natural History, funded by the largest donation in the institution’s history.

For their capstone project in the course ES 96: “Engineering Design Seminar,” 16 SEAS students conducted an analysis of the geothermal heating and cooling system that serves Radcliffe’s Byerly Hall.
