  • Brain navigation

    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.

  • Electrical conductor sparks interest

    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.

  • Gauging forest changes

    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.

  • Light fantastic

    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.

  • A closer look at atherosclerosis

    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.

  • On Darwin and gender

    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.

  • They dig the past

    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.

  • Pollock: Artist and physicist?

    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.

  • Just rewards

    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.

  • For Harvard, an IT summit

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

  • From A to Zeega

    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.

  • In the Arboretum, another world

    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.

  • Hyper-public spaces

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

  • History shines through the glass

    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.

  • Tut, tut!

    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.

  • Finding the genetic trail

    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 supernova that’s super different

    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.

  • A school telescope, through the Internet

    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.

  • A walk through forests — without rain

    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.

  • Deep knowledge

    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.

  • What is geothermal energy?

    Geothermal energy is the natural heat that is stored deep underground (about 1,500 feet down, in the case of the wells at Radcliffe). While the seasons change above ground in…

  • Parenting in context

    In her Fellows’ Presentation, Nancy E. Hill, the Suzanne Young Murray Professor at the Radcliffe Institute, discussed her research into socialization and cultural development in relation to parents’ interaction with children and how this interaction varies across geography, income levels, and ethnicity.

  • Holder’s mission

    U.S. Attorney General Eric Holder on May 6 talked to a Harvard audience about youth exposure to violence as a public health issue — and the need for a public health response.
