All Science & Tech

  • Chinese cities, by design

    A new three-year, three-city course at the Harvard Graduate School of Design gives students an immersive learning experience in some of China’s fast-growing frontier cities.

  • Seeking to connect on water issues

    The U.S. lacks a national water policy, resulting in pushing and pulling by a wide array of competing interests in managing the nation’s water supply, said experts at a Radcliffe symposium.

  • Applied physics as art

    Harvard researchers spray-paint ultrathin coatings that change color with only a few atoms’ difference in thickness.

  • A monumental task

    Harvard’s Corpus of Maya Hieroglyphic Inscriptions Program is making a digital scan of Harvard Yard’s Chinese stele as part of a conservation effort aimed at preserving the ornate gift from Harvard’s Chinese alumni on Harvard’s 300th birthday.

  • A close eye on population growth

    Joel Cohen, head of the Laboratory of Populations at Rockefeller and Columbia universities, looked at the latest projections for world population growth, and factors that could alter them, in a Harvard talk.

  • ‘Point of no return’ found

    Using a continent-spanning telescope, an international team of astronomers has peered to the edge of a black hole at the center of a distant galaxy. For the first time, they have measured the black hole’s “point of no return” — the closest distance that matter can approach before being irretrievably pulled into the black hole.

  • An engineering landmark

    The Harvard School of Engineering and Applied Sciences celebrates a landmark degree accreditation, and a broadening, flexible future of programs that break down academic barriers.

  • ‘Silent Spring,’ 50 years on

    Environmentalists and faculty members gathered at Sanders Theatre to mark the 50th anniversary of the publication of Rachel Carson’s “Silent Spring,” which catalyzed the environmental movement in its impassioned presentation of the impact of chemicals on nature.

  • An invasion of New England

    While new species naturally expand to other places and sometimes disrupt the scene when they arrive, the pace of introduction of invasive species has picked up enormously over the past century and a half, stressing and transforming New England forests.

  • Managing just fine

    Measurements of stress hormones and self-reports of anxiety show that leaders in stable organizations experience less stress than their subordinates, likely because they have greater control over their office lives.

  • Spoiled opportunity

    Republican objections to a climate change “tax” have stained the cap-and-trade approach to tackling climate change, making it politically unpalatable, even though it proved effective at fighting acid rain over the past two decades.

  • Emergency planning

    Six of Harvard’s deep thinkers on climate change and sustainability took the stage Sept. 18 in the second annual Harvard Thinks Green.

  • Alan Turing at 100

    Harvard’s Collection of Historical Scientific Instruments celebrates the 100th birthday of Alan Turing, whose ideas theorized the first computers, spurred the science of artificial intelligence, and — oh yes — helped save the Allies during World War II.

  • Figuring out fairness

    A new Harvard study suggests that children as young as 3 consider merit — a key part of more-advanced ideas of fairness — when distributing resources.

  • Planets form in cosmic maelstrom

    At first glance, the center of the Milky Way seems like a very inhospitable place to try to form a planet. New research by astronomers at the Harvard-Smithsonian Center for Astrophysics shows that planets still can form in this cosmic maelstrom.

  • Needle beam stays on point

    A Harvard-led team of researchers has demonstrated a new type of light beam that propagates without spreading outward, remaining very narrow and controlled along an unprecedented distance. It could greatly reduce signal loss for on-chip optical systems and may eventually assist the development of a more powerful class of microprocessors.

  • Capturing the stars

    Alex Parker, a postdoctoral fellow at the Harvard-Smithsonian Center for Astrophysics, sees astronomical data as art as well as science.

  • Super gel

    A team of experts in mechanics, materials science, and tissue engineering at Harvard has created an extremely stretchy and tough gel that may suggest a new method for replacing damaged cartilage in human joints.

  • ‘Thou shall be inventive’

    Chef-mixologist Dave Arnold and kitchen science author Harold McGee kicked off the third season of the “Science and Cooking” lecture series, looking at both the history and versatility of food.

  • Clues in the cucumber’s climb

    Harvard researchers, captivated by a strange coiling behavior in the grasping tendrils of the cucumber plant, have characterized a new type of spring that is soft when pulled gently and stiff when pulled strongly.

  • Perfecting optics

    Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses.

  • Merging the biological, electronic

    For the first time, Harvard scientists have created a type of cyborg tissue by embedding a 3-D network of functional, biocompatible, nanoscale wires into engineered human tissues.

  • Listening for clues

    Baby songbirds learn to sing by imitation, just as human babies do. So researchers at Harvard and Utrecht University, in the Netherlands, have been studying the brains of zebra finches — red-beaked, white-breasted songbirds — for clues to how young birds and human infants learn vocalization on a neuronal level.

  • Butterflies heading north

    A Harvard study reveals that over the past 19 years, a warming climate has been reshaping Massachusetts butterfly communities.

  • Using evolution to understand pollution

    A tool rarely used to understand the impact of pollution on the natural world is evolution, an oversight that an environmental toxicologist says is robbing investigators of important information.

  • Soft robots go for color, camouflage

    Researchers have developed a system — inspired by nature — that allows soft robots to either camouflage themselves against a background, or to make bold color displays. Such a “dynamic coloration” system could one day have a host of uses, ranging from helping doctors plan complex surgeries to acting as a visual marker to help search crews following a disaster.

  • Soft Robots, in color

    Having already broken new ground in robotics with the development, last year, of a class of “soft”, silicone-based robots based on creatures like squid and octopi, Harvard scientists are now working to create systems that would allow the robots to camouflage themselves, or stand out in their environment.

  • Re-creating a slice of the universe

    Scientists at the Harvard-Smithsonian Center for Astrophysics and their colleagues at the Heidelberg Institute for Theoretical Studies have made it possible to build a universe from scratch.

  • Making sense of memory

    It happens to all of us: We think we learned of the Sept. 11 attacks from a radio report, when, in fact, the news came from a co-worker; we’re sure the robber running from the bank was tall, when actually he was short; we remember waking up at 7 yesterday, when 8 is closer to the truth. Such “false memories,” unavoidable in everyday life, can have disastrous consequences in courtrooms and other settings where exactitude matters.

  • Deep glow

    Dancers and scholars explored the art and science of bioluminescence during “Living Light” July 31 at the Science Center.
