  • From overviews of landscapes to inner views of cells

    The photographs are stunning abstracts that look as though they should be hung above a mantle or in a fine art gallery. But these aren’t primarily works of art; they…

  • Tracking down the seat of moral reasoning

    Moral philosophers have long grappled with ethical questions, creating hypotheticals that test basic beliefs about right and wrong.  For example: A trolley is running down a track out of control.…

  • Harvard brings the Earth to high school

    Steam vents in Yellowstone National Park are part of the area’s unique environment, seen in a case study exploring Yellowstone and the reintroduction of wolves into the park. This case study is part of a new environmental science course for high school science teachers.

  • Do sports and statistics constitute a ‘dream team’?

    Many argue it’s the reason the curse was finally reversed. A few say it has revolutionized the game. “Sabermetrics” — the statistical analysis of baseball data — pervades sports conversation today. But how many people are aware that analytical statistics can make powerful contributions to other sports, like say, pingpong? Well, for a start there are the more than 100 statisticians and sports enthusiasts — in this case, often one and the same — who came together at the Harvard University Science Center Sept. 29 for the first “New England Symposium on Statistics in Sports” (NESSIS).

  • Ancient practice sans theory

    Move over, Archimedes. A researcher at Harvard University is finding that ancient Greek craftsmen were able to engineer sophisticated machines without necessarily understanding the mathematical theory behind their construction.

  • Colorizing classic statues returns them to antiquity

    For artists of the Renaissance, the key to truth and beauty lay in the past. Renaissance artists assiduously studied the sculptures and monuments of Greece and Rome and emulated them…

  • Digging for solutions to energy crisis

    In the 1970s, Iceland was one of the poorest countries in Europe. Today it is one of the richest, with a per capita GDP higher than that of Denmark, from which it won full independence in 1944.

  • Male voice pitch predicts reproductive success in hunter-gatherers

    Deeper voice pitch predicts reproductive success in male hunter-gatherers, according to a new study from researchers with Harvard University, McMaster University, and Florida State University. This is the first study…

  • ‘Hot’ ice could lead to medical device

    Harvard physicists have shown that specially treated diamond coatings can keep water frozen at body temperature, a finding that may have applications in future medical implants.

  • CfA reveals Magellanic Clouds are first-time visitors

    The Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) are two of the Milky Way’s closest neighboring galaxies. A stunning sight in the southern hemisphere, they were named after the Portuguese explorer Ferdinand Magellan, who explored those waters in the 16th century. For hundreds of years, these galaxies were considered satellites of the Milky Way, gravitationally bound to our home galaxy. But new research by Gurtina Besla of the Harvard-Smithsonian Center for Astrophysics (CfA) and her colleagues shows that the Magellanic Clouds are recent arrivals — on their first visit to the Milky Way’s neighborhood.

  • Biohybrid of elastic film and muscle cells packs a punch

    In an innovative marriage of living cells and a synthetic substrate, bioengineers at Harvard University have found that a rubberlike, elastic film coated with a single layer of cardiac muscle cells can semi-autonomously engage in lifelike gripping, pumping, walking, and swimming.

  • Creating a computer currency

    Computer scientists are using the latest version of peer-to-peer video sharing software to explore a next-generation electronic commerce model that uses bandwidth as a global currency.

  • Harvard astronomers share dark prize

    Two teams who upset everyone’s ideas about how the universe works and its future will share the $500,000 Gruber Cosmology Prize for discovering that 70 percent of the universe is nothing but a strange form of energy.

  • Harvard launches major initiative to help design international climate agreements

    Harvard University announced in early July a two-year project to help identify key design elements of a future international agreement on climate change, drawing on the ideas of leading thinkers from academia, private industry, government, and advocacy organizations, both in the industrialized world and in developing countries.

  • Oceans are back on Mars

    Since spacecraft sent back the first close-up images of Mars more than 30 years ago, some experts have insisted that oceans once existed on the now dry, cold planet. Critics have maintained for decades that such an idea is the product of unrestrained imaginations. Now, a study published in today’s (June 14) issue of the British journal Nature reports new evidence that our neighbor in space once boasted an ocean or oceans as big, relative to planet size, as the Atlantic on Earth.

  • Rajan Sonik hopes to cure bodies while energizing hearts and souls

    Rajan Sonik arrived at Harvard four years ago aspiring to a career in science or maybe law, but a 14-year-old boy with sickle cell disease Sonik met in his sophomore year through a hospital mentoring program changed everything.

  • Single spinning nuclei in diamond offer a stable quantum computing building block

    Surmounting several distinct hurdles to quantum computing, physicists at Harvard University have found that individual carbon-13 atoms in a diamond lattice can be manipulated with extraordinary precision to create stable quantum mechanical memory and a small quantum processor, also known as a quantum register, operating at room temperature. The finding brings the futuristic technology of quantum information systems into the realm of solid-state materials under ordinary conditions.

  • ‘Digital immigrants’ teaching ‘digital natives’
