All Science & Tech

  • Urgent prep work

    Humanitarian relief workers and climate scientists gathered in Cambridge this week to discuss the connection between climate change and humanitarian disasters and what relief workers can learn from science.

  • The trouble with Kepler

    A malfunction aboard NASA’s Kepler Space Telescope has jeopardized what has been one of the agency’s highest-profile missions, one that has revealed a galaxy rich with planets. The Gazette talked to Astronomy Professor Dimitar Sasselov, one of the mission’s principal investigators, about the implications.

  • The nearness of you

    In research described earlier this year in the Personality and Social Psychology Bulletin, Elinor Amit, a College Fellow in psychology, along with two collaborators, Cheryl Wakslak and Yaacov Trope, showed that people increasingly prefer to communicate verbally (versus visually) with people who are distant (versus close) — socially, geographically, or temporally.

  • How to protect cyclists

    Four Harvard School of Public Health students presented recommendations to the Boston City Council on how to make Boston a safer city for cyclists.

  • Building with an eye on the sky

    Real estate developer Jonathan Rose highlighted recent progress in incorporating green features into affordable housing projects, saying America’s cities provide an energetic counterpoint to the stagnation in Washington, D.C.

  • Projectile learning

    Students in Matthew Liebmann’s “Encountering the Conquistadors” class recently got a feel for prehistoric life, trying their hands at an ancient weapon called the atlatl.

  • Robotic insects make first controlled flight

    The demonstration of the first controlled flight of an insect-sized robot is the culmination of more than a decade’s work, led by researchers at the Harvard School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering at Harvard.

  • Understanding student weaknesses

    As part of an unusual study that surveyed 181 middle school physical science teachers and nearly 10,000 students, researchers found that the most successful teachers were those who knew what students would get wrong on standardized tests.

  • Seeking fairness in ads

    Latanya Sweeney, Harvard professor of government and technology in residence, wants to add a new factor to the weighting Google uses when delivering online ads, one that measures bias. In a new paper, she describes how such a calculation could be built into the ad-delivery algorithm Google uses.

  • Science in service

    Teams of students from “Engineering Sciences 20: How to Create Things and Have Them Matter” in the Harvard School of Engineering and Applied Sciences are working to create unusual products that are designed to change the world.

  • The problem with predictions

    People would like to predict the future, says author and mathematician David Orrell, but it remains quite a difficult thing to do, even with lots of data at hand.

  • Robot hands gain a gentler touch

    Researchers at the Harvard School of Engineering and Applied Sciences have developed an inexpensive tactile sensor for robotic hands that is sensitive enough to turn a brute machine into a dexterous manipulator.

  • Insignificant, with a lousy future

    Theoretical physicist Lawrence Krauss described a universe with mysterious particles popping in and out of existence, in which the discoveries of dark energy and dark matter have made mankind more insignificant than ever.

  • Pitcher plants provide tipping point

    New research out of the Harvard Forest offers insight on exactly when the tipping point occurs that can disrupt the intricate web of life in a lake.

  • Earth feels impact of middle class

    The rise of the middle class is a bigger environmental challenge than the rising global population, according to Sir David King, the former science adviser to the British government, who urged the adoption of sustainable development as a way to manage growing global demands in a finite world.

  • Water worlds surface

    Astronomers have found a planetary system orbiting the star Kepler-62. This five-planet system has two worlds in the habitable zone — the distance from their star at which they receive enough light and warmth for liquid water to theoretically exist on their surfaces.

  • Putting the stars within reach

    Two communications specialists at the Chandra X-Ray Observatory have authored a guide to the universe, aiming to show people around a universe they say belongs to us all.

  • Warmth across 600 years

    Harvard researchers are adding nuance to our understanding of how modern and historical temperatures compare.

  • Stars align at astronomy reunion

    Harvard astronomers past and present gathered in Cambridge Friday (April 5) for the first-ever reunion of the Harvard Astronomy Department.

  • Fine-tuning online education

    Andrew Ho, research director of HarvardX and an assistant professor at the Harvard Graduate School of Education, spoke with the Gazette about a recent study that found that interspersing online lectures with short tests improved student performance.

  • Lessons from the long-lived

    A gerontologist researcher says his work allows him to connect with “vibrant, engaged, healthy, exciting, and active older people.” He says they live more in the now than other people might believe, and value that.

  • Online learning: It’s different

    By interspersing online lectures with short tests, student mind-wandering decreased by half, note-taking tripled, and overall retention of the material improved, said Daniel Schacter, the William R. Kenan Jr. Professor of Psychology, and Karl Szpunar, a postdoctoral fellow in psychology.

  • Evolutionary oomph

    Scientists may soon be able to turn to one of the most powerful forces in biology — evolution — to help in their quest to develop new synthetic polymers.

  • Tweaking the universe

    In a question-and-answer session, Harvard astronomy chair Avi Loeb explains the new data from the European Space Agency’s Planck satellite.

  • Space and climate change

    A lecturer from the Harvard-Smithsonian Center for Astrophysics says that “dark clouds of gas and dust have the potential to alter Earth’s climate.

  • Sharper view of matter

    In a breakthrough that could one day yield important clues about the nature of matter itself, a team of Harvard scientists has measured the magnetic charge of single particles of matter and antimatter with unprecedented precision.

  • The power of ‘thanks’

    In “Sidetracked: Why Our Decisions Get Derailed, and How We Can Stick to the Plan,” Francesca Gino, an associate professor at Harvard Business School, explores a range of fascinating subjects, including how emotions influence decisions and the often-thorny matter of understanding the perspectives of others. Blending social science and real-world examples, Gino’s book also highlights the science of gratitude.

  • A vision of floating cities

    With the world’s sea levels rising and posing a long-term threat to coastal cities, Nigerian architect Kunlé Adeyemi suggests building houses that float, but, taken together, still function as a community.
