All Science & Tech

  • How fish swim

    Scientists have long believed that sunfish, perch, trout, and other such bony fish propel themselves forward with the movement of their tails, while their dorsal and anal fins — the fins on their tops and bottoms — work primarily as stabilizers.

  • Climate change for the long haul

    Human-induced changes to the Earth from emission of greenhouse gases are here to stay, with computer models showing that changes made by 2100 could take 1,000 years to decline.

  • I Am My Filter and more

    Students presented projects Wednesday (April 13) from the Idea Translation Lab, which pushes students to turn ideas into reality and sets them up to take the next steps in project development.

  • Learning to love the irrational mind

    Just how much should we allow “human nature” to guide our politics — and our everyday decision making? Columnist David Brooks and a trio of Harvard analysts debated new findings on the unconscious mind during a panel discussion.

  • The ‘quantum magnet’

    Harvard physicists have expanded the possibilities for quantum engineering of novel materials such as high-temperature superconductors by coaxing ultracold atoms trapped in an optical lattice — a light crystal — to self-organize into a magnet, according to an article in the journal Nature.

  • A match of climate and history

    Professor Michael McCormick has been working with tree-ring experts, bringing the perspective of long-ago writings to understanding environmental conditions.

  • Regimes won’t halt climate change

    Jeffrey Sachs, director of Columbia University’s Earth Institute, says the world should stop waiting for governments to solve the global warming problem. He called on academics to band together to find workable solutions.

  • Fuel cell breakthrough

    Scientists at the Harvard School of Engineering and Applied Sciences and SiEnergy Systems LLC have demonstrated the first macro-scale thin-film solid-oxide fuel cell. This is the first time a research group has overcome the structural challenges of scaling up the technology to a practical size with a proportionally higher power output.

  • Tracking your friends and idols

    Two Harvard undergraduates have developed a website called Newsle that tracks news of Facebook and Linked In contacts.

  • How the lily blooms

    SEAS research has revealed that differential growth and ruffling at the edges of each petal — not in the midrib, as commonly suggested — provide the force behind the lily’s bloom. The work contradicts earlier theories regarding the growth within the flower bud.

  • A quake data clearinghouse

    Within hours of the massive earthquake that struck Japan on March 11, Harvard’s Center for Geographic Analysis had launched a web-based data clearinghouse, the Japan Sendai Earthquake Data Portal, to provide a site where disaster responders can find needed information.

  • Student projects win $50,000 in grants

    Student entrepreneurs at Harvard have won $50,000 in grants to support further development of innovative ventures in the Harvard College Innovation Challenge.

  • Chen wins Lemelson-MIT Prize

    Graduate student Alice A. Chen received the prestigious $30,000 Lemelson-MIT Student Prize on Wednesday (March 9) for her innovative applications of microtechnology to study human health and disease.

  • Harvard Medical School researchers crawl a neural network

    Scientists can finally look at circuits in the brain in all of their complexity. How the mind works is one of the greatest mysteries in nature, and this research presents a new and powerful way for us to explore that mystery.

  • URES taps three SEAS grad students

    Three technology proposals from the Harvard School of Engineering and Applied Sciences (SEAS) have been selected for presentation at the University Research and Entrepreneurship Symposium (URES).

  • Leslie Valiant wins Turing Award

    The Association for Computing Machinery (ACM) today (March 9) named Leslie G. Valiant the winner of the 2010 ACM A.M. Turing Award for his fundamental contributions to the development of computational learning theory and to the broader theory of computer science.

  • The impact of plate tectonics

    A new research paper by Harvard geophysicists Brendan Meade and Jack Love-less says that the earth sciences principle of plate tectonics is applicable on a continental scale.

  • Cultivating trouble

    Only 39 percent of the nearly 10,000 North American plant species threatened with extinction are being maintained in collections, according to the first comprehensive listing of the threatened plant species in Canada, Mexico, and the United States.

  • Cutting the military’s energy tether

    Fueling America’s war effort is an expensive proposition, costing not only money but lives, since supply convoys are routinely attacked. The constraints imposed by an energy-hungry military prompted the Defense Department to investigate conservation techniques.

  • America’s Eden that wasn’t

    A new history of science course on the environment moves past the fictions of an unspoiled earlier time of discovery and settlement.

  • Chips, efficient and fast

    Professor Gu-Yeon Wei explores energy-efficient computing devices that are fast but draw minimal power.

  • Matching supply, demand

    Harvard graduate student Wonyoung Kim has developed and demonstrated a new device with the potential to reduce the power usage of modern processing chips.

  • Brenner awarded Ledlie Prize

    Michael Brenner, Glover Professor of Applied Mathematics and Applied Physics at the Harvard School of Engineering and Applied Sciences, has been awarded the George Ledlie Prize by the President and Fellows of Harvard College.

  • Mapping the Human Genome: Ten Years After

    On February 15, 2001, a decade ago, the first draft sequence and analysis of the human genome—the blue print for a human being—was published in the journal Nature. On the tenth anniversary of that transformative moment, Harvard hosted an interdisciplinary, multi-institutional forum on the genome project’s origins, promise, and significance to society.

  • Deep water, deep trouble

    Two insiders view the BP oil spill as a failure of management — but also as an incident that revealed deep regulatory and safety failures.

  • Cells flow like glass, study finds

    Harvard-led research has found that migrating tissue flows very much like colloidal glass. The research advances scientists’ understanding of wound healing, cancer metastasis, and embryonic development.

  • The map of us

    To mark the 10th anniversary of the publication of the Human Genome Map, Harvard President Drew Faust will host a panel discussion on the project next week (Feb. 22) in Sanders Theatre.

  • What ultra-tiny nanocircuits can do

    Engineers and scientists collaborating at Harvard University and the MITRE Corp. have developed and demonstrated the world’s first programmable nanoprocessor.

  • Clues in clay

    Research by physicists from Harvard’s School of Engineering and Applied Sciences, Princeton, and Brandeis shows that clay vesicles provide an ideal container for the compartmentalization of complex organic molecules. The discovery opens the possibility that primitive cells may have formed inside inorganic clay microcompartments.

  • Solar’s time still on horizon

    Bruce Sohn, president of the power company First Solar, says that reducing the cost of solar energy is on the horizon, but solar power has to grow dramatically if it is to replace fossil fuels.
