All Science & Tech

  • Next big thing: Improved tiny tweezers

    Harvard School of Engineering and Applied Sciences have developed a new device that creates strong forces more efficiently than traditional optical tweezers and eliminates a problem that caused earlier setups to overheat.

  • The return to recycling

    Recycling was the norm before the Industrial Revolution’s creation of cheap consumer goods started to produce what eventually became the throwaway society, according to Susan Strasser, author of the book “Waste and Want: A Social History of Trash.”

  • He blended it with science

    Harvard professor and current Radcliffe fellow Michael Brenner explores the evolution of his wildly popular cooking course.

  • Developing fast, but sustainably

    The Harvard Sustainability Science Program marked the beginning of its third phase Sept. 19 with a forum on issues facing the rapidly industrializing major nations of China, Brazil, and India.

  • Following path of genetic footprint

    An international team of researchers studying DNA patterns from modern and archaic humans has found that the Denisovans, a recently discovered hominin group, contributed genes to several populations in Asia and that modern humans settled Asia in more than one migration.

  • Scientific research, artfully shown

    Researchers at the Harvard-Smithsonian Center for Astrophysics have embarked on an exploration unusual for space scientists — one involving art. A project probes how the presentation of images of space affects viewers’ appreciation and understanding of what’s happening in the pictures.

  • Plant offers slick strategy

    Adopting the pitcher plant’s slick strategy, a group of applied scientists at Harvard have created a material that repels just about any type of liquid, including blood and oil, and does so even under harsh conditions like high pressure and freezing temperatures.

  • Intuitive? Try God

    Harvard researchers exploring the roots of religion have found that intuitive thinking leads to belief in God, while more reflective thinking points toward atheism.

  • Surgical precision

    In ES 227, “Medical Device Design,” SEAS students are given the opportunity to solve practical problems in a hospital setting, trying out the tools, learning about their use in real-world situations, and, in some cases, even sitting in on surgical procedures.

  • Data may not compute

    The Dataverse Network Project, spearheaded by Harvard’s Institute for Quantitative Social Science, provides archival storage for research projects whose records are on outmoded technology formats.

  • Guarding the forests

    The regeneration of the region’s forests during the last 150 years is an environmental gift that New Englanders shouldn’t squander with thoughtless development, the director of the Harvard Forest said in a talk at the Harvard Museum of Natural History.

  • What makes AA work?

    Among the many ways that participation in Alcoholics Anonymous (AA) helps its members stay sober, two appear to be most important — spending more time with individuals who support efforts toward sobriety and increased confidence in the ability to maintain abstinence in social situations.

  • When old stars slow down

    New research from the Harvard-Smithsonian Center for Astrophysics shows that some old stars might be held up by their rapid spins, and when they slow down, they explode as supernovae. Thousands of these “time bombs” could be scattered throughout our Galaxy.

  • From a flat mirror, designer light

    Using a new technique, researchers at the Harvard School of Engineering and Applied Sciences have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction.

  • With the Earth as teacher

    Students in Earth and Planetary Sciences kicked off their academic year early, spending a late-August week in paradise, observing Hawaii’s volcanoes, green and black sand beaches, and overarching geologic splendor.

  • Wake-up call

    Insomnia is costing the average U.S. worker 11.3 days, or $2,280, in lost productivity every year, according to a study led by Ronald Kessler of Harvard Medical School.

  • Connecting with freshmen

    Harvard College freshmen got their first taste Aug. 26 of the world of ideas awaiting them over the next four years in a talk by Professor Nicholas Christakis, who delivered the 2011 Opening Days Lecture, “Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives.”

  • 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.

  • What’s in a liquid

    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.
