  • So long, snout

    New research shows that bird beaks are the result of skeletal changes controlled by two genetic pathways, shedding light on the origins of one of nature’s most efficient tools.

  • Asthma cells scramble like ‘there’s a fire drill’

    Until now, scientists thought that epithelial cells — which line not only the lung’s airways but major cavities of the body and most organs — just sat there motionless. A Harvard study shows that in asthma the opposite is true.

  • How new biosensors turn E. coli into something valuable

    New biosensors developed by Wyss Institute core faculty member George Church enable complex genetic reprogramming of common bacteria like E. coli and could be leveraged for sustainable biomanufacturing, using the metabolic processes of bacterial cells to generate valuable chemicals and fuels.

  • Potential treatment for muscular dystrophy

    Harvard researchers report that by identifying and mimicking important developmental cues, they have been able to drive cells to grow into muscle fibers capable of contracting in a dish and multiplying in large numbers. This new method of producing muscle cells could offer a better model for studying muscle diseases, such as muscular dystrophy, and for testing potential treatments.

  • New hope in old viruses

    Harvard Stem Cell Institute researchers at Massachusetts Eye and Ear have reconstructed an ancient virus that is highly effective at delivering gene therapies to the liver, muscle, and retina.

  • Inadequate hydration can lead to impaired cognitive, emotional function

    Drinking enough water is essential for physiological processes such as circulation, metabolism, temperature regulation, and waste removal. More than half of all children and adolescents in the United States are under-hydrated — probably because they’re not drinking enough water, according to the first national study of its kind from the Harvard T.H. Chan School of Public Health.

  • Expanding the brain

    New findings reveal how genomic imprinting can dramatically expand biological diversity, and could have important implications for understanding the brain.

  • Hard-won lizards

    Research on the evolutionary history of the anole lizard became an international adventure for Professor Jonathan Losos.

  • Recurrent ovarian cancer patients may have hope

    Harvard researchers have found a gene therapy that delivers a protein that suppresses the development of female reproductive organs. This new treatment could improve the survival of patients with ovarian cancer that has recurred after chemotherapy. Recurrence happens 70 percent of the time and is invariably fatal.

  • Zebrafish reveal drugs that may improve bone marrow transplant

    Using large-scale zebrafish drug-screening models, Harvard Stem Cell Institute researchers at Boston Children’s Hospital have identified a potent group of chemicals that helps bone marrow transplants engraft, or “take.”

  • Keeping adults in the game

    In response to a recent poll that found most adults who played sports when they were younger stopped doing so as they aged, a panel of experts convened at the Harvard T.H. Chan School of Public Health explored how to keep adults in the game.

  • Self-diagnosis on Internet not always good practice

    Online symptom checkers can often be wrong in both diagnosis and triage advice, but they still may be useful alternatives to phone triage services and Internet searches.

  • Diagnosing Ebola in minutes

    A new test can accurately diagnose the Ebola virus disease within minutes at the point of care.

  • Alone with evolution

    Efforts by Harvard faculty to understand island evolution form the centerpiece of a new exhibition at the Harvard Museum of Natural History.

  • Sequencing Ebola’s secrets

    A global team from Harvard University, the Broad Institute, the U.S. Centers for Disease Control, and other institutions sequenced more than 200 additional Ebola samples to capture the fullest picture yet of how the virus is transmitted and changes over a long-term outbreak.

  • Another turning point for Obamacare

    Panelists at the Harvard Chan School weighed the possible implications of the latest Supreme Court challenge to the Affordable Care Act.

  • Coordinating against malaria

    Leaders in the global fight to eradicate malaria are at Harvard this week for a leadership training course that explores many facets of the scientific underpinnings of the effort to eradicate malaria from the planet.

  • Cracking the egg

    Mary Caswell Stoddard of Harvard’s Society of Fellows is bringing an interdisciplinary approach to her study of bird eggs.

  • Vital genes in fat production found

    Scientists at Harvard Stem Cell Institute have found a way to both make more energy-burning human brown fat cells and make the cells themselves more active, a discovery that could have therapeutic potential for diabetes, obesity, and other metabolic diseases.

  • A dearth of nutrition in school lunches

    About 200 people interested in improving the quality of meals served in America’s public schools gathered at Harvard to discuss topics ranging from getting wholesome food into schools to institutional barriers.

  • Confronting the creep of opioid abuse

    Specialists in care and policy came together at the Harvard Chan School to trade ideas on combating opioid abuse.

  • Changing the way genomes work

    In the Wyss Institute’s inaugural podcast “Disruptive,” host Terrence McNally spoke with Pamela Silver and George Church about today’s breakthroughs in technology and modifications to an organism’s genome that can be conducted more cheaply, efficiently, and effectively than ever before.

  • Leaving a beautiful scar

    Feature on surgeon and violinist Terry Buchmiller as part of the Practice series.

  • At Medical School, a late bloomer

    Afamefuna Nduaguba, a Nigerian immigrant, overcame early struggles at Roxbury Community College to gain a bachelor’s degree from the University of Massachusetts, Boston, and now an M.D. from Harvard Medical School.

  • Improved accuracy in genome editing

    A team of scientists has engineered a form of the genome-editing protein Cas9 that can be controlled by a small molecule and offers improved DNA specificity.

  • Creatures of habit

    The motor cortex is critical to learn new skills, but may not be needed to perform them, a new Harvard study says.

  • ‘New clarity’ against Alzheimer’s

    Rudolph Tanzi of Harvard Medical School, recently named to Time’s list of the most influential people in the world, talks about the promising future of Alzheimer’s research.

  • Meditation may relieve IBS and IBD

    A small pilot study by Harvard-affiliated researchers finds symptom improvement and changes in expression of inflammation-associated genes in irritable bowel syndrome and inflammatory bowel disease patients who practice the relaxation response.

  • Insight into seeing

    Harvard-affiliated researchers have been able to make a comparison of neurons in optic nerves to learn more about why some regenerate and others don’t.

  • Rapid evolution

    As part of the Harvard Horizons Symposium, Ph.D. candidate Shane Campbell-Staton will discuss his work with the green anole lizard, which corroborates the fact that rapid evolutionary responses can be viewed in real time.
