  • Aquatic genome captures foreign DNA

    Long viewed as straitlaced spinsters, sexless freshwater invertebrate animals known as bdelloid rotifers may actually be far more promiscuous than anyone had imagined: Scientists at Harvard University have found that the genomes of these common creatures are chock-full of DNA from plants, fungi, bacteria, and animals.

  • Protective mechanism fails when obesity sets in

    Reporting in the journal Cell Metabolism, researchers from the Harvard School of Public Health (HSPH) said they have shown for the first time that fat-storing cells, or adipocytes, contain a protective anti-inflammatory immune mechanism that prevents the cells from overreacting to inflammation-causing stimuli, such as fatty acids in the diet.

  • Cluzel named professor of molecular and cellular biology, applied physics

  • HSPH student takes aim at AIDS with statistics

    Bethany Hedt has always been in love with numbers. Her challenge has been finding a way to feed that love while fulfilling an equally strong drive to help the people around her.

  • John Passanese eyes the alternatives

    Yoga is a popular activity for many Harvard undergraduates looking to stay fit or reduce stress. For John Passanese, a Lowell House senior, yoga has additional importance — it can be an excellent tool for managing chronic pain. For more than 20 years, Passanese’s mother has suffered from multiple sclerosis (MS), a neurodegenerative disease that attacks the body’s central nervous system. MS can cause a range of debilitating symptoms, including cognitive disabilities, paralysis, loss of vision, and chronic pain. There is no known cure.

  • Experiment advances cell reprogramming understanding

    The announcement last year by scientists in Japan, at the Harvard Stem Cell Institute (HSCI), and at the Whitehead Institute that they had each — independently — coaxed adult cells into reverting to an embryonic stem cell-like state was arguably the biggest news in developmental biology since the cloning of Dolly the ewe.

  • Intestinal bacteria promote and prevent inflammatory bowel disease

    Scientists search for drug candidates in some very unlikely places. Not only do they churn out synthetic compounds in industrial-scale laboratories, but they also scour coral reefs and scrape tree bark in the hope of stumbling upon an unsuspecting molecule that just might turn into next year’s big block buster. But one region that scientists have not been searching is their guts. Literally.

  • Genomic analysis gives new insights into cellular reprogramming

    A cross-disciplinary team of Harvard University, Whitehead Institute, and Broad Institute researchers has uncovered significant new information about the molecular changes that underlie the process by which adult cells can…

  • Recent longitudinal study: Smoking is addictive, quitting is contagious

    Over the past 30 years, the number of smokers in the United States has steadily decreased — a tribute to the efforts of public-health workers everywhere. And while this fact is indisputable, less obvious are the social and cultural forces that lead an individual to kick the habit.

  • Undergrads volunteer for Nalgene bottle BPA study

    For a while last month, whenever Scott Elfenbein ’11 was thirsty he’d take a pull or two from a Nalgene bottle. But Elfenbein was quaffing from Nalgene for science, not for convenience. He was one of about 80 Harvard College students who volunteered for a two-week April study intended to track levels of bisphenol A in their bodies.
