An analysis of data from two long-term epidemiologic studies has found that regular use of aspirin significantly reduces the overall risk of cancer, an effect that primarily reflects a lower risk of colorectal cancer and other tumors of the gastrointestinal tract.
A new study out of Harvard Medical School and the National Running Center at Harvard-affiliated Spaulding Rehabilitation Hospital examined why runners get injured so often.
Children with acute lymphoblastic leukemia who live in high-poverty areas are substantially more likely to suffer early relapse than other patients, according to a new study.
National health insurance is just a first step to solving the divide between America’s well-off healthy and its poorer, sicker people, Harvard analysts say.
Katherine Gregory, a nurse scientist at Brigham and Women’s Hospital, searched for an answer to the mystery of necrotizing enterocolitis (NEC), a sometimes fatal infectious disease of the newborn gut affecting preterm infants.
A state-of-the-art microscope built by Harvard researchers will allow scientists to capture 3-D images of all the neural activity in the brains of tiny, transparent C. elegans worms as they crawl.
The Gazette spoke with Michael Charness, chief of staff for the Harvard-affiliated VA Boston Healthcare System, about the CDC’s recommendations to sexually active woman of childbearing age: either use birth control or don’t drink.
Rett syndrome is a relatively common neurodevelopmental disorder, the second most common cause of intellectual disability in girls after Down syndrome. Building on 2004 findings, Harvard researchers identified a faulty signaling pathway that, when corrected in mice, improves the symptoms of Rett syndrome.
Massachusetts General Hospital researchers are working on a topical treatment that may be available for those with seborrheic keratosis (SK), or liver spots. SKs vary in color from tan to black, can be flat or raised, and range in size from quite small to an inch or more across.
Researchers have found that cancer begins after activation of an oncogene or loss of a tumor suppressor, and involves a change that takes a single cell back to a stem cell state. They believe this model may apply not only to melanoma, but to most if not all cancers.
Researchers at MIT’s David H. Koch Institute for Integrative Cancer Research, in collaboration with scientists at the Harvard Stem Cell Institute and several other institutions, have developed an implantable device that in mice shielded insulin-producing beta cells from immune system attack for six months — a substantial proportion of life span.
Harvard’s John A. Paulson School of Engineering and Applied Sciences, Center for Brain Science, and Department of Molecular and Cellular Biology have been awarded more than $28 million to develop advanced machine learning algorithms by pushing the frontiers of neuroscience.
A Graduate School of Education alumna brings her family history into the dance studio as she teaches children with disabilities the art of movement and the rewards they can reap.
Oral contraceptives taken just before or during pregnancy do not increase the risk of birth defects, according to a new study by researchers from the Harvard T.H. Chan School of Public Health and the Statens Serum Institut in Denmark.
A research team at the Wyss Institute has developed a novel microfluidic device in which blood flows through a lifelike network of small “vessels.” Using automated pressure sensors and a proprietary algorithm, the data acquired is analyzed in real time and precisely predicts when a certain blood sample will obstruct the blood vessel network.
Scientists gave little thought to the neurological effects of dance until relatively recently, when researchers began to investigate the complex mental coordination that dance requires.
A multicomponent, microfluidic small airway-on-a-chip model provides new opportunities to study human lung inflammatory disorders such as chronic obstructive pulmonary disease (COPD) and asthma, and to test preclinical drug candidates outside the human body.
Scientists identify a molecular key that helps cells maintain identity and prevents the conversion of adult cells into induced pluripotent stem cells — a process that would require a cell to “forget” its identity before assuming a new one.
Using a visual test that is known to prompt different reactions in autistic and normal brains, Harvard researchers have shown that those differences were associated with a breakdown in the signaling pathway used by one of the brain’s chief inhibitory neurotransmitters.
A study from Brigham and Women’s Hospital offers a new view of how cancer cells extend their reach, co-opting and transforming normal cells through “metastatic hijacking.” The researchers also found that in preclinical models, pharmacological intervention can prevent this from occurring.
In a new study, the Wyss Institute’s human-gut-on-a-chip technology is used to co-culture gut microbiome and human intestinal cells, which could spur innovation of novel therapies for inflammatory bowel diseases.
Frank Hu, a professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health and the principal investigator of the diabetes component of the landmark Nurses’ Health Study, responded to the latest Center for Disease Control and Prevention findings in an interview with the Gazette.
The Harvard Museum of Natural History opens a new marine life gallery, which uses the seas off New England as a lens for learning about marine life around the world.
