  • Sickly sweet

    A long-term study, led by the Harvard T.H. Chan School of Public Health, found that the more sugar-sweetened beverages people consumed, the greater their risk of premature death — particularly death from cardiovascular disease, and to a lesser extent from cancer.

  • First-time opioid prescriptions drop by 50 percent

    Based on a Harvard study, the monthly rate of first-time opioid prescriptions dropped by more than half between 2012 and 2017. A new concern now is whether some patients are getting less-than-adequate treatment for their pain.

  • Longevity and anti-aging research: ‘Prime time for an impact on the globe’

    Research into extending humanity’s healthy lifespan has been progressing rapidly in recent years. In February, a group of aging and longevity scientists founded a nonprofit to foster the work and serve as a resource for governments and businesses looking to understand the potentially far-reaching implications of a population that lives significantly longer, healthier lives.

  • Study identifies gene regions associated with sleep duration

    Scientists from Massachusetts General Hospital and the University of Exeter Medical School have identified another 76 gene regions associated with sleep duration. Their findings may underpin future investigations into disordered sleep and understanding individual set points for how much is enough.

  • Ending HIV transmission by 2030

    Eradicating the remaining pockets of HIV transmission in the U.S. by 2030 will be a challenge for the Trump administration, and depend on local cooperation in reaching high-risk groups with surveillance, prevention, and treatment, according to Harvard HIV/AIDS researcher Max Essex.

  • Harnessing nature to beat cancer

    Every year, more than 18 million people around the world are told, “You have cancer.” In the U.S., nearly half of all men and more than one-third of women will…

  • The algorithm will see you now

    AI is coming to a hospital near you — but it may be in the world’s remote regions that it could impact patients most. However, experts gathered at Harvard said its potential will not be realized unless it is deployed as part of broader health care solutions, not simply as a tool in search of problems.

  • Medicating mosquitoes to fight malaria

    Considering a new strategy for malaria control that complements existing insecticide-treated bed nets, a Harvard-led study found that mosquitoes landing on surfaces coated with the antimalarial drug atovaquone were blocked from developing the parasite that causes the disease.

  • Overlapping surgeries mostly safe

    Overlapping surgeries, in which more than one doctor performs sequential surgeries in different operating rooms, have raised concerns about potential adverse outcomes — but a new analysis shows they carry no greater risk for low-risk, noncardiac patients.

  • Quitting smoking may reduce risk of rheumatoid arthritis

    Analysis of data from the Nurses’ Health studies shows quitting smoking may reduce the risk of the severest form of rheumatoid arthritis.

  • Gene therapy was a ‘last shot’

    Three years after undergoing gene therapy at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center to treat a life-threatening immune disorder, an Ohio college student is no longer thinking about his own “last shot” for health, but rather about medical school and “giving back.”

  • Exercise, fasting help cells shed defective proteins

    A new study from the Blavatnik Institute finds that intense exercise and fasting activate hormones that boost cells’ capacity to dispose of defective proteins, which clog up the cell, interfere with its functions, and, over time, precipitate diseases including neurodegenerative conditions such as ALS and Alzheimer’s.

  • Drop and give me 40

    Harvard researchers have found that the number of pushups middle-aged men can do may be a useful, no-cost tool to help clinicians assess cardiovascular disease risk during routine examinations.

  • Finding our genomic clockwork

    Harvard researchers have discovered that a novel biomarker of aging in rDNA can accurately determine an individual’s chronological and biological age. The biomarker opens new opportunities for monitoring responses to interventions and lifestyle choices.

  • Platelet ‘decoys’ outsmart both clots and cancer

    A team of researchers at the Wyss Institute at Harvard University and several collaborating institutions has created a drug-free, reversible antiplatelet therapy that uses deactivated “decoy” platelets to reduce the risk of blood clots and potentially prevent cancer metastasis.

  • Interaction between immune factors can trigger cancer

    Harvard researchers found that interaction between immune factors triggers cancer-promoting chronic inflammation, setting the stage for the development of skin cancer associated with chronic dermatitis and colorectal cancer in patients with colitis.

  • Engineered mini-kidneys come of age

    By exposing stem cell-derived kidney organoids to fluidic shear stress, A team of Harvard researchers has significantly expanded the organoids’ vascular networks and improved the maturation of kidney compartments.

  • Microneedle pill takes the sting out of insulin

    A team of investigators from Harvard-affiliated Brigham and Women’s Hospital, MIT, and Novo Nordisk has developed a microneedle pill that can deliver an oral formulation of insulin that can be swallowed rather than injected.

  • Toward safer bone-marrow transplants

    The combination of the antibody CD117 and the drug saporin selectively targets blood stem cells, making transplantation safer by limiting collateral damage caused by the current standard of treatment, chemotherapy, and radiation.

  • The science, business of aging

    A half-day conference at Harvard Business School examined the growing promise of research on aging and the potential of now-experimental interventions to one day ease the burdens of infirmity.

  • A gathering to battle cancer

    Amid projections that global cancer rates will skyrocket, researchers from around the country gathered at Harvard Monday to share their latest findings and to launch a center whose aim is to boost cancer early detection and prevention.

  • Spending dips on health care for the Medicare elderly

    Health care spending among the Medicare population age 65 and older has slowed dramatically since 2005, and as much as half of that reduction can be attributed to reduced spending on cardiovascular disease, a new Harvard study has found.
