  • 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.

  • 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.

  • 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.
