Call it a new type of precision medicine. A researcher says one day oncologists may be able to write personalized exercise "prescriptions" for cancer patients that suppress tumor growth. Jay Taylor helped develop a mathematical model that attempts to quantify the relationship between exercise, immune function and cancer. The paper looked at models of mice running on wheels to show that increases in exercise intensity and duration decrease the proliferation of malignant cells. According to the paper, the team worked on a mathematical model to describe the transition of natural killer cells from inactive to active states due to exercise-induced...

Hydrogen peroxide (red) emanates from the wound, fading to yellow and green as it dissipates through tissue.Credit: Philipp Niethammer Anyone who has felt the sting as hydrogen peroxide foams and fizzes on a scraped knee knows about the compound's antiseptic properties. But new research suggests that hydrogen peroxide does more than just kill microbes. It may also call for reinforcements, summoning an army of bacteria-fighting cells to cuts and wounds. Punctured skin sets off a chain reaction of chemical signals...

On the day a priest came to her hospital bed and prayed over her withered body, Diana Abad would not have believed good fortune awaited. Or seemed to be, until one day her back started to ache and another day her legs swelled. She had her blood tested and learned her white-cell count was absurdly high. Leukemia, her doctor said. Without a bone-marrow transplant, she would be dead in nine months. David Mason would not have believed in 1990 that by checking a box on a Navy form he would set in motion the chain of events that led him...
