From a Harvard news online release:
“This study identifies a new molecular connection between exercise and inflammation that takes place in the bone marrow and highlights a previously unappreciated role of leptin in exercise-mediated cardiovascular protection,” said Michelle Olive, program officer at the National Heart, Lung, and Blood Institute Division of Cardiovascular Sciences. “This work adds a new piece to the puzzle of how sedentary lifestyles affect cardiovascular health and underscores the importance of following physical-activity guidelines.”
Scientists at Harvard-affiliated Massachusetts General Hospital (MGH) have identified a previously unknown biological pathway that promotes chronic inflammation and may help explain why sedentary people have an increased risk for heart disease and strokes.
In a study to be published in the November issue of Nature Medicine, MGH scientists and colleagues at several other institutions found that regular exercise blocks this pathway. This discovery could aid the development of new therapies to prevent cardiovascular disease.

This week our correspondent joined Emmanuel Macron on his visit to China. The French president is stretching his diplomatic wings, and has some striking views about Europe’s place in the world. The state of Texas has been reliably Republican for decades, but its demographics are changing; could it at last turn blue? And how Japan is dealing with its epidemic of public-transport groping.
There was a massive shift in Roman residents’ ancestry, the researchers found, but that ancestry came primarily from the Eastern Mediterranean and Near East, possibly because of denser populations there relative to the Roman Empire’s western reaches in Europe and Africa.
Recent polls in early voting states show Pete Buttigieg’s popularity surging among Democratic voters. The mayor of South Bend, Indiana, is now in the top tier of candidates vying for the chance to challenge President Trump in the 2020 presidential election. But with that growing support comes rising scrutiny. Judy Woodruff talks to Buttigieg about health care, taxes and uniting a divided country.
Including beautiful full-color reproductions of the artworks, A Month in Siena is about what occurred between Matar, those paintings, and the city. That month would be an extraordinary period in the writer’s life: an exploration of how art can console and disturb in equal measure, as well as an intimate encounter with a city and its inhabitants. This is a gorgeous meditation on how centuries-old art can illuminate our own inner landscape—current relationships, long-lasting love, grief, intimacy, and solitude—and shed further light on the present world around us.
