The idea that Alzheimer’s is caused by brain plaques has long underpinned efforts to treat it—with mostly disappointing results. Now, a growing movement among scientists is challenging basic assumptions about the disease. Is it the start of a new chapter?
Three years into the pandemic, how the virus impacts people’s health can still be mysterious. Why, for example, is it that some end up on ventilators and others get by with a scratchy throat or no symptoms at all? Answers are emerging from scientists who looked beyond the spiky orb to the human side of the equation—and their discoveries are changing the way we think about any infectious disease.
