The research, published in Science Advances, is the first to use human data to quantify the speed of the chemical processes leading to the neurodegenerative condition, and could eventually have important implications for how scientists design treatments. It also upends a long-held theory that said the clusters start at a single point and then trigger a chain reaction in other regions, as has been found in mice and was thought true of people too.

Kennedy, speaks to people from a wide spectrum, including coronavirus skeptics, conspiracy enthusiasts, right-wing extremists, religious conservatives, hippies and others gathered under the Victory Column in the city center to hear speeches during a protest against coronavirus-related restrictions and government policy on August 29, 2020 in Berlin, Germany. City authorities had banned the planned protest, citing the flouting of social distancing by participants in a similar march that drew at least 17,000 people a few weeks ago, but a court overturned the ban.
