CAMBRIDGE, Mass. (AP) — Harvard University professor Alberto Ascherio’s research is literally frozen. Collected from millions of U.S. soldiers over two decades using millions of dollars from taxpayers, the epidemiology and nutrition scientist has blood samples stored in liquid nitrogen freezers within the university’s T.H. Chan School of Public Health. The samples are key to his award-winning research, which seeks a cure to multiple sclerosis and other neurodegenerative diseases. But for months, Ascherio has been unable to work with the samples because he lost $7 million in federal research funding, a casualty of Harvard’s fight with the Trump administration.“It’s like…

Kennedy Jr., who blames them for causing…

Facebook Tweet Email Link In a major new finding almost a decade in the making, researchers at Harvard Medical School say they’ve found a key that may unlock many of the mysteries of Alzheimer’s disease and brain aging — the humble metal lithium. Lithium is best known to medicine as a mood stabilizer given to people who have bipolar disorder and depression. It was approved by the US Food and Drug Administration in 1970, but it was used by doctors to treat mood disorders for nearly a century beforehand. Now, for the first time, researchers have shown that lithium is…

The National Highway Traffic Safety Administration has given Zoox an exemption to demonstrate its custom-built robotaxis on public roads and closed a related investigation into whether the Amazon-owned company had sidestepped federal regulations. The decision, which was announced Wednesday, clears up a long-standing debate over whether Zoox’s custom-built autonomous vehicles complied with federal motor vehicle safety standards, which place requirements on vehicles such as having a steering wheel and pedals. Zoox had argued that it did and announced in July 2022 that it had self-certified; NHTSA balked. The agency opened an investigation in March 2023 to look into the matter,…
