The Scientist consulted Gabriela Popescu, PhD, a professor in the Department of Biochemistry in the Jacobs School of Medicine and Biomedical Sciences, about research published this week in Nature. The research suggests injecting cerebrospinal fluid from younger mice into older mice can rejuvenate the memory of the recipients under specific conditions. Popescu said the paper’s observations are interesting and “a good fact to know,” but she has reservations. “I think it’s wrong to sell science this way,” said Popescu, referring to studies that imply there’s a straightforward way to reverse aging, memory loss or other common sources of health-related anxiety.
