Survey Analyzes Community Views on Policing in Medford and Somerville
While community residents express some satisfaction, they see inequalities and opportunity for change according to survey by Tufts professor and students

Residents of Medford and Somerville, Massachusetts are somewhat satisfied with policing in their communities-although satisfaction is lower among residents of color-and favor creating civilian review boards, deploying more resources for social services workers to respond to certain types of crises, and eliminating certain policing tactics, according to a survey by a Tufts University professor and a group of student researchers.
“In Medford and Somerville, we found that residents perceive inequalities in how residents are treated based on race and ethnicity,” said Brian Schaffner, Newhouse Professor of Civic Studies at Tufts’ Jonathan M.

LNP Delivers CRISPR Directly to Mouse Liver, Dramatically Cuts Cholesterol Levels for Months
March 2, 2021
Scientists at Tufts University and the Broad Institute of Harvard and MIT have developed a lipid nanoparticle (LNP) technology that can package and deliver CRISPR gene editing machinery specifically to the liver. Their studies in mice demonstrated use of the LNP technology to shuttle CRISPR Cas9 mRNA and guide RNA directly to the liver, to knock down a gene called Angptl3. The strategy resulted in up to 57% reductions in blood cholesterol levels with the effects lasting for several months following a single injection.
“We envision that with this LNP platform in hand, we could now make CRISPR a practical and safe approach to treat a broad spectrum of liver diseases or disorders,” said Zachary Glass, a graduate student in the lab of Qiaobing Xu, PhD, associate professor of biomedical engineering at Tufts’ School of Engineering and corresponding author of the study.

Abstract:
Engineers at Tufts University have created and demonstrated flexible thread-based sensors that can measure movement of the neck, providing data on the direction, angle of rotation and degree of displacement of the head. The discovery raises the potential for thin, inconspicuous tatoo-like patches that could, according to the Tufts team, measure athletic performance, monit
