In an Annenberg Public Policy Center white paper, biostatistician Jeffrey Morris of the University of Pennsylvania's Perelman School of Medicine analyzes the U.S. vaccine safety monitoring system and suggests how its components, including VAERS, can be improved.

Researchers at the University of Pennsylvania and University of Michigan have created the world’s smallest fully programmable, autonomous robots: microscopic swimming machines that can independently sense and respond to their surroundings, operate for months and cost just a penny each. Barely visible to the naked eye, the robots are smaller than grains of salt and could advance medicine, manufacturing and more.

Monoterpenoids are important plant-derived compounds widely used in fragrances, nutraceuticals, and medicinal applications. 

To address the global environmental and climate crisis and advance the UN SDGs, it is essential to fully leverage Earth observations (EO) through the integration of atmospheric, hydrological, cryospheric, lithospheric, ecological, and socio-economic data. Based on discussions from the 2023 “Towards Global Earth Observatory” workshop, this paper highlights the fragmented nature of current EO and data repositories and emphasizes the need for a more coordinated global Ground-Based Earth Observatory (GGBEO). We summarize the status of key in-situ and ground-based remote sensing systems and outline the actions required to build an integrated GGBEO with interoperable data repositories, unified observation networks, and sustainable long-term support.
