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.
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.
Washington State University researchers have found a way to modulate a common virus protein to prevent viruses from entering cells where it can cause illness, a discovery that could someday lead to new antiviral treatments. In the fundamental research, reported in the journal Nanoscale, the researchers in the School of Mechanical and Materials Engineering and the Department of Veterinary Microbiology and Pathology were able to find and block an important interaction at the molecular level that allows the herpes virus to enter cells.
