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.

AIP’s 2026 Karl Taylor Compton Medal for leadership in physics is being awarded to Professor John Holdren of Harvard University and former Chief Science & Technology Advisor to President Obama. Named after prominent physicist Karl Taylor Compton, the medal is presented by AIP every two years to a highly a distinguished physicist who has made outstanding contributions to physics through exceptional statesmanship in science. Holdren was chosen by the selection committee “for his scientific leadership in engaging the public and promoting sound governmental policies and key international agreements.”

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.

Scientists at Aarhus University have developed nanomotors inspired by the bacterium Listeria monocytogenes and placed them inside artificial cells. The nanomotors drive the formation of internal protein networks resembling a cytoskeleton, giving artificial cells a life-like function previously seen only in living cells and marking a step toward self-organizing synthetic systems.

In a newly published review, Professor Xiao-Jun Huang's team at Peking University People's Hospital explore how haploidentical hematopoietic stem cell transplantation (haplo-HSCT), once limited by severe immune complications, has transformed into a routine treatment and a unique platform for studying the restoration of immune homeostasis.
