U.S. Explores New Methods for Lunar Ice Detection Using Synchrotron X-ray Microtomography and Seismic Models

On July 31, researchers at Lawrence Berkeley National Laboratory, in collaboration with scientists from the University of Maryland and the University of Hawaii, proposed a new method for locating subsurface ice deposits on the Moon using seismic waves. The findings, published in the journal Science Advances, are expected to provide a reference for interpreting detection data and locating water resources in future lunar landing missions. The research focuses on how subsurface lunar materials respond to seismic waves. The team developed computational models to predict the behavior of lunar subsurface media of varying compositions under seismic wave excitation. Experimental results showed differences in seismic response between ice-bearing and dry rocks, indicating that seismological methods have the potential to identify ice layers buried beneath lunar regolith and rock.

Russia's Vector Research Center Proposes Quantum Dots for Boron Delivery in Neutron Capture Therapy

Russia's Vector Research Center has proposed using quantum dots as targeted boron delivery systems in boron neutron capture therapy (BNCT) to explore more precise approaches to tumor treatment. Yuri Tumanov, the center's chief researcher, presented this research progress at a conference on engineering biology and biopharmaceuticals. Boron neutron capture therapy is a cancer treatment method that combines boron-containing drugs with neutron irradiation. The basic concept involves first allowing boron-containing drugs to accumulate in tumor cells, then subjecting the patient to neutron irradiation, which triggers a nuclear reaction that releases energy concentrated within boron-containing cancer cells, thereby destroying tumor cells. How to construct boron delivery systems that are low-toxicity, highly efficient, and capable of participating in targeted tumor destruction remains one of the key challenges in this field...

Czech research team develops minimally invasive radiocarbon dating sampling method to aid dating of prehistoric rock art

A research team at the Czech Radiocarbon Laboratory (CRL) of the Nuclear Physics Institute of the Czech Academy of Sciences has developed a minimally invasive sampling method for dating carbon-based rock art, enabling the acquisition of materials needed for radiocarbon dating with virtually no damage to the rock art's appearance. After sampling, the outline of the rock art remains intact, with only a slight lightening of color in the sampled area. This method provides a new technical pathway for dating cave paintings of historical value. In the past, sampling of cave paintings was often strictly restricted for heritage conservation reasons, which also hindered related chronological determination efforts. The new method, through a gentler sampling approach, enhances the feasibility of dating carbon-based rock art while maximizing the preservation of its scientific and cultural value...
