A new study has uncovered how tiny differences in boron atoms can help scientists better predict the long-term behavior of glass used to store hazardous waste. The findings, published in Environmental and Biogeochemical Processes, could improve forecasts of how radioactive materials are released from storage over thousands of years. Glass is often used to immobilize contaminants such as radionuclides and heavy metals, locking them safely inside a stable structure. However, when groundwater seeps into disposal sites, the glass can gradually dissolve. Understanding this process is crucial for ensuring the safety of geological ...

Mediterranean vineyards face a growing threat from heavy rains and soil degradation that strip away fertile topsoil. New research led by scientists at the University of Aveiro, Portugal, shows that adding biochar, a carbon-rich material made from plant waste, can dramatically reduce erosion and improve the soil’s ability to store water. The study, published in Biochar, is among the first to test biochar’s impact on the “soil sponge function” under natural rainfall in sloping Mediterranean vineyards. Over 18 months, researchers used outdoor lysimeters filled with vineyard ...

Manufacturing better batteries, faster electronics, and more effective pharmaceuticals depends on the discovery of new materials and the verification of their quality. Artificial intelligence is helping with the former, with tools that comb through catalogs of materials to quickly tag promising candidates.  But once a material is made, verifying its quality still involves scanning it with specialized instruments to validate its performance — an expensive and time-consuming step that can hold up the development and distribution of new technologies.  Now, a new AI tool developed by MIT ...

Scientists have discovered a method to induce human endothelial cells from a small biopsy sample to multiply in the laboratory, producing more than enough cells to replace damaged blood vessels or nourish organs for transplantation, according to a preclinical study by Weill Cornell Medicine investigators. Endothelial cells form the inner lining of blood vessels and regulate blood flow, inflammation and healing. Traditional approaches for growing these cells in the lab have yielded only limited numbers before they lose their ability to function. The new method involves treating adult endothelial cells with a small molecule that triggers the hibernating cells to wake up and divide hundreds of ...
