Nanoscale analysis reveals a way to prevent tooth erosion caused by carbonated drinks
Schematic diagram of the workflow. Credit: Biomaterials Research (2024). DOI: 10.34133/bmr.0103 A Korean research team has previously used nanotechnology to visualize and scientifically prove the negative effects of carbonated drinks such as cola on dental health, but now they have demonstrated the effectiveness of these drinks in preventing tooth damage. The mechanism of this method was identified. A team led…

In Patagonia, more snow could prevent glaciers from melting, but only if greenhouse gas emissions are quickly curbed.
Glacier front in southern Patagonia. Credit: Henning Åkesson In an era of declining glaciers, southern Patagonia has managed to retain an astonishing amount of ice. But a new study published in Scientific Reports by INSTAAR postdoctoral researcher Matthias Troch suggests that this protective effect may soon reach its limit. Before making their predictions, Troch and his collaborators looked back. They…

Drug delivery system overcomes circulatory obstacles that prevent gene therapy from reaching its target
Graphical summary. Credit: Cell (2024). DOI: 10.1016/j.cell.2024.07.023 Harnessing the remarkable ability of viruses to deliver gene therapy across previously circulatory obstacles is at the heart of a University of Alberta-led discovery that promises to reinvigorate the field of genetic medicine. John Lewis, an oncologist in the School of Medicine and Dentistry and lead author of the study describing this advance,…

5 surprising ways trees prevent flooding
Credit: Pixabay/CC0 Public Domain When you think of flood protection, you might imagine giant concrete dams, embankments, or glistening dams on the River Thames. But some of the most powerful tools for reducing flood risk are by far the more natural and widely recognized forests and green spaces. Trees provide more than beauty and oxygen. Learn how trees protect us…
