Scientists visualized the brain’s lymphatic waste-removal structures non-invasively and in near-real-time for the first time. Using the new MRI technique to study these little-understood brain structures could aid research on neurodegenerative diseases such as Alzheimer’s.
Scientists grew macrophage cells in a lab, finding that they functioned indistinguishably from cells grown in the body when transplanted. Macrophages are important immune cells that could be used to fight infections and cancer, and this is the first time they’ve been successfully grown in a lab.
Researchers concluded the eruption of the Hunga Tonga-Hunga Ha'apai volcano in January will have a smaller global cooling effect than previously thought. Sulfur dioxide emitted from volcanoes can cool the global climate, but the Tonga volcano’s location limits the spread of this effect.
