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 studied damage to minerals in the Chelyabinsk meteorite to identify and date impacts in its history. The method they used could make dating asteroid collisions more accurate and shed light on impacts in the distant past that formed planets.
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.
NASA’s Curiosity rover captured a striking image of a 1-centimeter concretion formed by minerals left behind from ancient groundwater. The image is a merging of separate shots performed by Curiosity which allows tiny objects to stay in focus.
Researchers successfully used bovine lactoferrin, a protein in cow’s milk, to inhibit Covid-19 in lab conditions. The researchers believe treatments based on lactoferrin could be effective against potential future strains as well.
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.
NASA launched its latest Geostationary Operational Environmental Satellite-T aboard an Atlas V 541 rocket. The GOES-T weather satellite will help meteorologists predict weather events including floods and hurricanes in the western United States, Mexico, and Central America.
