Juno Maps Water Ice Across Northern Ganymede

Jupiter’s moon Ganymede is the largest planetary satellite in the solar system. It’s also one of the most intriguing: Ganymede is the only moon with its own magnetic field, it is the most differentiated of all moons, and it likely possesses a subsurface ocean of liquid water. It was studied by the early […]

Marie Tharp’s groundbreaking maps brought the seafloor to the world

Walk the halls of an academic earth sciences department, and you’ll likely find displayed on a wall somewhere a strikingly beautiful map of the world’s ocean floors. Completed in 1977, the map represents the culmination of the unlikely, and underappreciated, career of Marie Tharp. Her three decades of work as a geologist and cartographer at […]

New migration maps serve as tools to help big game in West

Credit: CC0 Public Domain The life-or-death journey made by mule deer during the second-longest big game migration in North America came down to their ability to squeeze through a fence—a discovery made by scientists using wildlife GPS tracking techniques to map animal migrations in the West in unprecedented detail. The resulting atlas of migration corridors […]

Near-atomic ‘maps’ reveal structure for maintaining pH balance in cells — ScienceDaily

For the first time, scientists have visualized a new class of molecular gates that maintain pH balance within brain cells, a critical function that keeps cells alive and helps prevent stroke and other brain injuries. These gates, called proton-activated chloride channels (PAC), nest within cell membranes and regulate the passage of small molecules called chloride […]
