Science News Roundup: London's Science Museum reopens doors; Dwarf planet Ceres is 'ocean world' with salty water deep underground and more

Research published on Monday based on data obtained by NASA's Dawn spacecraft, which flew as close as 22 miles (35 km) from the surface in 2018, provides a new understanding of Ceres, including evidence indicating it remains geologically active with cryovolcanism - volcanoes oozing icy material.

Following is a summary of current science news briefs.

Humanity versus disease showcased as London's Science Museum reopens doors

Exhibits showcasing humanity's battle with the infectious disease will greet visitors recently emerged from coronavirus lockdowns when London's Science Museum re-opens its doors next week after its longest closure since World War II. "Medicine: The Wellcome Galleries" tracks medical advances through history, and its timely displays include an iron lung used for polio patients in the 1950s, an isolation trolley from the 1970s, PPE from the Ebola epidemic, and statistics on the effectiveness of vaccinations.

Dwarf planet Ceres is 'ocean world' with salty water deep underground

Ceres, the largest object in the asteroid belt between Mars and Jupiter, is an "ocean world" with a big reservoir of salty water under its frigid surface, scientists said in findings that raise interest in this dwarf planet as a possible outpost for life. Research published on Monday based on data obtained by NASA's Dawn spacecraft, which flew as close as 22 miles (35 km) from the surface in 2018, provides a new understanding of Ceres, including evidence indicating it remains geologically active with cryovolcanism - volcanoes oozing icy material.
