Modularity is taking off in more ways than one in space exploration. The design of the upcoming "Lunar Gateway" space station is supposed to be modular, with different modules being supplied by different organizations. In an effort to extend that thinking down to rovers on the ground, researchers at Germany's space agency (DLR), developed an architecture where a single, modular rover could be responsible for both exploration and carrying payloads around the moon or Mars. The study is published in Acta Astronautica.
Faulty versions of the LMNA gene can cause a wide range of health problems, including heart muscle disease (dilated cardiomyopathy) and muscle weakness (muscular dystrophies). Many of these diseases are caused by single-point mutations, which are changes to one DNA "letter" (base). Treatments include physical therapy and lifelong medication, but there are currently no cures. That could change following the work of a team of scientists who have developed and successfully tested a gene editing technique to correct the underlying genetic mutations.
