One delay was attributed to an unspecified medical issue with a crew member, the first such health-related launch postponement for a NASA mission since 1990. As of late Tuesday night the crew, their spacecraft and ground-based launch teams were all ready for liftoff, and “the weather is go for launch,” NASA commercial crew manager Steve Stich told reporters during a pre-flight briefing.For the study — in which 134 people between the age group 19 and 39 participated — researchers used machine learning to generate “brain age” estimates from magnetic resonance imaging (MRI) scans of sleep-deprived people’s brains, which they compared to MRIs of the same people’s brains after a full night’s sleep. “Acute total sleep loss changes brain morphology in an ageing-like direction in young participants and these changes are reversible by recovery sleep,” said Eva-Maria Elmenhorst, from the RWTH Aachen University in Germany, who conducted the study.
