Scientists have unveiled a new blueprint that better captures the richness of human diversity
An international team of scientists mapped nearly the entire human genome for the first time two decades ago, cracking the genetic code of human life. The global effort was a massive scientific feat, and the voyage of discovery helped researchers decode the genetic underpinnings of complex diseases such as Alzheimer’s, cancer and multiple sclerosis.
requires that astronauts get 8½ hours of sleep per night on missions to avoid long-term sleep loss, fatigue-induced errors and health complications. Proper shut-eye in zero gravity can be challenging, and astronauts on board the International Space Station struggle with sleep issues just like people on Earth. Fortunately, the Fatigue Countermeasures Laboratory at
’s Ames Research Center in Mountain View, California, is developing tools to help astronauts overcome sleep challenges. Led by Dr. Erin Flynn-Evans, the lab also conducts simulated space missions to understand how crew members might perform when sleep is restricted while living on Mars or the moon. Across the universe The Voyager space probes took off in 1977.
’s Jet Propulsion Laboratory in Pasadena, California, calls them her “senior citizens.” “I kind of describe them as twin sisters,” Dodd said. “One has lost its hearing, and it needs some hearing aids, and another one has lost some sense of touch. So, they’ve failed differently over time. But in a general sense, they’re very healthy for how old they are.” With care and monitoring, Dodd hopes to keep these trailblazing missions operating for years to come.
