Long before scientists and engineers could send astronauts into space, they had to convince the public—and the officials who would fund these first forays—that such a wild undertaking was possible. “You couldn’t just say, ‘We’re going to build rockets,’ and ask people to believe it—you really had to show them how,” says Piers Bizony, a British journalist and author of the lavishly illustrated book , out this month. It reveals how the agency and its contractors sold many of their otherworldly ideas to a sometimes skeptical nation.Culled from a carefully chosen reserve of approximately 3,000...…Long before scientists and engineers could send astronauts into space, they had to convince the public—and the officials who would fund these first forays—that such a wild undertaking was possible. “You couldn’t just say, ‘We’re going to build rockets,’ and ask people to believe it—you really had to show them how,” says Piers Bizony, a British journalist and author of the lavishly illustrated book , out this month.

Moonwalkers take heart—China’s Chang’e 4 lander has made the first detailed measurements of the intense radiation that blasts the lunar surface and found that it’s safe for human exploration. The results give researchers a better idea of how much protective shielding future crews will need.Astronauts on the Apollo missions of the 1960s and ’70s carried dosimeters to measure their radiation exposure, but the devices captured total exposure from their entire journey—not merely their time on the Moon’s surface. Ever since, scientists have had to estimate the radiation doses of crews bounding...…Moonwalkers take heart—China’s Chang’e 4 lander has made the first detailed measurements of the intense radiation that blasts the lunar surface and found that it’s safe for human exploration.

The frequency of combined droughts and heatwaves - which are more devastating when they occur in unison - has substantially increased across the western U.S. and in parts of the Northeast and Southeast over the past 50 years, according to a new study. The findings also suggest areas that experience compound dry-hot extremes are growing less scattered and more connected, resulting in larger impacted regions that place enormous strain on regional and national relief efforts.

Humans are unusual among animals for continuing to provision and care for their offspring until adulthood. This “prolonged dependency” is considered key for the evolution of other notable human traits, such as large brains, complex societies, and extended postreproductive lifespans. Prolonged dependency must therefore have evolved under conditions in which reproductive success is gained with parental investment and diminished with early parental loss. We tested this idea using data from wild chimpanzees, which have similarly extended immature years as humans and prolonged mother-offspring...…Humans are unusual among animals for continuing to provision and care for their offspring until adulthood.
