Sexual reproduction is likely to be impossible in space due to cosmic radiation bombarding the human body.
Researchers at the agency’s Ames Research Centre in California found that without effective shielding on spacecraft, powerful proton particles would probably sterilize any female embryo conceived in deep space.
Women with high levels of the sex hormone oestrogen have prettier faces, research suggests. The findings make evolutionary sense – men are attracted to the most fertile women, the University of St Andrews team told a Royal Society journal. (pics)

A study has investigated how the differing fertility rates between religious and secular individuals might affect the genetic evolution of society overall.
In the past 20 years, the Amish population in the US has doubled, increasing from 123,000 in 1991 to 249,000 in 2010. The huge growth stems almost entirely from the religious culture’s high fertility rate, which is about 6 children per woman, on average. At this rate, the Amish population will reach 7 million by 2100 and 44 million by 2150. On the other hand, the growth may not continue if future generations of Amish choose to defect from the religion and if secular influences reduce the birth rate. In a new study, Robert Rowthorn, emeritus professor of economics at Cambridge University, has looked at the broader picture underlying this particular example: how will the high fertility rates of religious people throughout the world affect the future of human genetic evolution, and therefore the biological makeup of society?
