The biotech company AquaBounty Technologies of Waltham, Massachusetts, has developed a genetically modified Atlantic salmon that grows twice as fast as regular salmon. How has it done this?

Author Peggy Mason discusses empathy in non-primates, and the value rats place on freeing a companion--about equal to that of a stash of chocolate chips.
In Asia's Space Race: National Motivations, Regional Rivalries, and International Risks, Naval Postgraduate School professor James Clay Moltz discusses the potential militarization of fast-growing space programs in China, India, and Japan--and why US military officials are keeping watch.
