Online language exchange community Science writing award winner makes statistical sense of an imperfect world Hi there – I'm your friendly neighbourhood statistician, and I've got a few questions if that's all right. First up, how old are you? OK, and how much do you weigh? Good, good, now how many calories do you eat on an average day? If you're anything like me you'll have had a mixed response to that lot. Welcome to the world of measurement error, a place I have lived for the last three years of my life while working towards a PhD in statistics. So what can we do? Despite being a relatively new area, there's already a mind-bogglingly large range of different models and methods for dealing with measurement error. By this point you might be wondering exactly what it is I do all day, and I'm the first to admit that a statistician's life is as glamorous as, well, as glamorous as you'd expect. So next time you see a headline about a groundbreaking medical discovery, spare a thought for the statisticians working behind the scenes.

Welcome to | From Skydiving to Biometrics: One Entrepreneurs' Story | ScienceLives | ACTiVATE Series This ScienceLives article was provided to LiveScience in partnership with the National Science Foundation. After Mary Haskett earned her degree in applied mathematics, she took an unusual career path and became a skydiving instructor. Little did she realize that her choices would lead her to work on biometric projects in a war zone and ultimately become a serial entrepreneur. That early experience running a small skydiving business led her to the NSF-funded ACTiVATE® program, an entrepreneurship training program that teaches technical and business skills to help women create their own companies. After her second company was acquired by a defense contractor, Haskett decided to launch her third company along with co-founder Alex Kilpatrick: Tactical Information Systems, a company focused on using biometric technology as a low-cost, easy-to-use identification service. Name: Mary Haskett Age: 45 Institution: Tactical Information Systems Field of Study: Biometrics and Entrepreneurship

Tests Under way on the Sunshield for NASA's Webb Telescope Tests Under way on the Sunshield for NASA's Webb Telescope NASA is testing an element of the sunshield that will protect the James Webb Space Telescope's mirrors and instruments during its mission to observe the most distant objects in the universe. The sunshield will consist of five tennis court-sized layers to allow the Webb telescope to cool to its cryogenic operating temperature of minus 387.7 degrees Fahrenheit (40 Kelvin). Testing began early this month at ManTech International Corp.'s Nexolve facility in Huntsville, Ala., using flight-like material for the sunshield, a full-scale test frame and hardware attachments. The test sunshield layer is made of Kapton, a very thin, high-performance plastic with a reflective metallic coating, similar to a Mylar balloon. The tests are expected to be completed in two weeks. The test will be done on all five layers to give engineers a precise idea of how the entire sunshield will behave once in orbit. Related Links:
