Science and math educators are keeping classes knowledgeable and interesting, but they are not promoting science, technology, engineering, and math (STEM) careers, according to most students surveyed by Harris Interactive for the American Society for Quality (ASQ). High school student respondents also say they do not think STEM knowledge is crucial to acquiring a good job. “We believe that as students get older and begin to diversify their studies and become more aware of the wide range of available career opportunities, they start to think that math and science aren’t necessarily critical to their job hunt,” says ASQ’s Maurice Ghysels. He says that teachers often leave out discussions of career options because of time and budget constraints. One of the challenges is that teachers themselves may have little knowledge of the wide variety of available STEM career options. Despite these drawbacks, there are ways to kindle interest in STEM careers among students, one of them being to offer hands-on lab activities and real-world examples of STEM applications at an earlier educational level such as elementary school.

The Blue Ribbon Task Force on Sustainable Digital Preservation and Access recently released a report addressing the problem of ensuring that digital information will be accessible in the future. The report provides principles and actions to facilitate long-term economic sustainability and context-specific recommendations geared toward four specific scenarios–scholarly discourse, research data, commercially-owned cultural content (such as digital media), and collectively produced Web content such as personal Websites and blogs. “Valuable digital information spans the spectrum from official e-documents to some YouTube videos,” says Task Force co-chair Fran Berman. The report also cites four distinct prioritized courses of action–organizational action, technical action, public policy action, and education and public outreach action. The report concludes that preservation strategies need to develop at their own pace. “A key element of a robust sustainability strategy is to anticipate the effect of these changes and take steps to minimize the risk that long-term preservation goals will be impacted by short-term disruptions,” says Task Force co-chair Brian Lavoie.

The European Union 3Plast research consortium plans to develop sensors that can be printed onto plastic film and attached to everyday objects. The sensors are being designed to respond to changes in temperature and pressure, which would enable them to detect the movement of a finger. “The sensor is combined with an organic transistor, which strengthens the sensor signal,” says project leader Gerhard Domann. Researchers have already printed sensors onto film, and are now optimizing transistors that can amplify changes in temperature and pressure. “By providing everyday objects with information about their environment–for example, whether a person is approaching–by means of pressure and temperature sensors, we can create and market new devices that can be controlled just by pointing a finger,” Domann says. It will likely take several years to print sensors on large surfaces, he says.
