• N.M. Electric Car Challenge encourages students’ interests in STEM

    Aspiring automotive engineers from twenty-seven middle schools across New Mexico competed in the New Mexico Electric Car Challenge on 22 November at the Highland High School gymnasium in Albuquerque. The goals of the challenge are to present science and math concepts to students in a fun and exciting way, encourage team building, stimulate creative thinking, and develop students’ writing and presentation skills. The New Mexico Electric Car Challenge is a result of the collaboration and commitment of several partners to advance science, technology, engineering, and math (STEM) programs and opportunities for schoolchildren.

  • China’s second “great wall” is not so great

    China’s coastal regions are only 13 percent of the country’s land area, but contribute 60 percent of its gross domestic product. With that come layers of incentives to turn lush wetlands into engines of development and industry. A new study finds that China’s second great wall, a vast seawall covering more than half of the country’s mainland coastline, is a foundation for financial gain - and also a dyke holding a swelling rush of ecological woes.

  • New, updated resource on STEM education, workforce

    It just became a lot easier for educators, students, parents, policymakers and business leaders to learn more about national trends in education and jobs in science, technology, engineering, and mathematics (STEM). The National Science Board (NSB) last month released an interactive, online resource featuring new and updated data and graphics about STEM education and workforce in the United States and providing facts on topics such as student proficiency, college degrees in STEM fields, and jobs in science-related occupations.

  • Floating cities increasingly attractive prospect in the face of sea level rise, floods

    More and more urban planners and disaster managers are asking the question: “Has the time come for floating cities?” Experts say thatin the face of climate change-driven sea level rise and shifting weather patterns poised seriously to impact many cities over the course of the next decades, the option of having cities that can accommodate shifting tides is making more and more sense.

  • “Active Physics” incorporates active-learning techniques while still being taught to large classes

    Large lecture courses notoriously discourage students from going into the sciences, but an innovative physics course helps to prevent this first-year slide. “Active Physics” incorporates active-learning techniques, but still is taught to large classes. Active Physics consistently outperformed traditional lecture courses in conceptual learning and in attitudes toward learning and problem solving.

  • Cold-formed steel construction withstands seismic challenges better than expected

    Engineering researchers have provided the building blocks necessary for enabling performance-based design for cold-formed steel buildings, structures that have shown in shake-test experiments at the State University of New York at Buffalo to withstand seismic loading much better than previously expected. Light, strong, and easy to construct cold-formed steel (CFS) buildings are repetitively framed with light steel members and conform to well-defined seismic design codes. Until this latest research, however, engineers and builders significantly underestimated the seismic strength of cold-formed steel structures.

  • Creating sustainable university and college STEM programs

    A new study has identified two factors that characterize sustainable university and college programs designed to increase the production of highly qualified physics teachers. Specifically, one or more faculty members who choose to champion physics teacher education in combination with institutional motivation and commitment can ensure that such initiatives remain viable. Science, Technology, Engineering and Math (STEM) teacher shortages are especially acute in physics, and the study points the way for institutions seeking to increase the number of STEM graduates prepared to teach.

  • Socioeconomic status may influence understanding of science

    When it comes to science, socioeconomic status may widen confidence gaps among the least and most educated groups in society, according to a new study. The findings show that similar levels of attention to science in newspapers and on blogs can lead to vastly different levels of factual and perceived knowledge between the two groups. Notably, frequent science blog readership among low socioeconomic-status groups actually lowered their scores on factual tests of scientific knowledge while high levels of attention to science in newspapers caused them to feel they were less knowledgeable compared to those who read less or those from higher socioeconomic backgrounds.

  • Earthquake researchers get online primer for simulation method

    Researchers now have access to expert instruction for an emerging simulation method to study seismic effects on structures and to design buildings that better withstand strong earthquakes. The National Science Foundation’s (NSF) George E. Brown Jr. Network for Earthquake Engineering Simulation (NEES) is providing a primer on its NEEShub. he primer explains how to use hybrid simulations, methods that are helping researchers study the effects of earthquakes on buildings and other structures.

  • Correcting pipeline problems to aid STEM diversity

    Educators and policymakers have spent decades trying to recruit and retain more underrepresented minority students into the science, technology, engineering, and math (STEM) pipeline, to no avail: Traditionally underrepresented groups remain underrepresented. A new analysis of disappointing results in the pipeline’s output leads two Brown University biologists to suggest measures to help the flow overcome an apparent gravity.

  • L.A. to catalog buildings at risk of collapse during a major earthquake

    After years of efforts to get officials to catalog buildings at risk of collapse during a major earthquake, Los Angeles City Council late last month instructed building officials to establish a database of such buildings. About 29,226 buildings built before 1978 are subject to survey, but city officials would use mapping programs to narrow down which structures need further field inspection. The city estimates roughly 5,800 buildings are at risk, and an additional 11,690 buildings will need inspection on site to determine whether they are soft-story buildings or not. Los Angeles has yet to decide what to do once it compiles the list, and whether to require retrofitting of vulnerable buildings, but seismic experts and policymakers insist that finding out which buildings are vulnerable is a necessary first step.

  • Urban man-made drainage may increase risk of flooding

    Installing drainage systems in developing towns and cities can cause water to reach rivers more quickly, potentially raising the risk of flooding, say scientists. They suggest that, in some cases, storm drains may do more to increase the risk of flooding than changes in the land surface.

  • New, more effective teaching approach for engineering education

    Purdue University researchers who developed a new approach more effectively to teach large numbers of engineering students are recommending that the approach be considered for adoption by universities globally. The system, called the Purdue Mechanics Freeform Classroom, allows students to interact with each other and faculty online while accessing hundreds of instructional videos and animations. The approach also might be used for any large STEM-related courses.

  • Better building design, maintenance would cut building sector’s emissions by around 80%

    The construction industry, which uses half of the 1.5 billion tons of steel produced each year, could slash its carbon emissions by as much as 50 percent by optimizing the design of new buildings, which currently use double the amount of steel and concrete required by safety codes. If buildings are also maintained for their full design life and not replaced early, the sector’s emissions could in total be cut by around 80 percent.

  • Foreign graduate enrollment in science and engineering continues to rise

    The number of citizens and permanent residents enrolled in science and engineering (S&E) graduate programs in the United States declined in 2012, while the number of foreign students studying on temporary visas increased, according to new data from the National Science Foundation (NSF).
