  • InfrastructureDamage-sensing, self-repairing concrete

    Skin is renewable and self-repairing — our first line of defense against the wear and tear of everyday life. If damaged, a myriad of repair processes spring into action to protect and heal the body. Clotting factors seal the break, a scab forms to protect the wound from infection, and healing agents begin to generate new tissue. Taking inspiration from this remarkable living healthcare package, researchers are asking whether damage sensing and repair can be engineered into a quite different material: concrete. Their aim is to produce a “material for life,” one with an in-built first-aid system that responds to all manner of physical and chemical damage by self-repairing, over and over again.

  • STEM educationU.S. engineering schools to educate 20,000 students to meet U.S. major engineering challenges

    In a letter of commitment presented to President Barack Obama at the White House Science Fair yesterday, 122 U.S. engineering schools announced plans to educate a new generation of engineers expressly equipped to tackle some of the most pressing issues facing society in the twenty-first century. Each of the 122 signing schools has pledged to graduate a minimum of twenty students per year who have been specially prepared to lead the way in solving such large-scale problems, with the goal of training more than 20,000 formally recognized “Grand Challenge Engineers” over the next decade.

  • STEM educationLockheed Martin recognized for supporting young girls’ STEM education

    Over the next eight years there will be more jobs available in Science, Technology, Engineering, and Mathematics (STEM) than any other occupation. The Society of Women Engineers (SWE) recently presented Lockheed Martin with its first “Invaluable” award for championing education programs that inspire the next generation of women engineers and technologists. Since 2010, Lockheed Martin has given more than $45 million to programs that promote STEM education.

  • STEM educationHigh school study in math declining among prospective teachers

    Math and science participation among New South Wales, Australia high school students has declined starkly over the past decade, which in turn is leading to fewer teachers with this crucial background for their work in schools, according to new research. “STEM is considered critical to all new economies. Yet, unlike many countries which show improving standards on international assessments of math and science, Australian 15 year olds’ scores have been declining since 2000,” said one of the researchers.

  • STEM educationImproving chemistry teaching throughout North America

    The Dow Chemical Company and the American Association of Chemistry Teachers (AACT) are partnering to invigorate chemistry education and support STEM (science, technology, engineering, and math) education in the nation’s schools. Dow and AACT will work together to convene a series of teacher summits and create more than 750 lesson plans, multimedia resources, demonstrations, and other high-quality chemistry teaching materials for use in K–12 classrooms. The work will be supported by a $1 million contribution from Dow to the AACT spread over a four year period.

  • STEM educationConsistency, collaboration needed for effective implementation of science teaching standards

    A new report just released today by the National Research Council offers guidance to district and school leaders and teachers on necessary steps for putting the Next Generation Science Standards (NGSS) into practice over the next decade and beyond. The report’s recommendations are informed by research findings that emphasize that science and engineering involve both knowing and doing; that developing rich, conceptual understanding is more productive for future learning than simply memorizing discrete facts; and learning experiences should be designed with coherent progressions over multiple years.

  • STEM educationColleges, labs develop STEM core curriculum

    The success of Lawrence Livermore National Laboratory’s Engineering Technology Program to educate veterans for technical careers has inspired a statewide push to create an educational core curriculum to prepare junior college students for technical jobs at California’s national labs. The core curriculum being designed by a consortium of community colleges, national labs, and nonprofit educational institutes emphasizes a heavy focus on science, technology, engineering, and math (STEM) courses to prepare women, minorities, veterans, and other underserved populations for high-paying jobs as technologists.

  • InfrastructureMicro-capsules and bacteria used in self-healing concrete

    Researchers are aiming to develop a novel self-healing concrete that uses an inbuilt immune system to close its own wounds and prevent deterioration. Self-healing concrete could vastly increase the life of concrete structures, and would remove the need for repairs, reducing the lifetime cost of a structure by up to 50 percent. Over seven per cent of the world’s CO2 emissions are caused by cement production, so reducing the amount required by extending the lifetime of structures and removing the need for repairs will have a significant environmental impact.

  • STEM educationN.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.

  • Coastal infrastructureChina’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.

  • STEM educationNew, 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.

  • Infrastructure protectionFloating 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.

  • STEM education“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.

  • Seismic protectionCold-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.

  • STEM educationCreating 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.
