For as long as parents and babies have been smiling, laughing, and cooing at each other, scientists still have a lot of questions about just how these interactions help infants develop. With support from the National Science Foundation, University of Miami psychology professor Daniel Messinger and his colleagues want to learn more about child development by studying how moms, dads, and babies respond to each other. Part of the National Science Foundation Series “Science Nation.”

In the early 1950s, American biologist James Watson and British physicist Francis Crick came up with their famous model of the DNA double helix. The structure of DNA, as represented in Watson and Crick's model, is a double-stranded helix. The sugar-phosphate backbones of the DNA strands make up the outside of the helix, while the nitrogenous bases are found on the inside and form hydrogen-bonded pairs that hold the DNA strands together. Other topics covered include DNA replication, RNA transcription, and RNA translation. Part of the "Biology" series.
Mary Elizabeth Wusk started her work at NASA as a summer intern. She began working in aircraft instrumentation and continued developing her career by conducting research on aircraft. With her background in physics and electrical engineering, she has supported and led teams that delivered ground and flight hardware systems. Mary Beth now uses her technology development background in NASA’s Game Changing Development Program Office. Part of the "Women@NASA" series.
Live-action, colorful footage illustrates the exciting, natural highlights of summer. Activities of plants and animals during the summer season are explored. Additional concepts and terminology include: growth, development, seeds, food storage, recreation, and solstice.
The rapid population growth in large urban centers of the world has made it necessary to look for alternatives to development in order to make cities suitable for living. PROSPECTA, an international event, aims to promote ideas of change by thinking about society's future, starting with proper planning and development.
Jennifer Keyes began her NASA career as an intern and then a co-operative education student in 1999. In these programs, she worked on projects in atmospheric science, subsonic aerodynamics, and space exploration. Currently she is an aerospace engineer working as a systems analyst for the Office of Strategic Analysis, Communication, and Business Development at NASA Langley Research Center. In this role, Jennifer supports the senior leadership team as the lead for strategic governance and business development. Part of the "Women@NASA" series.
Energy has been essential for the development of human activities from the Industrial Revolution to present day. Over the course of history, human consumption of energy has increased significantly. Currently, society depends largely on nonrenewable energies that come from fossil fuels. However, the increase in greenhouse gas emissions has highlighted the need to change from fossil fuels to renewable energy sources that reduce environmental contamination. Many industries are committing to the development of alternative energy sources that don’t contribute to global warming. Chapter 9 of Air: Climate Change Series.
Part of the "Green Careers" series. Details the entire range of jobs needed to make solar power a reality from research and development, design and marketing, and financial analysis to construction and project management. Engineers, analysts, and managers share how they work in this emerging green industry and how they found the opportunity to be part of the clean energy solution. Jobs profiled include the following: research and development engineer, design engineer, marketing manager, financial analyst, construction manager, and project manager.
El Niño and La Niña are periodic weather patterns resulting from interactions between the ocean and the atmosphere in the Pacific Ocean. Ocean temperatures indicate the presence of El Niño and La Niña, which sometimes lead to extreme weather in many parts of the United States. NOAA climatologists closely track the development of these oscillating systems, which typically last between one to two years. With so much at stake, it’s critical to be able to monitor and forecast when El Niño or La Niña is developing so governments, businesses, and private citizens can prepare.
Anna has built a successful business from the ground up, and upon retirement, she leaves the company to her employees, not to her son. What does that decision tell us about Anna's psychology and about the development of the human brain over a lifetime? Explores the emotional and neurological elements of learning, explaining how the brain processes and stores experiences and prepares for future decision-making. Employing real-to-life dramatizations, Anna's journey from innocent teenager to philosophical retiree--and the changes that take place in her cortex, hippocampus, and neural synapses as she faces and overcomes challenges--are all depicted. In addition, several influential brain experiments from the past decade are described.
Investigates plant reproduction: concepts, terminology, types of reproduction, pollination, and seed development and germination. Includes questions, review, and a quiz.
Students explore the life cycle of plants. This video discusses the process of plant development from a small seed to a mature plant.
USGS (US Geological Survey) technologist Rick LaHusen describes how the development and deployment of instruments plays a crucial role in mitigating volcanic hazards.
Explains the development of the water snail from egg to adult, hard-shelled mollusk. One of nine segments in a series, with all nine available on a DVD.
Millions of years ago, a group of bacteria, the cyanobacteria, developed a new way to harness energy from the sun. This new development had important consequences for the evolution of both the atmosphere and the diversity of life on Earth.
Technological development and advances in mobile devices, including the growth of Apps, have generated a technological revolution. Some experts label this as the greatest revolution sin the Industrial Revolution. In this episode, Nerdo Cavernas demonstrates the top 3 applications of each operating system for the most popular smartphones and tablets.
Under Prospecta Colombia 2012, an event organized by the Universidad Nacional Abierta y a Distancia, issues were raised and discussed related to the growth and development of cities. Nerdo Cavernas talks with the most prominent speakers present at this important event.
In an effort to improve the quality of educational content in Colombian University Television, The History Channel Experience was held. This workshop was designed to motivate producers and Colombian University filmmakers to use international production systems in their presentations and in the development of audiovisual projects.
The project is called VORTEX2. For five weeks in the spring of 2009, and again in spring 2010, 100 researchers and scientists from 16 universities deployed about 40 vehicles armed with high tech equipment to measure and probe tornadoes and tornado development.
Physical activity and quality sleep are both vital for healthy bodies, as well as healthy brains. Viewers learn the relationship between activity, boredom, and sleep and how each plays a role in healthy development of children. Part of "The Brain" series.
