"The Scully Effect" is the idea that Dr. Dana Scully (heroine of the "X-Files," scientist, and FBI agent) inspired a huge increase in women joining STEM fields, but what if there's more to the story? Host Trace Dominquez looks into the study behind "The Scully Effect" and explores if there are other factors that affected how people viewed STEM in the 1990s. Part of the "Uno Dos of Trace" series.

Today, people send emails, text messages, and status updates instantaneously. But not so long ago, messages were handwritten and travelled no faster than people could carry them. With the invention of the telegraph and then the telephone, instant communication was born. Radio and television created an industry for mass entertainment that continues to grow, and the computer age changed how data is crunched. With the invention of the internet in the 1980s, the world of communication has truly shrunk.
In this episode, host Dianna Cowern explores one of the most mysterious discoveries in physics from the 1960's: a constant microwave signal that seemed to be coming from everywhere in the universe. It turned out to be light from an unusual process 13.8 billion years ago and originated from the beginning of the universe. Part of the "Physics Girl" series.
Explores the strange and relatively unknown world of sleep-a world in which we spend approximately one-third of our lives. Shows how the discovery of REM (Rapid Eye Movement) during our dream period in the early 1950s by Dr. Nathaniel Kleitman at the University of Chicago brought about an understanding of the mechanism of sleep. Before his discovery, it was believed that during sleep the brain was in a state of rest. Also, overviews the nature and frequency of dreams and nightmares, and sleep disorders such as insomnia, apnea, and narcolepsy that affect millions of Americans.
The evolution of the uses of corn coincides with some significant historical events. Throughout history, it has been a staple in the human diet, but in the 1950’s, it became the main ingredient in the meat industry. Farmers used corn to shrink the growth periods of cattle to meet the demand of the consumer. Corn syrup was born from the Cuban Embargo. Today, genetically engineered corn is seen in nonfood products.
In contrast to the peaceful wildlands featured in the prior segments, the urban campus of the University of California-San Diego (UCSD) seems like an unlikely place to find field biologists studying juncos. But in the early 1980s, some juncos decided to make this atypical urban and coastal habitat their year-round home. Since then, scientists have documented a remarkable array of changes in the physical traits, behaviors, and physiology of the colonist population of juncos at UCSD when compared to juncos from the nearby native range. Part of Ordinary Extraordinary Junco (Chapter 6).
In some parts of the world, there is an intimate connection between the infectious parasitic disease "malaria" and the genetic disease "sickle-cell anemia." A keenly observant young man named Tony Allison, working in East Africa in the 1950s, first noticed the connection and assembled the pieces of the puzzle. His story stands as the first and one of the best understood examples of natural selection, where the selective agent, adaptive mutation, and molecule involved are known-and this is in humans to boot. The protection against malaria by the sickle-cell mutation shows how evolution does not necessarily result in the best solution imaginable but proceeds by whatever means are available.
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.

The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Ms. Frizzle's class takes a field trip inside a 1950s sci-fi film. The movie's main character, the power-mad General Araneus is determined to destroy the mantis, but Phoebe wants to trap it and save it. Shrinking to the size of real spiders, the kids discover how spiders construct a variety of silky snares, making them world-champion trappers. Can the kids save the mantis — and stop Araneus before it's too late?
The 1960s world population has nearly doubled and now tops 7 billion. Population growth, though little discussed, is putting an unprecedented burden on the planet's life systems. Brings to light the connection between overpopulation and our most pressing environmental and humanitarian problems, as well as the solutions. Also, follows Beth, an American mother and child rights advocate, who grew up in a large family of 12 as she travels to Africa to witness first-hand the impact of population growth in the developing world and its role in exacerbating poverty. While there, she meets a young Ethiopian woman, Zinet, who comes from a poor family of 12, but has found the courage to break free from long-held cultural barriers holding back women. Features a broader discussion of the solutions to overpopulation in both the developed and developing world.
Welcome to the North Carolina State University (NCSU) Phytotron, a singular facility for growing plants under various combinations of strictly controlled environmental conditions. Scientists are able to conduct all types of plant research here, from studies of disease-resistant crops to drought-proof grasses to new biofuels. The NCSU Phytotron was built in the 1960s with support from the National Science Foundation (NSF), and was used a decade later to help prevent a collapse in the U.S. corn crop from fungal disease. Now, after more than a generation of such research breakthroughs, the Phytotron has received additional support from NSF for a 21st century makeover. The renovations include a new Biosafety Level 3 (BSL-3) lab with a greenhouse that houses high security research, such as experiments with viral and bacterial pathogens. Part of the National Science Foundation Series “Science Nation.”
Proteins are the workhorses of cells. With support from the National Science Foundation, University of Arkansas biochemist James Hinton has been researching their structure and function for decades. Back in the 1990’s, he had a vision to study these huge protein structures in 3D and now, in cooperation with a company called Virtalis, his vision has become a reality. The new system allows researchers to enlarge the visual of a protein to room-size, so they can examine it from all angles, to better understand its structure and function. The new 3D visuals are also helping Hinton realize his other vision to better engage students in his discoveries and science in general.
