Can you x-ray a goldfish? A discussion with a veterinary radiologist.
Before x-rays were used for medical purposes, they were used for entertainment. X-rays are part of the electromagnetic spectrum and are utilized in a variety of radiography procedures that are currently taught to aspiring veterinary students. Liane Shaw, Diagnostic Imaging Senior Instructional Veterinary Nurse at the Purdue University College of Veterinary Medicine, describes the use of x-rays within these procedures and gives us a crash course in the history and properties of x-ray waves.
Where are the ingredients in your medicine coming from?
We all take medicine at some time or another, but what do we know about how these medicines are made? We asked Joe Topczewski, a chemist who has been part of both academia and industry, about pharmaceuticals: how they are made, how they become available, and how they are regulated. We learned that there is a lot of freely available information on federal government pages regarding most pharmaceuticals that are accessible to the general public.
Getting the Green Light: How a research program is chosen for NASA funding
How is a research program chosen for funding by NASA? As various scientific field campaigns are implemented, some of the campaigns reach the scientific research community and program scientists like Ken Jucks, Program Scientist at NASA Headquarters in Washington, D.C. Programs selected through peer-review for funding by NASA focus on answering science questions that are important to society, and that include the development of a solid, scientific approach toward answering these questions. The role of a NASA Program Scientist is to discover appropriate field campaigns from the research community that are happening during a time when NASA can organize funding to support the campaigns.
NASA is divided into a number of different Mission Directorates. The DCOTSS Campaign was funded as part of the Science Directorate (earth science division) to provide an opportunity that might enhance the capability of scientists to better understand the current state of the Earth system and to enable continual improvement in the prediction of future changes.
Heliophysics and Solar Eclipses with NASA HEAT
The Sun is both a natural laboratory for plasma physics and the focus of the field of study known as Heliophysics. Heliophysics involves the physics of how the Sun actually works. Dr. Michael Kirk, P.I. of the NASA Heliophysics Education Activation Team, defines the state of matter known as plasma, and explains how studying the Sun helps us better understand satellites, radio signals, GPS signals, and many other technologies that affect our life every day. Solar eclipses, including the upcoming annular solar eclipse (October 2023) and total solar eclipse (April 2024), are also discussed.

World Water and Wetlands: Looking at the Present and Considering the Future
There are many variables that play a role in understanding the impacts of water as it relates to the development of different environments. Kayla Cotterman is an Environmental Scientist with the Lochmueller Group who studies the impact to wetlands for groups wanting to develop. Cotterman discusses variables such as water usage, storm water, runoff, and historic rain events. Factors such as these are taken into consideration when advising engineering firms about the construction of buildings, so that they will be able to withstand the environment in which they are being built.
What a Chemist has to do with an OLED TV
When you look at a leaf, what color do you see? While a leaf may appear green, it is not necessarily producing green light. The leaf absorbs wavelengths of red light, and reflects the green light that we see. Professor Alexander Wei’s research group synthesizes molecules and nanomaterials, and studies how these materials interact with light. Wei discusses luminescence, fluorescence, phosphorescence, and where we can observe these light-related properties in our everyday life. Wei’s group is currently focused on designing and developing new materials that produce blue light. There is a current need for blue-light producing materials that can be used with an exciting new technology related to the next generation of flat panel television displays: Organic Light-Emitting Diodes (OLEDs).

Good for learning new science
I enjoy listening to these. They have a lot of variety in science. It's nice to learn from actual scientists and hear about new research.
I really enjoy listening to this podcast! So much fun and very informational! Love learning about all of these different topics! My favorite episode was about the zombie cicadas! Definitely recommend!
Always a great way to learn from experts
I always learn something new from the Superheroes of Science podcast. These are experts in their fields and they don’t skim over topics. They drill down into the subject. My favorite so far has to be the fireworks podcast. Well done!
