Battling Obesity: It’s Time to Fight Fat with Fat Episode 44 by Lisa Willemse (Click here to directly access the MP3) (Access the full text transcript) Brown fat may become the newest weapon in the war against obesity. Unlike white fat, which stores excess energy, brown fat is highly metabolic, meaning it burns energy and therefore helps to regulate weight. New research has found that the same stem cells that produce muscle also produce brown fat and that a particular switch (namely a gene regulator known as microRNA-133) is responsible for telling the stem cells which type of cell to become.  Listen to the podcast to learn what happened when the researchers flipped the switch to produce more brown fat and what that might mean for human health.

Medical Isotopes Without the Nuclear Reactor Episode 43 by Mark A. Ferguson (Click here to directly access the MP3) (Access the full text transcript) Traditionally, nuclear reactors - and the one at Chalk River Nuclear Laboratories in particular - have been used to create medical isotopes. But when the National Reseearch Universal Reactor nuclear reactor at in Chalk River was closed in 2007, it caused a worldwide shortage in these important compounds used in the diagnostic imaging of nearly 6000 patients a day around the world. Creating a new source of isotopes required a new way of doing things - and that’s where synchrotrons and particle accelerators came to the rescue. Listen to learn more…   Mark A.

Get Your Light Right: Set Your Internal Clock to Avoid Health Hazards Episode 37 by Niki Wilson (Click here to directly access the MP3) (Access the full text transcript) For most of our evolution as a species, humans wandered the earth in sync with the light/dark cycles created by the sun and the moon. This relationship has shaped the formation of our body chemistry and physical make up. Our bodies adjust to daily and seasonal changes in light through physiological adaptations. Awareness of light (and dark) and the time of day when we are exposed to light (and specific wavelengths of light) can have a dramatic effect on our well being and directly impact our internal clock.
