Gut Microbes and Autoimmune Disease // What’s in YOUR Gut? The American Gut Project

 

Headlines:

  1. New CU Studies on GroundLevel Ozone, with NOAA’s Sam Oltmans, CU researcher Daven Henze and NASA’s Kevin Bowman
  2. Good Cholesterol, Bad Cholesterol and “Ugly” Cholesterol
  3. Tonight’s Denver Cafe Sci features Tad Pfeffer:  Getting sea level predictions right

Features:

We look at a new study where researchers, led by Jayne Danska transferred gut microbes from male mice to young female mouse pups, and in the process, raised the testosterone level in the female mice and protected them from getting Type 1 Diabetes.  Danska’s research team includes Daniel Frank   at University of Colorado School of Medicine in Aurora, and Chuck Robertson at CU Boulder.

And we look at a new kind of science, offered in The American Gut project, featuring CU scientist Rob Knight.

Medical Marijuana and Traffic Accidents//Ron Rosedale Critiques Body Mass Index Study

Apple Versus Pear Shape

HEADLINES:

  1. Diabetes Drug Metformin – University of Pennsylvania Researcher Morris Birnbaum reports in Nature that Metformin blocks a hormone that tells the liver to melt muscle to make more blood sugar. (Go here for an extended interview with Morris Birnbaum)
  2. Climate Change – Research shows that timely political action has a bigger impact than waiting.
  3. Boulder Cafe Scientifique – Tonight’s Cafe Sci features CU Boulder researcher Monique LeBourgeois (who we interviewed in detail in previous broadcast) on the topic of kids and sleep.

Medical Marijuana States

MAIN FEATURES:

We talk with scientists who are part of two new University of Colorado – Denver studies about alcohol and marijuana – 1) Ben Crost presents a study of marijuana use versus alcohol use which concludes that the minimum drinking age of 21 increases marijuana use among teens (until age 21, alcohol use is lower and marijuana use is higher.  After age 21, alcohol use goes up and marijuana use goes down).  Daniel Rees and Mark Anderson are among the authors on a study of Medical Marijuana and Traffic Fatalities that view the question of who uses what from the other side.  Their study looks at an exception to the rule – the 16 states and District of Columbia with some years now, have had medical marijuana laws.  In these Medical Marijuana states, teen use of marijuana appears to rise at age 18 (that’s the age at which teens no longer need to have their parent’s permission to get a Medical Marijuana card. )  But even more interestingly, in these Medical Marijuana states, traffic fatalities go down.  These authors look at why. (Go here for extended interviews with Crost and Anderson)

We also discuss the new study from the Centers for Disease Control and Prevention that analyzed the link between Body Mass Index (BMI) and death.  BMI is calculated as weight in kilograms divided by height in meters squared study.  The study concluded that while very obese people were likely to die sooner than others, people who were moderately overweight, or even slightly obese, were less likely to die than were people of normal weight, or people who are thin.  Medical doctor and researcher on aging, Ron Rosedale, puts this study in historical perspective, pointing out that the British Medical Journal the Lancet published a similar study in 2006 that concluded that BMI is not a very useful measure of health, and other measures, such as waist to hip ratio and certain hormone levels, might be better at predicting health and longevity.

The Fat Switch – Richard Johnson MD

Headlines:  

  1. Chemicals that make drinking water cleaner, might increase allergies to food
  2. Rumors run amok about “historic” Mars Mission press conference
  3. West Nile Virus, Lyme’s disease, and Dengue fever on the rise

Main feature (6 minutes in):  We’re in that time of year when animals hibernate.  Before they started their long winter’s nap, they fattened up, so they can make it through the winter.  According to CU Health Sciences researcher, Richard Johnson, we humans also evolved to put on weight to make it through leaner times.  But for us, it’s not a change of seasons that gets the weight gain started.  It’s a specific trigger, called, “Sugar.”  Specifically a kind of sugar called fructose, found in honey, fruit juice, corn syrup, and even regular table sugar.  In his new book, The Fat Switch, Johnson traces the increasing availability of this fructose sugar among humans and how it has now made people fat, and sick for thousands of years.  For instance, you think the pharoahs were all buff, and skinny?  Many mummies have lots of skin folds, which means that, as living humans, many were fat.  Johnson also talks about kings who loved sugar so much, sometimes they made sugar statues . . . and ate them . . . leading many to be very fat and prone to modern diseases such as diabetes and heart attack and stroke. Now let’s listen in, as How on Earth’s Shelley Schlender talks with Dr. Richard Johnson, about how sugar affects children.  They begin with how too much sugar can make a person’s body get stuck, storing the sugar as fat.

The American Gut – What’s in YOUR Gut?

humanfoodproject.com/american-gut/

from humanfoodproject.com/american-gut/

We share three new findings that include contributions from Colorado scientists:  1.  Diane McKnight coauthors study about Bacteria that thrive in a frigid hell-hole – the pitch-dark, super-salty, poisonous Lake Vida in Antarctica, 2.  William Colgan offers new ways to calculate a glacier’s melting rates, 3.  Alicia Karspeck offers a new weather forecast – Cloudy with a Chance of Flu?

(6:00) Then we talk with Jeff Leach, founder of the Human Food Project, which has teamed up with CU researchers who include Rob Knight to create a crowd-sourced, crowd-funded way to learn more about the microbes that live in us and on us.  The new project is called The American Gut.  The deadline to sign up is January 7th.

Stopping Cancer in its Tracks – Telomerase Receptor Inhibition

Last month, CU Nobel Prize Winner Tom Cech (Check) and colleagues announced a breakthrough in their quest to stop cancer.  It involves an enzyme known as telomerase (tell-AH-mer-aze), which helps cells divide almost endlessly – helpful when a child is growing.  In adults, most cells stop responding to telomerase.  Instead they save up a limited number of cell divisions timed to last through old age.  Cancer cells are different.  They are great gobblers of telomerase.  That’s where CU discovery comes in.  It’s a way to possibly prevent cancer cells from tanking up on telomerase.  Cech says that while human trials are years off, the discovery looks promising.  For more, here’s How on Earth’s Shelley Schlender, talking with CU Nobel Prize winner, Tom Cech, in an extended version of this interview on cancer:
