Science Friday: DNA Testing

We’re very excited to bring you this weekly feature – Science Friday, a science talk show produced by NPR. Each week, a new video takes on a different on science topic, in an effort to bring an educated, balanced discussion to bear on the scientific issues at hand.

You may remember that we started this feature more than a year ago – but technical difficulties kept us from making it a regular appearance. Thanks to the fine folks at SciFri, however- I think we’ve got it figured out. Hopefully, we’ll be bringing you the science-y goodness every Friday from now on.

This week we follow two high school students from New York as they perform a DNA test on foods to see just what ingredients are in our everyday meals. They review if goat milk really comes from goats, the origin of caviar, and what exactly goes into New York City hot dogs.

Live from the Field: Until Next Time…

 That’s all folks: digging’s done for this year.

For the past week and a half, the HMNS paleontology team – led by Dr. Robert Bakker – has been back in Seymour, TX, digging for Dimetrodon at a site they’ve now been working for several years. (You can read more of what’s been found already in our daily blog from the field in 2007). Today, they said goodbye to the site for several months, after leaving it covered and safe for the coming winter weather, and pulling out a ton (possibly literally) of new material to study and prepare until then.

David Temple – our associate curator of paleontology and a one of our BEYONDbones bloggers- provides this series’ farewell podcast with a wrapup of their discoveries – and a review of the local cuisine.


Never fear! If you miss the daily update, stop by the museum – members of the team and Museum volunteers often work to preserve these fossils in public areas, like the Paleontology Hall or the Dinosaur Mummy CSI exhibition. You can also check out earlier updates from this dig trip:

Live from the Field: Two for One!

A Dimetrodon vertebra,
found at the team’s dig site.

Our paleontology team – led by Dr. Robert Bakker – is back in Seymour, TX, digging for Dimetrodon at a site they’ve now been working for several years. (You can read more of what’s been found already in our daily blog from the field in 2007). Today, they’re wrapping things up to come back to Houston – and they’ve sent us two updates.

In the first, David Temple – our associate curator of paleontology and a one of our BEYONDbones bloggers, talks about the darker side of Texas paleontology - cactus spines – and how you protect a dig site for the winter weather.


In the second, we’re pleased to bring you an update from Tim Quarles. Tim was a member of the team that found and excavated Leonardo, the famous mummified dinosaur that is now on display here in Houston. He was also there for our recent trip to Malta, where Leonardo was found. So, the team was thrilled that he happened to be in Texas for a few days, and was able to stop by our dig site.  In his update, Tim gives us his impressions from digging in the Permian for the first time.

Live From the Field: Trench Warfare

Dr. Bakker leads a group of volunteers in carefully
excavating a plaster jacket filled with fossils and
matrix from the Seymour dig site the team has
been reporting from this week. They’re bringing
back several new jackets to work on over the
next few months.

Our paleontology team – led by Dr. Robert Bakker – is back in Seymour, TX this week, digging for Dimetrodon at a site they’ve now been working for several years. (You can read more of what’s been found already in our daily blog from the field in 2007).

Today’s update comes David Temple – our associate curator of paleontology and a one of our BEYONDbones bloggers. They’re wrapping up the dig, and he fills us in on the progress from yesterday, as well as what’s in store for the team today.

They’ll finish jacketing and removing as many fossils as they can from the site, and prepare what’s left to be sheltered until they return. They face two challenges: limited time and a paleontologist’s worst nightmare: rain.
