Friday Quick Links

Researchers have proposed pulleys, sleds and wooden rollers as possible tools to move the huge slabs of rock needed to create Stonehenge. Now there’s a new mechanism added to the mix: balls. A combined system of ox-power, grooved rails and wooden ball bearings may have been just the trick to move 45 ton stones.

Planetary scientists in Boulder, Colorado, hypothesize that the origin of Saturn’s rings may be ice stripped off  a long-gone moon that crashed into Saturn 4 billion years ago (note: the link includes a podcast).

A new prehistoric dolphin species (and a balloon-headed dolphin at that!) was just described based on a bone found by a Dutch fisherman. You never know who’s going to be a part of the next scientific discovery…

Still looking for that perfect holiday present for that special someone? Why not name a mathematical theorem after them? After all, nothing says love like a whole bunch of cosines.

Meet the Clusterwink snail: a snail that looks, and acts, a lot like a Christmas tree light. When threatened, the fingernail-sized snail generates pulses of bioluminescent light from a single spot on it body and the snail’s opaque shell diffuses the blue-green spectrum of that light, making the whole shell glow.

Massive volcanic activity may have played a big role in the Permian Extinction and the death of the dinosaurs.

 

New Museum Update – The Walls are Coming Up

by Terry Burton, Digital Media Coordinator

Laying down the "mud slab" at the new museum construction site

Since breaking ground in September, construction has been proceeding apace at the new museum site. Practically all of the work so far is at or below the surface — hundreds of helical foundation piers have been drilled into the ground, a low concrete wall has been poured around the perimeter of the building, runs of PVC plumbing and venting pipe have been placed, and the working floor, or “mud slab,” is being laid. Every time we go to the site, it looks amazingly different. And starting this coming Monday (12-20), it’s going to look really different — the walls are arriving!

The outer walls of the museum building will be assembled from 89 custom precast concrete sections, built by Stresscon Corporation in Dacono, Colorado. We’re using precast wall sections for several reasons: they are environmentally friendly, they last longer than other construction methods, and they provide an array of beautiful finishes to choose from. Assoc. Director Jason Wolvington and I are heading down to Stresscon this morning to watch the first batch of wall sections being loaded on flatbed trucks for delivery on-site Monday. When they arrive Monday, a giant crane will unload them and they’ll be welded onto the foundation wall. Over the next three weeks, the new museum building will look like it’s literally rising up from the ground.

Stayed tuned for updates and photos. Keep an eye on our Flickr site for photos, follow us on Facebook, and check out the panoramic photos of the construction site that we’re posting on our website. And as always, if you have any questions about what’s going on, please don’t hesitate to ask!
