Inflating a set of cat lungs
Lungs are by most accounts mundane. Everybody has them, few give it much thought. But sequestered within darkness of the chest cavity, enveloping the fluttering heart, there’s an incredible wonder to this oddly inflatable organ.
Dissection is a destructive process. Rudely excised from membranous mooring and nourishing vessels, the deflated lungs appear little more than bloodied meat; amorphous and exposed…….until a breath of air unfurls its secret glory.
Here, a set of cat lungs is inflated with a straw. Comprised of hundreds of millions of microscopic air sacks called alveoli, mammalian lungs harbor air capacity that is difficult to believe unless seen. The color of the entire organ lightens into a soft pink, as each microscopic sac fills with air.

Kids, don’t try this at home, OK?
So gross, but so cool….we can’t stop looking at this.

We asked Senior Paper Conservator, Kathy Ludwig, about the most interesting project she’s worked on. The most intrinsically valuable document she has treated at the National Archives is the Monroe Doctrine. The document is the Senate version the 36-page text of President James Monroe’s seventh annual Message to Congress on December 2, 1823. The Monroe Doctrine, hand-written by an administrative assistant and signed by the President, was a defining moment in American foreign policy. We’ll explore its conservation treatment in the next few posts.
Online shopping might seem the norm today, but a decade ago retail stores were still figuring out how to market their product online. Listen to this archival piece from 2000, talking about how traditional stores were deciding how/when to enter the online marketplace.
Because teenagers need eight to nine hours of sleep, waking up at 6 a.m. can lead to a pattern of sleep deprivation. And that puts them at higher risk of a whole range of potential problems, from depression to automobile accidents. Now, some parents are pushing for later school day start times.
Two Americans, James Rothman and Randy Schekman, and Germany’s Thomas Sudhof won the 2013 Nobel prize for medicine or physiology for research into how the cell organizes its transport system, the award-giving body said on Monday. Live blog: http://reut.rs/nobel2013
"Through their discoveries, Rothman, Schekman and Sudhof have revealed the exquisitely precise control system for the transport and delivery of cellular cargo," the Nobel Assembly at Sweden’s Karolinska Institute said in a statement when awarding the prize of 8 million crowns ($1.2 million).
Medicine is the first of the Nobel prizes awarded each year. Prizes for achievements in science, literature and peace were first awarded in 1901 in accordance with the will of dynamite inventor and businessman Alfred Nobel.
