Science is Fun Fridays!

  Dr. Rufus B. Weaver and the nervous system of Harriet Cole. Harriet worked on the custodial staff at Hahnemann Medical College in the 1880's.  At the age of 35, she died of tuberculosis, after having willed her body to Dr. Weaver. A professor of anatomy, he carefully extracted her entire nervous system.  Nerves were first wrapped in gauze for protection, and then each strand was covered with a white, lead-based paint. The display served as an educational tool, but he also took it to the Chicago's World Fair in 1893.  He received the blue ribbon for Premium Scientific Award. In the 1960's, Dr. George Geckeler performed a restoration. Ms. Cole now resides at the Drexel University College of Medicine.

Hump Day History

Image
  In April of 1800, John Adams approved legislation to appropriate $5,000 in order to purchase "such books as may be necessary for the use of Congress." On this day in 1814, the British burned the Capitol, and more than 3,000 books were lost. Thomas Jefferson responded by selling his collection of 6,487 volumes to Congress. By 1851, when a second fire broke out, there were 55,000 books, and nearly 2/3 were destroyed.  Within a few years though, the majority of books had been replaced. Today, there are more than 17 million books and millions of maps.  The Library of Congress is one of the largest in the world. The remaining Jefferson books are on permanent display in the Great Hall, as part of the Rare Book and Special Collections Division. "I cannot live without books." Of note, it's also Bucket List Day, and this is on mine.  I went to Washington DC when I was in middle school, and certainly appreciated what I saw and learned, but Hubby and I have talked about

National Parks Week

  The famous tunnel view from Yosemite. On this day of National Parks Week, we learn about the innovative projects happening in the parks. When we visited in 2015, they were restoring the Mariposa Grove of Giant Sequoias.  This year they are working on traffic flow and shuttle stops as well as campground rehabilitation. Conservancy will be done surrounding Bridalveil Falls, to reduce crowding and protect natural resources.  (It wasn't flowing on our trip). The park is also establishing a new welcome center, but here is their first. Built by the Sierra Club in 1903-04 to honor charter member, Joseph LeConte, the memorial served as an information center at the northern terminus of the John Muir Trail. "It demands of those seeing it for that first time that they reorganize their sense of proportion about the real world."

  Scientists have caught an evolutionary event in real time - primary endosymbiosis is thought to have occurred only two other times in the history of life on Earth. That is when two lifeforms merge, one engulfing the other, using it like an internal organ.  In exchange, the host cell provides nutrients, energy, and protection. The first time this happened, an archaea swallowed a bacterium that became the mitochondria, "the powerhouse of the cell." The second time, some of those advanced cells absorbed cyanobacteria that could harvest energy from sunlight, becoming chloroplasts, and giving us plants. And now, a species of algae has engulfed a cyanobacterium that allows them to use nitrogen fixation - combining nitrogen from the air with other elements to create more useful compounds. The scientists will continue studying these nitroplasts. NewsAtlas

Shoutout - Shirley Temple

Image
  Her birthday is coming up next week, but today is Animal Crackers Day, so there's this. This was on some sing-a-long cassette we had, so it's long been in my life.   I told my mom I wanted to dance like Shirley, but I only lasted a few intro classes. And surely you've had a Shirley Temple. Grenadine with ginger ale and/or lemon-lime soda. Add some vodka to make it dirty.  ;-) Top with maraschino cherries!
