Gleanings of the Week Ending March 14, 2015

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Karnak: Excavation yields 38 artifacts - New techniques and new finds at Karnak.

71% of Investors Are Interested In Sustainable Investing - It’s positive news that more people are voting for sustainability via their investments.

New Study Pinpoints Where Ocean Acidification Will Hit Hardest - Not only hardest…but earliest. The ocean does not acidify uniformly. Estuaries with excess nutrients will acidify more rapidly. Not a good new message for the Chesapeake Bay’s shell fish industry.

Boosting older adults' vision through training - The core of the message from the research was positive but it was frustrating that the next steps were all about more research. If the initial research finding holds - then why is there not already a strategy activity to think through how vision training could be delivered to larger numbers of people at low cost.

By separating nature from economics, we have walked blindly into tragedy - We live in complex world…making decisions based on simplifying assumptions that ignore the environment or economic or social aspects are perilous.

New research into materials for tooth fillings - The composite that is most common right now is problematic because it requires adhesive to bond to the tooth, needs to be illuminated with a lamp to harden, and needs to be replaced more frequently. A new material - glass ionomer cement - may be the filling material of the future.

Widely Used Antibiotics Affect Mitochondria - The environmental accumulation of tetraclines might be harming us in ways that are just now being studied. Scary.

Epoch-defining study pinpoints when humans came to dominate planet Earth - Two dates jump out: 1610 with the irreversible exchange of species between new and old worlds and 1964 associated with the fallout from nuclear weapons testing. Either way - humans have driven Earth into a new epoch…the Anthropocene.

Fun Parks to Visit in the Top 10 Cities for Wildlife - Staycation fodder. There are interesting parks in most areas of the country. These 10 are clearly the tip of the iceberg!

Did Neanderthals make jewelry 130,000 years go? Eagle claws provide clues - From a site in present day Croatia dating from 130,000 years ago.

Coursera - February 2015

Only two courses in progress for me right now! It takes a lot of will power to not sign up for more; there are competing activities this month: travel and classroom-based courses. Here are the two that will keep me busy in February.

Circadian clocks: how rhythms structure life (from Ludwig-Maximilians - Universitat Munchen (LMU) is off to a good start with a mix of history of the research and vocabulary. It’s a topic that is interesting and has lots of implications for health and well-being.

The Land Ethic Reclaimed: Perceptive Hunting, Aldo Leopold, and Conservation (from University of Wisconsin-Madison) started off by having student pick an avatar that reflected their perspective of the course topic. I chose ‘naturalist;’ it will be interesting to see the demographics of the other students in the course. I like the way the instructors are using surveys and probing questions along with the typical MOOC videos, reading list, and discussion forums.

Two courses finished in January:

Recovering the Humankind’s Past and Saving the Universal Heritage (from Sapienza University of Rome) was a more philosophical course than I expected. It included discussion of the science/technology of archaeology and how it developed over time which is what I expected. But the more thought provoking parts of the class were about the concept of ‘universal heritage’ and why it is important; the relationship of wars and destruction of material culture of the past is striking. It happens alongside the human lives lost and plight of refugees in Syria and Iraq.

Origins - Formation of the Universe, Solar System, and Life (from University of Copenhagen) was a very broad course taught by a team of people from the Natural History of Denmark. It was a good update on what has been discovered since I was in college in the 1970s. Scanning Science Daily over the years helps - but it was refreshing to get a fresh update that tied it all together in an organized way.

As usual - I thrive on having some new topics to learn about and Coursera is a prime avenue for that. Hurray for Coursera!

3 Free eBooks - January 2015

There are so many good eBooks available these days. My favorite source is the Internet Archive because it brings together other repositories and displays them in several formats. I like the ‘Read Online’ format when I am read on my laptop and PDF when I reading on my tablet. The Kindle and Full Text formats often are not as good because the transition from the image to digital text is not corrected….and I prefer to have the illustrations inact!

Bezold, Carl. Ninive und Babylon. Bielefeld und Leipzig: Verlag con Velhagen & Klafing. 1903. Available from the Internet Archive here. I wondered as I looked at the black and white photographs how many of these items were still whole and close to where they were originally found. In the early 1900s archaeologists carted items back to their native countries. The trend now it to keep items of material culture closer to where they are found --- although that is problematic when wars erupt and the museums and sites are caught up in the destruction such as in Iraq and Syria in recent years.

Burn, Barbara (editor). Masterpieces of The Metropolitan Museum of Art. New Haven and London: Yale University Press. 2006. Available from the Internet Archive here. So many treasures….a ‘coffee table’ book with lots of wonderful photographs. Last month I included a Degas ebook from the museum (and from their site); I was surprised, and thrilled, that so many of the museum’s books are also on the Internet Archive!

Bois, D. Atlas des plantes de jardins et d'appartements exotiques et européenes. Paris: Klincksieck. 1896. Available on the Internet Archive here. I can’t resist books of botanical prints. Many are easily recognizable - like the hibiscus below.

Coursera - January 2015

The beginning of January is the lull period for Coursera courses just as it is winter break/between semesters for the universities that provide the content. I did two on-demand courses during the lull. I’ve finished all the videos for Introduction to Sustainable Development from Columbia University and am enjoying the first modules of the Astrobiology course from the University of Edinburgh.

The Sustainable Development course more about ‘why’ we need to do it rather than ‘how.’ It meshed well with the course from National Geographic about Water and the US Food System course from Johns Hopkins earlier this year. It is almost overwhelming how the big issues of our time are so interrelated.

The Astrobiology course also links well with other courses: The cosmology section of Philosophy and the Sciences (also from University of Edinburgh), Origins (from University of Copenhagen) and the Exoplanets course (from University of Geneva) that I finished last summer.  Having some of the same evidence discussed from a slightly different perspective deepens my overall understanding.

I struggle a little with the accented English of the lecturers in the Recovering the Humankind’s Past and Saving the Universal Heritage from Sapienza University of Rome…but I am still filling in some gaps in my knowledge.  It too links to some other courses from earlier this year - particularly The Art and Archaeology of Ancient Nubia from Emory University and Archaeology’s Dirty Little Secrets from Brown University.

Two new courses will start in January. Both are quite different that the courses I have taken recently….and are from universities new to my Coursera experience.
