Ten Days of Little Celebrations - January 2015

Noticing something worth celebration each day is an easy thing for me to do. The habit of writing it down reminds me to be grateful for these and a myriad of other things in my life. This month has been full of ‘little celebrations’ - as had been the usual for the past few months. Here are my top 10 for January 2015.

Winter

Snow in Tucson. The year started off with a pictures from my daughter of the snow they got --- on the palms and cactus near their apartment. It was a beautiful scene to celebrate the New Year.

Fox. A healthy looking red fox walked through our back yard then trotted behind several other houses before turning into the forest. I watched from the window of my office - celebrating the grace of the animal as it moved through the winter landscape.

Fog. The forest and our neighborhood filled with fog. The temperature was in the upper 30s. It seemed like the fog damped sound as effectively as it did sight - celebrating a warm house in the isolation of winter.

Snow. Snow that falls when I can simply stay at home until it melts or the streets are cleared by the plows is my favorite kind of day. It is the classic winter scene worth celebrating.

Other

Dishwasher. Our dishwasher became very loud so we arranged for servicing - anticipating that it would have to be replaced. Hurray! It was quickly fixed and our kitchen is a quieter place.

Zentangle® class. I saw a blurb about a Zentangle class offered at the local 50+ Community Center. It was a good incentive to investigate the place! I’ve been to the first of four class sessions and am enjoying daily ‘tangling’. I’ll post a slide show of my creations once I’ve accumulated a few more. I’m celebrating both the class and learning about the 50+ Community Center.

Arizona and Tucson

Bald Eagle. In recent years, the bald eagle population has increased on the east coast and we see them more often….but when I saw one as we drove into Grand Canyon National Park - settling into the top of a pine tree - it was a first sighting in the west for me. Hurray!

Grand Canyon. Awesome place. I’ve been there before --- it is worth celebrating again and again.

Painted Desert/Petrified Forest. The times I’d been before were in summer and late spring. This time it was decidedly cool/cold. The colors were deeper in Painted Desert because it had snowed/rained. The Petrified Forest glistened when the sun came from behind the clouds. Both places are special…and worth celebrating.

Tree Ring Lab. I’m celebrating that the place lived up to my expectations - interesting from scientific, architectural and historical perspectives. If I lived in Tucson - I’d sign up as a volunteer docent.

Gleanings of the Week Ending January 24, 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.

Is it possible to reset our biological clocks? - I have just started a Coursera course on circadian clocks so am paying more attention to articles on the topic. This one is from ScienceDaily.

Wild pollinators at risk from diseased commercial species of bee - Honeybees, bumblebees, and social wasps  are all colony living insects that makes the transmission of disease within the colony very rapid…and now there is evidence of transmission between colonies, even colonies of different species.

Google Talking To Automakers about Building Autonomous Cars - I would like to see autonomous cars…but is it just wishful thinking for the near term (say 2020)?

This Ancient Pigment Could Soon Be Used to See Through Your Skin - Egyptian blue (calcium copper silicate). And now it’s becoming a medical technology too. Other applications of Egyptian Blue in an article from Antiquity Now.

How to Uncover a Skeleton’s Secrets - From National Geographic. The examples in the article is from a project in northern Peru

One Scientist's Race to Help Microbes Help You - There has been a lot discovered about the human microbiome…but translating the new knowledge into treatments has been slower. This is a story about the American Gut Project - a massive citizen science experiment - which is focused on accumulating enough data to enable the move toward treatments sooner.

Humanity Is In the Existential Danger Zone, Study Confirms - Scary stuff. Are we engineering a wave of extinctions on our planet that will eventually include ourselves? We are pushing against and past several planetary boundaries.

A Smart Grid Infrastructure Demands Increased Engineering Smarts - One of the skillsets needed for the future. The article is about the program in Syracuse University’s College of Engineering.

Counties Lag Behind National Recovery, Report Finds - A breakdown of ‘recovery’ at the county level reveals key economic indicators on a more granular level that we usually hear about. The clickable version of the map is available here.  I found that the county where I live has recovered 2 of the 4 indicators (which is considered ‘recovered’) but where my daughter lives in Tucson has not recovered any of the 4; having visited Tucson for the past 3 years, I do notice that things have improved - but they are not back to the levels prior to 2008.

Breathtaking Frozen Bubbles Look like Elegant Glass Ornaments - I hope we have a cold day soon so I can try making frozen bubbles like this! I’m pretty sure it takes lots of practice to make them look as good as these!

Touring the Laboratory of Tree-Ring Research

I enjoyed the docent led tour at the Laboratory of Tree-Ring Research at University of Arizona last week. The Bannister Building, where the lab is located is quite distinctive - with a scrim of articulated metal tubes. The wind was not blowing on the morning of our tour so we didn’t hear the sound of the tubes in motion.

Inside we wondered around the lobby before the tour. I was looking for various ways the large tree cookies were labeled. I liked the simple white arrows that showed the semantics used: pith, early wood, late wood, branch trace, fire scar, cambium and bark.

Here is a closer look to understand what a tree ring is (the center of the tree cookie is to the lower left of the image). Note that the rings are not all the same…their width reflects the growth conditions for the year they were growing.

And some trees live for a very long time. The labeling on the tree cookie from the Giant Sequoia that lived 1704 years is labeled with more information.

When the docent arrived, we were invited upstairs into one of the labs to talk with one of the researchers who showed us how the sample cores from trees are collected and mounted. The tree-ring lab is multidisciplinary; many specialties are required to glean the information from the samples. I was intrigued by the cross section on one of the upper floors that was very different than concentric rings. This would take a lot of finesse to interpret!

I’ve included two close ups to show the dates labelled on the specimen.

One other tidbit I picked up from the docent: on the elementary school tours, the children are given a small tree cookie (~3 inches in diameter) and the children sand it to reveal the tree rings! That would certainly be a memorable learning experience!

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.

Under-the-Radar Environmental Stories for 2015: The Furtive Five - Five stories and some comments about trends in environmental reporting in mainstream media. Did you know that 33% of the children living the Tehran have asthma or air-pollution related allergies?

Technology to recycle all type of plastics without using water - This sounds like a good technology for the future…and in areas where water is already scarce.  The research/development was done in Mexico.

Chitosan: Sustainable alternative for food packaging - Chitosan is made from shells of crustaceans. The process for manufacturing is not currently economical but could become so….and the material biodegrades much faster than the 100-400 years it takes for most plastic packaging today. I wondered if the packaging would cause people with allergies to shellfish a problem. The research/development was done in Spain (Basque Country). This and the article just above caused me to wonder if countries other than the US are surging ahead when it comes to enablers for a sustainable Earth.

Sweet potato leaves a good source of vitamins - I just discovered that sweet potato leaves are edible from my CSA last fall. It’s thrilling that they are very nutritious as well. I liked them a lot in salads; they are best if eaten within a few days of being picked so I don’t anticipate they will find their way into grocery stores very often.

6 Birds That Are Champion Flyers - Champion flyers from different perspectives: Arctic Tern, Bar-tailed Godwit, Peregrine Falcon, Grey-headed Albatross, Hummingbird, Purple Martins.

The Chemistry of Decongestants - This was a timely post on the Compound Interest site.

Lose Yourself in These Photos Of Europe's Most Magnificent Libraries - Books and buildings….what will they be in 100 years? They already have a museum quality.

The 19th-Century Photography Trick That Changed How We See Snow - How William Bentley made his famous images of snowflakes….spurs me on to try more snowflake photography next time in snows in my area. I may add a feather to my supplies!

The Daily Routines of Famous Creative People, Charted - Is your daily pattern similar to any of these ‘famous creative people’?

‘Kitchen of the future’ here, now - I like the idea of a high definition backsplash! There is a film available from the location of the materials for the Science Daily story here. I already use my ceramic cooktop as working surface when I’m not cooking on it…so I agree that there are certain components of the ‘kitchen of the future’ that are now.

Six ways city landscapes can be more flood resilient - in pictures - With rising sea levels - more cities will be looking at flooding mitigations. These are some beautiful solutions. In our area of Maryland - rain gardens are often included in new housing developments.

Sustainability - Join a CSA

Joining a Community Supported Agriculture (CSA) farm is often a good step toward living more sustainably.

• Generally the farms are already certified as organic or heading in that direction because their customers demand it….and “organic” is the closest we get to sustainable farming.
• I found that I had less waste with the CSA because the veggies were ‘just picked’ and remained edible for longer once I got them home. I also learned that parts of plants that I used to throw away were actually edible (carrot tops and sweet potato leaves, for example). This is even more important in households where composting is not possible and food waste is part of the trash headed for the landfill.  We should all be striving to minimize our contribution to the landfills.
• Generally the packaging done by the CSA is minimal. Mine provided reusable bags at the beginning of the season and I could use my own mesh bags for things like spinach leaves, green beans, and small potatoes.  Sometimes the cherry tomatoes came in pulp paper bins; they are recyclable but I think next year I’ll transfer them to my own bag and just leave the bin with the CSA for them to use again. The only ‘trash’ I haven’t quite decided how to avoid are rubber bands they used for portions of onions, carrots, beets, etc.
• Another aspect that makes the CSA option more sustainable may be fuel costs for transport and post-harvest processing. The farm is less than a mile from my house. The veggies are harvested and picked up on the same day so there are minimal costs for refrigeration. The barn where the shares are picked up by participants is not air conditioned.

My first experience with a CSA was last summer and I am now a huge fan of the concept…and my particular CSA. It supplied produce from June through October. Maryland is too far north for it to operate year round (like they do in Arizona, for example). I really am missing it this winter. There are more CSAs popping up all the time; joining one is a way to begin living more sustainably (and most likely eating better too).

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.

Birding in the National Parks: Return of the Snowy Owls - It looks like this winter will be another one for seeing Snowy Owls in the northern states of the US! There were some sightings in Maryland last winter so I am hoping…

Did Venus Once Have Oceans of Liquid Carbon Dioxide? - Maybe the geological features on Venus (rift valleys, river-like beds, and plains) were may be liquid carbon dioxide rather than water like they are on Earth.

From the Feature Well - This is the summary of 2014 special issues from The Scientist. Looking back at them provides a good review of Biology issues and progress for the year.

The "Rule of 50" Helps You Know When to Give Up on a Book - How do you know when to quit reading a book? Usually I decide via scanning before I every start reading rather than determining ahead of time a number of pages I’ll read before deciding. I can’t remember the last time my scanning failed.

Monarch Butterflies May Soon Be an Endangered Species - The population has declined by 90% since the 1990s. It’s very sad. The agricultural changes in the mid-90s killed the milkweed (food plant for the caterpillars) at the edges of fields. Now there needs to be a concerted effort to increase the availability of milkweed.

The Most Amazing Meteorological and Space Observatories Ever Built - Beautiful and functional architecture from around the world.

Top Planning Trends – 2014 - A look at traffic data on Planetizen…popular tags overall and popular posts for each state. The most popular post for Maryland was about high-rise, mixed-use suburban developments.

Significant link between daily physical activity, vascular health - These type of studies come out frequently…with some nuance defined a little better than before. Hopefully no one is waiting for another study to transition some sedentary to active time every day. Now that I think about it - do these studies prompt people to become more active?

A Look Back at Our Most Popular Photos of 2014 - From the National Wildlife Federation. The very first one (a snowy owl) caught my attention.

National Park Service Launches Website Honoring 22 World Heritage Sites in the United States - Did you know that there are 22 World Heritage Sites (a UN designation) are in the US?  Most of them are National Parks…but now all. The list can be found here.

2014 in Numbers: Huge Valuations, Shocking Security Stats, and a Big Climate Deal - Factoids for the year. The last one was the one that caught my attention the most 4.4 zettabytes = all digital information in the world….and it is growing by 40% per year!

2014: An amazing year in space exploration - Philae, Orion, SpaceX Falcon 9, and Mar Rover Opportunity setting off-Earth, off-road distance record.

2014 in Materials: Rhubarb Batteries, the Gigafactory, and Printing Body Parts - It’s hard to keep up with all the innovations. How fast can any of these really get to market and be affordable?

Researchers create method that recovers high value metals for industries while protecting the environment - A step in the right direction. Hopefully the metals recovered will be valuable enough to drive the technology from the lab to application.

The Year in Pathogens - Ebola tops this list from The Scientist.

2014 in Computing: Breakthroughs in Artificial Intelligence - Seeing the aggregate for the year….2014 was quite a year for AI in a number of areas.

2014 in Energy: The Year in Energy and Climate Change - Increased urgency of warnings….only slow progress. Frustrating.

Young entrepreneurs innovate in green energy with an in situ organic waste digester - Kudos to the young Mexican entrepreneurs….and the company that is implementing their innovation.

American cities are many times brighter at night than German counterparts - The US could learn from German….and help us all see more stars in the sky too.

Social Media Sites Offer a Nice Sampling of Winter Scenery in Parks - Winter brings a different perspective.

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.
